mountainous regions - from New York southward into Comment Tennessee (Conant and Collins 1991). Occurs more or less continuously in suitable habitat
throughout the Cumberland Mountains in extreme southeastern Kentucky; scattered
populations occur elsewhere in eastern Kentucky; known from a total of
about 16 counties (J.R. MacGregor
Herpetology Maps 2004). S-Trend Unknown S-Trend Unknown rangewide; unknown
but possibly declining in Kentucky due to the Comment recent increase in mountaintop removal surface
mining in the Cumberlands. In addition there seems
to be an ongoing general Desmognathus decline in northeastern
Kentucky for which additional investigation and documentation is needed. The mountain dusky salamander is known
historically from single sites in Carter County and McCreary County and has
not been seen at either of these locations
despite much searching over the past 20 years.
This species is not tracked by
Kentucky State Nature Preserves Commission. Habitat / Somewhat of a
habitat specialist in Kentucky; the best habitat includes moist Life History banks, streamheads, seeps, wet spots, and cool
moist forests at the highest elevations on Black
Mountain and other high peaks in the Cumberlands. Elsewhere in eastern
Kentucky the mountain dusky salamander is found in cool mucky seeps and wet
areas near waterfalls, or in close association with dripping rock faces and wet crevices along shaded
sandstone or shale cliffs (including coal mine entrances). Key Generally GOOD in the Cumberland Mountains, but
only FAIR elsewhere in Habitat eastern Kentucky; populations seem to be
declining in the northeast. The Daniel Boone
National Forest cliffline management policy will help maintain habitat for
populations that inhabit public lands in the Cliff Section of the Cumberland Plateau. Following Key

is widespread in southeastern U.S. (Conant and Collins Comment 1991). An
isolated population at the northwestern edge of the range occurs in the Western
Pennyroyal Karst Plain (Woods et al. 2002) of Kentucky and Tennessee including
portions of 8 western Kentucky counties (Redmond and Scott 1996, Kentucky

populations are apparently stable. In
our area, Kentucky State Comment Nature Preserves Commission monitoring data shows
recent records (1984- 2004) for all 8
known Kentucky counties. Barking
treefrogs breed rather sporadically in
seasonal and permanent ponds that are located primarily in open agricultural habitats, and several years may
pass in a given area between breeding events. It is quite difficult to track population
trends accurately within individual
colonies. Habitat / Adult barking
treefrogs are generally found only in agricultural areas in Life History Kentucky; most observations are for calling
males or tadpoles at breeding ponds. A few adults can sometimes be found crossing
wet roadways on rainy evenings. It is likely that most adults burrow into the
soil and remain underground for much
of the year, but this remains to be demonstrated. Radiotracking
studies are needed to determine the habitat requirements of the adults. Key Habitat condition overall is probably GOOD
within its limited range in Habitat Kentucky; the amount of cropland and pasture in
this area seems to be relatively stable
with little or no imminent threat from development or urban expansion. Following Key

population trend is unknown but is probably stable. The bird- Comment voiced treefrog is uncommon to rare in Kentucky
and may be declining; some populations (e.g., those
in Ballard County) have vanished since the 1960’s. Comprehensive survey
work is needed in the state. There are
recent (1984- 2004) records from 14
counties (Kentucky State Nature Preserve Commission 2004; J.R. MacGregor

counties in eastern Kentucky, primarily in the Cumberland, Kentucky, and
Licking River drainages; rare and local in the Little Sandy and Big Sandy systems
and apparently ranges no further north than Rowan, Elliott, Floyd, and Pike
counties (J.R. MacGregor Herpetology Maps 2004). S-Trend Decreasing S-Trend The Black Mountain
salamander has been documented since 1984 in at least 20 Comment counties in eastern Kentucky. Numbers are declining at numerous sites in northeastern
Kentucky in the Morehead/Laurel Creek Gorge area in Rowan and Elliott counties and
possibly in the Big South Fork area (McCreary County) as well. However, the species is regularly encountered
in suitable habitat in Red River Gorge and nearby,
in the Cave Hollow area (Lee County), and on Black Mountain (Harlan
County). This species is not tracked by
Kentucky State Nature Preserves
Commission. Habitat / The Black Mountain
salamander is more of a habitat specialist than most Life History Kentucky Desmognathus; it is largely a resident
of clear high-gradient mountain streams and is most
common in rocky headwater creeks in cool moist forested ravines on Black
Mountain and other high peaks in the Cumberlands. Elsewhere in eastern
Kentucky the Black Mountain salamander is primarily found in shaded
spring-fed streams. This species is
intolerant of silt; it is often associated with
small waterfalls and wet entrances to caves and abandoned coal mines. Key Habitat condition is generally GOOD in the
Cumberland Mountains, but only Habitat FAIR elsewhere in eastern Kentucky; populations
seem to be declining in the northeast. The Daniel Boone National Forest cliffline
management policy and buffer strips to
maintain forest cover along stream corridors will help maintain habitat for

