Dataset Overview

These are raster maps of American black bear (Ursus americanus) scenario-simulated persistence and resistance to change throughout New England. Rasters display species spatial persistence (single-scenario) and resistance (across scenarios) as projected by the NELFP scenarios: Business-As-Usual, Connected Communities, Yankee Cosmopolitan, Go It Alone, and Growing Global. Persistence maps are binary and indicate locations where species probability of occurrence was high (p > 0.7) under current (2010) conditions and remained high (p > 0.7) under scenario projected (2060) conditions. Resistance maps isolate areas of focal species persistence across all NELFP scenarios. Resistant pixels are sub-classified according to patterns of change in occurrence probability; pixel classifications include (1) "resistant-constant", (2) "resistant-increasing", (3) "resistant-decreasing", and (4) "resistant-variable". Persistence and resistance maps were derived from species distribution models developed through expert elicitation and mixed modeling methods, and climate and landcover conditions for 2010 and 2060.
