Sagebrush Types, Soil Regime Classes, and Fire Frequencies in Greater Sage-grouse Population Areas of the Wyoming Basin (1984-2013)

This three-band, 30-m resolution raster contains sagebrush vegetation types, soil temperature/moisture regime classes, and large fire frequencies across greater sage-grouse population areas within the Wyoming Basin sage-grouse management zone. Sagebrush vegetation types were defined by grouping together similar vegetation types from the LANDFIRE biophysical settings layer. Soil moisture and temperature regimes were from an USDA-NRCS analysis of soil types across the greater sage-grouse range. Fire frequencies were derived from fire severity rasters created by the Monitoring Trends in Burn Severity program. The area of analysis included the greater sage-grouse populations areas within specific management zones. Methods used to derive these data are detailed in the report [Brooks, M.L., Matchett, J.R., Shinneman, D.J., and Coates, P.S., 2015, Fire patterns in the range of greater sage-grouse, 1984-2013; Implications for conservation and management: U.S. Geological Survey Open-File Report 2015-1167, 66 p., http://dx.doi.org/10.3133/ofr20151167]

本数据集为30米分辨率的三波段栅格数据，涵盖怀俄明盆地大艾草松鸡（Greater Sage-Grouse）管理区内该物种种群分布区域的蒿灌植被类型、土壤温湿度格局（soil temperature/moisture regime）类别，以及大型火灾发生频率。其中，蒿灌植被类型通过归并LANDFIRE生物物理设置图层中的相似植被类型得到；土壤温湿度格局类别数据源自美国农业部自然资源保护局（USDA-NRCS）针对大艾草松鸡分布区开展的土壤类型分析；火灾频率数据则由火灾严重程度监测趋势（Monitoring Trends in Burn Severity）项目生成的火灾严重程度栅格数据推导而来。本次分析的范围涵盖特定管理区内的大艾草松鸡种群分布区域。本数据集的生成方法详见下述报告：Brooks, M.L.、Matchett, J.R.、Shinneman, D.J.与Coates, P.S.于2015年发表的《1984-2013年大艾草松鸡分布区火灾格局：保护与管理启示》，美国地质调查局公开文件报告2015-1167，共66页，链接：http://dx.doi.org/10.3133/ofr20151167
