An ecological assessment of natural resource conditions in and adjacent to Redwood National and State Parks, Whiskeytown National Recreation Area, and Oregon Caves National Monument was conducted with the following objectives: 1) provide an initial, science-based evaluation of resource condition status of the Parks and include the associated data used for the evaluation; 2) provide a report that allows Park superintendents and managers to meet Government Performance Results Act and Office of Management and Budget reporting requirements; and 3) develop a reproducible framework for the assessment that can be used at other park units.
