INTRODUCTION
10 VSA Chapter 158 authorizes the Secretary of the Vermont Agency of Environmental Conservation to create a Fragile Areas Registry. In the word of the law, "'Fragile Area' means an area of land or water which has unusual or significant flora, fauna, geological or similar features of scientific, ecological or educational interest".
Expanding, 'the Secretary shall consider for designation...only a site which:
These specifications require two important considerations: one, that the process of registering fragile areas be a selection of those areas that are truly "fragile" and two, that registration includes not only areas that are types of landscapes (e.g., alpine areas, marshes, etc.) but also habitats for certain critical species of plants and animals. Further, words such as "significant", "exemplary" and "unusual" mean judgements must be made as to the inherent value of an area to the state's natural history, in comparison to other similar areas.
Several inventories and lists of state natural areas have been made, and their information will be invaluable in the creation of the Register. However, the Register cannot adopt the contents of these lists wholesale; all areas must first be subjected to the processes which will classify them and assess their importance to Vermont's total natural heritage. Only having been so processed can they acquire Fragile Area status. By way of illustration: Molly Bog, Peacham Bog and Franklin Bog are on most lists of important state natural areas, as bogs. But they have not arrived on the lists as the result of a systematic and standard method of selection which defines their actual character. Rathen, they have been selected largely on their traditional reputations as fine bogs. That is not in and of itself bad but leaves many questions unanswered. In what precise ways are these areas indeed fragile? Do they have comparable fragileness or does one have some special merit beyond being a "bog' -- such as being the nesting site for an endangered species of bird?
The Fragile Areas Registry proposed here must start from a new base and incorporate existing information and data into a new structure that will categorize Vermont's natural diversity. And for it to reflect that diversity and be complete, standardized and operational, it should contain the following:
-- include all reasonable components of Vermont's natural and geologic history, since fragile areas may belong to or represent any facet of the natural world.
-- be organized into legitimate natural groupings, associations or entities that facilitate classification.
-- be constructed to accommodate revisions and adaptations without forcing the entire system to be revamped.
A few additional points should be made here.
The Register is nonregulatory. It is intended to identify and document critical areas, provide information and assistance to people and organizations owning them, heighten public awareness of the areas so that they will not be destroyed inadvertently and aid in local or state planning. Great care must be taken lest areas suffer under pressures due to increased visibility, however. Registration of areas wholely or partly in private ownership, will, by itself, impose no restrictions or controls beyond those already in existence.
The Register is to be ongoing and open-ended. That is, it must be flexible enough to incorporate refinements in the classification and assessment schemes, process newly-discovered areas and react to changes in species/area status. An important part of the Register will be a mechanism for regular review, revision, addition or removal of areas from the Register. Essential work for the future will be outlined and recommended.
The Register should appeal to the general public (through whose will the law was enacted) and not just to scientists. Thus, it will be published as an easily read, visually appealing document that will encourage people to participate further, but under proper guidance and procedures. The $ 5,000 appropriated for the Register will be used for its publication and distribution.
CLASSIFICATION SYSTEM
The system described here employs both an areas and species approach to the organization of our knowledge of Vermont's fragile areas. That is, an area may be deemed fragile for any number of reasons, but reasons which fall into two major categories: landscapes (areas) (e.g., bogs, cliffs, virgin forests) or habitats for critical species of plants and animals (e.g., sites of colonial nesting birds, habitats for endangered plants). Of course, many areas qualify as both. This combined approach emphasizes the need to look at whole systems as well as critical components within systems: an entire community or a single member of a community may be fragile. The intent of the Register, whether in regard to a rare landscape, ecosystem or habitat for an endangered plant or animal, is the same -- to identify and protect areas in Vermont which are in some way vital to the state's natural systems.
Therefore, the classification system must cover a many contingencies as possible. In other words, it must account for situations in which "fragileness" may occur, even if to our present knowledge such situations do not exist in the state. It must also organize these categories into comparable units so that like-areas may be assessed by the same set of criteria; it is obvious that an area being considered as habitat for the Indiana Bat (an endangered species) should not be judged by the same criteria as an area being considered as a virgin hardwood forest.
The outline below is followed by an explanation of the categories and the rationale for using them. The categories are narrow enough to cover the array of the state' natural systems, but broad enough to avoid the endless subdivisions which would make the classification process tedious, cumbersome, and virtually unmanageable for the scope of this work.
PHYSICAL FEATURES
Bedrock Features
Surficial Features
Marine Features
Aquatic Features
BIOLOGICAL FEATURES
Flora
Fauna: mammals, birds, reptiles, amphibians, fish, invertebrates
This outline is a synthesis of systems used in other states and in the federal government, modified for Vermont's specific and present capabilities. Some states have quite elaborate systems, stemming from substantial funding and long existence, and we may profit from their experiences. The following programs have been most consulted.
Maine Critical Areas Program
Natural Areas Criteria Committee of the New England Botanical Club, Inc.
Vermont Natural Areas Project
National Heritage Program
The Nature Conservancy
Illinois Nature Preserves Commission
New England Natural Resources Center
Society of American Foresters (Research Natural Areas)
Specific references to their reports are cited at the end of this section.
The entirety of Vermont's natural and geologic history falls into one of two major subdivisions: physical and biological components. For our purposes, the important constituents of the two subdivisions are shown in the outline and elaborated here.
PHYSICAL FEATURES
The physical landscape of Vermont includes bedrock features, surficial deposits due to glaciation, wind or other force and aquatic features such as lakes, ponds and rivers. Out of the vast array of physical formations in the state, relatively few would be considered "fragile" in a structural sense, but many are excellent representatives of a geologic-type or are exemplary or important for educational purposes. Many could be adversely affected by development or other disturbance. The fragility of physical features, therefore, are judged differently from biological features in their subsequent evaluation.
Bedrock Features. Those significant features in Vermont which are due to igneous, metamorphic or sedimentary geological processes. Included in such a category are outcroppings, mineral deposits, caves and sites with fossils. Sites may be important for their shape or content, or both.
Surficial Features. Any significant depositional or erosional formation due to ice, wind or water action during the Pleistocene or Post-Pleistocene period. Examples:
-- continental glaciation: erratics, kames, striae, moraines.
-- valley glaciation: cirques, deltas, kame terraces, terminal moraines.
-- significant post-glacial features: sand dunes, special soiltypes.
Marine Features. Significant features due to forces of marine origin during the glacial or peri-glacial time, mostly associated with the Champlain Sea or Lake Hitchcock. Included are erosional (gravel beaches, sea caves) and depositional (ancient delta dunes) features.
Aquatic Features. In the physical context here, these are bodies of water with unusual natural (undisturbed) qualities and exhibiting exceptional features of their type (e.g., river with features illustrating youth, maturity and old age). Such hydrologically-influenced plant communities as peatlands, marshes and swamps are dealt with later in separate categories. Bodies of water do not merit registration solely on the basis of wild, scenic or remote attributes.
BIOLOGICAL FEATURES
Biological features may be initially identified as either plant (flora) or animal (fauna). By direction of the Vermont law, areas here are to be designated fragile which are (1) significant in their own right or (2) critical habitat for "rare, remnant or other unusual plants or animals" or "necessary wildlife habitat". Therefore, whether for flora or fauna, we have three distinct kinds of areas to consider:
-- Representatives of significant plant ecosystems/communities.
-- Essential habitats for endangered or threatened species.
-- Habitats for species (not endangered) that have special habitat requirements (usually seasonal) without which they, as species, would not survive
Flora
Many systems have been devised to identify and classify natural plant communities from the world-wide down to the local (microenvironmental) view. In this classification, we have drawn on several sources for those communities which either exist in Vermont or have the possibility of existing here, though we may not have discovered them as yet.
The basic approach is to consider climax communities (formations and associations as defined by Clements (1916)) since they tend to be the most stable and persistent. However, some important components of the state's natural systems are not climax; several are long-term seral stages (pre-, post- and sub-climaxes) and yet merit preservation and recognition for a number of reasons. Also, it may be that certain critical species (either plant or animal) depend upon habitats in an early stage of succession and, therefore, man must actively manage the areas to maintain the species.
Thus, for purposes of classifications, no attempt has been made to exclude any community type, regardless of the degree of stability or promise of persistence. Determination of an area's appropriateness to registration is part of the evaluation process later.

