Following post-tropical storm Fiona, a noticeable rise in snowshoe hares has been observed on Prince Edward Island, according to a provincial wildlife biologist. Garry Gregory from P.E.I.’s fish and wildlife division stated that Islanders are reporting increased sightings of what they initially mistake for rabbits, although rabbits are not indigenous to the area. Gregory clarified that these sightings are likely snowshoe hares, a common occurrence in yards and properties.
While there is no official data tracking the surge in the snowshoe hare population, Gregory suggested that alterations in the landscape post-Fiona make it plausible that their numbers have grown. The storm left behind dense debris in forests across P.E.I., creating ideal escape cover for hares. This cover, consisting of brush piles and fallen trees, has facilitated the survival of more hares, potentially leading to a population increase.
The aftermath of Fiona has also resulted in new growth, benefiting snowshoe hares in terms of winter forage availability. The storm’s impact on the forest canopy allowed early successional plants to flourish, providing necessary food sources for hares such as willows, grey birch, and maples. This habitat transformation has not only benefitted hares but also other wildlife species like songbirds and game birds.
Despite the rise in snowshoe hares, Gregory highlighted that it does not necessarily equate to an increase in predators on the island. Unlike northern regions of Canada where predator populations are closely tied to hare cycles, P.E.I. predators are generalists with diverse diets, including snowshoe hares.
For Islanders encountering hares in their yards, Gregory advised against feeding them, as it is unnecessary and could attract them closer to potential threats like dogs. Additionally, he addressed concerns about ticks on hares, emphasizing that the tick species commonly found on hares are not associated with Lyme disease and generally pose no significant health risks unless the infestation is severe.
