Hedgerows for more resilient pine forest

Discussion with stakeholders on how to improve the resilience of intensive pine monocultures with the introduction of hedgerows in the French Landes of Gascony Forest.

On 7 September 2023, a large panel of 24 forest stakeholders gathered in Belin-Béliet (France) for the 2nd BOCAGE FORESTIER Living Lab consultation workshop since the SUPERB project began. The Living Lab was launched a few years ago with the support of the Nouvelle-Aquitaine Region and the forestry sector, aiming at improving the heterogeneity and resilience of maritime pine monoculture landscape towards biotic and abiotic threats. After some preliminary studies including the choice of the most suitable demonstration area and the design of methodologies, our coordination team was pleased to present some concrete implementation of our restoration activities. The workshop began with an indoor meeting with presentations to remind the participants of the SUPERB project and the Living Lab’s objectives, followed by a short field tour to illustrate our activities directly in the forest.

On the one hand, we are carrying out biodiversity sampling in mature hedgerows to understand the effect of landscape connectivity and broadleaved species patch density on the richness of fauna and flora. We have also designed educational panels for each taxon studied to initiate discussions about both the data collection protocol and the first results obtained. On the other hand, we are establishing new hedgerows planting trials in renewed maritime pine stands to refine the technical aspects and be able to provide forest owners with a fully operational solution. The complementary nature of our workshop programme was greatly appreciated by the participants, who now have a concrete understanding of what we mean by ‘forest restoration’ and know exactly what they can expect from future outcomes. The topic was considered so important by some participants that they are asking for wider communications and rapid adoption of these results.

The next steps for the BOCAGE FORESTIER Living Lab are to start planting hedgerows within the demo area with the aim of achieving 10km of linear planted by the end of the project. Restoration sites will depend on the private landowner’s interest in implementing this solution but they may also be determined by the results of the biodiversity sampling, which we will try to synthesize by spring.
