Invasive Plant Cover in the Mojave Desert, 2009 - 2013 (ver. 2.0, April 2021) We assessed the impacts of co-occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA by analyzing the distribution and co-occurrence patterns of three invasive annual grasses known to alter fuel conditions and community structure: Red Brome (Bromus rubens), Cheatgrass (Bromus tectorum), and Mediterranean grass (Schismus spp.: Schismus arabicus and Schismus barbatus), and an invasive forb, red stemmed filaree (Erodium cicutarium) which can dominate postfire sites. We developed species distribution models (SDMs) for each of the four taxa and analyzed field plot data to assess the relationship between invasives and fire frequency, years postfire, and the impacts...

The data include: (1) A shapefile of the Mojave Desert that was used as our study area boundary (MojaveEcoregion_TNS_UTM83.shp). The original shapefile was obtained from NatureServe in 2009; (2) Three Tagged-Interchange Format (TIF) raster datasets representing probability of ignition, fire frequency, and burn severity. Resolution equals 30 meters, projection equals UTM Zone 11N. These data support the following publication: Klinger, R., Underwood, E.C.,...

The species has been considered for listing under the federal Endangered Species Act multiple times, and was most recently ruled to not warrant protection as of September 2015. Nevertheless, the species faces threats from increasing wildfire frequency and changing climate, which are identified frequently as two environmental drivers contributing to declines of sage-grouse populations. To help inform a threat assessment within the Great Basin for listing sage-grouse in 2015 under the...
