At the Netherlands Floriade exhibition the planting was all bee friendly and there were huge numbers of bees. Even in every eating or seating place, as a beekeeper you were so aware. (And of the splendid dragonflies). Yet I think non beekeepers probably didn't notice. From about 4 pm (I assume after a day at school) huge numbers of coachloads of children arrived on school outings to the show. Perhaps we have been brain washed by 'elf and safety'? I daresay they had planned things really well and that is what we need to take away. If the hives are too close to a garden play area/ walkway and not forced to fly up the story could be different. In the area where some of the hives were based and the visitors could go round and scan either pollen or nectar, there was a sort of caged section so the whole exhibit (which included a small garden, walkways and a two story building like a giant hive) had a sort of net /small chain link rectangular tent around it. However, the visitors happily walked inside that as well as the acres/hectares of the whole exhibition. They probably had a reason for doing it that way - perhaps in case there was an unusual situation in which case they might be able to contain it. As we walked in, this netting formed an opening through two curtains that overlapped at the top. I wonder whether a bee proof barrier in some gardens could be useful? Most responsible beekeepers would then consider their neighbours as much as their own family. Trouble is we all know that when you highlight the fact you have bees every single bee, wasp or flying insect in the neighbourhood is seen as your responsibility.
