A regional survey in California and Nevada of plant species dynamics under shrubs and in the open from 2019-2020

A synthesis of field data from vegetation survey 0.5m plots.
A total of 601 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 27.
Lat and long are in degrees decimals to within 5 m.
Primary data and findings summarized in this publication.
Positive associations with native shrubs are intense and important for an exotic invader but not the native annual community across an aridity gradient.
