Annadel State Park is a state park of California in the United States. It is situated at the northern edge of Sonoma Valley and is adjacent to Spring Lake Regional Park in Santa Rosa. It offers many recreational activities within its property. The rock formations of Annadel have played central role in its history: its volcanic origins, the Native American use of obsidian, the early 1900s mining of cobblestones, and modern hikers' appreciation of its volcanic rock outcrops. These lands were occupied by the Wappo and Pomo people in prehistoric times, who would have primarily inhabited the riparian zones and the marsh perimeter. Annadel includes what some biologists consider the best example of undisturbed northern oak woodlands in existence.〔(Annadel State Park facts )〕 Visitors can enjoy the park's diverse wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom. ==Ecology== Plant communities include California oak woodland, riparian woodland, Douglas fir forest, chaparral, grassland, and marsh. The dominant plant community is the oak woodland, which has a canopy of coast live oak, Garry oak, black oak, Pacific madrone, bigleaf maple, and California laurel. Canyon live oak occurs in swales and creeks. In the oak woodlands, the dominant understory plants are native bunchgrasses, toyon, wild blackberry, coyote brush, and western poison-oak. The latter covers nearly one quarter of the understory in the park.〔Hogan, C. M. (2008). (Western poison-oak: ''Toxicodendron diversilobum''. ) In: Strömberg, N. (ed.) GlobalTwitcher.〕 Douglas fir occurs in some of the steeper, cooler riparian zones and on north-facing slopes. Common animals in Annadel include black-tailed deer, western gray squirrel, raccoon, skunk, and opossum. Bobcat and mountain lion are occasionally observed. There are many bird species, including the western scrub jay, Steller's jay, acorn woodpecker, black phoebe, and dark-eyed junco. In moist areas, amphibians such as the rough-skinned newt can be found. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Annadel State Park」の詳細全文を読む スポンサード リンク
