We are excited about hosting a wild bee nesting box in our new garden as a part of a study on wild bee populations in urban habitats that is being conducted by Scott McIvor through the Packer Collection (PCYU) at York University. You can see how the nestboxes are constructed here.
We can’t wait to see if any bees take up residence in the little paper cells. In his enthusiasm, Davin started checking hours after the PVC box was installed. Needless to say there are no bees yet but I did see one resting on our compost bin and another came out of a hole in the ground as I was digging up sod. We are also curious to see how general insect populations change as we introduce more diversity to what is currently a plantless yard.
Scott is also tracking cavity nesting bee populations on green roofs. If you have a green roof and would like to be involved you can get in touch via TO Bees.
