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 represented by a willow dwarf scrubland that has hydrophilic graminoids and forbs throughout. It typically has a defined drainage created by surface flow. The presence of the two communities is temporally dictated by snowpack and snowmelt.
This report provides baseline vegetation inventory data. Future data collection is needed to provide further information about existing plant communities and the disturbance regime that results in transitions from one community to another. Common and scientific names are from the USDA PLANTS database. All community phases are characterized by the Alaska Vegetation Classification System (Viereck et al., 1992).
