The Acer macrophyllum, commonly known as the bigleaf maple, is a species of maple tree that is native to the Pacific coast of North America. This deciduous tree is known for its striking appearance, with large, lobed leaves that can grow up to 12 inches in diameter, making it one of the most recognizable and iconic trees in the region. The bigleaf maple is not only an important part of the ecosystem, providing food and habitat for a variety of wildlife, but it also has significant cultural and historical importance, with many indigenous communities relying on the tree for food, medicine, and spiritual practices.
The Acer macrophyllum is a relatively large tree, typically growing to be between 50-100 feet tall, with a broad, rounded crown and a straight, columnar trunk. The tree's bark is gray and smooth, becoming increasingly rugged and fissured with age. The leaves of the bigleaf maple are its most distinctive feature, with 5-7 lobes that are deeply toothed and have a soft, hairy texture. The leaves are a bright green color on top and a pale yellow-green on the bottom, turning a brilliant yellow or orange in the fall. The tree produces small, yellowish-green flowers in the spring, which are followed by samaras, or winged seeds, that are an important food source for many animals.
