Digital point locations were verified over digital USGS topographic maps (DRGs). Logical_Consistency_Report: ESRI point geometry. All point features are unique. There are no duplicate points. Completeness_Report: Each plot is represented by one point. All points fall within the mapped polygons. Lineage: Process_Step: Process_Description: Detailed, quantitative data from the least disturbed areas of the Park were collected in order to augment data available for a regional vegetation classification. Quantitative plot data was collected only in the highest quality stands of floristically and structurally homogeneous vegetation. These were middle to late successional stands with a composition of mostly native species and with a consistent environmental setting. An attempt was made to find at least one undisturbed sampling location for each mid-to-late successional community type in the Park. Specific plot locations were chosen subjectively in order to distribute plots across a range of site conditions and to capture stands that were relatively dominant, homogenous, and covered a minimum mapping unit area of half a hectare. Early-successional forests and heavily disturbed areas within the park were not sampled using quantitative methods. Eleven quantitative vegetation plots were sampled from May through September 2002-2006.
