RCMAP Background and Data Access

Rangeland managers need information on the current vegetation condition and how the landscape has changed through time. To address this need, scientists from the USGS and Bureau of Land Management (BLM) developed the Rangeland Condition Monitoring Assessment and Projection (RCMAP) project. These data classify western U.S. rangelands as fractional (0-100%) cover of ten ground cover components (annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub height). Maps are produced for each year in a time-series stretching from 1985 to 2023, key to understanding vegetation response to climate change, changing management practices, and to disturbance. 

In this video, we describe how to access RCMAP data by various means on the MRLC.gov website, FTP, and Google Earth Engine. Users can also explore the spatial and temporal patterns of the data on the MRLC Rangelands viewer.
