A specially trained Labrador retriever named Tilly is helping conservationists detect invasive species threatening local ecosystems across Toronto's region.
Credit Valley Conservation uses dogs like Tilly to sniff out invaders that humans can easily miss. Tilly's nose is powerful enough to detect the presence of invasive species before they spread and cause irreversible damage to native habitats.
The program pairs dogs with trainers who work with conservation experts to monitor critical areas. As invasive species — from plants to animals — become an increasingly serious threat to Ontario's natural systems, these canine teams offer a low-impact, effective detection method.
The work is part of a broader regional effort to protect local ecosystems. Grand Council Treaty 3 has ramped up zebra mussel monitoring as aquatic invasive threats grow, and other organizations across Ontario are grappling with species like American bullfrogs that establish themselves quickly and outcompete native wildlife.
