Considering that the National Police of Colombia is one of the institutions having signed the "Pacto Intersectorial por la Madera Legal en Colombia" designed to verify by means of an inter-sector covenant or alliance, the legality and the legal source of both the wood and the chain of custody, a microscopic characterization of seven threatened forest species, as an academic contribution to police activity within the framework of environmental legislation. This research not only contributes to state environmental management but also as an incentive to the preparation of a technical field guide to the recognition of woods, since Colombian Police, as a control entity in the mobilization of biological diversity specimens, leads -apart from meeting its specific mission-, protection, preservation, recovery or reclamation or natural resources in support of the other regional and local environmental authorities, by deploying strategies oriented to prevent the illegal wood traffic which, at present, amounts to 40% on average, nationwide. This study carries out a microscopic characterization of the Aspidospermapolyneuron, A. megalocarpon, Humiriastrumprocerum, Hymenaeaoblongifolia, H. courbaril, Isidodendrontripterocarpum, and Juglansneotropica species, as a tool for the identification of samples serving to support verification, control, and the post-seizure process in illegal wood mobilization.
