Exotic Annual Grass
The Exotic Annual Grass (EAG) abundance dataset provides early season percent cover estimate of the exotic grass species in 30m spatial resolution for a mapped year in rangeland ecosystems of western United States. We plan to release these EAG estimates multiple times each year in early growing season. EAG is a continuous field consisting of abundance of non-native grass species whose life history is complete in one growing season. Cheatgrass (Bromus tectorum) is a dominant species, but this dataset also includes Bromus arvensis L., Bromus briziformis Fisch. & C.A. Mey. Bromus catharticus Vahl, Bromus commutatus Schrad, Bromus diandrus Roth, Bromus hordeaceus L., Bromus hordeaceus spp. Hordeaceus, Bromus japonicus Thunb, Bromus madritensis L., Bromus madritensis L. ssp. rubens (L.) Duvin, Bromus racemosus L., Bromus rubens L., Bromus secalinus L., Bromus texensis (Shear) Hitchc, and medusahead (Taeniatherum caput-medusae (L.) Nevski). A main objective of releasing these maps is to provide a tool for better monitoring EAG dynamics and informing conservation and management efforts at local to regional scales. (Read More)

Tree Canopy
NLCD tree canopy cover geospatial datasets with spatial resolutions of 30 m are produced by the USDA Forest Service. Tree canopy cover is derived from multi-spectral satellite imagery and other available ground and ancillary information. Tree canopy products for the period 2011-2021 are available for the conterminous United States, and by summer 2023, they will also cover coastal south east Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands.

RCMAP - Time-Series - Cover
V5 RCMAP Factsheet.pdf2.14 MB
Maximizing Accuracy of Rangeland Data- RCMAP article April 2024
The RCMAP product suite includes 10 components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub height. Data characterize the percentage of each 30-meter pixel in the Western United States covered by each component for each year from 1985-2023 - providing change information for 39 years. Because of file size limitations, individual years of component cover data are packaged in three time intervals including 1985-1996, 1997-2008, and 2009-2023. Perennial herb and non-sagebrush shrub are derivatives of herbaceous and annual herbaceous cover, and shrub and sagebrush cover, respectively. (Read More)

RCMAP - Future Projections - 2020s, 2050s, and 2080s
RCMAP projected cover products characterize the fractional (i.e., percentage) cover of shrub, herbaceous, bare ground, litter, sagebrush, tree, and annual herbaceous in each 30-meter pixel in the Western United States. Projected data include three time periods (2020s, 2050s, and 2080s) and two climate scenarios (Representative Concentration Pathways [RCP] 4.5 and 8.5). Component cover were harmonized so that the sum of bare ground, shrub, herbaceous, tree, and litter cover adds to ~100% and secondary components sagebrush and annual herbaceous cover were harmonized to their respective primary components of shrub and herbaceous cover, (so their cover could not be greater than their primary component). These products have been produced by USGS in collaboration with the Bureau of Land Management. Component products are designed to be used individually or combined to support a broad variety of applications. Data are packaged by time-period and climate scenarios (six). Additionally, for comparison to reference conditions, a scenario based on 1991-2020 climate normal is available. (Read More)

Ecological Potential
Rangeland Ecological Potential - Component Cover, Cover Departure, and Vegetation States.
Ecological Potential rangeland fractional cover data products represent the potential cover given the most productive, least disturbed, portion of the 1985-2020 Landsat archive. Models used to predict Ecological Potential cover were trained on ecologically intact sites where annual herbaceous cover is low, no known disturbance or land treatment has occurred over the study period, and bare ground cover is relatively lower than expectations (Read More)
