Vernal Pools are typically ephemeral surface waters that flood in winter and typically dry up in summer. By definition in Maine, New Hampshire, Massachusetts, and most other northeastern states, vernal pools contain one or more biological indicators, have ice-free water for at least 60 days on an average year, and do not regularly support fish. The bio-indicators for vernal pools include any of the mole salamanders (i.e. spotted, Jefferson’s, blue-spotted, or marbled), wood frog, and/or fairy shrimp. In addition, they typically host a variety of macro-invertebrate organisms besides fairy shrimp that provide food for the breeding amphibians.

Vernal pools are incredibly important on the landscape as they provide temporary habitat for migratory wildlife such as waterfowl, turtles, and other amphibians, as well as food chain support for larger wildlife. They also provide a source of fresh water for deer and other large game, and contribute to the diversity of plants, algae, mushrooms, and aquatic micro-organisms. Normally they occur in otherwise dry landscapes such as at watershed divides, low terraces, and floodplains.

The Tin Mountain zoom seminar will introduce participants to ecology and conservation of vernal pools through a slide lecture program. We will talk about the physical, chemical, and biological aspects of vernal pools, as well as the conservation effort at the GMCG headquarters that resulted in the creation and protection of a significant vernal pool. We will also talk about vernal pool buffers, the road crossing guard programs in the state, and forestry BMPs as they relate to these depressional landscape features.
