Riparian Projects


MONO BASIN

In the eastern Sierra Nevada, PRBO is monitoring bird populations to assess three major riparian stream restoration projects in the Mono Basin and the Owens River Valley. Each of these projects relies on a passive restoration technique -the return of water (and hydrologic function) to systems that have been partially or entirely diverted for decades. PRBO's results demonstrate how effective this technique can be, as exemplified in our oldest such project, Mono Basin Stream Restoration.

Water that had been diverted to the Los Angeles Aqueduct since 1941 began returning to Mono Lake's feeder streams following record snowmelt in 1982-83 and a major state policy change in 1989 (Observer 99, Spring 1994).

PRBO has been assessing songbird population recovery on two of these streams, Rush and Lee Vining creeks, since 1998. We have:

CLEAR CREEK

Since 1999, PRBO has been monitoring bird populations in the Lower Clear Creek Floodway Rehabilitation Project, near Redding, California. The project's initial focus was to improve passage and spawning habitat for salmonids, but Clear Creek has some of the best remaining riparian songbird habitat in the Sacramento Valley. PRBO's work, largely funded by CalFed, allows the restoration team to take a multi-species, ecosystem-based, adaptive management approach. Bird data has been incorporated into restoration design in order to maintain and create high-quality riparian bird habitat that benefits birds such as Yellow-breasted Chat, Yellow Warbler, and Song Sparrow.
