Forest Cover Trends in New England Since European Settlement I want to provide a quick and dirty example of the value of HRV for assessing long-term changes in New England. If we look at the history of forest change since European Settlement, long-term reforestation and recovery has been strongly influenced by the history of clearing and agriculture in the 19th century, white pine colonization and subsequent clearcutting, the loss of Chestnut and Elm, and commercial forest management practices favoring certain species and limiting or truncating stand development in the 20th century.
