Snowshoe hares have become more prevalent on Prince Edward Island following post-tropical storm Fiona, according to a wildlife biologist from the province. Garry Gregory, working with P.E.I.’s fish and wildlife division, mentioned an increase in sightings of “rabbits” by Islanders. However, these animals are actually snowshoe hares, as rabbits are not indigenous to the area. While there is no official data tracking the growth of the snowshoe hare population, Gregory indicated that the altered landscape post-Fiona likely contributed to their increase.
The aftermath of the 2022 storm left behind dense forest debris, creating ideal hiding spots for hares. This cover provided protection against predators, leading to a potential rise in the hare population. As the debris breaks down over time, the advantage for hares will diminish. The new growth resulting from Fiona, including shade-intolerant plants like willows and birch, offers essential winter forage for snowshoe hares and benefits other wildlife species.
Gregory highlighted that the increase in hares does not necessarily indicate a spike in predator numbers on the island. While predator populations in northern Canada are closely tied to snowshoe hare cycles, P.E.I. predators are more generalist in their diet. He advised Islanders encountering hares in their yards to refrain from feeding them, as it can attract unwanted attention from predators and pose risks to the hares.
In addition, Gregory addressed concerns about ticks found on hares, stating that the tick species commonly seen on hares are not the primary carriers of Lyme disease. Observing ticks on hares is a normal occurrence and typically does not pose significant health threats unless the infestation is severe.