Black Spruce - Balsam Fir (fresh to moist)

Pitch Pine-Oak (dry)
Eastern Red Cedar (dry)

Fauna
"Fauna" encompasses all members of the animal kingdom, vertebrates and invertebrates alike. For purposes of this Register, the major classes of vertebrates are considered: mammals, birds, reptiles, amphibians and fish. Invertebrates are considered as a group. Included are species which are year-round, permanent residents of the state (nonmigratory) and those that are transitory migrants which spent only part of their lives here.
Areas deemed essential for the protection and enhancement of endangered and threatened species or for species with special habitat needs (without which they, as species, would be extirpated in Vermont) will be registered.
Categories for all Classes
Specific groups of animals require special considerations:
Birds
Amphibians & Reptiles
Invertebrates
Little information available, especially related to potential endangered or threatened species.
EVALUATION SYSTEM
Once an area has been classified as a potential fragile area, it may then be processed for final designation on the Register or dropped from consideration. That is, it must be determined to be truly "fragile"; also, it may be that an area, even though fragile, is not suitable for inclusion in this Register -- for example:
-- an area may qualify initially under the category of Boreal Forest, but may actually be a mediocre example of that forest type.
-- a habitat for an endangered species may not be appropriate for registration if either the species or the area it occupies cannot be protected or managed (such as the great tracts of forest required for the territory of the Catamount).
Adamus & Clough (1978), when discussing areas for critical species, suggest considering the suitability and desirability of such species for selection: suitability means "species amenable to protection and management by a natural areas program", and desirability means "those species which deserve or need additional protection". By their definitions, not all species desirable for protection are suitable for protection via a natural areas program. We suggest employing these concepts by combining them into one of appropriateness, applying it to all area categories by means of the scheme outlined below.
Therefore, an area processed through this system, if characterized as both fragile and able to be managed or protected to preserve the entity or character in question, it will finally be placed on the Register. Essential for this last step will be confirmation of an area's attributes through citation of existing literature or through new field research.
The Evaluation System is comprised of 11 categories, each of which is a distinct measure of an area's feasibility for registration. The characteristics of each category are outlined only enough to guide the scientific advisors in their deliberations on the specific merits of each area.
Numerical ratings have been used in some natural area programs. Such a system is not used for any part of this assessment, however, since they tend to:
"...assume constants among areas when, in fact, every area is unique in its combination of elements and factors.
Cumulative value systems also risk the underrating of areas that may have one single but important attribute... By the same token, an area with a large number of factors -- none significant -- may achieve an unwarranted high rating."
-- VNRC (no date)
All 11 categories do not apply to all fragile area types, and some will carry different meanings for different types, e.g., "persistence" means one thing for an endangered species and quite another for a bedrock formation. Therefore, two provisos should be kept in mind:
NOTE: Sites representing the only known station of an endangered or threatened species will automatically be registered regardless of the results of evaluation, since for their individual categories they are ultimately fragile.
Evaluation Categories
Areas which have been thoroughly or well studied/researched will receive more consideration for registration than those which have been little or not at all studied. The better our knowledge of an area, the more basis we have to judge its true nature.
Area types (e.g., marsh, critical habitat for a bird) that are not on the Register will receive more consideration than those which are already. This will insure that the Register will cover the whole scope of fragile areas in the state and will not become overloaded with one type or another.
Areas that contain the greatest number of fragile area classification categories (see page 6) will receive the highest consideration. For example, an area that is being considered as a peatland, as a habitat for an endangered species of plant and contains a site of geologic significance, will merit greater consideration than if it were being considered for only one of those categories.
Only areas that are truly scarce or areas containing truly rare species/features will be registered. In evaluating scarcity, the following should be kept in mind:
-- A common area-type may be scarce if it is an outstanding example of that area (e.g., virgin northern hardwood forest, as opposed to second growth northern hardwood forest).
-- A scarce endemic species warrants higher consideration than one which is alien or newly-arrived to the state.
