The Early Spring Amphibians and Reptiles
Mid-March to mid-April finds many of the early spring amphibians
and a few reptiles out and about in New Hampshire. Activity is
especially rich around vernal pools (also known as spring ponds,
ephemeral ponds, and other names). These ecological communities
are rich in species diversity and several frogs and salamanders
require or regularly use these areas for breeding.
The MOLE SALAMANDERS, including the spotted and Jefferson/blue-spotted
complex are very early migrants and breeders. The Jeff/blue-spot
types may migrate under the cover of darkness on humid nights in
early to mid-March even without rain! Typically, they and the spotted
salamanders emerge from their underground wintering sites, march
down woodland slopes and reach their vernal pools to court and
lay eggs.
A NOTE ON THE JEFFERSON AND BLUE-SPOTTED SALAMANDERS: Your field
guide may indicate two or more separate species (Jefferson, blue-spotted,
Tremblay's, and/or silvery salamanders). A great deal of confusion,
analysis, and rethinking is going on with this impressive variation
of forms and the current trend is to lump all the variations into
the one name: the Jefferson/blue-spot complex. Until further notice,
and for the purpose of the New Hampshire RAARP, we are not going
to attempt to split populations of this/these salamanders. If you
find a big, robust, mole salamander that doesn't have yellow spots
on it this season, simply call it a member of the Jeff/blue-spot
complex.
WOOD FROGS AND SPRING PEEPERS are also out in force in March
and April. The wood frogs are abrupt breeders, appearing in vernal
pools with the mole salamanders mentioned above. They remain in
the ponds just a few days and then return quickly to their woodland
haunts. Their quack-like advertisement calls do not carry well,
but they will vocalize day and night at the height of their breeding
season. Peepers are tiny mites that are difficult to find at best.
Triangulation works best, with two or three people pointing their
flashlights to where each thinks a single peeper might be. Begin
your search where two or more beams cross.
As for early REPTILES, your best chances are to find the GARTER
SNAKE and the SPOTTED TURTLE. Garter snakes will appear during
sunny, warm days near houses (woodpiles) or on the forest floor
(in sunny spots). Spotted turtles are in flooded meadows and swamps
where skunk cabbage, alder shrubs, and tussock sedges are common.
Many individuals are skittish, so scan with your binoculars for
their heads sticking above water or for basking adults hauled out
on shore or a log.
Other species may be found in March and April, especially if
there is an early warming period.
What about larvae?
In a nutshell, don't worry about them. Many
frog and salamander larvae are difficult to identify even in a
laboratory. Photographs are just not acceptable though we would
be glad to look at any you have. Feel free to report and describe
any larvae you can confidently identify. Refer to the
Keys to Larval Salamanders and Larval Frogs.
