Figure 1

A map of the central drylands of California sampled for patterns in plant associations with and without native shrubs present and with and without a highly invasive plant species. Each point shows a site surveyed for plant occurrences by species. A total of 11 sites were used. Each site was within an arid or semi-arid climate and dominated by the native shrub shrub Ephedra californica with the invasive annual plant species Bromus rubens present at the site level. The relative mean proportions of total site-level plant abundance comprised by Bromus rubens is shown with a heat map per point. The open-source programming language R version 4.3.1 (https://cran.rstudio.com/) was used to create the map. The base layer imagery is sourced from Google (CC BY 4.0, retrieved October 23, 2023) using from the R package ggmap version 3.0.2 (https://cran.r-project.org/web/packages/ggmap/).
