Maryland Amphibian &
Reptile Atlas
A Joint Project of The Natural History Society of Maryland, Inc.
& the Maryland Department of Natural Resources
July 2013 Newsletter
Hello!
Despite the heat, we have still had some really exciting finds this summer. Eastern Narrowmouthed Toads have been reported, with photos, from St. Mary’s County. A Kemp’s Ridley Sea
Turtle was reported from Dorchester County waters. We have also had a Mole Kingnskae
reported from Prince George’s County. An Eastern Six-lined Racerunner was found in Anne
Arundel County. There have also been Smooth Earthsnake, Queensnake, and Eastern
Kingsnake sightings. Gray, Cope’s Gray, and Green treefrogs, Northern Green Frogs, and
American Bullfrogs have been calling. Various salamander reports have also been shared. All in
all, summer has been pretty good to us, so far.
The error message at the online submission site for incidental data,
http://marylandnaturalist.org/submit-observation/, has been resolved. Please let us know if
you experience any difficulties or errors when using this site.
Just as a note, 2014 has been designated “Year of the Salamander” by PARC (Partners in
Amphibian and Reptile Conservation). To learn more please see the following website.
http://www.parcplace.org/news-a-events/2014-year-of-the-salamander.html
A presentation about the Maryland Amphibian and Reptile Atlas was given, by Heather
Cunningham, at the International Congress for Conservation Biology. The meeting was held in
Baltimore July 21-25. The presentation was given during a session on public participation in
science.
An additional feature has been added to the ‘Project Status’ link at the MARA database,
https://webapps02.dnr.state.md.us/mara/default.aspx?strSelection=SystemStats. Specifically,
there is a new report that lists the sightings entered by county. It is found in the county section
of the report table and gives the most recently entered sightings at the top. This was developed
to make it easier for coordinators and atlasers to update any personalized spreadsheets they may
have created for targeted surveys or other reasons. It lists the observer and sighting ID of
recent sightings.
Thanks to everyone who contributed to this month’s newsletter. Be sure to contribute news,
stories, or photos to upcoming newsletter.
Happy Herping!

Atlasing for herps in the Carolinas
By Glenn Therres, MARA Co-chair, Queen Anne’s County Coordinator,
and Talbot County Co-coordinator
During the last week of June, my wife and I went to North Carolina for a week to visit our
newly-wed daughter and her husband. They live in Raeford, which is on the edge of the
coastal plain of North Carolina close to the Piedmont. Much of the area is dominated by longleaf pine forests, hardwood swamps, farm fields, and the suburbs of Fayetteville.
Since the Carolinas have many more species of reptiles and amphibians than Maryland, I
decided to look for some while I was in the area. Within a half hour after unloading the
luggage from the family minivan, I caught a Little Brown Skink (Scincella lateralis) in my
daughter’s backyard. Nice start to the vacation! That evening I heard Cope’s Gray Treefrogs
(Hyla chrysoscelis) and one Squirrel Treefrog (H. squirella) calling in the neighborhood.
I was aware of the Carolina Herp Atlas project, so I decided to herp with a purpose on my
vacation. That purpose was to add records to their atlas project. The Carolina Herp Atlas
project started in 2007. The primary objective of the atlas is to provide detailed data on the
distribution of reptiles and amphibians of both North and South Carolina. Instead of being a
grid-based atlas like MARA, the Carolina Herp Atlas maps records at the county level. Instead
of the project recruiting an army of volunteers to actively search for herp records like MARA,
the Carolina Herp Atlas depends mostly on volunteers submitting incidental records when they
find a reptile or amphibian. No verification of any species is required, though they do provide
the opportunity to submit a photo of one’s observation.
The Carolina Herp Atlas has a website
(http://www.carolinaherpatlas.org) where
volunteers register to submit records and to view
results of the project. I was the 1,488th observer
to register. Submitting a record is fairly simple.
After clicking on “Submit Record” the data entry
screen appears. The observer selects the state
and county in which the herp record occurred, as
well as the group (eg., snake or lizard) and
scientific name of the species. Then one enters
the date and time of the observation. Location
of the observation is typed in along with the latlong coordinates. A photo can be added if the
observer took one.

Like MARA’s real-time database, as soon as a record is submitted it populates the map if it is a
new record. If it is a new record, the county in which it was found is shaded dark pink on the
map.
During my vacation in North Carolina, I added eleven new county records and 25 total
records to the Carolina Herp Atlas. Some of the new records were Cope’s Gray Treefrog and
Squirrel Treefrog in Hoke County, Green Anole (Anolis carolinensis) in Cumberland County,
and Eastern Wormsnake (Carphophis amoenus) and Banded Watersnake (Nerodia fasciata) in
Harnett County. The watersnake was huge and basking on a large boulder along the shore of
the Cape Fear River. At first, I thought it might be a Cottonmouth (Agkistrodon piscivorus). But
upon close inspection of its eye through binoculars, I could see it had a round pupil.
The last morning of my trip, my daughter and I explored the creek and floodplain behind her
house. She found a male skink basking on the side of a tree. I took a few pictures of its head
to look at the scales on the upper lip and in front of the ear hole. That ruled out Broadheaded Skink (Plestiodon laticeps). However, the scales on the head of both the Common Fivelined Skink (P. fasciatus) and Southeastern Five-lined Skink (P. inspectatus) look the same. The
two distinquishing characteristics to separate the species were not evident on my pictures
(namely the scales on the underside of the tail and the rows on which the stripes of a female
or juvenile occur). Neither species has been reported from Hoke County yet and I could not
identify this skink. Guess I will have to go back and visit another time.
A little ways down the creek from my daughter’s backyard we found a water snake at the edge
of the shoreline. I passed it off as a Banded Watersnake, but took some pictures of it for the
atlas. When I got back to Maryland and loaded the pictures on my computer, I noticed the
pupil was a slit instead of rounded. This Banded Watersnake turned out to be a
Cottonmouth. Cool. Good thing I took those pictures. That Cottonmouth was one of the
new county records I added to the Carolina Herp Atlas.
That snake brought the total records
submitted to the Carolina Herp Atlas to
21,359. That same day, over 24,000
records had already been submitted to the
Maryland Amphibian and Reptile Atlas.
Remember, our statewide atlas started
three years after the project in North and
South Carolinas. How did we get ahead
of an atlas in two states with lots more
species?

