Fire and the functional organization of the tree community: implications for forest restoration at RESEX Tapajós-Arapiuns
Community Ecology, Functional Traits, Ecological Restoration.
Tropical forests are responsible for global sustainability. In this context, fire emerges as a threat as it affects not only the species vulnerable to fire, but also the taxonomic and functional compositions and diversities of communities and alters the structure of the landscape, limiting the maintenance of biodiversity and the provision of essential ecosystem services. This project aims to understand how arboreal vegetation responds to fire, through functional attributes, and what are the implications for the resilience and restoration of the Amazon rainforest. The study is linked to the project “Recovery of areas degraded by forest fires in communities/villages of resurged Indians in western Pará” (CNPq/Prevfogo-Ibama) and is being carried out in the Tapajós-Arapiuns Extractive Reserve, located in the western region of the state. from Pará, Brazil. In thirteen forest sites, eleven burned in 2015/2016 (as a result of El Niño) and three unburned (control areas), the most abundant species (species that, when adding up their relative abundances, make up 50% of the total abundance) are having 11 functional attributes obtained (eg, bark thickness, regrowth capacity, wood density). Among the expected products are: (1) the publication of a scientific article in an international journal with good ratings on ecology and restoration (Qualis A from CAPES), (2) support for policies and initiatives that help to promote both maintenance and restoration of vegetation after fire. It is also envisaged that this project will help in models of ecological restoration projects, which add income generation and local development to communities and, (3) consolidation of a research group in fire ecology and restoration of tropical forests that have by fires.
