One glaring problem I see with this is that anyone who has ever had hives (which my family has) knows how quickly Varroa mites can spread (the #1 killer of bees.) If all the bees are in a single location, that could wipe out every hive there. Would make more sense to me if you made sanctuaries that were spread on ~1 acre plots around a wide area (thinking several cities/town in a clustered area.)

Anyone with more expertise is free to correct me, but I feel like clustering bees on single plots, even 124 acres (which seems big, but is not really that big,) really has some risk if your end goal is to preserve the species.
