The USGS Earth Resources Observation and Science (EROS) Center produces near-real-time estimates of annual herbaceous land cover for the Great Basin, Snake River Plain, Wyoming, and contiguous areas in the United States.

Estimates are based on enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) data at 250-meter resolution.

EROS has produced four datasets in total, with two editions for 2017 and two for 2018.

The most recent update is available for direct download from this page. To access prior estimates, visit that page and scroll down to “Associated Items.”

EROS previously produced near-real-time, 250-meter annual cheatgrass percent coverage estimates for 2016 and 2015 for the Northern Great Basin.

Cheatgrass Dieoff Map

Cheatgrass Dieoff Time-series Dynamics (2000 – 2010)

Cheatgrass (Bromus tectorum L.) is a winter annual grass that has invaded and altered the shrub steppe ecosystem in the Great Basin for about 100 years. This highly competitive grass invades recently disturbed areas and then outcompetes most native vegetation by using requisite resources like soil water and nutrients in early spring before other native plants. It also can alter its phenotype and...

Near-real-time Herbaceous Annual Cover in the Sagebrush Ecosystem, USA, July 2018

This dataset provides a near-real-time estimate of 2018 herbaceous annual cover with an emphasis on annual grass (Boyte and Wylie. 2016. Near-real-time cheatgrass percent cover in the Northern Great Basin, USA, 2015. Rangelands 38:278-284.) This estimate was based on remotely sensed enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) data g
