Human activities have largely replaced any natural disturbances as the main influence on the Acadian forest, with dramatic effects on the landscape.
Forest clearing to harvest trees and convert land has had a widespread impact on the forests of the region. Forest harvesting techniques, including clear-cutting, have replaced most of the mature Acadian forest with younger forests that are often evenly aged and contain different and fewer species. Less than 5% of pre-settlement Acadian forest exists today, leading to the designation of critically endangered status by the World Wildlife Fund. While forest is the dominant land cover in the Nashwaak Watershed (92.5%), only a small percentage of this is mature forest (3.63%).
