The territories of the SUDOE space are home to exceptional biodiversity, but the acceleration of the consequences of global warming, together with the intensification of human activities in some cases, and the abandonment of territories associated with the depopulating process in others, are causing the degradation and fragmentation of ecosystems. In this context, the challenge of the Flore project is to demonstrate the economic and organizational viability of the large-scale implementation of a package of ecological restoration solutions based on the exploitation of a local resource such as wild and native herbaceous seeds. To do this, first, practical tools adapted to the current needs of the target groups (administrations, companies, prescribers, owners, managers…) will be designed based on the lessons learned in previous projects. A network of demonstration sites will then be established in environments with different challenges, to show different solutions (including at least 3 ecological restoration modalities and different seed multiplication sites). In parallel, a multi-stakeholder participatory process will be led to design and test new models of economic cooperation aimed at the self-production of seeds by users or the supply of products and services to third parties according to a common catalogue. Public authorities and companies wishing to introduce local herbaceous seeds into their catering processes will also be accompanied, and public awareness days will be organised. The planned actions will also contribute to preserving the quality of life and the development of rural areas. The consortium consists of 8 partners (3 in France, 3 in Spain and 2 in Portugal). The pilots are located in Occitania, Auvergne, Extremadura, Soria, Murcia, Serra da Estrela and on the left bank of the Guadiana River. Transnational cooperation will allow adapting the range of restoration solutions proposed to the normative contexts of each country and to the realities of each territory, affecting the diversity of representative environments of the SUDOE space.
