This database, which accompanies the previously discussed database, NDP-072, is used to support a meta-analysis of research results on the response by herbaceous vegetation to increased atmospheric CO₂ levels, and was also compiled from the published literature.

Seventy-eight independent CO₂-enrichment studies, covering 53 species and 26 response parameters, reported mean response, sample size, and variance of the response. An additional 43 studies, covering 25 species and 6 response parameters, did not report variances.
