Science Spotlight: Rainbow Trout at Redwood Regional
The rainbow trout is a native Californian fish species, originally found on the western coast of North America. They require good quality water to survive and reproduce. so they have become symbols of healthy American watersheds.
Their introduction to freshwater streams worldwide has resulted in their spread from their historical range. Rainbow trout have now spread to all continents in the world except for Antarctica. However, don’t be fooled by the expanded range – the rainbow trout is facing declines due to loss of quality habitats, pollution, and water diversion (to name a few). As a result, multiple species of steelhead (a special form of rainbow trout whose strategy is to migrate to the ocean as juveniles) are federally listed as endangered or threatened.
The rainbow trout’s freshwater stream habitat at Redwood Regional Park is threatened by erosion. The erosion, caused by heavy traffic from hikers, dogs, and bicyclists, causes accumulation of sediments and a decrease in stream water quality. These effects impact multiple species that use the stream for breeding – including rainbow trout and the “Special Concern”-listed California newt.
To do your part in restoring freshwater streams, be sure to stay on the trails and refrain from allowing pets to enter the stream.
Redwood Regional Park shares its legacy with many other Bay Area parks as a redwood forest ravaged by logging. The redwoods that remain today are second and third-generation kin to the giants that once stood at the park.
