Marin Municipal Water District (MMWD) Aerial Information Systems (AIS) California Native Plant Society (CNPS) 20140307 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/900_999/ds996.zip 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 Relevé protocols). The field-based classification depicts vegetation types that were sampled in 419 CNPS Vegetation Rapid Assessments and Relevés 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. 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. https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16318 and https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=16314 20090101 ground condition Complete As needed -122.796300 -122.559367 38.160835 37.904228 None natural resources vegetation vegetation communities ISO 19115 Topic Categories biota None Marin County California None This dataset is the exclusive property of the Marin Municipal Water District.

Once the question was answered, the veg code was assigned based on the field crew’s findings, and a value of 2 was given to the field attribute in the polygon. A value of 3 was given to polygons that required the reviewer’s guidance, but was not necessarily a field question. Once addressed by the reviewer, then the field value was changed to another pertinent code. There should not be any field attributes with a value of 3 remaining in the final coverage. They were all changed to a different code after being reviewed in the final quality control (QC) check. A value of 4 was given to polygons that were reviewed by MMWD in the Accuracy Assessment.
