Originating at elevations over 9,000 feet, Meeks Creek courses 7.5 miles through high mountain lakes, steep rocky terrain, and montane meadows in a broad U-shaped valley before passing beneath Highway 89 and emptying into the Meeks Bay Marina and Bay on Lake Tahoe at 6,625 feet elevation. Within the broad valley upstream of Highway 89 lies a 500-acre “meadow” (herein Meeks Meadow or Site) comprised of mixed conifer forest interspersed with graminoid meadows, riparian scrub and diverse wetland features. The ecological conditions in Meeks Meadow have been altered as a result of Comstock era1 disturbances (i.e., logging and grazing), cessation of the natural and indigenous fire regimes, and climate change. What was once a complex mosaic of riparian, meadow and late successional forest environments has been converted to broad expanses of early seral forest communities dominated by lodgepole pine (Pinus contorta ssp. murrayana). The actions described in this Restoration & Management Plan (RMP) intend to hasten successional processes in an effort to restore late-seral meadow, riparian and forest habitats in the context of the current and future climate regime. 1.2 MANAGEMENT CONTEXT The environmental conditions in Meeks Creek watershed are detailed in the Ecological Assessment Report (EAR) prepared by the United States Department of Agriculture - Forest Service (USFS) Lake Tahoe Basin Management Unit (LTBMU) (LTBMU, 2006a). Based upon the conclusions of the scientific studies presented in the EAR, the following restoration actions were recommended to restore ecosystem function in the
