This dataset consists of 31 plant functional trait maps at 1 km resolution with global extent. Plant functional traits are predicted as community-weighted means based on a synthesis of crowdsourced biodiversity data (GBIF species observations, sPlot vegetation surveys, and in situ trait measurements from the TRY trait database) modeled as a function of Earth observation data, including surface reflectance, climatic variables, soil properties, canopy height, and vegetation optical depth. This version of the maps includes traits sourced from all available plant functional types (PFT). PFT-specific maps are in progress and will be available in the future. Note: In addition to using the coefficient of variation and area of applicability layers of the maps, we encourage all who wish to use these maps to take particular note of the model performance for the traits of interest, which can be found both in the raster metadata as well as in Table S1 of the manuscript. The model performance varies significantly across the traits, and so care should be used. Primary manuscript: Lusk, D., Wolf, S., Svidzinska, D. et al. Crowdsourced biodiversity monitoring fills gaps in global plant trait mapping. Nat Commun 17, 1203 (2026). https://doi.org/10.1038/s41467-026-68996-y GeoTIFF multilayer raster description Each GeoTIFF is in Equal Area Scalable Earth projection (EPSG:6933). In addition to the trait predictions, two quality bands are provided. Model performance metrics are also included in the raster metadata. Band number Band name Description 1 The predicted CWM trait values. 2 Coefficient of variation An indicator of model uncertainty derived by comparing the predictions made during model cross-validation. 3 Area of applicability An indicator of model reliability. The area of applicability indicates regions where predictor data used for prediction differs significantly from predictor values seen during model training (see Meyer and Pebesma, 2021).

"Trait" refers to a shortened version of the "TRY trait name", "TRY trait name" refers to the name used in the TRY trait database, and "TRY ID" is the identifier for the trait in the TRY trait database. "Pearson's r" is the cross-validated Pearson's correlation coefficient between the trait map and spatially independent sPlot community-weighted mean trait values. * Experimental traits—model performance below the heuristic threshold of r=0.5. Please consider your use case before incorporating these trait maps into your analysis.
