      The perception that large-scale change to Suisun Marsh is inevitable was the stimulus for a symposium on Suisun Marsh in the 21 st Century: a landscape of change and opportunity. This symposium, in turn, was a kick-off for producing a book on the history and future of the Marsh. These results suggest that salt marsh harvest mice have a more flexible diet than previously thought, and will allow land managers in areas such as the Suisun Marsh to promote the growth of plants.

For all these reasons and more, Suisun Marsh is a very loved and distinctive place that many people and agencies are striving to protect. The California Department of Fish and Wildlife, Vegetation Classification and Mapping Program (VegCAMP) is just one group that has invested considerable energy in supporting the conservation of Suisun Marsh.

survey can be used for a pre-gate operation base line. The Triennial Vegetation Survey was carried out in the Suisun Marsh in,and to document any changes in vegetation composition over time.

There were some concerns about the methodology used and the lack of useful maps from the, and surveys. The Suisun Marsh is the largest contiguous brackish water wetland in western North America, providing food and habitat for thousands of migratory birds and many species of plants, fish and wildlife.

The combination of tidal wetlands, diked seasonal wetlands, sloughs and upland grassland comprises more than 10 percent of the remaining wetlands. The Suisun Marsh Vegetation map was created by the California Department of Fish and Game, Wildlife and Habitat Data Analysis Branch.

This coverage represents the distribution of vegetation for Suisun Marsh based on interpretation of aerial photographs flown on J and further updated with photographs flown July 5, CDFW BIOS GIS Dataset, Contact: Todd Keeler-Wolf, 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. to track changes in the Suisun Marsh vegetation over time and to fulfill specific permit requirements, the Suisun Marsh Plan of Protection (), and the 1981 Suisun Marsh vegetation survey book Marsh Preservation Agreement ().

This is the fifth update using the current mapping standards that were originally implemented The Triennial Vegetation Survey was conducted in Suisun Marsh in,and to document any changes in vegetation composition over time. There were concerns about the methodology used and the lack of useful maps from the, and surveys.

The Triennial Vegetation Survey was conducted in Suisun Marsh in,and to document any changes. Because the Suisun Marsh is a unique and valuable natural resource in which all the people of the State have a substantial and continuing interest, and because the wise use, conservation and enhancement of marsh and managed wetland habitats for the benefit of present and future generations are of great concern to the people of California, it.

“Fresh-brackish marsh” vegetation is indicated by presence of cattails (Typha) in the low marsh zone in addition to tules and bulrushes, and presence of unspecialized or salt-intolerant freshwater marsh plants with significant frequency in the vegetation.

Northern pintail Anas acuta (hereafter pintail) populations wintering within Suisun Marsh, a large estuarine managed wetland near San Francisco Bay, California, USA, have declined markedly over the last four decades.

The reasons for this decline are unclear. Information on how hunting and other factors influence the selection of vegetation types and sanctuaries would be beneficial to manage.

Two species of Reithrodontomys raviventris are recognized. The subspecies of study, R. raviventris halicoetes, the Northern Salt Marsh Harvest Mouse, is found in the marshes of northern and central San Francisco Bay, particularly in the marshes of San.
