Also, knowing somebody who runs a nature reserve, I also know their opinion about encouraging 'traffic' to their site, other than bona fide walkers, wildlife group members and wildlife or conservation volunteers. One or two hives might be okay, but an organised teaching apiary isn't likely to be small. It needs vehicle access, to service the hives, and might even need a flat surface for those with mobility issues. As a minimum it's likely to have a well worn path or track to it. All this means it will attract attention, and possibly the wrong sort of attention, with a knock-on effect on the rest of the site and for the local wildlife - which is the reserve's job to protect.