-- Peripherality: a species or community which is on the edge of its natural range in Vermont may exhibit erratic or cyclic population numbers in the state and thus may not be truly scarce.
-- The factors which contribute to endangered or threatened species' scarcity (e.g., failure to reproduce, lack of adaptability, pesticides, etc.) need be considered only for purposes of management, since such species are by definition scarce and will be accepted for registration in this category.
Areas that exhibit the least human disturbance to the natural conditions generally will receive the highest consideration. However, in some cases where recommended by the advisory panels, even much-disturbed areas may have value to the Register, especially if active management is required to maintain the character of the area (or fragile component of it) or if it can be readily restored. Susceptibility to disturbance will also be considered: areas/species more susceptible to disturbance will mean higher consideration than one less so.
Adamus & Clough (1978) use the term "site tenacity" to evaluate "the probability a species will occur at the same general site or natural area for a specified period of time (arbitrarily 25 years)". Species with high site tenacity merit greater consideration than those with low. The characteristics Adamus & Clough ascribe to each are as follows:
Lower Site Tenacity | Higher Site Tenacity | ||
1. | Inhabits earlier successional | 1. | Inhabits more mature vegeta- |
stages, or an otherwise more | tion successional stages or | ||
ephemeral site (e.g., flood- | an otherwise more permanent | ||
plain). | site (e.g., rock edge). | ||
2. | Feeds closer to the breeding | 2. | Feeds at greater distance from |
site (at least seabirds) in | the breeding site (seabirds) | ||
relatively homogeneous habitat. | in relatively homogeneous | ||
habitat. | |||
3. | Reproduces in a few large | 3. | Reproduces in pairs or many |
aggregations. | small groups. | ||
4. | Individuals with shorter life- | 4. | Individuals with longer life- |
span (e.g., annuals). | span (e.g., perennials). | ||
5. | Individual or group in question | 5. | Individual or group in question |
near the periphery of its | well within range. | ||
range. | |||
6. | Cyclic population. | 6. | Noncyclic population. |
Areas that are capable of being managed and/or protected to maintain the desired natural feature(s) will receive higher consideration than those that are not. Determination of this capability includes whether or not the areas/species are:
A species restricted to a single habitat for any part of its life cycle will receive higher consideration than one that is either:
Species that are nonmigratory or have restricted seasonal mobility are usually more feasible for registration than those that are migratory or seasonal "wanderers", if those species do not have high site tenacity (persistence) and do not congregate in large flocks during migration (e.g., waterfowl). Adamus & Clough (1978), in deciding priority order, listed degrees of mobility as:
with decreasing suitability for registration from (a) to (d).

Site Description
Mount Mansfield, rising to 4393' from a base level of approximately 1500', is one of the most striking landscape features of Vermont. Its long summit ridge, resembling to some the profile of a man's face, lies mostly above altitudinal tree line and possesses the largest single expanse of alpine vegetation in the state. At various times in its recent history the summit ridge has been the site of a hotel, a post office, radio and television towers, and transmitter houses. Since 1941 the Mt. Mansfield Company has operated a ski area on the slopes beneath the summit on the northeast side of the mountain. Despite the scope of these human activities, however, the summit ridge of Mt. Mansfield (a 200-acre area, owned largely by the University of Vermont) remains one of the most outstanding natural areas in the state. There are excellent exposures of bedrock which display evidence of the tectonic and metamorphic history of the Green Mountain anticlinorium. Many rare and endangered plant species are numbered among the mountain's tundra population, including Diapensia (Diapensia lapponica), bearberry willow (Salix Uva-ursi), Boott's rattlesnake root (Prenanthes Boottii), alpine knotweed (Polygonum viviparum), alpine bilberry (Vaccinium uliginosum var. alpinum), black crowberry (Empetrum nigrum), mountain cranberry (Vaccinium vitis-idaea), mountain sandwort (Arenaria groenlandica), Bigelow's sedge (Carex Bigelowii), highland rush (Juncus trifidus) and seven species of grass. Altogether about 40 species of plants on or near the summit ridge are of special ecological interest. Of additional interest are several small peat bogs located in wet depressions along the ridge. The bogs add still further to the habitat and floristic diversity of the area. Lake of the Clouds on Mt. Mansfield is the highest permanent body of water in the state. Bear Pond is almost as high. Both contain boreal insects not known elsewhere in the state (Bell 1980).
Critical Features
This is one of only two areas in the state in which alpine tundra can be found, and the only one of significant extent. The tundra contains many species on the Vermont rare and endangered species list, as well as other unusual apline species. Heavy foot traffic in the summer and fall requires constant monitoring by ranger-naturalists. The alpine bog areas are particularly fragile and require monitoring and protection.

