I would imagine that if the RSPB advocated catching and killing birds in their analogous annual bird watch there'd be an almighty outcry!
Birds are not wasps - I am sure you are aware of that - you cant just compare between the two.
Monitoring without killing isn't positive? Okay.
You haven't offered an alternative method. "Taking Photos" isn't enough detail to compare with the plan in place.
Ahhh! That sounds like some of the monopolistic speak I hear from Unis.
Thank you for your kind words - though I am not sure how asking for you better method of collecting this data is "monopolistic", I would say it is the opposite. Maybe research the words you use before typing them?