has been found in 31 counties and occurs nearly throughout eastern Kentucky (J.R.
MacGregor Herpetology Maps 2004). S-Trend Decreasing S-Trend Population trends
seem to be variable in Kentucky. This
salamander appears to Comment be doing well at several sites in southeastern
Kentucky including Garrett (Floyd County), Black
Mountain (Harlan County), Pine Mountain above Bledsoe (Harlan
County), Limestone Cave (Whitley County), Pine Mountain Wildlife Management
Area (Letcher County), and Cumberland Gap National Historical Park (Bell
County) (all data from J.R. MacGregor 2000-2004 except Cumberland Gap
information from Third Rock 2003). In
some sections of northeastern
Kentucky, however, it has all but disappeared from many locations for no
apparent reason (J.R. MacGregor 2000-2004 data for Carter, Elliott, and Rowan
Co). The Cumberland Plateau salamander
has also declined rather dramatically
at several locations near Huntington, West Virginia where it was formerly
abundant (R. Highton, pers. comm. 2002).
Recent (1984-2004) records exist for 24
Kentucky counties (J.R. MacGregor data).
This species is not tracked by
Kentucky State Nature Preserves Commission. Habitat / The Cumberland
Plateau salamander is completely terrestrial.
Adults and Life History juveniles live in wooded areas; females deposit
small clusters of eggs in summer- fall in underground
retreats. As with other species of
Plethodon, all larval development takes
place within the egg and thus there is no free-living aquatic larval stage. Populations are highest on ridges and steep
slopes with mature forest cover, numerous
shaded rock outcrops, abundant leaf litter and/or woody debris on the surface, and (often) rocky or
gravelly soils (J.R. MacGregor). This species is
somewhat of a habitat specialist; it seems dependent to a large degree upon rock
crevices; many good populations occur in/along/near shaded clifflines, outcrops,
caves, rock shelters, and the entrances of abandoned coal mines. It also occurs in and under decaying logs, under
loose bark on dead trees, within split trees/logs, in old sawdust piles,
in cavities and crevices in living trees, and in
burrows on steep hillsides. CLASS AMPHIBIA Cumberland Plateau Salamander Plethodon kentucki Key Habitat condition is generally GOOD in many
areas in southeastern Kentucky, Habitat but perhaps only FAIR in an overall view if one
considers the unexplained population declines
that have taken place in some areas. Habitat
condition is generally good on most
public lands; Daniel Boone National Forest cliffline and cave management
policies will probably ensure that forest cover is maintained in some of the best
habitat in the Cliff Section and Rugged Eastern Area of the Cumberland Plateau. Following Key

isolated (Conant and Collins 1991). Recorded from 44 Kentucky counties; most
commonly found in eastern Kentucky but also
known from Jefferson-Bullitt (Caperton Swamp and Bernheim Forest), Edmonson-Hart
(Mammoth Cave area), Caldwell-Christian (Dripping Springs
Escarpment and Dawson Springs Seep Swamp), and Calloway (Blood

for at least 35 counties. The Jefferson
County colony at Caperton Swamp seems
to have disappeared during the construction of I-71 (Burt L. Monroe, Jr.,
now deceased, pers. comm. to J.R. MacGregor ca 1972), and the colony in
the Blood River area of Calloway County has never been relocated since its
original discovery. This species is not tracked by Kentucky State Nature
Preserves Commission. Habitat / Adult four-toed
salamanders live primarily in upland forests; good populations Life History also occur in wet woodlands along floodplains
and terraces border some large streams and rivers. Egg clusters are laid in late winter and
early spring and are usually attended by
females; nests are located near the edges of ponds, woodland pools, seeps,
or sluggish boggy headwater streams in which the larval development takes place after hatching. Most nests are hidden in mosses, but some are also found
in clumps of grasses or sedges, in and under chunks of decaying wood, or in
leaf litter. Most Kentucky sites are in
areas with acid soils. Natural vernal ponds on broad flat sandstone
ridges and wet areas located along old mine benches seem especially favored
as nesting areas. Key Habitat condition is generally GOOD overall. Habitat Following Key

treefrog and its close relative (Cope’s gray treefrog) form a Comment species complex that is widespread in eastern
North America (Conant and Collins 1991). Although the diploid species (Hyla
chrysoscelis) can be found throughout the state,
the range of the tetraploid species (Hyla versicolor) barely extends into Kentucky from the north. Breeding colonies are known from 3 counties in the Fort