Site Description
This area includes a 10-acre alpine tundra community (approx. 3800'-4803' elev) and the spruce-fir forest between approx. 2800'-3800' elevation. Other than Mt. Mansfield, it possesses only alpine tundra ecosystem in the state. The spruce-fir forest is in virgin or nearvirgin condition and is a prime example of a montane boreal forest ecosystem.

The tundra contains eight species on the Vermont rare and endangered species. The 10-acre summit is subjected to heavy foot traffic in summer, and the entire plant community could be irreparably damaged without proper management and protection. The spruce-fir forest is an outstanding example of its type and one of few large unspoiled stands in the state.

LAKE WILLOUGHBY NATURAL AREA
Location
Lat. 44 [degrees] 43' 0" N, Long. 72 [degrees] 02' 0" W. Orleans County. Town of Westmore. See accompanying map.
Site Description
The magnificent cliffs of Mt. Pisgah (on the east) and Mt. Hor (on the west) dropping almost vertically into the depths of Lake Willoughby, represent one of Vermont's most exciting landscapes. Both geologically and botanically this area is worthy of the wide recognition it has received. The valley was glacially carved and the combination of cliffs and lake displays classical glacial features. The cliffs of Mt. Pisgah contained one of the state's major historic peregrine falcon eyries (Stewart 1980). Presently, the state has no breeding population of this federally endangered species. The flora of these cliffs is very similar to that in Smuggler's Notch, where similar environmental conditions prevail. Some of Vermont's rarest plants grow on the wet ledges of the Willoughby Cliffs, and this area is probably the richest fern locality in Vermont, with rarities such as the wall rue (Asplenium cryptolepis), smooth and purple cliff-brakes (Pellaea glabella and P. atropurpurea), and smooth and northern woodsias (Woodsia glabella and W. alpina) all being found on the cliffs. Finally, the lake itself, 1692 acres in area, is one of the deepest in New England, and supports a large variety of cold water fish.
Critical Features
One of only three areas in Vermont with an arctic cliff flora. Remarkable diversity of rare ferns and ferns in general. Many species from state's rare and endangered list.

SMUGGLER'S NOTCH
Location
Lat. 44 [degrees] 33' 0" N, Long. 72 [degrees] 48' 0" W. Lamoille County. Town of Cambridge. See accompanying map.
Site Description
Smuggler's Notch is a rocky gap between Mt. Mansfield on the southwest and Sterling Mountain of the northeast. Here, within The Mount Mansfield State Forest, is a preserve of 1424 acres whose cliffs and ledges (from Rt. 108 to over 3000' in elevation) contain a flora that is essentially arctic in character and quite unlike the alpine tundra to be found nearby on the Mt. Mansfield summit. Many of the species growing here are not found on the other higher mountains of the East, either. The best representation of arctic-alpine flora if found on the west side of the notch where the plants grow on open and often wet, dripping ledges. These species include a large number of rare arctic calciphiles, such as the live-long saxifrage (Saxifraga aizoon var. neogaea), yellow mountain saxifrage (S. aizoides), purple mountain saxifrage (S. oppositifolia), northern painted cup (Castilleja septentrionalis), grass-leaved fleabane (Erigeron hyssopifolius), butterwort (Pinguicula vulgaris), sweet broom (Hedysarum alpinum var. americanum), tufted bulrush (Scirpus caespitosus), bird's-eye primrose (Primula mistassinica), purple hairgrass (Deschampsia atropurpurea), and felwort (Gentiana amarella). The notch is the only known station of the early sandwort (Arenaria rubella), and of the moss, Plagiobryum zierii (Worley 1980), in the eastern United States. Smuggler's Notch is also known as a haven for ferns and several of its rare species are ferns. It is known (Stewart 1980) to have been the location for one of the state's peregrine falcon eyries. Presently, this endangered species is not known to breed in Vermont.
Critical Features
A nearly unique habitat for New England with several arctic plant species at the southern limits of their ranges. An outstanding example of this kind of habitat, with a number of plants on the state's rare and endangered list.

MISSISQUOI RIVER DELTA
Location
Lat. 44 [degrees] 58' 0" N, Long. 73 [degrees] 10' 0" W. Franklin County. Towns of Swanton and Highgate. See accompanying map.
Site Description
Approximately 1500 acres of freshwater marsh and swamp forest habitat at the delta of the Missisquoi River midway between Swanton and East Alburg, Vt. The delta itself is geologically distinctive, being one of few "bird's foot" deltas in the United States and a classic display area for postglacial depositional and shoreline geologic features. The marshes contain great floristic diversity and a wide range of life forms, from fully-submerged plants (eelgrass, pondweeds, coontail and bladderworts) to extensive populations of emergent types (great bulrush, bur-reed, pickerelweed, cattail, and sedges). A splendid (Vogelmann 1969) swamp forest occurs on the seasonally flooded margins of the marsh. These forests are dominated by silver maple and swamp white oak, with black alder and buttonbush occuring as common shrub associates. These wetlands are important as feeding and breeding areas for migratory waterfowl and wading birds, and a wide variety of songbirds. They also contain the principal spawning ground in the northern part of the state for a number of migratory game fish species. The area is also an important archaelogical site for Indian antiquities (Day 1980).
Critical Features
This is a particularly rich ecosystem and a large one. The variety of wildlife and the size of the populations it supports are testimony to its size, integrity, and the quality of stewardship it has enjoyed under the direction of the U.S. Fish and Wildlife Service. This extensive wetland complex, including the river itself, is a critical spawning habitat for migratory game fish species (notably walleye, pickerel, bass, muskellunge, and northern pike, the latter being the most notable and subject (Sladyk 1980) to habitat alteration. Of the resident and migratory bird populations found in the Missisquoi delta area the following have been classified (see references) as rare or endangered with Vermont:
bald eagle (endangered)
peregrine falcon (endangered)
osprey (endangered)
yellow rail (rare)
least bittern (rare)
The area also contains one of the state's largest great blue heron rookeries. Viewed hydrologically this large deltaic deposit (Ratte 1980) has the potential for being a major source of potable ground water for northwestern Vermont.

