The City of Vancouver released their Biodiversity Strategy recently. The goal of the strategy is to restore or enhance 25 ha of natural areas by 2020. The project is ambitious! It targets both aquatic and terrestrial ecosystems, and organisms from invertebrates, to birds, to mammals. There's a section of the report on native bees, and how they propose to increase habitat for these species. I'm not sure how it's all going to happen in 4 years. They'll need to have some baseline information on species richness and population sizes; they'll need to pick where and how to restore/improve habitat, and then they'll need to repeatedly census populations again to see if their efforts actually worked. It'll certainly be all hands on deck for this project. Fingers crossed.
