Pine Martens (Martes martes) are native to Ireland and can be found in various habitats, including woodlands, forests, and rural areas. They are protected in Ireland by both national and international legislation. The habitats they are particularly associated with are mixed woodlands that provide both suitable den sites and access to their primary food sources. Den sites can include rock crevices, tree cavities, subterranean burrows, buildings (abandoned or occupied), old bird nests, squirrel dreys and log piles. Pine Martens play a vital role in maintaining the ecosystem’s balance by helping control pest populations by preying on rodents.
Pine Martens sometimes use tree cavities, rock crevices, and occasionally abandoned buildings as dens. During construction projects, it’s essential to conduct ecological assessments to determine if Pine Martens are present. If they are, measures should be taken to avoid disturbing their dens and habitats, ensuring their protection.
