Vernal Pool Pop-Up Field Trip: Frederick County

 , , , , , ,

Animals Field Experiences Open to the Public

It’s challenging to predict when frogs and salamanders will migrate from their wintering spot in the forest to a vernal pool to reproduce. With the weather warming over the weekend, this Monday looks like the best chance for amphibian activity.
Vernal pools are shallow depressions in the ground that usually fill with water for only part of the year. Melting snow and spring rains fill the holes with water, creating an essential breeding habitat for specific species of frogs and salamanders. These amphibians leave their winter hibernation in the woodlands, find a vernal pool, mate, and lay their eggs in the water, leaving their young to hatch and grow in the pool. As the seasonal rains dry up, so do the vernal pools, sending the new generation of amphibians into the forest until their next breeding cycle.

Amphibians such as wood frogs, spring peepers, toads, spotted salamanders, and other woodland salamanders are popular residents in our local vernal pools. Their egg masses suspended in the water may be visible, too, with the baby salamander efts or tiniest tadpoles writhing inside. With 700 species in the Northeast relying on vernal pools, the loss of pools due to development is of major concern, and preserving the few that remain is critical. With fewer pools, we see a decrease in biodiversity and a decline in the amount of food available for other animals that live in these areas, such as small carnivores.
