Riparian corridor

Schéma d'un corridor
Sens technique

Strip of natural vegetation located along a river, and which differs from the surrounding matrix, including the river bank, the floodplain and part of the alluvial terraces. The presence of a stream or wood is not enough to make corridors. It is their conduction function that defines them. At the regional level, the riparian corridor appears to be a relatively uniform area (line of trees). At the local level, sedimentary and hydrological constraints provide variability of conditions resulting in a mosaic of habitats. The corridor is a transition zone between the water system and terrestrial system. Thus, biodiversity is extremely rich: productivity (plant and animal), heterogeneity (from the structure of the vegetation - grass, shrub, tree - to the habitat diversity), dynamic (flooding, regeneration capacity, etc) connection (upstream-downstream, lateral, regional) are the key words that define the riparian corridor.
