TreeGOER Köppen-Geiger Zone Distributions: Observations for 48,129 tree species across the 30 climate zones for 1931-1960, 1961-1990 and 1991-2020 climates

TreeGOER (Tree Globally Observed Environmental Ranges) is a database that documents the environmental ranges (minimum, maximum, median, mean and 5%, 25%, 75% and 95% quantiles) for 48,129 tree species and for 51 environmental variables, including 38 bioclimatic variables, 8 soil variables and 3 topographic variables. TreeGOER is available from the following Zenodo archives: https://doi.org/10.5281/zenodo.7922927

The TreeGOER ranges were calculated after cleaning occurrence records and standardizing species names with the WorldFlora R package to World Flora Online or the World Checklist of Vascular Plants for a global GBIF occurrence download of 44,267,164 occurrences (GBIF.org 2021 GBIF Occurrence Download https://doi.org/10.15468/dl.77gcvq). The process of compilation of TreeGOER with 30 arc-seconds global grid layers, two examples of BIOCLIM applications that investigated the effects of climate change on global tree diversity patterns and R scripts to repeat these analyses have been described by Kindt, R. (2023). TreeGOER: A database with globally observed environmental ranges for 48,129 tree species. Global Change Biology 29: 6303–6318. https://onlinelibrary.wiley.com/doi/10.1111/gcb.16914.

This Zenodo archive documents the occurrence of the same previously compiled and cleaned observations for the TreeGOER across global raster layers that document the 1931-1960, 1961-1990 and 1991-2020 Köppen-Geiger climate zones. These global raster layers were created for the following article:

The Köppen-Geiger classifcation maps, associated confidence maps, and underpinning monthly near-surface air temperature and precipitation climatologies in netCDF format can all be downloaded here.

For each of the 48,129 tree species, the distribution is given for

• Historical climates: number of observations in the 1931-1960, 1961-1990 and 1991-2020 Köppen-Geiger Zone climate zone
• Mixed climate: number of observations in the 1931-1960 Köppen-Geiger Zone climate zones if observations were before 1961, in the 1961-1990 Köppen-Geiger Zone climate zones if observations were between 1961 and 1990, and in the 1991-2020 Köppen-Geiger Zone climate zones if observations were after 1990
• Static climate: number of observations if those observations remained in the same Köppen-Geiger Zone climate zones
