Wet to wet Lawns and Heaths on Acid Soil – Ecological Corridors (SRCE)

This dataset lists the various potential ecological corridors for the subtrame lawns and dry wet heaths on acidic soils of the SRCE in the Centre-Val de Loire region. These corridors provide connections between reservoirs of biodiversity, providing species with favourable conditions for their movement and completion of their life cycle. (Article R.317-19 III of the Environmental Code). Two levels of intervention are possible under the CERS: corridors to be restored and those to be preserved. An indicative right-of-way of 3 km should be taken into account on either side of the corridor axis, so as to indicate that they are imprecise movement spindles that should be refined from local knowledge. at the time of declination of the SRCE. The regulations allow that not all biodiversity reservoirs are necessarily connected by ecological corridors (Article R.317-19 II of the Environmental Code). This scenario should be limited and mainly concern biodiversity reservoirs with regard to: the relevance of connecting or maintaining the natural isolation of these spaces (in particular: cases of isolation to prevent the spread of invasive alien species or potential health problems posed by wildlife carrying diseases that can be transmitted to domestic species (e.g. swine fever) or even humans (e.g. rage)). B) the challenge of preserving certain areas that constitute an ecological network in “not Japanese” for the associated species (e.g. ponds and lakes, ponds, peatlands) or certain areas not connected today but which can serve tomorrow as a “relay” or a new point of the ecological mesh of the territory (faced with changes such as climate change, the evolution of the range, fires, the disappearance of reservoirs via a development project...). Seizure scale: 1/100.000th.本数据集收录了中央-卢瓦尔河谷大区（Centre-Val de Loire）SRCE范围内酸性土壤上的亚框架草坪与干湿石楠灌丛的各类潜在生态廊道。 此类廊道可实现生物多样性储库之间的连通，为物种迁徙及完成生命周期提供适宜条件。（依据《环境法典》第R.317-19条第三款）。根据CERS规则，可实施两级干预措施：需修复的廊道与需保护的廊道。应在廊道轴线两侧各预留3公里的指示性通行带，以表明此类廊道属于非精确的迁徙主轴范围，需结合本地实地知识进一步细化完善。 本数据集为SRCE的派生成果。法规允许并非所有生物多样性储库都必须通过生态廊道实现连通（依据《环境法典》第R.317-19条第二款）。该连通场景应受到严格限制，且仅适用于以下情形的生物多样性储库： 其一，考量连通或维持这些空间自然隔离状态的合理性，具体包括：为防止外来入侵物种扩散，或规避野生动物携带可传染给家畜（如猪瘟）乃至人类（如狂犬病）的病原体所引发的潜在健康风险而采取的隔离措施； 其二，保护部分区域的必要性，这些区域构成了对关联物种而言属于"非日本型"的生态网络（例如池塘、湖泊、泥炭地等），或是当前尚未连通但未来可作为区域生态网络"中继节点"或新增节点的区域（需应对气候变化、物种分布范围变迁、火灾、开发项目导致的生物多样性储库消失等多重变化）。 制图比例尺：1/100000。
