Mixed Woodland

The mixed woodland habitat consists of a combination of Ponderosa pine, madrone, Douglas-fir, and numerous other plant species. This community could further be divided into oak-pine and mixed hardwood-conifer woodland communities. The oak-pine woodland is a zone where oak savannah and chaparral communities merge with a sprinkle of madrone, black oak, Douglas-fir, poison oak, common snowberry, and mountain mahogany. As we move further up the rocks to the base of the andesite cliffs, the well-drained loam soil is rich and moist and encourages diverse vegetation. The dense mixed hardwood-conifer community is dominated by madrone trees, with some California black oak, Ponderosa pine, Douglas-fir, and incense cedar. The dense canopy of this forest community modifies its own environment through shading to cool the temperature and reduce evaporation.
