Wildflowers in a Native Oak Woodland and Open Grassland on Bell Springs Mountain

The Oak Forest

The deciduous oak forests on Bell Springs Mountain consist of Oregon white (Quercus garryana), and California black (Quercus kelloggii) species. The forest goes through dramatic seasonal changes. Dormant and leafless about 6 months of the year revealing a vast living community of mosses, leafy lichens and mistletoe on the trunk and branches. Colorful yellow, orange and red leaves emerge in the spring while the adjoining grasslands produce a wide spectrum of intense green color. The summer woodland has a dark green canopy partially shading the annual wildflower show playing on the forest floor below. In the fall the leaves turn yellow and brown as the trees shuts down for the winter.
