Explanation of the Profile Categories

GENERAL

Source #
Site Name of the site
Numbers refer to the annotated citations in the source section.
Map Refers to the accompanying habitat and historic extent maps. USGS 7.5' quadrangle nomenclature is used.

Location General site locator

Contacts Contacts who have an active interest in the site and are likely to be aware of any additional or updated information.

Approximate Wetland Habitat Acreage Several points should be made about the acreage figures: 1) They are provided as an approximate indication of the areal coverage of the resource. 2) They are derived from the literature and are presented here out of context; depending on


the source, the figures may or may not be derived from a delineation of jurisdictional boundaries. Source documents are identified and should be referred to for definitions used, date and method of surveys. 3) Their appearance in this database alone does


not infer concurrence of regulatory agencies. 4) Habitat types making up the total area are identified later in the profiles; totals may include large areas of open water and "transitional" habitats.


5) Finally, since wetland acreages were not derived from the maps, the degree of correspondence with the accompanying habitat maps is uncertain.

Approximate Historic Acreage Acreage figures are provided here to give an approximation of the historic extent of the wetland area. They are derived from the literature which in each case is at least a secondary source. Since they are drawn from different sources, the degree of correspondence with what is shown on the accompanying historic maps is uncertain.





Ownership Owner Acres Source

Ownership and acreage information are intended to refer to the wetland area, however depending on the emphasis of the source materials, they may include upland areas. The area owned by a particular entity may extend beyond the wetland, so in some cases the total ownership acreage will not be the same as the approximate wetland habitat acreage.





LAND USE

Source
Land Use Designation May include general plan, local coastal plan, special area or zoning designations.

Onsite Use Describes current uses being made of the area, including those that cross the wetland such as levees or roadway berms. In some cases, as with San Diego and Mission Bays, the information may refer both to the wetland site and to a larger, surrounding waterbody.

Historic Use The focus of this category is uses that occurred in the past but have since stopped. Ongoing uses that have been in place for a long time may also be listed here to indicate a long and continuing influence.

Adjacent Use This describes the uses of the area immediately surrounding the wetlands. In some cases this includes areas that were once part of the wetland but which have been converted to uplands.

Historic Adjacent Use This describes uses of the immediately surrounding lands that occured in the past but which have since been abandoned. It may also include current uses that have been in place for many years.





HYDROLOGY

Source
Tidal Influence This category is meant to give an indication of the extent of tidal influence the wetlands receive. The objective is to address on a basic level whether the tidal reach is constrained, and if so, to what degree and in what way.

Wetland Watershed Area The area that catches precipitation which ultimately drains into the wetland.





Tributaries and Flow Tributary Flow Source

Identifies tributaries that empty into the wetland. This category is meant to give an indication of the tributary's relative influence on the wetland. It will usually contain peak flow rates and other information describing the character of the tributary such as whether it is channelized, and whether flows are seasonal.
Dams Entries will identify: the dams in the watershed, the area that flows into the dam and the date of construction where available.

Other Sources Other sources of fresh water inflow such as groundwater or storm drains.





WATER QUALITY

Source
General Notable conditions not covered by the three parameters listed below such as the presence of pollutants. Also identifies Regional or State Water Quality Control Board water body assessments and designated Beneficial Use Categories.


Refer to the Terms and Definitions section for explanations of Beneficial Uses and Waterbody Assessments.

Dissolved Oxygen (DO) Dissolved oxygen concentrations are tied to a number of factors and may vary within a site under normal conditions. The range for the site over a specified period will be reported. Where possible, information about the sampling regime will also be reported including frequency, area of the site covered, and the time of day and depth of samples. Also if specified, information will be provided regarding when and where low concentrations were recorded.

Water Salinity Salinity concentrations may vary within a site under normal conditions. Where possible, the range for the site over a specified period and the depth of the sample will be reported.

Sediment General description of the dynamics of sediment input into the wetland, when available this will include sedimentation rates.





