ArborNote’s Tree of the Week is the White Pine (Pinus strobus). Its native range is from Newfoundland, Canada, west through the Great Lakes region to southeastern Minnesota, and south along the Appalachian Mountains and upper Piedmont to northernmost Georgia and very rare in some of the higher elevations in northeastern Alabama. Old white pines are treasured in the United States. An American National Natural Landmark, Cook Forest State Park in Pennsylvania, contains the tallest known tree in the Northeastern United States, a white pine named Longfellow Pine. Some white pines in Wisconsin are over 200 years old. The Haudenosaunee (also known as the Six Nations) maintain the tree as the central symbol of their multinational confederation, calling it the “Tree of Peace”. Since 2017, it has appeared on the flag and seal of the city of Montreal to represent the indigenous peoples of the area.
