Actualización del inventario forestal de la Universidad Distrital Francisco José de Caldas, Facultad del Medio Ambiente y Recursos Naturales, sede Vivero

Abstract

This document presents the results obtained during the internship "Updating the Forest Inventory of the Francisco José de Caldas District University, Faculty of Environment and Natural Resources, Vivero Campus." The internship focused on collecting forest cover data to obtain updated and accurate information to serve as a basis for proper tree management. Specifically, dasometric data, as well as phytosanitary and risk-related information, were collected. Field evaluations of individual trees were conducted, measuring variables such as circumference at breast height (CBH), merchantable height, total height, and crown depth. A physical and sanitary diagnosis of the crown and trunk was also performed. This information was recorded on the urban tree management forms prepared by the District Secretariat of the Environment. Based on the data obtained, calculations were performed to estimate timber volume, economic value, and stored carbon, and the necessary interventions for each tree were determined. The results showed that the site contains a total of 859 registered trees across a combined area of 5.12 hectares (3.35 ha in area A and 1.77 ha in area B). A strong presence of exotic or fast-growing species was observed, with Acacia melanoxylon being the dominant species in both areas, followed by Pinus patula and Fraxinus chinensis. The technical assessment determined that 85.2% of the trees should be preserved. The remaining 14.8% will undergo scheduled silvicultural interventions: 67 trees (57 in area A and 10 in area B) were determined to be felled due to irreversible poor health, structural defects, or a severe risk of uprooting. The remaining trees will be subject to comprehensive treatments, special treatments, or targeted pruning (for health, stability, thinning, or enhancement) to safeguard the site's safety and improve the health of the trees. On the other hand, a total of 251.52 tons of stored carbon was obtained, and a total valuation of the individuals in both globes was $1,623,191,756 COP. This gives an idea of the importance of the university's forest heritage, the headquarters, and the priority that should be given to it in environmental management processes within the university.
