Continuity framework for semi-aquatic mammals in Brittany and Loire-Atlantique

Mean value of ecological continuity of 2 semi-aquattic species (Loutre d’Europe and Campagnol amphibia) in Brittany and Loire-Atlantique continental. These values, distributed from 1 to 100 in this diffuse frame, synthesise the quality and quantity of possible connections between the habitat cores of protected semi-aquatic mammals.
This data is an element of the “Trame Mammiferères de Bretagne” (TMB) tool designed to enable the integration of the ecological continuity of mammals into the Green and Blue Trames and take them into account in all public policies, spatial planning, projects and actions likely to affect these species or their habitats.
See Notice de la Trame Mammiferères de Bretagne (GMB, 2020) for more details.
