For many of us, our first hands-on experience with nature
was with a reptile or amphibian; perhaps observing a garter snake slither across the driveway or catching a
Fowler’s toad as it hopped on the lawn. People
who have had a positive experience with wildlife during their childhood are more
likely to support nature conservation as adults. The authors of this field guide were such children, and
still maintain a youthful awe at the amazing beauty and diversity of these
magnificent creatures.
So how can we protect and conserve native reptiles and
amphibians while maintaining the educational and economic benefits derived from
them? First, it is better to let wild animals remain wild. However, the
educational value of studying and learning to care for such animals can
ultimately result in on-the-ground conservation, so it is something we do not
want to completely discourage. Putting the well being of the animals and their
habitats first always, we can study wild reptiles and amphibians in an ethical
manner; we have compiled a number of acceptable capture and handling techniques
which should be followed. If you are considering purchasing tadpoles or frogs
and releasing them into the wild, then please read
Problems with Buying Frogs and Tadpoles for Wild Release.
If possible, work with someone who has experience safely
and ethically handling reptiles and amphibians. The most common technique used
to find many species, particularly salamanders, lizards, and small snakes, is by
looking under and within rotting logs, peeling bark, rocks, and other debris. Please be sure to return the rock or log back to it’s original position
to reduce alteration to the animals micro-habitat. Do not place the animal
under its cover then put the rock or log on it. Released animals should be
placed next to the rock or log after it has been returned to its
original position to avoid injuring the released animal. The animal will find
its own way back “home”.
Of course care should also be taken for your own safety
when attempting to capture or handle any animal. Be aware of who you might meet
in a given habitat before you go looking. Venomous snakes also reside under
rocks, logs and debris so it is wise to use a “snake hook” or rake when
lifting rocks and logs to avoid being bitten, and always first lift the
side farthest from you so your lower extremities are not exposed to danger.
Handling the animals also requires care. Amphibian’s
mucus-covered skin performs many functions and is easily damaged. These
functions include: protection against abrasions and pathogens; as a respiratory
membrane (they absorb oxygen through it); body water regulation; aid in control
of body temperature; protection against predators through poisons in the skin
(Stebbins and Cohen 1995). The safety tips below are intended to protect both
the handler and the animal.

Legal Issues
There are some legal issues which must be considered. In
1993, regulations were passed in Maryland called “Reptile and Amphibian
Possession and Permits” (COMAR 08.03.11). These clearly defined what species
could be collected from the wild, set possession limits for those species that
could be collected with a permit, stated which species may be collected without
a permit, and other allowed activities, such as captive breeding, which requires
a permit. These regulations are also important for what they state cannot be
done, such as commercial trade in “wild” caught animals. They also identify
illegal methods of taking an animal from the wild. For instance, did you know
it is illegal to kill a snake? Other Maryland laws and regulations that you
should be aware of include:
- a prohibition on importation of venomous snakes,
alligators, and crocodiles as pets (Article 10-621);
- seasons and size limits for the harvest of
diamond-backed terrapins, and complete protection of their nests (COMAR
08.02.01);
- prohibited methods of take for snapping turtles (COMAR
08.02.01);
- limitations on the sale of turtles (COMAR 10.06.02);
- and designation and protection of state endangered
species (Article 10-2A-01 and COMAR 08.03.01).
Scientists use a myriad of surveying techniques for
reptiles and amphibians. The simplest may be using a dip-net to collect frogs
from ponds. Something more complicated may involve building a long drift fence
with various funnel, pit-fall and other traps attached to capture most species
occurring in an area. However, even scientists are required to obtain a
scientific collecting permit from the state in order to use these
techniques. Simple observation, or what we call random visual surveys,
are often a great way to learn the herpetofauna of an area and witness
interesting behaviors. So whatever your interests are, be safe, be ethical, and
be legal. Happy herpin’!
