Should Flea Beetles Be Released to Control Invasive Weeds in Grasslands National Park?
Official title: Leafy Spurge Biological Control in Grasslands National Park
Parks Canada wants to release flea beetles in Grasslands National Park to eat leafy spurge, an invasive weed that's hard to kill with herbicides. The beetles only eat this one plant species. If it works, native prairie plants could recover and endangered species habitat would improve.
Why This Matters
This is a specialized conservation project in a remote Saskatchewan park. If you're passionate about prairie ecosystems or concerned about introducing new species to control invasive plants, this matters. For most Canadians, it's a technical park management decision.
What Could Change
Parks Canada would release Aphthona flea beetles in summer 2025. Staff will monitor whether the beetles successfully reduce leafy spurge and whether native plants return. This biological control approach could become a model for other parks dealing with invasive species.
Key Issues
- Is releasing flea beetles an effective way to control leafy spurge in the park?
- What monitoring should be done to track the beetles' impact on vegetation?
Indigenous Consultation
This consultation requires engagement with Indigenous communities under the Crown's duty to consult.
