Invasive species can quickly decimate the native species of a region, but getting rid of the invaders can be challenging. In Hawai’i, the wolf snail has been linked to the decline and even the extinction of many species of snail that are endemic to (only occur in) Hawai’i. Wolf snails are on the top 100 “World’s Worst” invaders list, and eradicating them in our 50th state is a high priority among conservation groups. So, what’s the latest method for finding these wolf snails? Detection dogs, of course!
Canine-human teams, trained in their home region of Montana to the scent of the wolf snail, headed to Hawai’i for four weeks of work and troubleshooting with researchers. Picking up the scent of these snails in a wet tropical region proved challenging and this initial foray served to provide information they will use to design additional training techniques back in Montana and design the best system for detecting the snails.
While dogs are well known for their ability to sniff out everything from bed bugs  and illegal DVDs  to criminals carrying cash and peanuts , it is not well known that every type of successful detection work requires creative thinking in every aspect of the process from training the dogs to the specifics of the search strategies. Each new challenge requires lots of work, patience, and sometimes even multiple trips to Hawai’i! Let’s hope these dogs and their humans are soon able to stop the spread of this snail before more precious species are lost forever.
