General Plan Update - City of Inglewood

5.1 Biological Resources
land. Vacant land includes several types of habitats ranging from open water to
woodlands. The exact acreage associated with each of the habitat types within the
watershed is unavailable since many of the open space areas have not been
comprehensively surveyed.
There are five sites within and immediately adjacent to the Dominguez Watershed that
are designated as Significant Ecological Areas (SEA) by the Los Angeles Regional Water
Quality Control Board (Feb, 2000) based on data from the California Department of Fish
and Game, State Water Resources Control Board, and Los Angeles County Department
of Regional Planning. These include Madrona Marsh (SEA 36), Harbor Lake Regional
Park (SEA 35), Rolling Hills Canyons (SEA 31), Terminal Island (SEA 33), and Palos
Verdes Peninsula Coastline (SEA 34). The City of Rolling Hills Estates designated two
areas within the watershed boundaries as Environmentally Sensitive Areas (ESAs):
Rolling Hills Canyons (also a Los Angeles County SEA) and Linden H. Chandler
Preserve.
Special-Status Biological Resources
The following section addresses special-status biological resources observed, reported, or
having the potential to occur within the City of Inglewood. These resources include plant
and wildlife species that have been afforded special status and/or recognition by federal
and state resource agencies, as well as private conservation organizations and special
interest groups such as the California Native Plant Society (CNPS) (List 1A, 1B, and 2).
In general, the principal reason an individual taxon (species, subspecies, or variety) is
given such recognition is the documented or expected decline or limitation of its
population size or geographical extent and/or distribution that results in most cases, from
habitat loss.
Although review of the Natural Diversity Database reveals several records of sensitive
species, most of these are believed to be extirpated or no longer existing within the area
due to the level of development in the City. Field studies would be required to verify the
presence or absence of these sensitive species within the City limits.
Table 5.1-1 in Appendix B lists sensitive plants, animal and habitat types potentially
occurring in and near the City of Inglewood. Special status habitats are vegetation types,
associations, or sub-associations that support concentrations of special status plant or
wildlife species, are of relatively limited distribution, or are of particular value to wildlife.
Special Status Species Descriptions
The South Coast marsh vole, Coastal dunes milk-vetch, Southern tarplant, Coulter’s
goldfield, and Spreading navarretia (federally/state listed threatened or endangered
species) were identified as (moderately) potentially occurring on-site or reported within an
approximately ten-mile radius of the City of Inglewood [see Figure 5.1-1]. Each of the
state and/or federally listed species in Appendix B are described in greater detail.
