Brome invasion in California Drylands 2015-2018

A synthesis of field data from 0.5m plots.A total of 111654 species observations were summarized to plot-level data here. Each row is a sampling instance, i.e plot. The aridity vector is from this data product: Fick, S. E., and R. J. Hijmans. 2023. WorldClim 2: new 1km spatial resolution climate surfaces for global land areas. International Journal of Climatology <b>27</b>.Lat and long are in degrees decimals to within 5 m.

本数据集整合了0.5米样地的野外实测数据。本次研究共将111654条物种观测记录汇总为样地尺度数据。每一行代表一个采样单元，即一块野外样地。本数据集所用的干旱度矢量（aridity vector）源自以下数据产品：Fick S E与Hijmans R J于2023年发表的《WorldClim 2：全球陆地区域1千米空间分辨率气候表面数据集》，刊载于《国际气候学杂志（International Journal of Climatology）》第27卷。纬度与经度采用十进制度格式记录，定位精度可达5米以内。
