Wolverine ID card:


Wolverine: When traveling, wolverines tracks usually display a characteristic 2×2 or 3×3 pattern. While wolverine tracks can be found in the valley bottom and in forests, they are often encountered high up above tree-line, where they are visible from far. Wolverines usually travel in a straight line, sometimes for kilometers, as if they are on a mission!


American (pine) marten: Marten are much smaller than wolverine, but have a similar 2×2 pattern. A marten only measures about 0.5 – 0.7 m (1.5 to 2.2 feet) (including tail), and their paws are small, 3.5 – 4 cm long (~1.5 inch).

 


Canadian lynx: Lynx tracks are of a similar size than wolverines, but they don’t  show the 5th toe, and their claws are, like with all cats, usually retracted when they walk. They also usually walk in a more undulating way than wolverine, and the distance between paw prints is very regular.


Porcupine: These rodents have a very characteristic gait, and usually drag their tails. In deep snow, porcupines can leave hard-to-identify tracks. Sometimes, porcupine dens are reported as wolverine dens. We ourselves have been fooled, before, too!
