Vernal Pools

At winter's end, woodland hollows and low areas flood, creating temporary isolated pools. The resulting vernal pools fill with melting snow, spring rain, runoff, and rising groundwater.

These pools provide critical breeding habitat for several amphibian and invertebrate species with life cycles that have adapted to these rich, temporary phenomena.

Certification is one of the best ways to protect vernal pools, which are extremely vulnerable to development. They are often overlooked when wetlands are identified on development sites because in many months these areas are dry and resemble the surrounding woodland. Learn More >

The best time to see a vernal pool is spring. Watch for tiny tadpoles swimming about, camouflaged masses of frog or salamander eggs, or delicate fairy shrimp safely sheltered under submerged leaves. You'll catch a glimpse of a magical and critical part of the seasonal cycles of New England, and come away with a better understanding of why we need to protect the nature of Massachusetts.

Many of Mass Audubon wildlife sanctuaries are home to vernal pools.
