Location Narrative ? Leininger Ranch is an easement of The Nature Conservancy. This stand consists of dense shrub vegetation dominated by Quercus wislizeni and Umbellularia californica. There is high diversity of shrub species with some emergent Quercus wislizeni and U. californica of tree height. There are fallen, burnt trunks of trees that suggest a fire occurred here within the recent past. The herbaceous layer is sparse.
