Trade-offs among ecosystem services under different pinion harvesting intensities in Brazilian Araucaria Forests

<p>Assessing the consequences of human exploitation at different intensities on ecosystem services is important in the Brazilian <i>Araucaria</i> Forest biome, because it has been drastically reduced, mainly due to the exploitation of <i>Araucaria angustifolia</i> (Bertol.) Kuntze for wood. The inclusion of <i>A. angustifolia</i> on the list of Brazilian endangered plant species places the harvesting of <i>Araucaria</i> nuts as the most important provisioning service in this type of ecosystem. The aim of this study was to determine the trade-offs related to provisioning, supporting and regulating ecosystem services in the <i>Araucaria</i> Forest at different intensities of nut harvesting, by addressing ecosystem attributes that assure forest sustainability. Six indicators of ecosystem services were evaluated in harvested and non-harvested areas in Brazilian <i>Araucaria</i> Forest fragments. Trade-offs were examined under five harvesting intensities. The supporting services were the most sensitive to the harvesting intensity. The results indicate that a harvesting threshold of between 60% and 85% of the nuts produced guarantees forest sustainability. In addition, areas under higher harvesting intensities provide more short-term benefit services at the local scale that can be included in the formal market.</p><p><b>EDITED BY</b> John Parrotta</p><p></p> <p><b>EDITED BY</b> John Parrotta</p>
