In 1994, the Coastal Commission commissioned
development of a database that identifies sources of survey and
monitoring data for 25 Southern California coastal wetlands. The
purpose of the effort was to determine the extent and quality
of existing data that could provide a basis for evaluating the
progress of restoration projects at similar habitats. The database
briefly describes the nature of the data available for each site,
listing: the habitat sampled and parameters, the sample frequency
and duration of the program, sample method, spatial replication,
the type of document in which data are reported and where the
reference can be found. The database does not report the results
of the sampling.

California coastal salt marshes: a community profile. U.S. Fish
and Wildlife Service, Biological Services Program, Washington,
D.C. FWS/OBS-81/54. 110 pp.
Describes the structure and functioning
of California's coastal salt marshes south of Pt. Conception.
Summarizes the physiographic, hydrological, and climatic setting,
the resulting vegetative communities and their roles in overall
marsh functioning. Faunal communities are also described. Discussion
includes analysis of research data from specific sites and forwards
conceptual models of marsh functioning.
MEC. 1993. San Dieguito Lagoon restoration
project regional coastal lagoon resources summary. 56 pp plus
an appendix. Prepared for Southern California Edison.
This report provides a 1-2 page summary
of habitat types, fish, bird and benthic invertebrate populations
at each of 16 coastal wetlands in San Diego and Orange Counties.
It is primarily a synopsis of existing information; sources used
in identifying and quantifying habitat types include aerial photographs
taken in early 1993. The report considers habitat restoration
at San Dieguito Lagoon in light of present and historic conditions
of other coastal wetlands in the region. The sites summarized
are: Tijuana Estuary, Sweetwater River Wetland Complex, Mission
Bay Complex, Los Penasquitos Lagoon, San Dieguito Lagoon, San
Elijo Lagoon, Batiquitos Lagoon, Agua Hedionda Lagoon, Buena Vista
Lagoon, San Luis Rey River, Santa Margarita River Estuary, Las
Flores Marsh, San Mateo Marsh, Upper Newport Bay, Bolsa Chica,
and Anaheim Bay.
Saint, Prem K., Ted L. Hanes, and William
J. Lloyd. 1993. Waterbodies, wetlands and their Beneficial Uses
in the Los Angeles Region (4). Volume 2: wetlands and their Beneficial
Uses. 200 pp.
This report provides brief narrative descriptions
of 78 wetland areas associated with estuaries, lakes and riparian
corridors within Los Angeles and Ventura Counties. All summaries
address basic hydrological conditions and identify vegetative
communities, and contain a map and color photograph; many also
include information on historical conditions, bird and fish species
observed and evaluations regarding the degree of ecological disturbance.
The study was conducted to provide the Los Angeles Regional Water
Quality Control Board with a basis for determining which waterbodies
should have Wetland as a designated Beneficial Use. All sites
were also ranked according to seven functions attributed to wetlands.
Coastal wetlands described are: Ventura River Estuary, Santa Clara
River Estuary, McGrath Lake, Ormond Beach, Mugu Lagoon, Dume Creek
Lagoon, Malibu Lagoon, Topanga Lagoon, Ballona and Del Ray Lagoons,
Ballona Wetlands, and Los Cerritos Wetlands.
MEC Analytical Systems, Inc. 1991. Ecological
descriptions and evaluation of proposed enhancement/restoration
for eight southern California wetlands. Final Report. Prepared
for Southern California Edison. 300 pp. and appendices.
This document describes the characteristics
of eight wetlands in Southern California and provides an assessment
of their relative value as candidates for biological enhancement
and restoration required as compensatory mitigation. The sites
are: Ormond Beach Wetlands, Ballona Creek, Los Cerritos, Anaheim
Bay, Huntington Beach Wetland, Santa Ana River Mouth, San Dieguito
River Valley and Tijuana River Estuary. The assessment is organized
into four parts: historical acreage and present ecological condition;
proposed enhancements and restorations; evaluations of proposed
enhancements and restorations based on biology; and evaluations
of proposed restorations and enhancements based on Coastal Commission objectives and standards. Appendix A describes each wetland site in detail. Data from a variety of existing documents are incorporated into the report.
Wetlands Research Associates, Inc. 1990.
Port of Los Angeles local wetland mitigation program. Approximately
This report, prepared for the Port of Los
Angeles, provides 3-5 page descriptions of 13 sites in coastal
LA County in terms of their physical attributes, habitat quality,
and opportunities and constraints for enhancement. The following
sites are included: Zuma Beach, Malibu Lagoon, Topanga Canyon,
Oxford Flood Control Basin, Venice Canals, Ballona Lagoon, Ballona
Wetlands, Del Rey Lagoon, El Segundo Dunes (<1 acres wetland),
Madrona Marsh, Sanitary District Wetland, Machado Lake, Cabrillo
Tidal Salt Marsh. In addition, slightly expanded (7-8 pp) evaluations
of enhancement opportunities and feasibility are provided for
three sites; Del Ray Lagoon, Machado Lake, and Zuma Beach.
State Coastal Conservancy. 1989. The coastal
wetlands of San Diego County. 64 pp.
This public education booklet describes
ecological concepts and dynamics of San Diego County salt marshes.
The discussion includes watershed processes, littoral and tidal
influences, habitat types, significance to migratory birds, and
the effects of urban development. In addition, summaries of the
history, current values and problems, protection efforts and public
access opportunities are provided for 11 wetland areas. The areas
described are: Tijuana Estuary, San Diego Bay complex, Mission
Bay complex, Los Penasquitos Lagoon, San Dieguito Lagoon, San
Elijo Lagoon, Batiquitos Lagoon, Agua Hedionda Lagoon, Buena Vista
Lagoon, San Luis Rey River and the Santa Margarita River and Estuary.
State Coastal Conservancy. 1982. Regional
wetland restoration study: Los Angeles & Orange Counties.
To facilitate more coherent planning for
restoration and enhancement of coastal wetlands in Los Angeles
and Orange Counties, the California Coastal Conservancy commissioned
an analysis of management needs and opportunities in the region.
The study provides a regional assessment of wetland values, identifies
regional restoration goals, forwards site-specific criteria that
would result in a high likelihood of project success, and describes
10 sites in the region that met the site-specific criteria. Those
sites are: Zuma Beach, Malibu Lagoon, the confluence of the San
Gabriel River and Coyote Creek, Anaheim Bay, Wintersburg Channel,
Huntington Channel Extension, Fairview Park, Talbert Park, Beeco
Oil Field, and San Joaquin Freshwater Marsh. In addition, the
appendices include fish and bird use summaries and habitat acreage
for each site (based on existing information) as well as proposed
improvements to the USFWS wetlands classification system.
