The Tallo database (v 1.0.0) provides tree measurements for 5,163 tree species and 61,856 globally distributed sites. The database can be accessed via https://zenodo.org/record/6637599 and has been fully described in Jucker et al. 2022. Tallo: A global tree allometry and crown architecture database. Global Change Biology, 28, 5254–5268. https://doi.org/10.1111/gcb.16302. Data provided in this archive show the taxonomic matches with World Flora Online (Borsch et al. 2020) for two versions of its taxonomic backbone data set. The first version (v. 2021.12) was used also to standardize species names for the latest version of the Agroforestry Species Switchboard and during the compilation of the TreeGOER (Tree Globally Observed Environmental Ranges; Kindt 2023) and GlobalUsefulNativeTrees (GlobUNT; Kindt et al. 2023) databases. The second version (v. 2023.03) was the most recent version available online. Taxonomic matching was done via the WorldFlora R package (Kindt 2020, see example scripts for a different taxonomic matching exercise here). Taxonomic matching was achieved for all taxa listed in the Tallo database, except for Lithocarpus orocola. Presence of a taxon in the TreeGOER and GlobalUsefulNativeTrees databases has been flagged by showing the number of records used in TreeGOER to calculate ranges for environmental variable bio01 and by the number of native countries in GlobUNT, respectively. The development of this archive was supported by the Darwin Initiative to project DAREX001 of Developing a Global Biodiversity Standard certification for tree-planting and restoration, by Norway’s International Climate and Forest Initiative through the Royal Norwegian Embassy in Ethiopia to the Provision of Adequate Tree Seed Portfolio project in Ethiopia, and by the Green Climate Fund through the IUCN-led Transforming the Eastern Province of Rwanda through Adaptation project.
