Hello everyone, As you may know LANDFIRE (www.landfire.gov) has developed "reference condition" state and transition models and associated textual descriptions for the ecosystems of the United States. They can be a workable look at what people refer to as Historic Range of Variability (HRV). It is clear with climate change, altered disturbance regimes, invasives, etc. there is a time and a place for HRV as a management goal, but that they are not always useful. What do you think? Are there ecosystem types or situations where reference conditions are more useful than others? Can we provide general guidance for managers who want to use HRV within the context of resilience? I've seen Wiens etal (2012) and other references but would like your opinion. The goal is guidance for managers who are often not able to dig into all of the scientific literature.
Thanks! Randy Swaty
