The Syndicat mixte du Conservatoire Botanique National des Pyrénées et de Midi-Pyrénées has been working for 20 years to encourage the consideration of threatened flora. As such, the National Botanical Conservatory of the Pyrenees and Midi-Pyrénées proposes through this project entitled “Program for the management of sub-trames to reconcile human activities with the preservation of plant diversity” a programme to support local stakeholders in order to better take biodiversity into account. Thus, this project aims to continue the momentum launched in previous operations by proposing new awareness-raising and information actions. The actions are targeted by major types of environment (sub-trames of urban environments, sub-trames open and semi-open, sub-trapes rocky environments) and aim to promote a shared approach to the issues of flora and habitats in order to better reconcile human activities with the preservation of biodiversity.
