program has joined with a monitoring program of the
Environmental Protection Agency, started in 1998, to track and identify sources of pollution in the creek. A year 2000 comprehensive study, in cooperation with the San Francisco State University Masters program reviewed the in-stream chemical, physical and biological qualities of the creek. A key finding of the study was that fecal bacteria levels in the North Fork and Main Stem of San Pedro Creek significantly exceeded the acceptable levels of exposure for recreation per the State of California and the EPA. The recreation use level is pertinent due to beach closures for recreational uses, including surfing, near the creek's mouth on the Pacific Ocean.

Fetid adder's tongue—with its mottled green leaves, brown-purple striped flowers, and odor of rotting flesh—is particularly abundant. The fact that these species normally grow in the shady understory of redwood and Douglas fir forests, has led to speculation that prior to the 5,000 year occupation of the
