FOREST ECOLOGY AND MANAGEMENT | ELSEVIER | Published : 2009
Anthropogenic utilization of forests alters vegetation structure and can negatively affect flora and fauna. Ecological simulation models assist in restoring such degraded forests by predicting the effects of alternative management and restoration actions on vegetation structure. However, the lack of empirical ecological data to parameterize models often necessitates the use of expert opinion. Differences in opinion between experts may be large and lead to uncertainty in model predictions, but this is rarely acknowledged in forest simulation models. In this paper, we constructed state-and-transition simulation models (STSMs) based on expert opinion to predict whether management will expedite ..View full abstract
