Michigan State Tree

Eastern White Pine

Michigan State Tree: Eastern White Pine

(Pinaceae Pinus strobus)

Adopted on Oct. 14, 1955.

The eastern white pine, is also known as "soft pine."It was called the Tree of Peace by the Iroquois and in Ojibway, Zhingwaak. Mature white pines can easily live 200+ years of age, with some Michigan trees that have approached 500 years in age. The eastern white pine has the distinction of being the tallest tree in eastern North America, and pre-colonial stands were reported over 200ft in height.

The towering eastern white pine, (Pinaceae Pinus strobus,) is a symbol of one of Michigan's greatest industries--lumbering. From 1870 to the early 1900s, Michigan led the nation in lumber production. During those years a transportation network and communities grew across the state to accommodate the lumber boom. Public Act 7 of 1955 designated the white pine as Michigan state tree effective Oct. 14, 1955.

Pinus strobus, commonly known as the eastern white pine, white pine, northern white pine, Weymouth pine, and soft pine is a large pine native to eastern North America. It occurs from Newfoundland west through the Great Lakes region to southeastern Manitoba and Minnesota, and south along the Mississippi Basin and Appalachian Mountains to northernmost Georgia and Mississippi.

Eastern white pine is one of the most valuable trees in eastern North America. Before the arrival of white men, virgin stands contained an estimated 3.4 billion m? (600 billion fbm) of lumber. By the late 1800's most of those vast stands had been logged. Because it is among the more rapid growing northern forest conifers, it is an excellent tree for reforestation projects, landscaping, and Christmas trees and has the distinction of having been one of the more widely planted American trees.
