Summary

Values represent percent of surrounding landscape (5K) are dominated by sagebrush cover. Reclassified LANDFIRE 2013 Existing Vegetation Type by selecting the ecological systems containing sagebrush (Codes: 2080, 2125, 2126, 2220, 2064, 2072, 2079, 2124) to create a binary raster dataset with 1 for the sagebrush land cover types and zero for all others.To incorporate sagebrush lost to fire in fires since the Landsat was flown in 2010 that Landfire was derived from, I used fire perimeters from 2011,2012, & 2013 to reclassify pixels designated as having sagebrush as 0 (not having sagebrush), which assumes a homogenous burn (in reality there may be patches of sagebrush left within a burn perimeter). I then ran focalsum command in spatial [...]

Purpose

Map was created to evaluate fire and invasives priority landscapes witihing greater sage-grouse habitat. The basis for using this map was KNICK, S. T., AND J. W. CONNELLY. 2010. Greater sage-grouse: ecology and conservation of a landscape species and its habitats. Studies in Avian Biology 38. University of California Press, Berkeley, CA and KNICK, S.T., S.E. HANSER and K.L. PRESTON. 2013. Modeling ecological minimum requirements for distribution of greater sage-grouse leks: implications for population connectivity across their western range, U.S.A. Ecology and Evolution. 3(6) 1539-1561. These data can be reclassified into the 3 classes of sagebrush deemed relevant for sage-grouse, 0-25% sagebrush landscape cover (Value =1) where persistence of leks is less likely, 25-65% sagebrush landscape cover (value =2) where persistence of leks has a positive relationship to more sagebrush cover (between 25 and 65%) and > 65% (value =3) where sage grouse persistences is most likely.
