Species Distribution in Massachusetts


Federal Rank: None

Massachusetts State Rank: Threatened

Habitat Description

Relatively mature deciduous and mixed deciduous-coniferous forests and woodlands, with elevation and forest types varying between populations. Breeding habitats are variable, consisting of vernal pools, woodland ponds, shrub swamps and forested swamps differing markedly in their surface areas, depths, bottom substrates and/or densities and composition of vegetation. Throughout their habitats there are three consistent characteristics: they are almost always fishless, occur within or adjacent to forests, and hold water continuously during a minimum period of January-May.

Threats to Survival

Habitat loss, habitat degradation, susceptibility to pesticides and road fatalities.

Actions Recommended to Ensure Survival

Develop or maintain mature forest conditions within at least 1,000-ft radii around confirmed and potential breeding wetlands to minimize forest loss/fragmentation, road traffic, soil compaction and introduction of invasive vegetation. Area between mature upland forests should be maximized to maintain broad dispersal corridors.
