Cow Creek Ranch is a Shasta Land Trust easement property. Mixed grey pine and blue oak woodland on the steep upper north facing slopes of Parker Ridge. There are a number of very large Pinus sabiniana in the stand as well as many saplings. Quercus wislizeni and oracle oak are scattered throughout the stand as well. The shrub layer is mostly open with poison oak and Arctostaphylos manzanita as the primary shrub species. The herb layer has a fair amount of native grasses in it.
