Usually associated with the Maritimes, Red Spruce grows in scattered locations in eastern Ontario, but populations can be locally abundant. They are sometimes confused with White Spruce (Picea alba), but careful scrutiny rewards the observer with the correct ID.
Red Spruce has been found on the eastern side of Ottawa out to Vankleek Hill, the Alfred Bog, and Hawkesbury, and in Gatineau Park, Quebec. Two isolated populations have been located west of Ottawa, one in Algonquin Park and the other at Rose Hill Nature Reserve. There are probably more to be discovered! The best site to view many 100+ year old Red Spruce is in the NCC Greenbelt at Anderson and Leitrim Road. Other good public sites include: Gatineau Park along the Wolf Trail particularly on the northern side of the loop and Lavigne Natural Park near Bourget.
