Connectivity of Natura 2000 forest sites
This report describes the JRC integrated model and derived results on the connectivity of Natura 2000 sites (only sites including forest). The model allows a harmonized, easily reproducible and automated EU wide assessment and comparison across countries. The Natura 2000 network is first characterised structurally in terms of simple (physically isolated) and complex sub-nets (spatially connected sites). Natura 2000 shares of complex sub-nets range from 40% in Bulgaria to 5% in Latvia. Second, the functional connectivity of the Natura 2000 subnets is addressed to tackle fragmentation by grey infrastructure including roads and intensive agriculture for species dispersing 500 m in average. A European-wide land use based friction map was created as a proxy of landscape suitability to measure functional (least-cost) distances between sub-nets. Functional connectivity was assessed according to two foci: one focused more on the area of subnets, another one on the inter-site landscape suitability and distances. The site area weighted index values ranges from 15 % (Denmark) to 78% (Malta). Best connected subnets with respect to inter-site landscape and distance were in Bulgaria, Belgium, Portugal, Ireland and Malta. High shares of functionally isolated subnets were in Greece, Denmark and Portugal. Functionally isolated sites and sites of key importance for connectivity were identified for two countries. The JRC model and derived analysis constitute a potential input to help building a Green Infrastructure in Europe. It allows the connectivity of protected areas to be assessed, isolated areas to be identified. It could guide regional landscape planning of forest conservation and restoration efforts. It could also contribute data and indicators relevant to the Habitat Directive (Article 10), to Rural Development Programmes (CMEF), the Water Framework Directive (NWRMs), and Target 1, 2 and 3 of the EBS. ; JRC.H.3-Forest Resources and Climate
