As part of the implementation of the third management plan (validated in October 2018) of the Allier Valley NDN by the Senior Manager: the LPO Auvergne-Rhône-Alpes. In order to ensure the continuity of part of the actions undertaken in 2018 and improve knowledge of the natural heritage, the LPO Auvergne-Rhône-Alpes proposes: — to make investments to equip the reserve with agricultural equipment enabling the maintenance of grazing and the sustainable development of agricultural practices while ensuring the preservation of habitats of European interest; — to ensure the reproduction of certain species of birds susceptible to disturbances by informing the public, the establishment of a quiet and monitoring area; — to establish scientific monitoring and studies to assess the conservation status of certain habitats, to gain a better understanding of the diversity of certain faunistic groups considered to be bioindicators (hymenoptera, fish...) and to understand the natural dynamics of certain particularly rare habitats at European level; — to value this site in order to allow good territorial integration (requested by all stakeholders) and to promote its discovery by different audiences including the local population who do not really know it (poster, flyers, leaflet) The operation concerns the implementation of the actions between 2019 and 2021.
