The Rock Creek Environmental Studies Center is a natural area within Portland Community College's Rock Creek Campus in Washington County.

The campus is located on about 250 acreas. The campus utilizes only 15 percent of the acreage with the remaining space devoted to a working farm, cropland, pastureland, and a large natural area. The natural area includes about 44 acres of woodland, 11 acres of wetland and 44 acres of grasslands.

Several smaller unique ecosystems are also present at this site including several springs and a small pond ecosystem. This area provides habitat for several groups of wildlife including nesting areas for waterfowl, quail, pheasants, as well as mammals such as: beaver, muskrat, mink, raccoon, fox and coyote.

Several different plant communities are present. The site contains Douglas fir dominated forests, several wetland plant communities and a large grassland area. These distinct communities result in a high diversity of plants at the RCESC.

The RCESC is considered to be an important natural history area by both the Portland Audubon Society and the Oregon Department of Fish and Wildlife.
