BLM Parcels in Butte County, east and southeast of Paradise: A mixed-age grey pine woodland on what may be some type of ultramaphic parent material. The rock appears to be different than the rocks in the surrounding mixed conifer and black oak stands. The tree layer is very open with a dense shrub understory that is mostly dominated by Quercus berberidifolia, but with a whole host of other shrubs. The herbaceous layer contains a significant diversity and cover of native grasses.
