Santa Rosa is the county seat of Sonoma County, California United States. The 2010 census reported a population of 167,815. Santa Rosa is the largest city in California’s North Coast, Wine Country and the North Bay; the fifth most populated city in the San Francisco Bay Area after San Jose, San Francisco, Oakland, and Fremont; and the 26th most populated city in California. Due to its population, much of Santa Rosa’s remaining undisturbed area is on its urban fringe. However, the principal wildlife corridors of Santa Rosa Creek and its tributaries, flow right through the heart of the town. Great blue herons, great egrets, snowy egrets and black-crowned herons nest in the trees of the median strip on West Ninth Street as well as along Santa Rosa Creek and downtown. Deer often are spotted roaming the neighborhoods nearer the eastern hills, as deep into town as Franklin Avenue and the McDonald area; rafters of wild turkeys are relatively common in some areas, and mountain lions are occasionally observed within the city limits. Raccoons and opossums are a common sight throughout the city, while foxes, and rabbits may be regularly seen in the more rural areas.
In addition, the city borders and then wraps around the northern end of Annadel State Park, which itself extends into the Sonoma Mountains and Sonoma Valley. Annadel State Park also adjoins Spring Lake County Park and Howarth Park, forming one contiguous park system that enables visitors to venture into wild native habitats. Wikipedia
