Improvement of forest management key strategies: a contribution to conservation and sustainable land use
Ecology and Biodiversity of Plants and Ecosystems
Final Report Abstract
In spite of a variety of efforts, tropical forests are still threatened by exploitation and conversion to agricultural land-use. Besides legal protection, sustainable management concepts are essential for stable conservation of these ecosystems. This project aimed at identifying and optimizing the potentials for forest management for three different ecosystems (Tropical Dry Forest, Tropical Mountain Rain Forest, Páramo) along a height- and climate gradient in Southern Ecuador. Therefore, multiple and locally differentiated aspects of forest management have been considered: the direct provision of goods (timber and non-timber forest products) as well as ecosystem services (carbon sequestration, water regulation); moreover, the effects of forest management on biodiversity and the impacts of global changes on resilience indicators and the projected distribution of selected species with high potential for sustainable management or conservation has been investigated. First, the most important forest structure types and possible improvements of management alternatives have been identified for the assessment of different management concepts. We installed comprehensive inventory- or experimental field plots and conducted monitoring for the locally most important criteria of forest management. Finally, we supported the development and application of a sound decision-support tool for land-use optimization in cooperation with our partner projects, taking into account reforestation options in the Tropical Mountain Rain Forest ecosystem and their uncertainties with regard to input parameters and the relevance of different criteria of forest management. In addition, the results of our studies in the Tropical Dry Forest and the Páramo enable to consider the multiple functions of forest management accordingly in order to represent the forestry component in sustainable land-use models. The comprehensive studies have been carried out in close cooperation with other scientific teams from Germany and Ecuador as well as local institutions of relevance for forest management. The direct involvement of Ecuadorian students and young academics and the integration of the results in educational concepts contribute to capacity building and local efforts for the enhancement of environmental competencies.
