Land management in the Anthropocene: Is history still relevant?
Hugh D. Safford, Julio L. Betancourt, Gregory D. Hayward, John A. Wiens, Claudia M. Regan
2008, Conference Paper
Ecological restoration, conservation, and land management are often based on comparisons with reference sites or time periods, which are assumed to represent “natural” or “properly functioning” conditions. Such reference conditions can provide a vision of the conservation or management goal and a means to measure progress toward that vision. Although...
