Service Description: The indicator uses areas identified as grasslands using LANDFIRE’s Biophysical Settings (BpS) raster dataset (US_140BPS_20180618) along with a cross-walk based on Reeves MC, Mitchell JE (2011) Extent of coterminous US rangelands: quantifying implications of differing agency perspectives. Rangel Ecol Manage 64:1–12 to identify BpS units that are likely to be grasslands during pre-European times. Presence of conifer tree species was developed using USGS National Landcover Database 2021 (NLCD) legend class “42 – Evergreen Forest”. The Evergreen Forest class represents “areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. More than 75% of the tree species maintain their leaves all year. Canopy is never without green foliage.”Grassland conifer encroachment is identified where raster pixels are identified as both “grasslands” and NLCD “Evergreen Forest”

Rangel Ecol Manage 64:1–12 to identify BpS units that are likely to be grasslands during pre-European times. Presence of conifer tree species was developed using USGS National Landcover Database 2019 (NLCD) legend class “42 – Evergreen Forest”. The Evergreen Forest class represents “areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. More than 75% of the tree species maintain their leaves all year. Canopy is never without green foliage.”
