Case 25 - Retention forestry in Southern Patagonia to improve biodiversity conservation and ecosystem services in managed landscapes
|Please read the OpenNESS case study booklet 'Ecosystem services in operation' for the final outcomes of the cases. More detailed information about the cases and the tools and methods used can be found on Oppla: www.oppla.eu|
Southern Patagonia has large pristine areas, which quickly are incorporated into the management activities (e.g. forestry). Recently, only economic values were used to develop silviculture strategies, but to date biodiversity conservation and ecosystem services were included, to achieve forest management sustainability. Our case study includes a forestry proposal with regional interest, but also includes a worldwide interest. It includes the Variable Retention approach, and few examples exist for the Southern Hemisphere. Variable retention approach is a silvicultural system that retains forest structural elements for at least one rotation in order to preserve environmental values associated with structurally complex forests.
The mains tasks are:
- Quantify economic, biodiversity and ES values at regional levels.
- Quantify the impacts of traditional management over biodiversity and ES values.
- Monitoring these effects in long-term plots in the framework of large scale operations (ranches and sawmills).
- Develop new forest management strategies using the variable retention approach.
The study will demonstrate the advantages of the different proposals over biodiversity and ES values, and the costs for the companies and the society. These studies consider the feasibility of use of these practices by the local stakeholders. The case study improves the local forestry with practical recommendations, improving the conservation in the managed forests.
The case study leaders are Dr Guillermo Martínez Pastur and María Vanessa Lencinas from CADIC CONICET (Ushuaia, Tierra del Fuego, Argentina), and Pablo Luis Peri (Río Gallegos, Santa Cruz, Argentina). Several non-project stakeholders are involved as part of the Case study Advisory Board, including companies, universities and forest officers (national and province institutions).
