Summary

The Suisun Marsh is one of the largest contiguous brackish marshes remaining in the United States. In 1977 the Suisun Marsh Preservation Act was legislated and required that the Suisun Marsh be managed for its wildlife resources. As part of the monitoring program in the Plan of Protection, a Triennial Vegetation Survey was developed to document the overall vegetation composition of the marsh and to monitor Salt Marsh Harvest Marsh (SMHM) habitat by the use of aerial photography in combination with ground verification. However, there were some concerns about the methodology used and the lack of useful maps from the 1988, 1991, and 1994 surveys. In 1996, an interagency technical committee was convened to review the current survey methodology and recommended a more detailed monitoring system for vegetation changes within the marsh. Consequently, in July 1997 the committee agreed to implement a new survey methodology for the 1998 vegetation survey. The first survey was complete in 1999 (see ds160). The dataset containing the results of the second year of the survey are reported in ds161. This enabled the first year of a change analysis by comparing vegetation in June 2003 and June 1999 (reported herein).

Description

This vegetation mapping project of Suisun Marsh blends ground-based classification, aerial photo interpretation, and GIS editing and processing. The method is based on the development of a quantitative vegetation classification, which is used to describe the vegetation map units of the marsh. The classification is defined to meet the specifications of the National and State standards for vegetation classification, but is related through a cross-walking table to other standard classifications in use locally or statewide.

Supplemental information
250 releve field samples were collected in 1999. 250 rapid assessment field samples were collected in 2000. 99 rapid assessment field samples were collected in 2003. The complete report is available at: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18254 . The attributes described in the 2003 Suisun Marsh Vegetation Change Detection report differ slightly to what is actually presented in this dataset. All attributes that reference the 1999 vegetation map (see Table 2 in the report) have been removed from this dataset, which now only reflects data for the 2003 Suisun Marsh vegetation. This is the second of five updates since the original map was made in 1999. The first update was conducted one year after the initial aerial photo-interpretation (see ds161), is described in Vegetation Mapping of Suisun Marsh, Solano County (Keeler-Wolf and Vaghti, 2000): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24570. The third update, done in 2006 (see ds500), is summarized in 2006 Vegetation Map Update for Suisun Marsh, Solano County, California (Boul and Keeler-Wolf 2008): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=48107. The fourth update, done in 2009 (see ds711), is summarized in 2009 Vegetation Map Update for Suisun Marsh, Solano County, California (Boul and Keeler-Wolf 2012): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=48108. The fifth update was done in 2012 (the vegetation map and report are not yet available to the public).
