|About Sausal Creek :: General Info|
The Watershed is also home to a diverse assemblage of plants and animals. Recent surveys have catalogued over 250 plant species and nearly 80 bird species inhabiting the riparian corridor and uplands. However, this ecosystem has been altered over time and its present condition bears little resemblance to that of the past. Terrestrial and aquatic systems that were once integrated are now dissociated and fragmented by human activities such as logging, urbanization, and fire suppression. Consequences of these human activities include the alteration of the geomorphic processes that shape Sausal Creek; changes in plant communities and the process of plant succession; and an overall loss of biodiversity.
Not only has the Watershed's urbanization resulted in habitat loss, but the Watershed's native diversity has been replaced, in many areas, by exotic species--Algerian and Cape ivy displace native gooseberry and wild rose in the riparian corridor; Eucalyptus and Monterey pine now grow where productive grasslands once clothed the hillsides; European starlings and rock doves occupy habitat once belonging to meadowlarks and burrowing owls. Nonetheless, native black phoebes and Wilson's warblers still make use of Sausal Creek; dogwood and scarlet monkey flower can occasionally be found growing along its banks; backswimmers still live in its pools; and damselflies hover above its waters.
