1. Upland Forest
The area that is an upland forest has a closed canopy forest dominated by Pseudotsuga menziesii (Douglas fir), the most common conifer and Acer macrophyllum (big leaf maple) the most common deciduous tree. The area has been logged, the current tree cover being second growth.
2. Wet Meadow
The wet meadow at RCESC is dominated by grasses and inter-mixed rushes and sedges. The area is adjacent to bottomland forest and emergent wetlands.
3. Bottomland Forest
This forest is dominated by red alder, Oregon ash, and Scouler's willow as well as several species of shrubs (e.g. cascara, Douglas hawthorn, Pacific ninebark). The area has saturated soil for much of the spring and into the summer.
4. Emergent Wetland
The emergent marsh is fourteen acres and receives water from Rock Creek during high flows and from adjacent springs. The vegetation is dominated by reed canary grass, bentgrass and tall fescue as well as several species of rushes and sedges.
5. Riparian
A channel associated with Rock Creek flows on the northwest side of the property. The banks of the channel are wet meadow and the soil is hydric. The stream is utilized by various waterfowl, and several species of fish.
6. Open Field
The grasslands within RCESC are a mix of upland and wet meadow. They are important habitats for small mammals and for grazing ungulates (e.g. black tailed deer).
