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.

The advance of deforestation on protected areas was once again evident this week in the Piñalito Sur Provincial Park, in San Pedro, where the Ministry of Ecology and Renewable Natural Resources confirmed a new case of selective illegal logging. The event occurs in a context of growing concern about the fragility of the environmental control system in rural and border areas, where the scarcity of resources, personnel and logistics limits the capacity of surveillance against criminal organizations organized to steal native woods and market them on the black market in connivance with sawmill owners.
They promote research in pine resins from the NEA
The forestry industry is one of the most important sectors in the economies of Misiones and Corrientes. Thousands of hectares of pine supply the paper, pulp, boards and sawmill industry. Pinus elliottii, one of the species established in the region, in addition to providing wood, is used to produce resin, a non-wood forest product with high demand in the chemical, pharmaceutical and cosmetic industries. In 2\024, resin extraction of approximately 52,6\0\0 tons was achieved from approximately 18,\0\0\0,\0\0\0 trees in production, generating income and jobs with high expansion potential.
