Spatial Database of Planted Trees (SDPT Version 2.0)

Abstract

This paper describes the methods for updating the Spatial Database of Planted Trees (SDPT) in three areas: boundaries, to spatially differentiate planted forests and tree crops from natural and seminatural forests on a global scale; tree species information, to help screen for the illegal exportation of timber products; and carbon sequestration rates, or removal factors, to improve maps of atmospheric carbon dioxide sequestration by planted trees.
