Degradation of agricultural landscapes
The current intensification of agricultural practices is a major cause of habitat degradation and biodiversity loss. These effects are particularly strong in Reptiles and Amphibians, which are characterized by low mobility and dependence on specific environments. We have launched a “Bocage & biodiversity” programme in the Deux Sèvres in collaboration with the ONCFS and a network of farmers. Our work highlights the positive relationship between a preserved bocage landscape (networks of hedges, ponds and small woodlands) and the specific richness of reptiles and amphibians. The presence of species obtained by modelling is modelled on the bocage landscape of the Deux Sèvres. We have also demonstrated the importance of the quality of the microhabitats: hedge structure and breeding ponds. Maintaining landscapes that are compatible with biodiversity requires action at the farm level.
