In a proactive move to safeguard Alberta’s aquatic ecosystems, specially trained dogs are assisting in the fight against invasive mussels, which have wreaked havoc across the Great Lakes and other Canadian waterways since the 1980s. The province has yet to see these harmful species infiltrate its waters, but the recent establishment of golden mussels in California underscores the urgency of preventative measures. Through the dedicated efforts of these canine companions, Alberta aims to keep its waters pristine and its aquatic life thriving.
A Unique Partnership
The Aquatic Invasive Species Operations and Conservation Canine Program in Alberta has taken an innovative approach by incorporating canine capabilities into its inspection protocol. Since its initiation in 2013, the programme has expanded to include these remarkable dogs—Hilo, Jane, and Winnie—who are trained to detect the distinctive scents of invasive mussels. As Cindy Sawchuk, the programme’s lead, explains, these mussels are adept at hiding in dark, damp spaces, making them difficult for human inspectors to spot.
“The dogs really enhance our inspections, providing a deeper insight into what could be lurking on a boat,” Ms. Sawchuk remarked. With their keen sense of smell, these intelligent canines complement human efforts, ensuring a more thorough examination of vessels entering the province.
The Threat of Invasive Mussels
Invasive species such as zebra and quagga mussels, originally from Eastern Europe and Southeast Asia, pose a significant threat to local ecosystems. These filter feeders may seem innocuous, but they can quickly monopolise food resources, adversely affecting native fish populations, particularly larger species. The introduction of these mussels could lead to a dramatic decline in biodiversity within Alberta’s lakes.
Since 2015, the province has operated 11 inspection stations, where teams of humans and dogs work in tandem. While inspectors physically examine boats, feeling for the rough texture of developing mussels, the dogs focus on identifying their unique odour. When a dog successfully detects a scent, they are rewarded with a cherished toy, turning the search into an engaging game.
Dogs of Distinction
The current canine team consists of Hilo, a black Labrador known for his thoughtful and methodical approach to searches, as well as two newcomers, Jane and Winnie. Hilo, affectionately dubbed “The Professor,” transitioned from a guide dog school in California to become a vital part of this programme. Jane and Winnie, both rescued from shelters—one from Mexico—are the latest additions to this elite unit.
A fourth dog, Diesel, serves in a supervisory capacity, providing guidance to the new recruits. Ms. Sawchuk notes the rarity of dogs suitable for this line of work, revealing that fewer than one in 1,000 possess the necessary drive and aptitude. Once trained, these canines can effectively search shorelines, docks, and boats, honing their skills through practice scenarios where mussels are deliberately concealed.
Building Bonds
The relationship between the dogs and their human partners is crucial for success. Ms. Sawchuk emphasises the importance of trust and communication, stating, “We really want that bond. It’s about building a relationship where the dog feels comfortable to alert us.” This connection is vital for recognising subtle cues from the dogs that indicate the presence of hidden mussels. Hilo’s past experiences, including his training sessions in Texas where he discovered mussels in tall reeds, further underscore the need for this close-knit partnership.
Why it Matters
The integration of canine detection into Alberta’s invasive species prevention strategies exemplifies an innovative approach to environmental conservation. As the threat of invasive mussels looms closer, the work of these dogs not only protects local ecosystems but also ensures the sustainability of Alberta’s natural resources. By prioritising proactive measures, the province sets a precedent for safeguarding aquatic life against future threats, highlighting the critical role that both human ingenuity and animal instincts play in environmental stewardship.
