Mark S. Burnham Provincial Park, located on the southeastern outskirts of the City of Peterborough, has often been cited as a fine example of “old growth forest” (Ontario's Old-growth Forests, Henry and Quinby 2010). See AFER's field report.
Numerous trees in the park have many of the external features of old growth trees, including balding bark, low stem taper, and broken crowns (see photo). In 2012, eleven trees exhibiting these characteristics were cored by NHIC staff members using an increment borer. The oldest trees were aged at a minimum 208, 235 and 330 years old.