MOOSE BOG
Location
Lat. 44 [degrees] 41' 0" N, Long. 71 [degrees] 43' 0" W. Essex County, Town of Ferdinand. See accompanying map.
Site Description
Approximately 15 acres of shallow open water, a glacial kettle pond, surrounded by another 15-16 acres of a floating bog mat, over which are distributed most of the characteristic species of bog vegetation, including sphagnum moss, sedges, pitcher plant, sundew, and a variety of low heath shrubs. The bog mat grades into a peatland of higher shrubs, and then to an open to dense forest of black spruce and tamarack. The open area and surrounding bog forest occupy approximately 330 acres. An adjacent site of an additional 150 acres (in private ownership) along the same drainage as the bog pond, containing a combination of swamp forest (black spruce and white cedar) and upland boreal forest (red spruce, balsam fir, and white birch), is also included within this area.
Critical Features
This bog is proposed for the Registry on the basis of its having features which place it in two classification categories: as a peatland, and as a habitat for bird, mammal, and plant species which are very restricted in their distribution within the state.
It is considered an exceptional boreal natural area; exceptional for its size, its wildness, and for the character of its living inhabitants.
Moose, black bear, white-tailed deer, and beaver inhabitat the bog and surrounding forest, while unusual plant populations include the rare white form of the moccasin flower (sought and removed in quantity along with the pitcher plant and other bog species by commercial plant collectors). The populations most unique to the bog and its adjacent swamp and bog forests are the birds. In the boreal black spruce forest of this area the following species are of special note because of their placement on the proposed rare, threatened and endangered list of birds for the state:
Spruce grouse (endangered)
Gray jay (threatened)
Black-backed three-toed woodpecker (threatened)
The latter has its primary Vermont breeding habitat in the Moose Bog area.
The area is also part of the largest deer yard (wintering area) in Vermont, and is crucial to the survival of the species in this section of the state.
[See graphic or tabular material in printed version]
Evaluation Categories
Ownership
The 330 acre bog/forest plot is presently owned by the Vermont Fish and Game Department as a part of its recent (May 1980) purchase of 2000 acres in the area; the adjacent 150 acre swamp forest and upland boreal forest plot are owned by the St. Regis Paper Company. The entire area was purchased by the Fish and Game Department primarily for habitat and management for white-tailed deer.
Recognition
Discovery of the biological significance of this bog has come too recently to have been included in natural area evaluation schemes. It was recognized in the Vermont Natural Areas Inventory in 1972 and included in the National Natural Landmarks Program search, without any major recognition. In view of recent findings relative to animal habitat, this area has again been proposed for Natural Landmark status. It is considered a Primary Unique and Fragile Area, according to the Vermont Breeding Bird Atlas (Laughlin 1980).

QUECHEE GORGE
Location
Lat. 43 [degrees] 38' 13" N, Long. 72 [degrees] 24' 30" W. Windsor County. Town of Hartford. See accompanying map.
Site Description
An outstanding part of Vermont's geologic heritage, Quechee Gorge is a deep (140'), narrow ravine with nearly vertical walls, cut by the Ottauquechee River. Located about midway between Woodstock and White River Jct., the gorge is spanned by the Route 4 highway bridge near its midpoint. The steep ravine slopes are forested with hemlock and a mixture of hardwood and other conifer species. Some of these forests are untouched. The wet, dripping ravine walls and ledges, accessible along the river from below, harbor a rich and colorful boreal flora.
Critical Features
The integrity of the gorge itself, with its forests, ledges and ferns and wildflowers, is the main critical feature here. Continued stewardship of the kind the gorge has seen to date should result in its persistence for many generations. Two rare ferns, the northern and smooth woodsias, are found on Quechee's cliffs near the bottom of the gorge. Both are considered disjunct in their distribution and are at the southern limit of their range.
Quechee Gorge was, for a number of years, the only known habitat for the rare ground beetle, Bembidion rufotinctum Chaudoir. This beetle demands rock ledges with a scum of algae, and must live within a few feet of the swift flowing waters of a large river. Recently it has been discovered at several additional sites in Vermont and New Hampshire. However, proposals to increase the construction of small hydroelectric power plants along New England rivers might put it in peril except at some of these other locations.

Site Description
Five acre gorge of deeply carved and highly polished boulder terrain with waterfalls, rapids and glacial potholes. Shaded by hardwood/conifer mixture.
Critical Features
As with other scenic geologic areas, the peripheral forest is probably more fragile than the site itself and requires some management and protection for the maintenance of the scenic quality of the area as a whole.

MILLER BROOK CIRQUE
Location
Lat. 44 [degrees] 28' 15" N., Long. 72 [degrees] 43' 0" W. Lamoille County. Town of Stowe. See accompanying map.
Site Description
Glacially carved basin with 1,000 foot walls and a variety of surficial geologic features characteristic of alpine glaciation. Acreage of the site between 1,200 - 1,300, surrounding and including Lake Mansfield in Stowe's Nebraska Valley. The area is defined by height of land above basin (watershed of Lake Mansfield) and geologic features adjacent to Miller Brook.
Critical Features
Within this area are contained many of the classic features of mountain valley glaciation; the cirque basin itself, moraines, kame and kettle topography, an esker delta, and a tarn lake (Lake Mansfield - now artificially impounded) at the head of Miller Brook. Considered one of the best examples of alpine glaciation in the United States east of the Rocky Mountains. An old-growth stand of hardwoods (2-3 acres) exists on the southern shore of Lake Mansfield.

