Mountain farmers from five alpine regions in Europe were interviewed to understand their views on grassland biodiversity and management. They described good grasslands based on quality, productivity, soil, and topography. Farmers suggested ways to boost biodiversity like planting trees, less cutting, and fewer fertilizers. Challenges like extra work and costs could hinder these efforts. Farmers have varied knowledge on biodiversity management, and different ideas on how to enhance it. Collaborations between farmers and biodiversity experts could help improve grassland biodiversity practices in the future.
