The Corson Natural Area is 160 acres of bottomland just north of Lake Stevens in a rural residential area. It was last logged and cleared in the 1950s. The previous owner, who gave it to WDFW in 1976 for wildlife habitat enhancement and non-hunting public use, built a one-acre and an eight-acre pond, and maintained about seven acres of clearings, which are still present today. The remainder is second growth forest of mixed deciduous/coniferous tree with red alder. Catherine Creek cuts through the northeastern corner. In the last 15 years, volunteer groups have cleared the alder trees and brush to plant about eight acres of coniferous trees. A contract farmer planted the seven-acre agricultural field in barley for wildlife use. There is a trail, one observation blind, but no developed public access.
