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). This dataset contains the results of the second year of the survey, and enabled the first year of a change analysis (see ds162).

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 ( http://www.nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24570 ).

Supplemental information
Methods are available at: https://nrmsecure.dfg.ca.gov/FileHandler.ashx?DocumentID=42579. The survey methodology is designed to meet the goal of documenting changes in preferred habitat for the Salt Marsh Harvest Mouse, as well as gather the vegetation information in such a way that it can be used for a variety of other purposes. These may include: correlating management activities with vegetation changes; gathering data to support the use of a GIS format that will allow queries and overlaying of additional information such as soil type, ownership, and hydrology; and creation of a base map for future studies. The complete report can be viewed at: http://www.nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24570 . This is the first of five updates since the original map was made in 1999. The second update, done three years later in 2003 (see ds162), is summarized in Suisun Marsh Vegetation Mapping Change Detection 2003 (Vaghti and Keeler-Wolf 2004): https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18254. 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).
