Documentation of farmer-based biodiversity observation and monitoring activities between 2021 and 2024 in 11 FRAMEwork Farmer Clusters across Europe. The FRAMEwork project took a bottom-up and action-based research approach to developing biodiversity and ecosystem services (ES) observation and monitoring activities with farmers in 11 Farmer Clusters (FCs) across nine European countries. This approach was chosen to cater directly to the real-world context of the farmers, as well as their interests and needs in terms of biodiversity and ES. In total, about 70 events and activities were organised between autumn 2021 and 2024 across the 11 FCs, with more than 1,000 attendances of farmers and other local participants. This document contains a full documentation of these activities via activity briefs.
