The objective of this manual is to train volunteers in the process of identifying vernal pool habitat so that as many of these pools as possible can be certified by the Massachusetts Natural Heritage and Endangered Species Program. Vernal pools are a kind of temporary pond in which salamanders and other animals breed. The pools are unique biological habitats and are not easily replaced. Due to a lack of funds and staff, volunteer citizens are needed to gather the necessary documentation for certification. This manual is written for amateur naturalists, biologists, botanists, and novices to the world of nature. Nine easy steps for certification are discussed: understanding vernal pools; understanding certification, protection, and the law; finding the pool; assessing the pool; documenting your findings; mapping the pool; putting it all together; following up; and practicing stewardship. Includes 35 references. (DDR)
