Data-driven recovery of at-risk bumblebee species: pinpointing optimal release and recovery sites across Ontario

This project will help protect at-risk bumble bee species in Ontario by identifying the best places to release captive-reared queens back into the wild. Bumble bees are essential pollinators, but many species are declining due to habitat loss and environmental change. While Wildlife Preservation Canada (WPC) has successfully reared several native species, choosing safe and suitable release sites remains a major challenge.

To address this, we will analyze eight years of queen bumble bee survey data collected across Ontario by WPC, combined with environmental information such as land cover, soil conditions, elevation, and vegetation. Using modern geospatial tools and habitat-suitability modelling, we will create detailed maps that show where conditions are most favourable for bumble bee survival and nest establishment. These maps will be tailored to individual species, highlighting the distinct environmental features that support each species needs early in the season when nests are founded.

The results will directly support conservation planning by helping practitioners focus resources on high-quality habitats, improving the success of reintroduction efforts, and contributing to the long-term recovery of native pollinators in Canada.
