. Southeast Montana wetland assessment : developing and refining Montana's wetland assessment and monitoring strategy . 50 METERS Figure 8. Releve plot layout (adapted from Peet et al. 1998). After sampling each of the intensive modules, the remaining, or residual, modules were walked to document presence of any species not recorded in the intensive modules. Percent cover of these species was estimated over the entire 1,000 m plot. In the field, vascular plants were identified using the Vascular Plants of Montana (Dorn 1984) as well as ancillary dichotomous keys specific to certain plant gener

Percent cover of these species was estimated over the entire 1,000 m plot. In the field, vascular plants were identified using the Vascular Plants of Montana (Dorn 1984) as well as ancillary dichotomous keys specific to certain plant genera (, carices). The state-based nomenclature was crosswalked to nationally accepted nomenclature based on the USDA PLANTS Database (). Intensive Assessment of Stressors: To capture the actual spatial extent of stressors observed within the 200-m envelope around the AA perimeter, we estimated the percent of the 200-m envelope affected by each stressor. For linear features such as roads, we estimated the length in meters of each stressor within the 200-m envelope. Data Management We created a relational database in Microsoft Access®. All EIA data and vegetation plot data were entered into the database after field data collection was complete. For vegetation data, plant species mean cover values were averaged across modules to get an average cover value for each 15
