| Observation Narrative |
original plot ID: AA0808, Vegetation type confidence: Difficult polygon to assess but appears to be a Quercus agrifolia - Juglans californica with numerous tall and short shrubs species - very diverse.; not high confidence for separation of non-native and native herb species cover.(new growth). Other short shrubs 2% of cover. Pinus sp in northern tip of polygon. Herbaceous throughout. Diverse polygon - significant understory shrubs. Quercus agrifolia and Juglans californica appear in most areas of polygon. If foliated, Juglans californica cover would be higher.;
