The restoration works of small (1-3 ha) forest meadows along a small river have been started. Are there any studies on the distance from which insects fly to forest meadows to feed or reproduce? Does the size of these meadows matter?
I am not an entomologist; I have only some insight into bee-keepers´ life and work. A mobile apiary placed on different sites around meadows and fields reveals by the resultant sort of honey produced during a certain season that your size in terms of hectares is fully within the flying range of the flower-oriented insects.
I hope I come close to an answer to your question (?)
It's a very good question. Forest making or re-establishment is a good science both in terms of biodiversity conservation and society benefits... invertebrates always the key for soil manuring
