Global planted forest data for timber species

Discerning whether certain timber species were harvested from natural forests versus less restricted planted forests can help ascertain the legality of wood products that enter the global market. However, readily available global planted forest data to the species level have been scarce. We confronted the need for such data by developing a two-pronged dataset, consisting of ‘polygon’ and ‘non-polygon’ location-based data, collectively, Planted Forest Timber Data. We obtained the polygon data from the World Resources Institute’s Spatial Database of Planted Trees v2.0, extracting data specific to traded timber species. We derived the non-polygon data from peer-reviewed literature and government documents. The polygon dataset encompasses 27 countries and 253 species and the non-polygon dataset spans 91 countries and 447 species. The polygon data are stored among 27 geopackages, one for each country. Each summarized row of polygon data contains up to 13 possible fields. The non-polygon data..., The Planted Forest Timber Data is composed of two types of information, polygon and non-polygon data, divided into two distinct living datasets. The polygon dataset includes visual delineations of the planted forest boundaries. These data are organized into GeoPackages with an accompanying summary table that links the collective data together. The planted forest plots in the non-polygon dataset do not have delineated boundaries, but still have species information at least at the country level. The polygon dataset is composed of a subset of the Spatial Database of Planted Trees v2.0, specifically the portion of data that pertained to tree species commonly associated with the timber trade. We used government Lacey Act data and the Botanic Gardens Conservation International’s Working List of Commercial Timber Species to identify and isolate the species that qualify as timber. We also calculated the area of each planted forest plot. We assembled the non-polygon dataset by querying scientifi..., , # Global planted forest data for timber species Access the polygon dataset on Zenodo ([https://zenodo.org/records/14010483](https://zenodo.org/records/14010483)) Access the non-polygon dataset on Dryad ([https://doi.org/10.5061/dryad.2280gb626](https://doi.org/10.5061/dryad.2280gb626)) Access the article associated with the polygon and non-polygon datasets on Nature ([https://doi.org/10.1038/s41597-024-04125-y](https://doi.org/10.1038/s41597-024-04125-y)) The Planted Forest Timber Data (PFTD) consists of two living datasets, polygon and non-polygon. These data include planted forest plots for timber to the species level, with locations at least to the country level. Between the two datasets, the planted forests range from small experimental plots to large commercial operations. The polygon data includes visual delineations of the planted forest boundaries. The non-polygon data lack delineated boundaries but have species information at least at the country level.
