This layer was created for regional staff as a baseline to monitor recovery of shrubs and other vegetation on CDFW mitigation lands in the northern portion of the Carrizo Plain, San Luis Obispo County, California.
The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) has created a layer that depicts the last year of tillage for the CDFW mitigation lands in the northern portion of the Carrizo Plain, San Luis Obispo County, California. This layer was created for regional staff as a baseline to monitor recovery of shrubs and other vegetation. The imagery used was a combination of what was used in the mapping of the mitigation lands: July 2011 1-ft. aerial imagery acquired for San Luis Obispo County and downloaded from USGS EarthExplorer, NAIP 2012, NAIP 2010, NAIP 2009, and San Luis Obispo County 1-ft. imagery from 2007. Ancillary data are the National Agricultural Statistics Service Cropland Data Layers (CDL) for each year from 2007 to 2012 and Aerial Information Systems life form map based on 2007 imagery (AIS 2009). Google Earths historical imagery was also used as ancillary data. Starting in one parcel/block of mitigation land with the 2012 imagery and working backwards in time, tilled areas were delineated until that block was completed. Since the tillage marks from one year could last easily into the next year, the CDL data was sometimes used to confirm tillage. The source of evidence used for the tillage delineation was recorded in the Comments field of the polygon attributes. Rules for minimum mapping unit and minimum width for linear features were followed consequently some linear tillage areas were not delineated.
