Location Narrative	Big Chico Creek ER, California State University Chico: This is a stand of herbaceous vegetation on a boulder field in a clearing within the surrounding wooded vegetation. The stand contains many species which are characteristic of thin rocky volcanic soils. The soil seems unable to support woody vegetation and non-native grasses. There are some scattered grey pines and Arctostaphylos manzanita in the stand.
