Of particular relevance for the study of tropical trees, we have a share in several series of international species and provenance trials in the tropics (e.g. Teak, Gmelina, Acacia, Prosopis, Neem, Pinus kesiya, many West African indigenous fruit trees, and Jatropha curcas). We are increasingly involved in the establishment of databases of species information, like the Vegetation Map for Africa, the Agroforestry Species Switchboard  and the Global Tree Knowledge Platform.
