Vernal Pools

Vernal pools are temporary ponds that form in the spring as melting snow and precipitation fill shallow depressions in the forest floor. These sites are the primary breeding environments for frogs, newts, salamanders, and other amphibians. Usually on a rainy night in early spring thousands of amphibians will migrate into these shallow pools for their annual mating “congresses.” The development of the amphibian larvae to a stage of being self-sufficient in a terrestrial environment is then a race with the evaporation and drainage of the pool as spring commences. By summer these pools are usually only recognizable by their shallow micro-topography and moist soils supporting tree species like white ash and red maple.
