The outcome of landscape analysis, especially use of historic and natural range of these discussions could have implications for landscape analysis on variability. An underlying assumption in current USFS approaches is national forests throughout the Sierra Nevada. that managing lands within historical and natural ranges of variability will promote ecological sustainability. Another assumption of interest to SNEP is that social goals can be incorporated into ecological goals to arrive at integrated management objectives. Success in describ- ing historical condition varied considerably by ecological indicator.
