Description:

This dataset is a component of a complete package of products from the Connect the Connecticut project. Connect the Connecticut is a collaborative effort to identify shared priorities for conserving the Connecticut River Watershed for future generations, considering the value of fish and wildlife species and the natural ecosystems they inhabit.

This dataset depicts the potential capability of the landscape throughout the CT River Watershed to provide habitat for American black bear based on environmental conditions existing in approximately 2010. All locations are scored on a scale from 0 to 1, with a value of 0 indicating no capacity to support the species and 1 indicating optimal conditions for the species.This species dataset is one of a larger set of results developed by the Designing Sustainable Landscapesproject led by Professor Kevin McGarigal of UMass Amherst. The species datasets developed under the project include the following:

1. Landscape capability datasets for a set of species intended to represent a broader set of wildlife species, and associated ecosystems, that collectively encompass a majority of the terrestrial, wetland, and coastal ecosystems of the Northeast. For each species, the datasets include projections of future development, climate, and forest change, for the years 2030 and 2080.

2. Datasets for each species that compare 2010 results to future scenarios for 2030 and 2080. These include areas where the species could most likely be expected to persist, areas where it might be able to colonize, and areas where the species might experience a loss of suitable habitat.

More information and detailed documentation for the Designing Sustainable Landscapes project, which includes many additional datasets besides the species datasets, is available at http://www.umass.edu/landeco/research/dsl/dsl.html

The 2010 Northeast Landscape Capability Dataset for this species represents a habitat capability model developed using a spatially explicit, GIS-based wildlife habitat modeling framework called “HABIT@” developed by the Landscape Ecology Lab of the University of Massachusetts Amherst. Note, for other species (typically birds) where extant occurrence data are readily available throughtout the Northeast via programs such as the Breeding Bird Survey, Landscape Capability also includes a climate niche model and a prevalence model. However, for black bear these models were not generated due to the lack of a regional and readily accessible occurrence dataset for this species.

The habitat capability models developed using HABIT@ reflect the quantity, quality, and accessibility (collectively referred to as “capability”) of habitat across the landscape for each year assessed. The habitat models are based on ecological settings grids (spatial datasets) developed for the Northeast, such as cover type (largely derived from the Northeast Terrestrial Habitat Map prepared by The Nature Conservancy and Northeastern states), roads and development, and forest biomass (for forest species). The models are spatially-explicit: the value at each cell (location) depends not only on the resources available at that cell, but on resources available in the neighborhood, on the configuration of those resources, and nearby impediments to movement. However, HABIT@ does not model population dynamics or population viability.
