Interpretive Summary: State-and-transition model development is described, including the use of literature review, participatory data collection, and interviews to develop models. Local knowledge is also critical to describing the causes of transitions among states. Historical ecological states and processes that may be considered as references for ecological assessment are discovered via historical profiling/assessment techniques. The characteristics of extant ecological states are identified through ecological field data collection on vegetation, soils, and sometimes animal communities. Statistical analysis, including multivariate and machine learning techniques, are used to develop and validate concepts for ecological states. Management experiments are used to test the processes involved in transitions. Spatial mapping, via automated image classification or manual polygon delineations using remotely sensed imagery, is used to map ecological states for use in management. Technical Abstract: State-and-transition model development, as described in this chapter, relies on a suite of other methods to develop models. Science and local knowledge is synthesized and initial models developed via literature review, participatory data collection, and interviews. Local knowledge is also critical to describing the causes of transitions among states. Historical ecological states and processes that may be considered as references for ecological assessment are discovered via historical profiling/assessment techniques. The characteristics of extant ecological states are identified through ecological field data collection on vegetation, soils, and sometimes animal communities. Statistical analysis, including multivariate and machine learning techniques, are used to develop and validate concepts for ecological states. Management experiments are used to test the processes involved in transitions and for structural or functional thresholds (sensu Lopez et al. 2011, Sasaki et al. 2018). Spatial mapping, via automated image classification or manual polygon delineations using remotely sensed imagery, is used to map ecological states for use in management. |
