Species of maple

Acer macrophyllum, the bigleaf maple or Oregon maple, is a large deciduous tree in the genus Acer. It is native to western North America. In addition to uses by animals, it is of some culinary and woodworking interest.

Bigleaf maple can grow up to 158 feet (48 m) tall, but more commonly reaches tall and The species' current national champion for size is located in Lane County, Oregon. It is 119 feet (36 m) tall with a crown spread of 91 feet (28 m), with an average diameter at breast height (dbh) of about The previous national champion is located in Marion, Oregon, and is 88 feet (27 m) tall with a crown spread of 104 feet (32 m), with an average dbh of about The bark is gray brown, darkening and developing ridges with age.

The fallen leaves, blossoms, and seeds are concentrated with potassium, calcium, and other nutrients. It usually grows from sea level to elevations of , and more exceptionally Though very rare north of Vancouver Island, it is cultivated in Prince Rupert, near Ketchikan, and in Juneau.

Native Americans grew sprouts from the seeds for consumption, wove baskets from the inner bark, and used the leaves to cover food in cooking pits. They also carved the wood into dishes, utensils, and canoe paddles. Maple syrup has been made from the sap of bigleaf maple trees. While the sugar concentration is about the same as in Acer saccharum (sugar maple), the flavor is somewhat different. Interest in commercially producing syrup from bigleaf maple sap has been limited. Although not traditionally used for syrup production, it takes about 40 volumes of sap to produce 1 volume of maple syrup.

The bigleaf maple is the only commercially important maple of the Pacific Coast region.
