SRCE: Biodiversity reservoirs Open Plains of SRCE Poitou-Charentes

Open plains classified as reservoirs of biodiversity by the SRCE Poitou-Charentes. __Origin__ 1 — The biodiversity reservoirs of this subtrame have been identified by cartographic modelling, based on parameters of landscape ecology (naturality, connectivity, surface-compacity, fragmentation, heterogeneity). For this sub-trame, additional information on hedge density, path density and high natural values of SOLAGRO has been taken into account in order to better characterise open plains. In addition, a filter on the density of vineyards, produced from land use data CLC has been taken into account to avoid valuing intensive viticulture sectors such as Cognaçais, as a reservoir of potential biodiversity. Modeled biodiversity reservoirs with more than 50 % and between 25 % and 50 % vines are degraded in the final rating of the modeling. The modelling carried out by CEREMA DTER SO. 2 — Potential biodiversity reservoirs have been prioritised in order to select the most spaces functional, corresponding to the biodiversity reservoirs of the territory. The criteria used are as follows: modelling potential (M), area (S), membership of a continuity of n°#x27; national importance (CIN), overlap with mandatory or non-compulsory biodiversity reservoirs (Z1 and Z2), presence of n°#x27; indicator species (E). 3 — Pre-identified biodiversity reservoirs were presented at the Open Plains Working Group. They were reviewed, adjusted and appointed. The adjustment mainly concerned a recaling of RBs with perimeters subject to previous assessments (MAET, ZNIEFF, SPAs). __Partner organisations__ DREAL Poitou-Charentes, MTDA Agency __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.sigena.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=841180) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/4e9e2ffb4908074740a2c38c4afec0bc07bfbe77)
