North American tree provenance trial and relevant historical climate data for seven species

This dataset contains two databases: (1) test_sites_database and (2) trial_results_database. The test_sites_database contains location and climate information for tree provenance trial test sites. The climate information is summarized for the active (planting, measurement) years of the site. The trial_results_database contains the trial results (such as tree height, survival, etc.) for different seed sources associated the tree provenance test sites described in the test_sites_database. It also contains long-term climate summaries for the seed source origin locations. We obtained the trial results from a systemic review of publicly-available scientific studies and appended climate data to facilitate data analysis. Our purpose in providing these datasets is to ensure that the results of a variety tree provenance studies are available for use by researchers and forestry professionals, given how time-consuming and expensive these trials are to establish. When using the data, please also cite the original study. This can be found in the table "Guide to Data Sources", found in the folder "data source information" in both databases. The databases both contain the data in .csv and .txt format.
