SAVING MARION ISLAND’S SEABIRDS: THE MOUSE-FREE MARION PROJECT
Saving Marion Island’s seabirds is a bold, science- driven effort to restore a fragile ecosystem by removing invasive house mice. Introduced in the early 1800s, the mice now prey on seabird chicks—and even adults—putting 19 of 29 species at risk of local extinction within 30 years. A proven solution is in place: GPS-guided helicopters will distribute rodenticide across the island in a one-time operation to eliminate mice and enable seabird recovery.
Funds raised through 2025 guest auctions aboard Quark Expeditions’ voyages supported essential field trials—from tracking tunnels to remote cameras. Combined with AI image analysis, these tools refine baiting strategies and help ensure a safe, effective eradication.
