The vegetation map and survey data help ensure the MMWD is better equipped to manage the vegetation for long-term ecological sustenance. In the future, agencies can compare areas based on vegetation diversity and habitat quality to identify best management regimes for such things as fire hazards, proper trail/road placement, restoration, and other management considerations. This dataset also can be used to assess impacts on vegetation by Sudden Oak Death between 2004 and 2009
The Vegetation Program of the California Native Plant Society (CNPS) has worked collaboratively with the Marin Municipal Water District (MMWD) and Aerial Information Systems (AIS) to produce a fine-scale vegetation classification and map on MMWD lands. Two main project goals were 1) to provide detailed, floristic classification of the vegetation with a report defining the different vegetation types, 2) to provide a detailed vegetation map of the region. Field data are being collected using standard CNPS protocols (e.g., Vegetation Rapid Assessment and Relev protocols). The field-based classification depicts vegetation types that were sampled in 419 CNPS Vegetation Rapid Assessments and Relevs by MMWD staff In 2009 the map completed in 2006 was updated in part to understand how Sudden Oak Death (SOD) had changed the plant communities. The first map was based on aerial imagery flown in 2004 varying from 1/2 ft. to 1 ft. in resolution. The remap used similar imagery flown in 2009. This remap did not include the two outlying area around the Soulajule and Nicasio reservoirs. The attributes in this dataset reflect this, showing two sets of attributes for most of the area.
