PSDR4 OUIGEF -Outils innovants pour une gestion concertée des forêts

Forests provide multiple services, which sometimes lead to contradictory management issues. The OUIGEF project tested, in three territories of the Auvergne Rhône Alpes region (Massif des Bauges, Chartreuse and Pilat Regional Parks), innovative technical or organizational tools for sustainable forest management reconciling these issues. Forest resource was evaluated by airborne LiDAR on the Grande Chartreuse Forest. The methods developed makes it possible to extract essential parameters for forest management with accurate precision, in a continuous and homogeneous manner. Accessibility to the resource was evaluated using the SYLVACCESS tool. Forests with a protection function were mapped and a field protocol to identify mature forests was finalized. The motivation of private forest owners to log their forests was modelled, integrating both the sociodemographic characteristics of the owners and the biophysical characteristics of their forest plot. The valuation circuits of local wood were analyzed, questioning the processes that build the value of local wood. A first focus dealt with a wood energy platform in the Massif des Bauges PNR, a second showed how the process of building the AOC Bois de Chartreuse, while economically enhancing a local resource, also shed light on the "non-market" values of this resource for the territory. Co-constructed with all forestry stakeholders, an analysis grid evaluates the functions of a forest before it is harvested. The diagnosis helps the manager in choosing appropriate harvesting methods. Downstream, the grid evaluates the quality of the harvesting operation. An online educational game follows the path of a wood chip, from its mobilization in the forest to its combustion, and raises the awareness to the construction of a sustainable wood energy sector. A geo-catalogue gathers information on the data used by researchers and actors involved in forest management. An instruction manual for the use of the data adapted to concrete problems faced by forestry stakeholders is joined. La forêt rend de multiples services, à l’origine d’enjeux de gestion parfois contradictoires. Le projet OUIGEF a testé, sur trois territoires de la région Auvergne Rhône-Alpes (PNR du Massif des Bauges, de la Chartreuse et du Pilat), des outils techniques ou organisationnels innovants, au service d’une gestion forestière durable conciliant ces enjeux. La ressource forestière a été évaluée par un LiDAR aéroporté sur la Forêt Domaniale de Grande Chartr