SHELBURNE POND
Location
Lat. 44 [degrees] 23' 0" N, Long. 73 [degrees] 10' 0" W. Chittenden County. Town of Shelburne. See accompanying map.
Site Description
Located only a few miles south of Burlington, Shelburne Pond is the only undeveloped pond remaining in the Champlain Valley. It is especially remarkable for the fact that it still remains a semi-wild area despite its proximity to the urban sphere. The picturesque rocky shores, vertical bluffs, marshes and bogs, and wooded upland surrounding the 432 acre pond harbor a great variety of plant and animal life. Complex wetlands occupy large bays of the pond, most of its western side, and fill its outlet. There are swamp forests of elm and maple, dense alder and willow shrublands, expanses of cattail marshes and sedge meadows, and two bogs. Beaver, muskrat, otter, and many resident and migratory bird species breed in the wetlands surrounding the pond. Shelburne Pond is also a notable archaeological site.
Critical Features
Being the only major undeveloped pond ecosystem in the Champlain Valley puts a special premium on the retention of this site. Hidden in the simple designation of "pond" is a complex of wetlands of such great diversity that a biology class would have to travel little beyond its boundaries for an entire semester of ecological study. Of its diverse resident and migratory wildlife, three species - the osprey, marsh hawk, and least bittern - bear special note because of their proposed designation as endangered, threatened and rare species (respectively) in Vermont. The limestone ledges near the pond have yielded several invertebrates rare in Vermont (particularly millepedes), and are also important as overwintering sites for the marsh insects. This is one of four known localities for the rare water bug Sigara hydatotrephes, otherwise known only from Georgia and Alabama. From which habitat at Shelburne Pond this species was collected is not known.

Ownership
Sizeable tracts surrounding the pond have been acquired from private ownership by the Nature Conservancy regularly since 1973, largely through the generosity of H. Laurence Achilles. Upon purchase these parcels have been subsequently deeded to the University of Vermont, with the provision that they be used for educational and scientific purposes. The goal of the Nature Conservancy is to eventually acquire or protect through easements between 800 and 900 acres around the pond to complete this natural area. It will be known as the H. Laurence Achilles Natural Area.

CAMBRIDGE PINE WOODS
Location
Lat. 44 [degrees] 39' 0" N, Long 72 [degrees] 53' 0" W. Lamoille County. Town of Cambridge. See accompanying map.
Site Description
A splendid (Johnson 1980) stand of old-age white pine and hemlock on both sides of a steep-sided ravine with a stream at the bottom. Found within the Cambridge State Forest, behind the village cemetery, this stand is approximately 22 acres in area. Several trees are to be found within the 36-48" diameter range. A hardwood understory shows a successional trend toward sugar maple, red oak, yellow birch, and beech for the coming forest generation. The herb layer is sparse.
Critical Features
Due to the economic issues associated with white pine there are very few pine stands of comparable size and age in Vermont. This is an important forest type, both in the glimpse it offers backward in time, and in the opportunity it offers to watch succession in action - the eventual replacement of pine by hardwoods.

CANFIELD-FISHER MEMORIAL PINES
Location
Lat. 43 [degrees] 6' 12" N, Long. 73 [degrees] 8' 30" W. Bennington County. Town of Arlington. See accompanying map.
Site Description
The largest white pines in Vermont. An exceptional stand of old-growth white pine, relatively undistrubed. The stand is even-aged, with trees having diameters mostly in the 30-40" range (up to 42") and heights up to 130 feet. Most of the stand is on a moderate to steep slope, 2 1/2 mi. w. of Arlington village (the former retreat of well-known Vermont writer Dorothy Canfield Fisher). Hardwood understory shows successional trend, and favorable moisture gradient from top of slope to brook at the bottom provides for good variety among shrubs and herb species.
Critical Features
Because of its value on the lumber market few stands of white pine of this size and age exist in New England to show us the grandeur of these trees as they must have appeared to the original settlers. The present lack of such stands is an unfortunate missing link, as well, in trying to piece together the successional story of white pine. It is important that forests of a wide range of ages be a part of our landscape and ecological heritage.

LORD'S HILL HARDWOOD FOREST
NATURAL AREA
Location
Lat. 44 [degrees] 19' N. Long. 72 [degrees] 22' W. Washington County, Town of Marshfield. See accompanying map.
Site Description
The area includes a 25 acre hillside stand of mixed hardwoods and conifers (between 1,300-1,600' elevation approximately). Included in this larger stand is an approximately 13 acre, predominatly hardwood forest with trees of grand dimensions and age, deemed by some to be the finest of its kind in Norhtern New England. Among the twelve tree species reaching at least 18" in diameter, more than 120 trees measure greater than 24", including the state's largest measured sugar maple (Acer saccharum) and striped maple (Acer pensylvanicum), and second largest beech (Fagus grandifolia), yellow birch (Betula lutea), balsam fir (Abies balsamea) and red spruce (Picea rubens). Trees of several species (including sugar maple) exceed 100 feet in height and 40" in diameter. Age measurements for several species (not the largest specimens) exceed 400 years. Shrub and herb components of forest are typical; not unusually rich in species (nearly all species are native). Many breeding birds and good representation of forest mammals, including several active black bear dens.
Critical Features
Although old-age hardwood/conifer mixtures are not rare in the state, this stand shows evidence of being Vermont's finest example of this kind of forest, both from the standpoint of size and age of trees and also in having a characteristic climax representation of size and ages of trees species from seedlings on up. Such a stand represents an important example of the state's original forest cover.

