A medium/long term strategy (from 3 to 8 years) will be jointly developed based on the sharing of the results of our multi-stakeholder group animation work at transnational level. Its main objective will be to guide professionals (landscapers, consultants, public and private buyers, scientists, local development associations, site managers) and decision makers (elected representatives, company managers, etc.) towards the means of action available to them to support the long-term viability of the technical solutions tested during the project (collection, planting and monitoring of local indigenous herbaceous seeds, etc.). This strategy will define realistic objectives (taking into account the constraints of these stakeholders) but ambitious enough to support the development of the proposed solutions. It could be broken down into several action plans, tailored to each type of public concerned and their respective areas of competence. We will identify a number of economic and public policy levers that can support this strategy. To facilitate its implementation, the strategy will be accompanied by a number of resources available in open access: training modules for field workers and decision makers, awareness-raising content, a letter of engagement, feedback from multi-stakeholder groups, etc.
