Site

The site is about one acre just south of South Seattle Community College and bordered by two trails. It consists of three areas: a flat sunny upper shelf (A), a moderate to steep partially shaded slope (B), and a lower area that is sunny and flat with some wetter sections (C). The current canopy includes cottonwoods and madrones, interestingly growing side-by-side.  Other native species include big leaf maple, beaked hazelnut, dogwood, sword ferns, salmonberry, willow native blackberry, Indian plum, white pine and recently planted Douglas fir. Problematic invasives include: English ivy, Himalayan blackberry, Scotch broom and English holly.
