This research provides an estimate of the extent and status of nine species of trees that comprise much of California’s oak forests and woodlands. The authors primarily utilize Landscape Ecology, Modeling, Mapping, and Analysis (LEMMA) Gradient Nearest Neighbor (GNN) georeferenced forest inventory compilations. For this project GNN analyses are used to create maps and tables that show attributes for eight Quercus species (Q. agrifolia, Q. chrysolepis, Q. douglasii, Q. engelmannii, Q.  garryana, Q. kelloggii, Q. lobata, and Q. wislizeni) and tan oak (Notholithocarpus densiflorus). The report’s analyses quantify extent of California’s oak landscapes including mapped distribution of the major California oak species by basal area groupings, an estimate of carbon sequestered in California oak forests and woodlands, and a summary impact of recent fires, and research needs.