GIFFORD WOODS
Location
Lat. 43 [degrees] 42' o" N, Long. 72 [degrees] 48' 0" W. Rutland County. Town of Sherburne. See accompanying map.
Site Description
A five acre stand of virgin growth of hardwood forest along the east side of Route 100, within the Gifford Woods State Park near Sherburne, Vt. The stand contains sugar maple (predominately), beech, yellow birch, basswood, hemlock, white ash, and elm, all of considerable size and age.
Critical Features
Very few undisturbed hardwood forests exist in New England. Those that managed to escape the axe, however, are likely to be very old indeed, although their individual trees may be but a fraction of the age of the forest's historic continuum. Gifford Woods represents an old-age hardwood stand, though a very small one, that quite probably belongs to the select few of its type still remaining. Its small size, multiple uses, and its roadside location, however, are all deterrents to the continued health of this forest and to its continued credibility as a natural area.

MAYNARD MILLER (VERNON) BLACK GUM SWAMPS
Location
Lat. 42 [degrees] 44' 0" N, Long. 72 [degrees] 32' 0" W. Windham County. Town of Vernon. See accompanying map.
Site Description
A rare stand (actually four small isolated stands) of old-age black gum trees growing in a swampy depression in the upland hardwood-covered hills of Vernon, just north of the Massachusetts border. Black gum is a species of more southerly latitudes, although scattered trees occur in Vermont. This stand is probably a relic from a warmer climatic period. The trees grow in a hummocky swamp of about 5 acres in area and appear quite old. Associated with black gum here are hemlock, yellow birch, and red maple, with a shrubby understory of ferns, mountain holly, withe rod, highbush blueberry, and black alder.
Critical Features
Represents not only an unusual forest type not generally found in Vermont but serves as a climatic marker from a period, somewhere between 5,000 to 3,500 years ago, when Vermont's climate (and accordingly its vegetation to some extent) was more like the climate of areas further south. The milder temperatures of the climatic optimum (Klein 1976) allowed many southern plants to extend their ranges into Vermont. Then, with a shift to colder conditions again, these plants' distributions contracted. Often small pockets of a population were left behind. These disjunct stands are exciting and important biologically. The rare Massachusetts fern (Thelypteris simulata) and Virginia chain fern (Woodwardia virginica) - both southern species - grow here. Both have been proposed for inclusion on the new state endangered species list.

LITTLE OTTER CREEK MARSH
Location
Lat. 44 [degrees] 14' 0" N.,Long. 73 [degrees] 17' 0" W. Addison County. Town of Ferrisburg. See accompanying map.
Site Description
Described by Vogelmann (1964) as "the best large expanse of marshland in Vermont", this area lies near the mouth of Little Otter Creek where several tributaries join to form an extensive area of shallow water. The flooded river channel supports a vast series of marsh communities, ranging from purely aquatic, to seasonally exposed mudflats, to shoreline tree and shrub ecosystems. An area of more than 1,000 acres, 4/5 of which is in public ownership (Vt. Dept. of Fish and Game). Many species of waterfowl and marsh birds nest here, including some on the state's endangered, threatened and rare list.
Critical Features
Given a fairly large number of extensive marshes within the boundaries of the state, it seems important to propose the acknowledged "best" of these for inclusion in the Registry. Chief among the critical features of this marsh complex is the habitat it provides for resident and migratory water birds and birds of prey. Those of special note, by virtue of their proposed placement on the rare, threatened and endangered list of birds for the state, are the following:
Bald Eagle (endangered)
Osprey (endangered)
Marsh Hawk (threatened)
Least Bittern (rare)
The seasonally flooded swamp-oak-silver-maple forests are perhaps the richest habitat in the state for invertebrates. These, and the hemlock grove that occupies the point between Little Otter and Lewis Creek, contain many unusual species. The lacustrine forest is the only locality north of New Jersey for the ground beetle Agonum picticorne. It is evidently favored by the seasonal flooding and the mild climate. On the other hand, the hemlock forest supports Scaphinotus viduus, a large snail-eating ground beetle otherwise known only from mountain forests. This area has a large population of the blue-flecked salamander, Ambystoma laterale, which is thought to be decreasing in numbers in the northeast, possibly as a result of acid rain.

BARTON RIVER (COVENTRY) MARSH
Location
Lat 44 [degrees] 53' 0" N, Long. 72 [degrees] 12' 0" W. Orleans County. Town of Coventry. See accompanying map.
Site Description
River mouth of Barton River as it flows northward into South Bay of Lake Memphremagog. Marshland and shallow meandering river channel occupy 1,545 acres at 700' elevation.
Critical Features
This extensive wetland provides and important environment for breeding and migratory waterfowl and other marsh birds and wildlife. An excellent site for encountering a great diversity of aquatic and emergent plants. This area was the site of the last documented osprey nest in Vermont (Sladyk 1980) and is considered (Stewart 1980) the state's most likely location for sighting of bald eagles. This area serves as the primary source of entrance to the Barton and Black River spawning areas for brown and rainbow trout. The spawning areas are located considerably upstream.

