NEGATIVE DECLARATION PROJECT: Calaveras Big Trees State Park Vegetation Management Plan LEAD AGENCY: California State Parks AVAILABILITY OF DOCUMENTS: The Initial Study for this Negative Declaration is available for review at: . Central Valley District Headquarters California State Parks 22708 Broadway Street Columbia, CA 95310 . Calaveras Big Trees State Park 1170 State Highway 4 Arnold, CA 95223 . Calaveras County Library-Arnold Branch 1065 Blagen Rd Arnold, CA 95223 . California State Parks Northern Service Center One Capitol Mall, Suite 410 Sacramento, CA 95814 PROJECT DESCRIPTION: This plan addresses the management of vegetative resources at Calaveras Big Trees State Park (CBTSP). A long-term vegetation management plan helps to ensure continuity of actions toward mutually accepted management goals and objectives over time. The Sierra Nevada Conservancy, an agency of the State of California, provided funding for this plan. A copy of the Initial Study is attached.
