Two common questions asked of resource managers include, “are ecosystems resilient to existing and planned disturbance patterns” and “are you keeping the common species common”? These can be very difficult questions to answer, and even defining the terminology in those questions can be an onerous and sensitive process. Ecosystems are not static. Plant and animal composition, productivity and nutrient cycling, all change in response to stochastic events and successional change (Gunderson 2000). Sustainable ecosystems, however, maintain these traits within stable bounds. Plant succession following tree fall creates a heterogeneous mosaic of vegetation in forest ecosystems (Denslow et al. 1990) but maintains a characteristic vegetation pattern at the landscape scale. Similarly, in many ecosystems predictable successional changes in ecosystem parameters follow natural wildfires (Stark and Steele 1977, Van Cleve et al. 1991, D’Antonio and Vitousek 1992). However, the landscape as a whole does not change because fires in some patches are balanced by successional development in other patches (Watt 1947, Turner 1989). Biological diversity appears to play a substantial role in ecosystem resilience and in sustaining desirable ecosystem states in the face of change (Peterson et al. 1998). Elmqvist et al. (2003) suggested that the diversity of responses to environmental change among species contributing to the same ecosystem function, which they called response diversity, was critical to change. Dealing with the concept of ecosystem resilience requires stratifying a landbase into distinct but workable ecological units, identifying species or group of species that are associated with such units, and integrating ecological units and characteristic biodiversity into an effectiveness monitoring plan that will allow foresters to cope with uncertainty and surprise in landscapes that have been logged.