FRANKLIN BOG
Location
Lat 44 [degrees] 59' 30" N, Long. 72 [degrees] 53' 45" W. Franklin County. Town of Franklin. See accompanying map.
Site Description
A splendid (Vogelmann 1969) and extensive quaking bog occupying an elliptical basin of about 300 acres in the town of Franklin, Vt., about 1/2 mile south of the Canadian border and 20 miles east of Lake Champlain. It is about 1/4 mile north of Lake Carmi.
The bog is roughly zoned with a wet, sparse conifer forest on the outside, an open bog mat within, and a small pond with streams and beaver-flooded areas in the middle. The three zones interpenetrate in a complicated manner. The vegetation is complex and the flora correspondingly rich.
Critical Features
Large in comparison with most of Vermont's bogs, studies have shown Franklin to be correspondingly rich in species and particularly useful in demonstrating bog formation (Jenkins 1979). It also possesses greater stability than most bogs, also a function of its size. Difficulty with access prevents the idle sightseer from visitation and keeps the bog in near-wilderness condition.

MOLLY BOG
Location
Lat 44 [degrees] 30' 0" N, Long. 72 [degrees] 38' 0" W. Lamoille County. Town of Morristown. See accompanying map.
Site Description
In valley lowlands east of Mt. Mansfield, this bog shows several stages of development. It includes a two acre pond fringed with pond and water lilies, surrounded by four distinct zones: a shrub edge of leatherleaf; a 20 acre bog mat, composed of a matrix of sphagnum moss and sedges with many of the characteristic bog species including leatherleaf (Chamaedaphne calyculata), bog laurel (Kalmia polifolia), bog rosemary (Andromeda glaucophylla), sweet gale (Myrica gale), cranberry (Vaccinium spp.), cottongrass (Eriophorum spp.), sundew (Drosera rotundifolia), and pitcher plant (Sarracenia purpurea); a coniferous forest zone of black spruce and tamarack completely surrounding the bog; and an extensive hardwood forest, dominated by red maple, as soils improve in drainage on the surrounding uplands.
Critical Features
Considered exemplary of a postgalcial bog (Vogelmann 1964), and is particularly valuable for showing several stages of bog development, from pond to bog forest. One of only two Vermont locations for the southern twayblade orchid (Listera australis).

COLCHESTER BOG
Location
Lat 44 [degrees] 33' 0" N, Long. 73 [degrees] 17' 0" W. Chittenden County. Town of Colchester. See accompanying map.
Site Description
Area includes a 150 acre peatland located five miles northwest of Burlington on a peninsula between Lake Champlain and Mallet's Bay. The bog is largely covered with shrubs and trees, but an open quaking mat of sedge and sphagnum is present. Narrow sandy peninsula on eastern edge has several black gum trees (the species' only northwestern Vermont location).
Critical Features
Unusually rich assemblage of bog and marsh plants and has been recognized as one of the most outstanding natural areas in northwestern Vermont. Presence of Nyssa sylvatica (black gum) an important clue to warmer postglacial climate than presently exists. Has the only known plant of Betula pumila (dwarf white birch) known in Vermont, and contains highly unusual (Worley 1980) stands of pitch pine (Pinus rigida) growing in a peat substrate. Depends upon the levels of a major lake (Lake Champlain) for its ecological character, a feature shared by very few other peatlands in the United States.

DORSET BAT (GREEN PEAK) CAVE
Lat grees]43 [de 14' 15" N, Long. 73 [degrees] 2' 5" W. Bennington County. Town of Dorset. See accompanying map.
Site Description
Five acre limestone solution cave in Green Peak. The cave has two main chambers and possibly others deeper in the mountain. Both main rooms support hibernatiing bats in winter.
Critical Features
Likely the most important hibernaculum and roosting site in New England for the federally endangered Indiana bat (Myotis sodalis). Other bat species also use the cave for hibernation. Past research has documented great numbers of Indiana bats here (around 300,000 in some years), but little is known about their present status except that it is probable they still hibernate in this location. The Indiana bat is a colonial hibernator, so is especially vulnerable in winter. This cave may be the only locality in Vermont for a truly cavernicolous invertebrate, the white, eyeless amphipod Stygobromus sp. (the species is uncertain, as only immatures were included in the collection). However, there may be confusion over the name of the cave, as the specimens were labeled only "Dorset Cave".

DEAD CREEK WATERFOWL AREA
Location
Lat 44 [degrees] 05' 00" N, Long. 73 [degrees] 21' 0" W. Addison County. Town of Addison. See accompanying map.
Site Description
The largest waterfowl management area in the state is this area in western Addison County bissected by Route 17 between Addison and Chimney Point. The waters of Dead Creek flow sluggishly north and empty into Otter Creek here. Conditions for marshlands are ideal and wetland vegetation of a variety of kinds spreads over a large area (more than 1,000 acres). Several dikes have been constructed to create favorable environments for nesting and feeding waterfowl. Aquatic plants, ranging from submerged to emergent, are found in great variety and in extensive stands. One of the most important wetland complexes in the state for waterfowl and marsh birds, a total of 168 species has been found within the area to date.
Critical Features
Although some of the wetlands in this complex are the result of man-made impoundments, the basic marsh vegetation of the area was established naturally long before management began, and the migratory visitation patterns now seen here among the wildlife have been fixed for many years in the populations that use the marshes. Human visitation is relatively heavy but restricted from breeding areas during critical times. Among the many species of resident and migratory birds and mammals feeding and breeding in the waterfowl area, the following, because of their inclusion in the state's proposed list of rare, threatened, and endangered bird species, are worthy of note:
Least Bittern (rare)
Short-billed Marsh Wren (threatened)
Osprey (endangered)
Peregrine Falcon (endangered)
This area is rich in marsh insects, and is the only known Vermont locality for the ground beetle Bembidion cordatum.
Indian artifacts are abundant in the region.
