My wife farms high-intensity vegetables and a friend keeps 8 or 9 hives on our place at all times. We don't need the bees for our farming since we have so many wild bees, but the hives make more honey for them than anywhere else they keep hives so we cannot see any good reason not to let them keep their hives of non-native honey bees on our land. European honey bees may compete with the native bees a little, but I think they do minimal harm (hopefully not spreading disease to the native bumble bees which has been a problem in some places). Of course we know how to use insecticides according to the label and almost all herbicides are not toxic to bees (so the concentrated livestock bees are pretty safe). If you do use insecticides, follow label directions and don't think that organic insecticides are safe to bees because many are very toxic to beneficials and need to be treated like any other pesticide (not used on flowering plants during pollination times). We are restoring a large chunk of our land to wildlife habitat so herbicides are critical in controlling invasive plants. Sounds like we have similar interests but may approach the situation differently.
