Description
These areas were historically kept free of extensive brush and tree cover by burning. Typical native plant species found on the site include Roemer’s fescue (Festuca roemeri), camas (Camassia quamash), prairie junegrass (Koeleria macrantha), California oatgrass (Danthonia californica), field chickweed (Cerastium arvense ssp strictum) and Oregon white oak (Quercus garryana). In some areas, these sites are influenced by various abiotic factors such as prevailing winds (especially across marine waters), proximity to unprotected marine waters, or elevation, which will cause these locales to be cooler than the climate generally associated with these soil series. This is referred to as the Cold Phase in the ecological site description. The effect on the plant community is generally the absence of Oregon White Oak from the community.

Mechanism
This transition occurs when uncontrolled disturbance is persistent in the system, such as: overgrazing; mowing in the wrong season, wrong height, or at the wrong frequency; vehicle use that causes vegetation damage; or too-frequent fire. In addition, non-native plant seeds or propagules or present on or near the site.
Mechanism
No fire or other disturbance – This transition occurs when disturbances, either natural or man-made, are reduced or eliminated through actions such as fire control, or cessation of activities such as mowing, soil perturbation grazing or vehicle access.
Mechanism
Restoration – removal of non-native species and restoration or the original plant community through methods such as prescribed fire, brush control, invasive plant control, mowing, thatching, grazing, and/or soil aeration and reseeding.
Mechanism
No fire or other disturbance – This transition occurs when disturbances, either natural or man-made, are reduced or eliminated through actions such as fire control, or cessation of activities such as mowing, soil perturbation grazing or vehicle access.
Mechanism
Tree Removal and Restoration – Harvest and removal of trees from the site; or girdling of trees. Additionally, removal of non-native species grass, forb and shrub species and restoration or the original plant community through methods such as prescribed fire, brush control, invasive plant control, mowing, thatching, grazing, and/or soil aeration and reseeding.
