I work on a Plan Bee project for Lancashire Wildlife Trust and have been asked by a local group if placing up to twenty bee hives on a Nature Reserve (that includes small areas of semi natural and created, fairly species rich grassland) will have a detrimental effect on other pollinators.
The location is Chorley, in central Lancashire.
I've wondered about this myself on a number of occasions though have not been able to unearth any scientific study or even anecdotal reports.
I guess the first instance would be to avoid hives in areas known to have rare / declining species of aculeates, though this is fairly lowland Lancashire and there are no rare bees recorded - there are very few uncommon - rare bees in Lancs at all other than Bombus monticola, Colletes cunicularius and Osmia parietina - and none of these are recorded even near to here.
Any studies / reports / personal observations relating to Bumblebees and any other pollinators would be much appreciated.
This is particularly timely with the National Pollinator Strategy from England punted - I expect to be grilled on this quite a bit in future.
Cheers in advance,
