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).本数据发布包含用于南加州灌木丛中五种植物物种（绒毛金露梅（Vogel）Brouillet、腺毛红莓苔子（Eastw.）、粗叶蓝花菜（Benth.）、簇毛补血草（Benth.）和三裂蓝花菜（A. Heller））的利用-可获得性建模的信息。利用数据（已知物种位置的经纬度）收集自标本馆记录和实地调查。可获得性数据对应于研究区域内尚未进行物种采样的位置。地点位于阿尔伯斯等面积平面投影中。对应的历史（1951-1980年）30年平均气候数据通过盆地特征模型（BCM）获得，该模型模拟了气候与地形和土壤等景观属性之间的相互作用，并为加利福尼亚的历史和未来气候提供270米分辨率的网格。气候变量包括温度和降水季节性、最热和最冷季度的降水量、冬季最低温度、夏季最高温度、蒸散量和气候水亏缺。收集数据以模拟多种灌木丛植物物种的适宜栖息地。有关这些数据的更多信息以及利用和气候数据的进一步细节，请参阅Johnson等（2021年）和Riordan等（2018年）。
