The California red-legged frog occurs from sea level to elevations of about 1,500 meters (4,921 feet), primarily in wetlands and streams in coastal drainages of central California (GGNRA 2009). This frog requires a variety of habitat elements with aquatic breeding areas embedded within a matrix of riparian and upland dispersal habitats. Breeding sites are in aquatic habitats including pools and backwaters within streams and creeks, ponds, marshes, springs, sag ponds, dune ponds, and lagoons. The adults require dense, shrubby, or emergent riparian vegetation closely associated with deep (greater than 2 1/3-feet deep) still or slow moving water. The largest densities of California redlegged frogs are associated with deep-water pools with dense stands of overhanging willows (Salix spp.) and an intermixed fringe of cattails (Typha latifolia) (GGNRA 2009). California red-legged frogs aestivate (enter a dormant state during summer or dry weather) in small mammal burrows and moist leaf litter. They have been found up to 100 feet from water in adjacent dense riparian vegetation. Recent studies have confirmed that Rodeo Lake/Rodeo Lagoon complex is used as a breeding site for red-legged frogs (Fong et al. 2010). Red-legged frogs and other amphibians have been found as road-kill along Bunker Road. Bunker Road bisects Rodeo Lake and Lagoon. Rodeo Valley stables occur on Bunker Road, approximately 0.5 mile east of this location. Red-legged frogs currently occur in extremely small numbers in the Redwood Creek watershed (Fong et al. 2010). Lower Redwood Creek Pond was constructed in 2007 in this watershed to provide redlegged frog habitat. It is located in a floodplain between the Golden Gate Dairy and Lower Redwood Creek sites. In 2010, the NPS introduced red-legged frog egg masses into the Lower Redwood Creek pond. Subsequent to the action, juvenile frogs have dispersed into adjacent Redwood Creek. Small populations of California red-legged frogs occur in the Tennessee Valley drainage. In 2004 three red-legged frogs were found on stream surveys along the main stem of Tennessee Valley Creek, adjacent to the Lower Tennessee Valley site (Wood 2004).

The northern spotted owl (Strix occidentalis caurina) is a federally listed threatened species. Marin County supports a northern spotted owl population of possibly 75 pairs, the highest known density of northern spotted owls rangewide (GGNRA 2005). Spotted owls in Marin inhabit coniferous forest, including second growth and remnant stands of Douglas fir, bishop pine, coast redwood, and mixed evergreen-hardwood habitats comprised of tanbark oak, coast live oak, and California bay (Fehring et al. 2002 as cited in GGNRA 2005). Spotted owls are known from Kent Canyon and Camino del Canon (nesting) as well as in Muir Woods, within two miles of Golden Gate Dairy (B. Merkle pers. comm. 2010). Threats to spotted owls in the planning area include urbanization, intense recreational pressure, disturbance from wildlife photographers and birders, genetic isolation, West Nile virus, possible catastrophic wildfire, expansion in the range of the barred owl (Strix varia), and habitat changes due to Sudden Oak Death (Fehring et al. 2002).
