The proposed project site is adjacent to the Crescent City Marsh Wildlife Area
(CCMWA), which is owned and managed by the California Department of Fish and
Game (CDFG). The property was acquired in 1979 for protection of coastal freshwater
wetlands. In 1991, the largest known population of the State and federally listed
endangered western lily (Lilium occidentale) was discovered at the CCMWA. The
Department of Fish and Game's primary management goals for this property include
maintenance and enhancement of existing western lily populations, early successional fen
habitats, and coastal prairie vegetation.
The Crescent City Marsh and environs are home to more than 230 plant species, at least a
dozen of which are considered rare, threatened, or endangered by state and federal laws
(CNPS 2001; CDFG 2002). Rare, threatened, or endangered plants of the wetland (fen)
habitats include:
Western lily (Lilium occidentale)
Arctic starflower (Trientalis arctica)
Great burnet (Sanguisorba officinalis)
Green sedge (Carex viridula var. viridula)
Lyngbye's sedge (Carex lyngbyei)
Marsh pea (Lathyrus palustrus)
Marsh violet (Viola palustris)
Vanilla grass (Hierochloe odorata)
Several rare plant communities occur in the Marsh, at least one of which is found
nowhere else in California. Known as buckbean marsh, this plant community is
dominated by the buckbean (Menyanthes trifoliata), more common in the Sierra Nevada
and Cascade Mountains of Oregon.
Significant changes in recharge and storage through subsurface connections between
wetlands of the Crescent City Marsh Wildlife Area and those of the Martin's Ranch
which are proposed for development would likely have significant negative impacts on
the adjacent wetlands and the sensitive species which occupy these habitats. Additional
impacts related to the proposed project include runoff from proposed roads, pesticide-
related impacts from the proposed golf course, and impacts from invasive non-natives
that may be used in landscaping around the development. The proposal does not include
enough information to address these concerns, and the permit should not be issued until
more information and appropriate alternatives are submitted.
IV. Impacts to Listed Species
Direct, indirect, and cumulative impacts to listed species are not adequately
addressed by the project proposal, and cannot be evaluated at this time due to lack
of substantial information.
