The politics of sustainable development encourage the creation of structures that produce renewable energy. In Aveyron, wind turbines have developed which in turn has created a mortality risk for the populations of large raptors found here. Many cases of death caused by wind farms have been recorded by local environmental organisations, mainly due to collisions. One of the objectives of this project is to reduce the threat posed by wind turbines, and particularly by wind farms, by applying regular and rigourours monitoring throughout the area concerned. Each turbine that has been proven to have been the cause of death of a large raptor is subject to a report written by LPO Grands Causses (to which structures?). LPO Grands Causses remains vigilant regarding the development of new wind farm projects on its territory. GPS trakers which allow precise monitoring of movements have been placed on bearded vultures and some cinereous vultures and providing precise data to allow territory mapping. Such information is vital for LPO Grands Causses to provide the necessary information to state and territorial bodies to take informed decisions on the emplacement of powerlines.
