Potential wetlands (Couesnon watershed, 2016-2017) - Zone Atelier Armorique ZAAr

This map represents potential wetlands of the Couesnon watershed bottom valley at 1 : 25 000.

Potential wetlands correspond to the largest area that wetlands would represent without human activity and are characterized by a hydromorphic soil (Mérot et al., 2006).

A LiDAR-derived DTM (from IGN) and 107 soil samples were used to estimate an elevation threshold between hydromorphic and non-hydromorphic soil, according to the nearest stream Strahler order (Rapinel et al, 2017).
