Dryland plant co-occurrence and associated functional trait data

This data is associated with the MSc dissertation titled "Drivers of plant-plant interactions in global drylands". The first aim of this research was to determine whether climate, edaphic and grazing variables drive plant-plant interactions in global drylands. The second aim was to determine whether the functional traits of plants play a role in determining the interaction outcome. This research uses data collected as part of the BIODESERT project, a global collaborative survey conducted in drylands, led by Dr. Fernando T. Maestre. Data were collected in 97 plots from 29 sites in 10 countries. The data include a co-occurrence survey (used to estimate plant-plant interaction outcomes), a functional trait survey, as well as climate, edaphic and grazing pressure data for each plot.
