Description
The Tallo database is a global collection of 498,838 georeferenced and taxonomically standardized individual-tree records compiled across 61,856 sampling sites globally. Spanning 5,163 tree species, 1,453 genera, and 187 plant families, Tallo provides individual-tree measurements of stem diameter (DBH), total tree height, and mean crown radius across all major terrestrial biomes.
The database was created to support research in forest ecology, remote sensing, and global vegetation carbon modeling. It is described in detail in Jucker et al. (2022).
This dataset is available through BigQuery at
earth-engine-public-data.tallo.tallo_v1.