treefrog populations appear to be stable both rangewide and in Comment Kentucky.
Although the diploid Cope’s gray treefrog (Hyla chrysoscelis) occurs throughout
the state, Hyla versicolor was not discovered in the Fort Knox area until the
mid-1980’s and the Ashland population was only discovered in 2000. No range expansions or contractions have been
noted in either population; this
species and Cope’s gray treefrog occur together and often use the same
breeding ponds at the same time of the year. Habitat / Both species of gray
treefrogs are more or less arboreal but can persist in Life History weedfields, shrubby areas, and thickets as well
as along tree-lined fencerows and in forests. Breeding sites include permanent and seasonal
ponds (and tire ruts) in either
forested or open habitats. Key Habitat condition is apparently GOOD; this

populations are increasing both in Kentucky and elsewhere, Comment especially in the northern portion of the range. In Kentucky, the green treefrog was known in the 1970’s
only from a few isolated colonies in counties bordering the
Mississippi River. Since that time, the
range has expanded throughout the
Jackson Purchase area and Land Between The Lakes National Recreation Area and
eastward along the Ohio River into Breckinridge County. Recent records (1984-2004)
exist for all counties that are known to harbor green treefrogs in Kentucky (J.R. MacGregor data, Kentucky
State Nature Preserve Commission 2004). Habitat / Green treefrogs
occur in and near cypress swamps and other wetland habitats Life History with abundant cover in the form of emergent
herbaceous vegetation, and seem to prefer areas that are more or less open. They may also require adjacent bottomland forests

mostly in the Jackson Purchase, Land
Between The Lakes National Recreation Area, and in the western
Mississippian Plateau. Also an old
University of Kentucky museum specimen
exists from Bagget’s Pond in McLean County (J.R. MacGregor
Herpetology Maps 2004). Mole salamanders
were introduced into ponds on the Dourson
Farm in Powell County and continue to persist there in low numbers (D. Dourson,
pers. comm.). More field survey work is
needed for the mole salamander, particularly in the
Western Coal Field and western Mississippian
Plateau where road cruising on rainy evenings may yield additional data. S-Trend Unknown S-Trend Mole salamander
populations that occur in bottomland hardwood forests in the Comment Jackson Purchase are probably declining due to
continuing habitat loss as a result of wetland
conversion and/or degradation. Populations
that breed in small ponds in
upland woods are likely faring better except in areas where development is
taking place (J.R. MacGregor data). This
species has been recorded since 1984
in 14 of 15 historic counties (exception: McLean County in the Western Coal Field). The mole salamander is no longer tracked by Kentucky State
Nature Preserves Commission. Habitat / Adults are fossorial;
some may construct their own burrows while others move Life History into small mammal tunnels, old root channels, and
similar underground retreats; most populations are
associated with native forest but at least one colony near Lamasco is located
within a loblolly pine plantation. Breeding
takes place in a variety of aquatic
situations including vernal pools, ponds, ditches, shallow swamps, and low
spots in swampy woodlands; most known breeding sites in Kentucky are located
within or close to forested areas. Some
populations that breed in permanent
ponds here are paedomorphic but mass transformations may occur when water
levels drop during prolonged dry periods (J.R. MacGregor data). The scattered series of isolated rainfall-driven
forested wetlands located in
shallow sinkholes on the karst plain in southern Logan, Todd, Christian, and

once plentiful in
southwestern Indiana in the 1970’s but has since declined to the point where it is
now listed as "Endangered" by IN.
Similar trends have been reported in other
parts of the range. The northern
crawfish frog seems to be doing well in some
portions of its range in Kentucky (i.e., at West Kentucky Wildlife Management

the Western Coal Field in the past 20 years.
These frogs are explosive
breeders and can be easily located only during the short but rather unpredictable early
breeding season; during some years the proper weather conditions never
come about and no breeding takes place. Much

characteristically spend most of their time underground in crayfish Life History burrows, sometimes emerging at night to feed. Most Kentucky colonies are associated with
prairie soils (W. D. Hendricks, pers. comm.) and occur primarily in pastures
and other grassland habitats. Breeding
ponds can be either seasonal or permanent and are primarily
located in agricultural landscapes. Our general lack of knowledge concerning the
habitat requirements of adult northern crawfish frogs outside the breeding season
warrants the gathering of additional data by the use of
radiotelemetry on lands managed by state and/or federal agencies (i.e. West
Kentucky Wildlife Management Area or Clarks River National Wildlife
Refuge). CLASS AMPHIBIA Northern Crawfish Frog Rana areolata

