Know the Guayubira tree: one of the native timber species of the missionary jungle
With information from the Native Missions Species Manual (2024), developed in collaboration between the Faculty of Forest Sciences of the UNAM and the United States Forest Service (USFS) through the Project Update and Edition of the Wood Identification Manual of the Missionary Jungle, we share information from each digital tab that includes dendrological and anatomical characteristics. The manual was elaborated in the Wood, Dendrology and Dendrocronology Anatomy Laboratory (LAMDYD) of the Faculty of Forest Sciences in Eldorado, National University of Misiones.
