The way we protect it is that all farmers can report a Grutto nest on their land. Then the government sends volunteers to find the nest. If the volunteer finds the nest, the farmer gets 1200 euro.
It's a simple scheme but I think it's very effective. It's a significant amount of money, the farmer will be looking out for the nests, and will make sure they don't get caught in their machinery.
I'm not entirely sure what the economics would be for bee hives. 1200 euro to put some stakes in the ground and make a small detour with your tractor, sacrificing maybe 10m2 of harvest makes sense. Not treating an entire field with insecticides might not.
