The California Department of Fish and Wildlife Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation classification and map of the Department's Oak Grove property, San Diego County, California following FGDC and National Vegetation Classification Standards. The vegetation classification was derived from floristic field survey data collected in the field in May 2010 and was based on previously described Alliances and Associations. The map was produced using true-color 2009 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. Supplemental imagery including 2005 1-meter California Color Infrared (CIR) and true-color 1-foot aerial imagery available through GlobeXplorer ImageConnect were also used. The minimum mapping unit (MMU) is one acre, with the exception of wetland types, which were sometimes mapped to ½ acre. Field verification of 45 percent of the mapped polygons was conducted in June 2011; in combination with the 2010 sampling effort, 83 percent of the polygons were verified in the field.
The purpose of the classification and vegetation map is to aid in the development of a management plan for the Oak Grove unit of the San Felipe Wildlife Area. The vegetation classification and mapping provides an inventory of habitat types and a measure of the extent of each type on the property, for use in assessing the biological resources present and determining appropriate management strategies. The mapping also provides a delineation of the location and extent of agricultural fields and old fields present on the property.
Rapid Assessment data were collected from 72 vegetation stands from May 24-28, 2010 following the California Native Plant Society's Rapid Assessment protocol (Appendix A). Additional field reconnaissance data were collected from 51 locations during this same time period. Sample point locations were collected with Trimble Junos (GPS-enabled PDAs) and stored in two ESRI-format shapefiles: "OakGroveDFGSurveys" and "OakGroveReconPoints." Rapid Assessment data were entered into VegCAMP's Rapid Assesment Database (MS Access format).The Rapid Assessment data include the date of sampling, GPS location, environmental characteristics of the sampled stands (microtopography, substrate, soil texture, slope, aspect, ground surface characteristics, disturbance type and intensity), vegetation structure (tree, shrub and herb cover and height, total vegetation cover), species cover, site history, and the Alliance and Association. Additionally, four digital photos taken in the cardinal directions from each Rapid Assessment location are available from VegCAMP. These Rapid Assessment data and field photos can serve as a baseline for monitoring. The Field Reconnaissance data provide observational notes on stand composition and environmental attributes at specific GPS locations in the landscape, and are sometimes associated with photos. The primary use of Field Reconnaissance data was to aid in mapping. Vegetation Classification Methods An initial review of field data found that all major vegetation types (Alliances) observed were described in existing vegetation classifications for nearby locations (Gordon and White 1994, Keeler-Wolf et al. 1998, Keeler-Wolf and Thomas 2000, Evens and San 2006, Klein and Evens 2006, Sawyer et al. 2009). This Alliance list was used to create the vegetation classification and as the basis for mapping. Naming conventions followed the National Vegetation Classification System (Grossman et al. 1998) and the Manual of California Vegetation (Sawyer et al. 2009). An Association is defined by a group of samples that have similar dominant and characteristic species in the overstory and other important or indicator species, whereby these species are distinctive for a particular environmental setting. A set of similar Associations is grouped hierarchically to the next higher level in the classification, the Alliance level. Field Verification Field verification of the draft map was conducted in June 2011 by Rachelle Boul, Diana Hickson, Mary Jo Colletti, Randy Botta, and Melanie Gogol-Prokurat. We field checked 111 polygons. When combined with the 109 polygons for which field data were collected in 2010, a total of 83% of the final Oak Grove polygons were field verified. Additional information, including a Key to Identification of All Stands of Vegetation Sampled or Encountered in the Field and a crosswalk from the Vegetation key to the Map Legend is available at: https://nrmsecure.dfg.ca.gov/FileHandler.ashx?DocumentID=35611 Conventions Used in the Map Attribute Table If a polygon contained a Rapid Assessment data point, the database ID of that sampled stand is noted. The minimum mapping unit (MMU) is one acre for most types, and ½ acre for wetland types. Notes about inclusions of types below minimum mapping unit, etc. are in the notes text field. The property boundaries used for this project are from the Department Lands coverage in 2010. Vegetation polygons were mapped for an unset distance beyond those boundaries. Project Staff Field staff included Randy Botta, Rachelle Boul, Janine Colby, Mary Jo Colletti, John Ekhoff, Melanie Gogol-Prokurat, Diana Hickson, Julie Horenstein, Todd Keeler-Wolf, Kim McKee, Aicha Ougzin, and Rosie Yacoub. Data entry was completed by Mary Jo Colletti; mapping and attribution were completed by Rachelle Boul and Melanie Gogol-Prokurat; the report/metadata was written by Melanie Gogol-Prokurat.