frog is a widely distributed species in the northern, Comment midwestern, and northeastern U.S. The range extends southward through the Bluegrass Region of
Kentucky (Conant and Collins 1991). It
is known historically from at
least 22 Kentucky counties extending westward from Mason County to
Carroll County along the Ohio River and southward into Mercer, Jessamine, and
Madison counties (Kentucky State Nature Preserve Commission 2004, J.R.
MacGregor Herpetology Maps 2004). S-Trend Decreasing S-Trend Northern leopard
frog populations have declined dramatically throughout large Comment sections of the range, but the species does seem
to be holding its own at least in some areas. The available data indicates that northern
leopard frogs are declining here and
have become scarce or extirpated in many Bluegrass counties in Kentucky. Although new sites are being found with some
degree of regularity, most of
these have not been monitored long enough to generate any long-term data. Recent records (1984-2004) exist for northern
leopard frogs in only 10 Kentucky
counties; all others (12 counties) are considered historical. The northern leopard
frog was a common species in rural Jessamine County through most of the 1970’s
but disappeared abruptly in 1980 (J.R. MacGregor data); it was also
common during the 1960’s in Mason County, when a number of specimens were
collected and deposited at the University of Kentucky, but many years have passed
since a live individual has been seen there as well. Habitat / Adult northern
leopard frogs are most often found in low meadows, grassy Life History fields, and pastures bordering ponds, swampy
areas, and sluggish streams. At least some tree
cover is usually present nearby, but the frogs seem to do most of their insect
hunting in the open areas. Typical
breeding sites are seasonal or permanent ponds
located in pastures or old fields; submerged and emergent vegetation are
usually present in these ponds. Swamps
and oxbows serve as excellent breeding
habitat but these are scarce in the highly modified landscapes of the Bluegrass. On the Kentucky River Wildlife Management
Area in Owen and Henry counties, northern
leopard frogs have been documented in 2003 and 2004 as calling from
several areas of recent origin (2 moist soil units and a shallow flooded
field behind a beaver dam). Tadpoles
were present in the moist soil units later in the season but not at the
beaver dam where fish predation is likely posing a
problem. CLASS AMPHIBIA Northern Leopard Frog Rana pipiens Key Habitat condition overall is UNKNOWN. However, many ponds that appear Habitat suitable for use as breeding sites are

throughout northeastern U.S. and adjacent Canada, barely extending Comment into northern Kentucky (Conant and Collins 1991). The northern redback salamander is known
only from a limited area of northern Kentucky in portions of Boone, Kenton, and
Owen counties; there is also a single specimen from Fleming County in
the University of Louisville collection (Kentucky Herpetology Database
2004, Kentucky State Nature Preserves Commission Database 2004, J.R. MacGregor
Herpetology Maps 2004). S-Trend Decreasing S-Trend Northern redback
salamanders tend to be quite abundant in good habitat. Comment Populations appear to be doing well along Eagle
Creek in Owen County and at a few recently visited sites in Boone and Kenton
counties (J.R. MacGregor field data 2000-2004), but
no organized monitoring has been done to check on the condition of most
populations. Urban and industrial
development continues to impact potential
habitat at a rapid rate in northern Kentucky, and this species is almost certainly on the decline in that region
of the state. Efforts to locate additional specimens
in Fleming County have thus far been unsuccessful (J.R. MacGregor data). Habitat / The northern redback
salamander is completely terrestrial. Adults
and juveniles Life History live in wooded areas; females deposit small
clusters of eggs in early summer in underground retreats
or within decaying stumps and logs. Larval
development takes place within
the egg and thus there is no free-living aquatic larval stage. Populations are
highest on ridges and steep slopes with mature forest cover, abundant leaf litter
and/or woody debris on the surface, and (often) rocky or gravelly soils (J.R.
MacGregor). These salamanders appear to
be able to persist in low numbers in developed areas as long as
some forest cover, adequate access to
underground winter/dry weather retreats, and leaf litter or other surface debris
remain available. Key Habitat condition at the present time is only
FAIR, and the prognosis for the Habitat foreseeable future is generally POOR. Following Key

counties extending
throughout all of southern and western
Kentucky (to the south and west of
the Bluegrass) with a northeastern extension through the eastern Knobs into
Carter, Lewis, and Greenup counties; the species is generally absent
from the rugged terrain of eastern Kentucky and from the Bluegrass Region (J.R.

intermediate between this form and the northern leopard frog - and appear to
be in decline. The southern leopard frog
is considered to be a common species here and records are not
tracked by Kentucky State Nature Preserves Commission. Habitat / Adult southern
leopard frogs are most often found in meadows, grassy fields, Life History pastures, and other open habitats near ponds, swamps,
and streams and in edge habitats bordering
bottomland forests. Like northern
leopard frogs, these frogs seem to do most of
their insect hunting in the open areas. Typical
breeding sites are seasonal
or permanent ponds, road ruts, and shallow swamps and other wetlands
located in or near open areas. Submerged
and emergent vegetation will
usually be present in these ponds. Key Habitat condition overall is GOOD, except for
the disappearing population in Habitat the northeastern part of the state where it is
POOR.
