The tree data represents data collected in each ForestGEO research plot, wherein all free-standing trees with a diameter at breast height of at least 1 cm are tagged, measured, and identified to species. The trees are re-censuses every 5 years.

Please use the side-menu to select which region and research plot you would like to request the data from on the left. You will be directed to a pop-up window with the data status that will direct you to the data request form. Each plot has Plot Investigators that require researchers to read and follow the terms and conditions of data use, submit a research project description, planned analyses to be performed on the data, and a description of the data required. Once researchers submit their request, the Plot Investigators will be notified for approval.
