Name: EQ Biologie des masses d'eau rivières (évaluation EDL 2025 données 2021 - 2023)

Display Field: code_me_eu

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: Pour les cours d’eau, les éléments de qualité biologique à prendre en compte pour l’évaluation de l’état écologique sont : ▪▪ la flore aquatique ; ▪▪ la faune benthique invertébrée ; ▪▪ l’ichtyofaune. Dans le cadre de la DCE, l’élément de qualité biologique flore aquatique comprend les macrophytes, le phytobenthos (diatomées) et le phytoplancton pour les très grands cours d’eau. Dans le cadre des règles d’évaluation nationale de l’état écologique des eaux, macrophytes et phytobenthos sont considérés comme deux éléments de qualité biologique distincts.
