Biodiversity metrics during experimental drought and restoration in a coastal prairie in Santa Cruz, CA, USA in 2019 and 2021

Various biodiversity metrics of restored, unrestored, droughted and ambient rainfall plots derived from plant community data in 2021 and trait data from 2019. Different facets of metrics include: taxonomic, functional and phylogenetic, that is, the average relative total native cover in a plot determined from an average of six 0.25 m² quadrats; the total number of unique native plant species in a plot (richness); the total number of unique plant taxa in a plot (alpha); the nearest taxon distance, i.e. the abundance weighted phylogenetic distance at the 0th quantile; the abundance weighted phylogenetic distance at the 10th quantile; the mean phylogenetic distance; i.e. the abundance weighted phylogenetic distance at the 50th quantile; functional richness, a measure of the total trait space occupied; functional evenness, a measure of the relative distribution of traits in an occupied trait space; functional divergence, a measure of the relative divergence of traits in an occupied trait space, and functional dispersion, a measure of the relative disperion of traits in an occupied trait space determined through relative abundances and dominance.
