Southern California shrub and subshrub use-availability data

This data publication contains information used in the use-availability modeling of five plant species that occur in southern California shrublands: Acmispon glaber (Vogel) Brouillet, Arctostaphylos glandulosa Eastw., Eriodictyon crassifolium Benth., Eriogonum fasciculatum Benth., and Eriodictyon trichocalyx A. Heller. Use data (latitude, longitude of known species locations) were collected from herbarium records and field surveys. Availability data corresponds to locations in the study region where species have not been sampled. Localities are in an Albers Equal Area planar projection. Corresponding historical (1951-1980) 30 year average climate data for use-availability localities were obtained from the Basin Characterization Model (BCM), which models the interactions of climate with landscape attributes such as topography and soils and provides 270 meter resolution grids for historical and future climate in California. Climate variables include temperature and precipitation seasonality, precipitation of the warmest and coldest quarter, minimum winter temperatures, maximum summer temperatures, evapotranspiration and climatic water deficit.
Data were collected to model suitable habitat for multiple shrubland plant species.
For more information about these data as well as further details on use and climate data, see Johnson et al. (2021) and Riordan et al. (2018).