Soil

Source
Soil Characterizations of soils at the site. Information in this category will be reported in the most specific terms found.





Habitat Acres Vegetation
The habitat lists are organized generally from lowest elevation to highest. Habitat descriptions and vegetative community groupings are those used in the source documents. Information on upland habitats is included to give an indication of the extent of upland buffer. Total wetland acreages do not include eelgrass or upland areas, and depending on how the habitat is described in the source document, transition areas may be included. Acreages are taken directly from the source documents. These should be referred to for date, method of survey and definition used. This category lists the dominant species if ranked, and special interest species identified during the most recent survey(s) available. The year of data collection precedes the list. If the date of sampling was not specified, then the year of the report is provided. The presence of cordgrass, an increasingly scarce native component of the low salt marsh and habitat for the endangered light footed clapper rail, is noted. Exotics are indicated by an asterisk, special interest species by a plus.




ANIMAL USE

Source

The aim for all the animal categories is to provide an indication of the diversity of wildlife using the site on the date of survey, including species of special concern and introduced species. Also if possible to provide an indication of the distribution of introduced species relative to natives. The year of data collection precedes the list. If the date of sampling was not specified, then the year of the report is provided. The focus for the profile is animals identified in wetland areas, but specific habitat information was not always identified in the source material. Animal sightings may have included upland habitats.

Birds The typical bird entry will contain the total number of species identified over a particular period and the number of those that are water-associated, defined as pelicans, grebes, cormorants, herons, egrets, waterfowl (ducks, swans and geese) small and large waders, (shorebirds) gulls, and terns. It will also have the number of sensitive species and when identified, names of sensitive species nesting at the site. The year of data collection precedes the list. If the date of sampling was not specified, then the year of the report is provided. (Also see explanation under Animal Use).

Fish These entries will usually contain the total number of species collected over a specified sampling period, and the most abundant species when quantified, or those otherwise highlighted in the report text. When identified lists will also include significant native and introduced species. Information about the sampling regime, including frequency, area of the site covered, and gear used will also be provided where possible. (Also see explanation under Animal Use).

Benthic Invertebrates A typical entry will list for the given year or period: the total number of species found, dominants if quantified or species otherwise highlighted in source documents, and significant native and introduced species. Where possible, information about the sampling regime will also be reported including frequency, habitats sampled, and gear used. (Also see explanation under Animal Use).

Insect To the extent possible, the insect entries will take a similar form to those of the other animal categories, listing total number of species or orders, dominants, and species of note found over a particular period. However, insect data for wetlands is typically limited. Where surveys have been done they often focus on particular species such as pests or special concern species.

Other Wildlife This category includes information on mammals, reptiles and amphibians as available. Generally the number of species identified from each group is listed, with special status and predator species named. Where possible, the entry will specify whether the animal was sighted in a wetland area or on uplands and make the distinction between sighting of the actual animal and evidence of the animal (i.e. scat).

Special Status Species This category lists all plant and animal species found onsite on the indicated date(s) that have any of the following designations: Federal - Endangered, Threatened, Candidate, Species of Concern (C1), Species of Concern (C2), Proposed, and Federal Sensitive Species. State - Endangered, Threatened, Rare, Candidate, Species of Special Concern. The emphasis is on wetland or water-associated species but depending on the number of species and space in the profile, upland species may also be listed.





OUTLOOK

Source
Enhancement Status Identifies and briefly describes any plans, implemented projects, or other efforts aimed at improving wetland health, including projects carried out as mitigation for impacts onsite or elsewhere.

Watershed Management Identifies and briefly describes plans or actions either under development or being implemented in the wetland watershed that will benefit the wetland. Efforts may be oriented towards managing or protecting the entire watershed or focused specifically on the downstream wetlands.

Pressure Identifies activities, land use issues or other resource conditions which limit a wetland's capacity to restore itself.
