The central concept guiding the management of parks and Wilderness has been 'naturalness' - to a large extent the explicit purpose in establishing these special areas was to keep them in their 'natural' state. But what does that mean, particularly as the effects of stressors such as habitat fragmentation, altered disturbance regimes, invasive species, and climate change increase? "Beyond Naturalness" brings together leading scientists and policymakers to explore the concept of naturalness, its varied meanings, and the extent to which it provides adequate guidance regarding where, when, and how managers should intervene in ecosystem processes to protect park and wilderness values. The book offers excellent writing and focus on some of the difficult questions being raised in light of new and changing stressors such as global environmental climate change.
