Field data for the Vegetation Mapping Inventory Project of Grand Portage National Monument
2007-2009. Field data for the Vegetation Mapping Inventory Project of Grand Portage National Monument
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. During the summer of 2007, botanists collected vegetation samples for plant community characterization. We entered the sampling data into the National Park Service (NPS) PLOTS Database (NatureServe 2005) and performed analyses, which provided detailed ecological information to affirm plant communities at the GRPO and document them with local descriptors. The vegetation classification was later modified with additional field reconnaissance and data from AA sites. Before mapping, we performed field reconnaissance during the summer of 2008 to correlate vegetation types to their appearances on aerial photographs. This resulted in the development of a map classification. An understanding of vegetation types is essential for mapping them. As vegetation concepts became known from either field or lab, we applied them to our photointerpretative mapping.
