Project Summary (8/2008):
Vernal pools are small seasonal wetlands that fill with spring rains and generally dry down by the summer’s end. They are critical breeding habitat for species adapted to life in temporary waters, including fairy shrimp, spotted and blue spotted salamanders, and wood frogs, and provide food to upland wildlife as well. Because of their small size and ephemeral nature, vernal pools are often overlooked by regulatory agencies and are rapidly being filled for development. As a result, vernal pools are among the most threatened wetland type in the northeastern US. While a number of northeastern states have been proactive in their attempt to maintain the functional value of vernal pools, the Maine legislature was the first to recognize a subset of vernal pools (Significant Vernal Pools) as Significant Wildlife Habitat, a status that allows both the pool to be protected and a portion of the adjacent upland habitat as well. As of September 2007, pools that meet certain biological criteria (based on egg mass abundance of key species and presence of listed species) are deemed to provide Significant Wildlife Habitat and as such are regulated under the Maine Natural Resource Protection Act. The state is unable to pre-map these resources, so it is incumbent upon private landowners to determine if they harbor Significant Vernal Pools prior to developing their land.
The most efficient and cost-effective way to ensure the long-term viability of vernal pool resources is through local planning initiatives that move management from a reactive crisis mode to a proactive planning mode. The intention of this project is to work with citizenry and town officials in Orono, Maine, to inventory and assess vernal pool resources using trained citizen scientists, and to encourage the Town to incorporate vernal pools into a natural resource database for conservation planning purposes. Since we started this project, six additional towns, influenced by the State legislation, have contacted us for help in proactively mapping their vernal pools. Given our limited resources, it became clear that our project should expand its purpose to include development of a Maine Municipal Guide to Vernal Pool Conservation designed to provide pertinent information on vernal pool ecology and the process of using citizen scientists to map and assess pools. This Guide will also outline options for using a vernal pool data layer in conjunction with other spatial data layers to initiate conversations about natural resource planning. Feedback from the towns (Scarborough, Orono, Brunswick, Wayne) that are currently working with us will provide guidance in developing this document.
