Reference State
Description
The reference state supports two community phases that are distinguished by the developed structure and dominance of the vegetation and the ecological function and stability of the community (fig. 5). The reference community phase is scrubland consisting of shrubs, forbs, and graminoids.
This report provides baseline vegetation inventory data. Future data collection is needed to provide more information about existing plant communities and the disturbance regimes that would result in transitions from one community to another. Common and scientific plant names are from the USDA PLANTS database. All community phases are characterized by the Alaska Vegetation Classification System (Viereck et al., 1992).
Submodel
Description
This alternate state is the result of massive landslides. Smaller scale landslides create stable talus slopes, which lead to a partially vegetated early community phase (community 1.2). Massive landslides result in large, non-vegetated talus slopes that remain unstable (figs. 2 and 9). These unstable slopes are susceptible to continuous landslides and are not expected to become vegetated within 100 years. This alternate state is synonymous with ecological site R237XY250AK.
