Brook trout current probability of occurrence

November 3, 2015/in Aquatic, Supporting Data /by m.mallek

Brook trout current probability of occurrence is based on a model developed by Ben Letcher and associates at the USGS Conte Anadromous Fish Lab. It is an index applied to headwater creeks within the watershed, and is analogous to the landscape capability index used for the terrestrial wildlife species in that it represents current habitat suitability. It is applied at the scale of small catchments associated with a given stream segment, rather than 30m cells as used for terrestrial wildlife. This index is used to generate the aquatic core area selection index.

About Connect the Connecticut

What can we do today to ensure a sustainable future for the Connecticut River watershed? Connect the Connecticut is a collaborative effort to identify the best places to start: a network of priority lands and waters that can support wildlife and natural systems, with multiple pathways for migration, restoration, development, and conservation.

Connect the Connecticut is supported by The North Atlantic Landscape Conservation Cooperative, an applied science and management partnership that builds upon a long history of conservation in the region to unite stakeholders around common goals for sustaining natural and cultural resources, and to develop tools and strategies to achieve those goals in the face of threats and uncertainty.
