A meta-analysis of species richness and restoration outcomes globally.

Species richness is a fundamental component of ecological research including restoration. Managing for enhanced native species richness in restoration is a powerful goal and outcome; nonetheless, local species richness can also be used as a mechanism to decide on the lands to acquire, protect, and restore. Here, a meta-analysis was used to test the hypothesis that local species richness is a viable consideration in predicting varied restoration outcomes as identified by primary researchers in drylands.
