In an effort to make the FERP data as widely available as possible, this page offers direct access to all the data used in the description of the first three FERP censuses.

The data are fully described in Gilbert, G.S., S.G. Carvill, A.R. Krohn, and A.S. Jones. 2024. Three censuses of a mapped plot in coastal California mixed-evergreen and redwood forest.  Forests  15(1), 164; https://doi.org/10.3390/f15010164.)

The data are also available through Data Dryad as a .csv flat file (https://doi.org/10.5061/dryad.6q573n64s), and on the ForestGEO web site at https://forestgeo.si.edu/explore-data/uc-santa-cruz-termsconditionsrequest-forms.
