NDP-072

A Database of Woody Vegetation Responses to Elevated Atmospheric CO₂
(September 1999)

Curtis, P. S., R. M. Cushman, and A. L. Brenkert

To perform a statistically rigorous meta-analysis of research results on the response by woody vegetation to increased atmospheric CO₂ levels, a multiparameter database of responses was compiled. Eighty-four independent CO₂-enrichment studies, covering 65 species and 35 response parameters, met the necessary criteria for inclusion in the database: reporting mean response, sample size, and variance of the response (either as standard deviation or standard error). Data were retrieved from the published literature and unpublished reports.

NDP-072 is an enhancement of previously published CDIAC DB1018, with additional quality control and documentation.
