Measures of local grizzly bear abundance and surrounding road density and food supply

Data fields: 1) "DNA_sampling_cell_ID" is the 7x7 km cell used to allocate hair snag sites and used as a random effect in models; 2) "Session_number" is the 2 week session number of sampled site between 25 May and 17 July 2004; 3) "Number_grizzlybears" is the unique bears detected at hair snag site; 4) "Road_density_7440m" is the moving window road density (km/km^2) within a 7440 m radius window calculated in ArcGIS; 5) "Shep_can_fruit_DigE_1690m" is the modeled digestible energy (kcal) of Shepherdia canadensis fruit within a 1690 m radius of the hair snag site summarized in an ArcGIS moving window; 6) "Shep_can_fruit_DigE_7440m" is the modeled digestible energy (kcal) of Shepherdia canadensis fruit within a 7440 m radius of the hair snag site as summarized in an ArcGIS moving window; 7) "Ungulate_DigE_7440m" is the digestible energy (kcal) of ungulate matter within a 7440 m radius of the hair snag site as summarized in an ArcGIS moving window; 8) "NDVI_JulyMax_1690m" is the Natural Difference Vegetation Index (NDVI) maximum value in the month of July from MODIS remote sensing data during the year 2006 with values averaged within a 1690 m radius of the hair snag site as summarized in an ArcGIS moving window; 9) "NDVI_JulyMax_7440m" is the Natural Difference Vegetation Index (NDVI) maximum value in the month of July from MODIS remote sensing data during the year 2006 with values averaged within a 7440 m radius of the hair snag site as summarized in an ArcGIS moving window.
