Summary

This is part of an ongoing monitoring project that the Biogeographic Data Branch (BDB) of the California Department of Fish and Wildlife (CDFW), in collaboration with the Department of Water Resources (DWR) and the CDFW Bay Delta Region (BDR), started in 1999 to track changes in the Suisun Marsh vegetation over time. This is the fifth update using the current mapping standards since the original map was made in 1999. All of the vegetation maps, including the 2012 map on which this report is based, can be viewed and downloaded using the online CDFW Biogeographic Information and Observation System (BIOS) and the links to the associated reports included in the metadata. The reports can also be downloaded from the CDFW website ( http://www.dfg.ca.gov/biogeodata/vegcamp/veg_classification_reports_maps.asp ).

Description

Supplemental information
To create the 2012 Suisun Marsh re-map, vegetation was interpreted from the true color imagery that was flown at 1:9600 on June 19, 2012 and delivered to VegCAMP in January 2013. Polygons were delineated using heads-up digitizing (i.e., a photo interpreter manually drew polygons around each stand of vegetation) in ArcMAP 10.1 and polygon attributes were recorded within a personal geodatabase. In 2009, staff from the DWRs Mapping & Photogrammetry Section measured the positions of permanent residual features identified both in photographs and on the ground using Garmin 76CSx handheld GPS units. The published accuracy for these units is typically less than 5 meters. A total of 51 control points were measured and used to process the 2009 imagery, which resulted in an ortho-mosaic that closely agreed with NAIP digital orthorectified quarter quadrangle (DOQQ) aerial photography. The same method and control points were used to process the 2012 imagery in order to produce vegetation maps that are spatially comparable. Refer to VegCAMP (2012) for a complete description of the methods used for improving the spatial accuracy of the imagery. There was a large field effort for this mapping cycle that included the collection of 320 reconnaissance points that captured data for 564 vegetation polygons. The 2012 effort also marked the second permanent plot resample since the original plots were sampled in 1999 (the first resample was in 2006). Of the original 198 permanent field plots, 98 were resampled this cycle (VegCAMP 2014). In total, the field data collected in 2012 provided information for over 4.5% (or 3,146 acres) of the total mapping area. All of the data were collected between July and September 2012. Final report associated with this vegetation map to follow.