We are good, really good!!! That, and we designed our herp atlas based on active searching by
county coordinators and their volunteers. We don’t rely on incidental reporting; we actively
seek out and record amphibians and reptiles in every one of our 1,300 survey blocks. Of
course, we take incidental records as well. Setting minimum coverage goals of 10 species per
block and 25 species per quad is a major factor as well. But the key to MARA’s success is our
army of volunteers actively flipping logs, cruising roads, listening to frog calls, looking at
turtles through binoculars, etc. The Carolina Herp Atlas (and those in other states) cannot
hold a candle to us. We are kicking butt!!!

Closing gaps
Since it is a little hot out for the terrestrial salamanders across much of the state, we can focus
our attention on those that favor stream habitats. Northern Dusky Salamander, Northern Red
Salamander, and Northern Two-lined Salamander are expected to occur over a large portion of
the state. Look for these salamanders near or in streams. Look under rocks, logs, and course
woody debris along the margins of small streams or seeps within forests. Breeding occurs in the
fall for Northern Red Salamanders and Northern Dusky Salamanders; thus, an increase in activity
may be observed. The maps are shown at the block level.
Northern Dusky Salamanders are variable in
color and pattern. Generally, they are dark
brown with a dark dorsal stipe and a cream
belly with gray or brown flecks. They also
have a dark line that extends from the eye to
the mouth.

Northern Red Salamander
Northern Two-lined Salamanders
are small, yellowish salamanders.
Individuals will have a black or
brown line running from each eye
to the tail that border a light middorsal stripe. The light mid-dorsal
stripe is often sprinkled with black
spots. Some older individuals may
appear very dark in color.

Northern Dusky Salamander
Northern Red Salamanders are relatively
large, stout salamanders. As the name
implies, they are red to reddish brown
with irregular, rounded black dorsal spots.
Their color will often darken with age.
Their eye color is yellow.

species that favor spring, stream, or seep
habitats can still be found. We should see
surface activity of some terrestrial species
resume in a few months.

cruising on rainy evenings and nights can still
net a lot of good data. Frogs and toads will
still frequent wet roads.

Miss Dixie’s Herp Corner
MARA
A place for random questions, thoughts, and facts about
amphibians and reptiles.
What is in a name?
Recently, I came across a website that shared the meanings of Latin, and some Greek, scientific
names of amphibian and reptile species. I thought I would share a few for some of Maryland’s
salamanders. Some are pretty interesting. The meanings reference the species name, not the
genus name. Check out more here, http://ebeltz.net/herps/etymain.html.
•Ambystoma jeffersonianum, Jefferson Salamander, name honors Jefferson College, PA.
•Ambystoma tigrinum, Eastern Tiger Salamander, name references coloration of some
salamanders.
•Plethodon cinereus , Eastern Redbacked Salamander, cinereus- ash colored, name references dorsal
color of lead backed phase.
•Plethodon glutinosus, Northern Slimy Salamander, glutinosus-full of glue, references sticky skin.
[*Incidentally, the meaning of the Greek genus name, Plethodon, is pretty interesting too. Plethore
means “fullness or full of ” and odon means “teeth.” The refers to the number of paravomerine
and vomerine teeth. So basically, a salamander full of teeth and glue—good thing these
salamanders are not any bigger!]
•Desmognathus fuscus , Northern Dusky Salamander, fuscus- dark or swarthy, names references
color.
•Gyrinophilus porphyriticus , Northern Spring Salamander, Greek porphyros means reddish-brown,
purple while the Latin icus calls attention to the color, name references color.
•Eurycea longicauda , Long-tailed Salamander, longus means long and cauda means tail, name
references that tail length is usually greater than snout vent length in these salamanders.
•Hemidactylium scutatum , Four-toed Salamander, scutatus means armed with a shield, name
references how the costal grooves appear covered with shield-like plates.
[Speaking of salamanders, check out the following account of the courting behavior of the Long-tailed
Salamander in Maryland.]

MARA Steering Committee Meeting Notes
The MARA Steering Committee met Thursday, June 13th at the Department of Natural
Resources Headquarters in Annapolis. Those in attendance included Glenn Therres, Lynn
Davidson, Nate Nazdrowicz, David Smith, and Heather Cunningham.
The meeting began with a brief update from the Statewide Coordinator. The website has been
updated with links to the project database and project results.
The next item of discussion was database and verification updates.
The committee discussed sending a follow-up email to county coordinators to explain that
coordinators are not responsible for manually combing through the database to look for reports
submitted of which they are unaware.
The committee also discussed items for the newsletter.
The next MARA Steering Committee meeting will be held Thursday, July 18th at 6:00pm at the
DNR headquarters in Annapolis.
