Vernal Pool Studies

Vernal pools, also known as ephemeral pools, are temporary bodies of water that can be found in
spring due to autumn rains and winter snow-melt.  Vernal pools dry completely by the middle or
end of summer each year, or at least every few years. Occasional drying prevents fish from
establishing permanent populations. Many amphibian and invertebrate species rely on breeding
habitat that is free of fish predators.

Some vernal pools are protected in Massachusetts under the Wetlands Protection Act regulations, as
well as several other federal and state regulations, and local bylaws.  Many others are not protected
and are found on public and private properties of Masschusetts. Through the Natural Heritage &
Endangered Species Program offers a program to "certify" vernal pools based on the amphibian
species that utilize the pool.  This process relies on volunteers to identify vernal pools, and to collect
and submit documentation.  The documentation information can be found at NHESP
 "Guidelines for the Certification of Vernal Pool Habitat"

At Mount Grace, we focus student field study on the collection of amphibians, macroinvertebrates,
pool characteristics, and some water chemistry.  Since 2009 Mount Grace has facilitated classroom
lessons, field work, and follow-up documentation work to certify 17 vernal pools in the region.  The
process of gathering information for certification is an excellent way for people to learn about vernal
pools and the animals that use them, and to become involved in the protection of natural resources in Massachusetts.
