Wild pollinators in the France-Wallonia-Vlaanderen cross-border zone represent a valuable but highly endangered resource. In order to protect these pollinators, it is essential to set up a cross-border organization that enables coordinated actions and synergies between regions. Indeed, isolated actions on both sides of the border are unlikely to lead to the sustainable management of this indispensable resource. The challenge is huge because wild pollinators, wild bees, syrphs and butterflies, are essential to maintaining agriculture and ecosystems in our regions. In order to meet this challenge, the SAPOLL project initiates the implementation of a cross-border action plan for wild pollinators with the actors from Wallonia, Flanders and northern France. This plan is the initiator of actions in favor of pollinators, bringing the necessary scientific, didactic and applied context to citizens, decision-makers, entrepreneurs or enrionmental managers. It is also adapted to the regional context of each area. The action plan, which is co-built with the partners in the cross-border territory. The SAPOLL project also organizes activities that aim to homogenize and share scientific knowledge, awareness-raising experience and naturalistic competences
