Method for the rapid assessment and potential mitigation of the environmental effects of development actions in riparian zone.

Watershed and river managers often face difficult choices between safety issues related to floods and degraded hydraulic structures, requiring urgent works and involving environmental stakes such as biodiversity, landscapes and rare species. These choices require taking precise ecological data and existing knowledge into account. Unfortunately, such databases and pre-existing knowledge are rarely available or they are only fragmentary and exist at the local scale for parts of areas classified as protected, or they are limited to a few species.
