Propuesta de manejo silvicultural para el arbolado encontrado en el Conjunto Residencial Súpermanzana Dos ubicado en la localidad de Kennedy

Abstract

The main objective of this work is to formulate a proposal for a silvicultural management plan for the Supermanzana 2 Multifamily Complex, located in Kennedy, Techo neighborhood, in the city of Bogota. This complex, built between the 1950s and 1960s as part of the “Ciudad de Techo” project, has 1069 apartments distributed in 12 blocks and is characterized by its extensive green areas and abundant trees, which constitute an important habitat for native and migratory birds. The existing trees are mostly introduced species such as urapan (Fraxinus chinensis), Japanese acacia (Acacia melanoxylon), araucaria (Araucaria heterophylla), and rubber (Ficus elastica), the result of unplanned plantings by the first inhabitants of the complex. This lack of planning has generated various problems related to the infrastructure, as well as differences among the residents regarding the management of the trees, evidencing the absence of clear strategies for their maintenance and control. To address these problems, a forestry census was carried out that included a photographic record and georeferencing of each individual tree, using the Silvicultural Information Collection Form and the Technical Record Sheet N.2 established by the Bogota Secretariat of the Environment. Based on this data, 12 critical species were prioritized, proposing specific interventions such as pruning, sanitary treatments, fumigation and, in extreme cases, controlled felling. The proposal also includes a catalog with 11 viable tree species for future planting, selected according to their ability to adapt to the conditions of the site and their contribution to ecosystem services. In addition, three complementary programs were designed for the implementation of the plan and a budget was prepared based on the District Plan for Urban Forestry, Green Zones and Gardening of Bogotá D.C. (2019-2030).
