资源简介:

An inventoried Frayère brings together the concepts of fish spawning grounds and crustaceans growing zone or feeding areas as defined in Article L.432-3 of the Environmental Code. Article L.432-3 of the Environmental Code defines fish spawning grounds as: — Any part of a watercourse which is included in an inventory established pursuant to Article I of Article R. 432-1-1 and whose bed consists of a mineral substrate having the characteristics of the size specific to the reproduction of one of the fish species included in the first list provided for in Article R. 432-1, — or any part of watercourses included in an inventory established pursuant to Article R. 432-1-1 II. A crustacean growing or feeding zone within the meaning of Article L. 432-3 corresponds to any part of watercourses included in an inventory established pursuant to III of Article R. 432-1-1. The founding regulatory text of the inventoried Frayère is the decree issued by the Prefect of Department. Two types of stream parts may be demarcated. Parts of “classical” watercourses delimited from the BD Carthage® hydrographic network. Parts of “out-of-grid” rivers BD Carthage®. The affluent and sub- tributary attributes add a level of detail to compensate for the lack of completeness of the hydrographic reference used. “Flow” means the consideration of first-level tributaries adjoining the demarcated part of watercourses. “sub tributary” means the consideration of watersheds adjacent to the demarcated part of watercourses.

已登记的Frayère涵盖了《环境法典》第L.432-3条所定义的鱼类产卵场与甲壳类动物生长区、觅食区的概念。 《环境法典》第L.432-3条将鱼类产卵场定义为:—— 属于依据《环境法典》第R.432-1-1条第I款编制的名录范围内的水域区段,且其河床由符合《环境法典》第R.432-1条所规定的首批名录中某一鱼类物种繁殖所需特定粒径特征的矿物基质构成;—— 或属于依据《环境法典》第R.432-1-1条第II款编制的名录范围内的水域区段。 《环境法典》第L.432-3条所指的甲壳类动物生长区或觅食区,则对应属于依据《环境法典》第R.432-1-1条第III款编制的名录范围内的水域区段。 已登记的Frayère的设立依据为各省省长发布的政令。 可划定两类水域区段:一是从BD Carthage®水文网络中提取的“常规”水域区段;二是BD Carthage®水文网络未覆盖的“网格外”河流区段。 支流与次级支流属性可补充细节层级,以弥补所采用的水文参考资料的完整性不足问题。 “一级支流(Flow)”指需考量与划定水域区段毗邻的一级支流;“次级支流(sub-tributary)”指需考量与划定水域区段相邻的流域范围。
