reptile classification follows Stebbins (1985) and Jennings (1987), while mammal nomenclature and        
phylogeny is based on Jones et al (1982, 1986).    
(b) Sensitivity Status codes are for animals considered sensitive by local, state, and federal governments    
(CDFG 1994, 1997, 1998; USFWS 1996):    
CFA = species protected by the California Department of Fish and Game (CDFG)    
CSA =species considered sensitive by CDFG    
FT= species listed as threatened by the federal government    
FCC= Federal Species of Conservation Concern (Dec. 2002)    
MHCP = target species of the North Coastal Multiple Habitats Conservation Plan    
MSCP = target species of the North County Multiple Species Conservation Plan    
SSC = CDFG Species of SpecialConcern    
( c ) Vicinity refers to the privately owned Preston parcel within 1,500 feet of the Preserve    
(d) Residency codes:    
SR = Spring/summer (breeding) resident    
V = Visitor occurring irregularly or a regularly occurring migrant in spring and/or fall    
WR = Winter (non-breeding) resident    
YR = Year-round resident    
(e) Species that were not detected within the Preserve but were observed on adjacent roads.
