Snowshoe hares have become more prevalent on Prince Edward Island following the aftermath of post-tropical storm Fiona, according to a wildlife biologist in the province. Garry Gregory from P.E.I.’s fish and wildlife division mentioned an increase in sightings of what some Islanders initially mistook for rabbits in their yards. However, these animals are actually snowshoe hares, as rabbits are not native to the region. Gregory explained that while it is challenging to determine if the hare population has surged, the altered landscape post-Fiona likely supports such a theory.
The storm left behind dense debris in forests and woodlots across P.E.I., creating ideal escape cover for hares with brush piles, downed trees, and thick patches of deadfall. This newfound hiding spots have contributed to the survival and potential increase in the hare population. As the debris gradually breaks down and coniferous trees shed their needles, the advantage hares gained post-storm will diminish.
The storm not only provided cover for hares but also opened up the forest canopy to sunlight, allowing early successional, shade-intolerant plants to flourish – a key food source for hares during winter. Gregory highlighted plant species like willows, grey birch, maples, and pin cherry as essential winter forage for the hares. This new habitat also benefits other wildlife species such as songbirds and woodcock.
While the rise in hares may cause concern about potential predator increases, Gregory assured that on P.E.I., predators are generalists and not solely reliant on snowshoe hares as a food source. He emphasized that feeding hares is unnecessary and could lead to unintended consequences like attracting them closer to dogs.
Furthermore, Gregory addressed the issue of ticks on hares, explaining that the tick species commonly found on hares are not the ones associated with Lyme disease. The presence of ticks on hares is normal and typically does not pose significant health risks unless the infestation is severe.
