Vernal pools, also known as seasonal forest ponds or temporary woodland pools, are seasonal water bodies that support unique communities of amphibians, aquatic insects, and other fauna. They contribute markedly to local and regional biodiversity and in some cases support populations of rare species. The community composition of vernal pools varies across and within pools with seasonal site hydrology and other factors. Due to their small size and seasonal flooding vernal pools represent a challenge for conservation.
This research represents a multi-decadal study of pools across Massachusetts. Focus in 2026 is on continuing to verify identifications of specimens, updating labels, and preparing collection for archival museum storage. A side project involves collaborating with Sally Farrow, of Massachusetts Audubon's Drumlin Farm Sanctuary, on a comparison of results of educational-program sampling of vernal pools at the sanctuary with in-deptn inventory sampling I carried out in the same pools in the 1990s.
