Ecology and Vulnerability Brook Trout

Map displays likely Brook Trout habitat in blue (coldwater fisheries resources streams).

Also displayed are streams where Brook Trout have been observed (by Mass DFW personnel) shown in orange.

The "Probability of Occurance" map displays current distribution of Brook Trout. Streams in blue are more likely to be inhabited by Brook Trout based on environmental conditions, while streams in yellow are less likely to have Brook Trout. Stream characteristics that help predict whether Brook Trout can be found in each stream include stream size, average air temperature, nearby forest cover, and soil characteristics. Estimates are from the USGS Conte Anadromous Fish Research Center, based on field surveys from Massachusetts DFW and agencies of nearby states CT, NH, VT, and NY.
