[7] There are over fifty geographic place names in California with the word "wildcat", which either refers to the historic presence of bobcats (Lynx rufus) or to its meaning as an "unsound scheme".

In April, 2010, the plan was published and addressed three goals: In September 2010 the City of San Pablo announced that it had received a $1.8 million grant from the state Department of Water Resources to clean up Wildcat Creek.

[10] Wildcat Creek supported a steelhead run historically, but degradation of habitat and construction of passage barriers from urbanization likely resulted in their extirpation sometime after 1915.

[2] Recently the East Bay has seen a renaissance of the native coastal rainbow trout in the watershed, and some have been spotted in the creek in Downtown Richmond nesting in submerged shopping carts and other garbage.

[2] The recovering 387-acre (157 ha) Wildcat Marsh (once stretching to San Pablo Creek as part of a dynamic, contiguous 2,000-acre (810 ha) system) supports a diversity of endangered and threatened species, including the California clapper rail (Rallus longirostris obsoletus), the black rail (Laterallus jamaicensis), the salt marsh harvest mouse (Reithrodontomys raviventris), and the San Pablo vole (Microtus californicus sanpabloensis).

[6] In April 1991, a student at the University California, Berkeley electrofished the two perennial reaches of Wildcat Creek to determine the condition of O. mykiss populations.

The resulting study reported that the presence of multiple age classes in both the upper and lower reaches indicated successful spawning in the two areas (Cohen 1991).
