Protection measures for the Araucaria Forest and their efficiencyin the conservation of Araucaria angustifolia in southern Brazil

Abstract

Forests require sustainable management due to the long cycle of the species, for the balance of the ecosystem, on structure or processes on which the species depend and for the socioeconomic development. This study shows the effect of protection measures (no management, conservation) and their results for the structure of the forest available in official publications and scientific articles. These studies have used statistical methods and compile different information techniques from inventories and scientific research (diagnosis and applied analysis) that evaluated, compared results and presented conclusions on the subject. We argue that there are uncertainties about the threat of extinction and that the lack of management can increase disinterest in the forest resource. The overexploitation of edible seeds can destabilize the dynamics and regeneration of the forest ecosystem. The ecosystem, economic, structure, diversity, reproduction and production losses of forest masses due to non-use of resources are greater than the benefits. The results indicated the need for sustainable forest management as a public policy for the conservation of the species and the Mixed Ombrophilous Forest in southern Brazil.
