The Mattapoisett Land Trust is offering its annual vernal pools workshop and field trip this April.

Vernal pools are a breeding habitat for amphibians and invertebrates such as wood frogs, spotted and blue-spotted salamanders, and fairy shrimp.

The workshop will begin with a presentation at the Mattapoisett Library on Wednesday, April 3, from 7 p.m. to 8 p.m. Wetland scientist Elizabeth Leidhold will describe with exhibits and slides some of the animals that rely on vernal pools for survival.

On Saturday, April 6, at 9 a.m., she will lead the investigation of one of the MLT's vernal pools. The site will be determined by the weather conditions. This event offers parents and children the opportunity to learn together about the wetlands of Mattapoisett and how they can help protect them for future generations.

The state forms for certifying vernal pools will also be provided to all participants so that they can learn how to properly complete the forms of the Commonwealth's Natural Heritage and Endangered Species Program.

Both events are free and open to all, including residents of other towns. Attendance at the presentation is not required for participation in the field visit on Saturday. Anyone interested in visiting a vernal pool should meet at Dunseith Gardens (the Seahorse property) on Saturday morning at 8:45 a.m. For more information call 508-317-5932 or email info@mattlandtrust.org.
