Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2025

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2025. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub height; in addition to the temporal trends of each component. Several enhancements were made to the RCMAP process relative to prior generations. 1) The training database was expanded by incorporating new observations from the BLM Analysis Inventory and Monitoring dataset, the Global Biodiversity Information Facility (GBIF) data, Observations for central Idaho (Sorrentino et al. In Prep), and UAV-derived data (Johnston et al. 2025), and additional Landsat scale observations collected by RCMAP. 2) 10 new high-resolution training sites were added in the Great Plains. 3) Enhanced noise filtering post-processing using the Savitsky-Golay filter, and 4) integration of Exotic Annual Grass products into the RCMAP hierarchy. RCMAP data can be used to answer critical questions regarding the influence of climate change and the suitability of management practices. Component products can be downloaded at https://www.mrlc.gov/data and are available in an interactive viewer: MRLC Rangeland Viewer. Additionally, data are available on Google Earth Engine, and as WMS/WCS services Data Services Page | Multi-Resolution Land Characteristics (MRLC) Consortium.
