The Audubon Society of Portland is a non-profit environmental organization dedicated to wildlife conservancy in Portland, Oregon, United States. Founded in 1902 and incorporated in 1909, it is one of the oldest such organizations in the world. It is named in honor of John James Audubon, an ornithologist and naturalist who painted, cataloged, and described birds of North America in Birds of America published in sections between 1827 and 1838. The society owns 150 acres (0.61 km2) of woodland adjacent to Forest Park, managed as a nature sanctuary and features indigenous vegetation and fauna, including a small stand of old growth timber. The sanctuary is open to the public for free. Much of the sanctuary surrounds Balch Creek near its headwaters and contains more than 4.5 miles (7.2 km) of hiking trails which connect to Forest Park's extensive trail system. More information...
