Vegetation associations were identified based on the field key and plant identification. If additional communities were found within a 50 meter radius of the plot center, they were recorded as well. During the analysis, it was concluded that some attributes were in error and changed to match the mapped attributes. This was done by examination of the aerial photographs under stereoscopic view. The attributes were in error due to 1) spatial error in the GPS derived coordinates (4-8 meters), 2) change of vegetation community due to temporal changes, or differences between observation team identifications. Logical_Consistency_Report: All attributes are codes that correspond to vegetation communities and have been checked for typographical and logical errors. Completeness_Report: All points were collected and analyzed Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The points were located using a military-style GPS receiver (PLGR), which has a published accuracy of 4-8 meters.

The resulting INFO file was exported into a text file, imported into a spreadsheet, and the attributes from the accuracy assessment and the spatial data were compared. If the attributes did not compare, an analysis of the mismatch was made and either the AA attribute or the map attribute was changed based on identification of the community on the aerial photo.

The upper levels of the hierarchy are based on the physical form or structure of the vegetation (physiognomy) and have been refined from the international standards developed by the United nations Educational, Scientific, and Cultural Organization (UNESCO). The two most detailed levels of the hierarchy are based on the species composition of existing vegetation (floristics) and reflect the phyto-sociological standards that were originally developed by European ecologists. The vegetation classification is continually advanced through the collection and analysis of new field data and will be greatly strengthened during the course of the USGS-NPS mapping efforts. Data file attributes include species, alliance, community element, and land cover. 01,Jack pine - black spruce / feathermoss forest (forest phase) 02,Spruce - fir / feathermoss forest 03,White cedar - boreal conifer mesic forest 04,White cedar - (mixed conifer) / alder swamp (open phase) 05,Black spruce / dwarf-shrub swamp complex 06,White cedar - (mixed conifer) / alder swamp (closed phase) 08,Maple - yellow birch - northern hardwoods forest (sugar maple phase) 09,Maple - yellow birch - northern hardwoods forest (mixed phase) 11,Red oak - sugar maple forest 12,Paper birch / bush honeysuckle - fir forest 13,Aspen - birch / boreal conifer forest (mixed aspen-birch phase) 15,Aspen - birch / sugar maple - mixed hardwoods forest (mixed phase) 17,Black ash - mixed hardwood swamp complex 18,Northern tamarack rich swamp 19,Balsam fir / paper birch forest 20,White spruce - balsam fir - aspen forest 21,White cedar - yellow birch forest (cedar - birch phase) 22,Jack pine - black spruce / feathermoss forest (woodland phase) 23,White spruce woodland alliance 25,Aspen - birch / boreal conifer forest (sparse canopy phase) 26,Common juniper rocky krummholz 27,Boreal rocky shrubland 28,Speckled alder swamp 29,Dwarf shrub fen complex 30,Poverty grass barrens 31,Bluejoint eastern meadow 32,Sedge meadow complex 49,Red maple - ash - birch swamp forest 50,Yellow birch - (spruce) forest 51,Boreal pine rocky woodland 53,Aspen - birch / boreal conifer forest (woodland phase) 54,Spruce - fir and sugar maple - yellow birch mosaic 55,Aspen - birch / sugar maple - mixed hardwoods forest (paper birch phase) 56,White pine - aspen - birch forest 60,Northern (laurentian) igneous / metamorphic moist cliff scrub 61,Great Lakes bedrock lakeshore 63,Great Lakes cobble / gravel lakeshore 67,Great Lakes bedrock lakeshore - (undifferentiated bedrock) 83,White cedar - balsam fir / leatherleaf / black crowberry krummholz 88,Canada yew mixed shrubland 90,Balsam fir woodland 98,Water 99,Urban/built-up 10A,Maple - yellow birch - northern hardwoods forest (yellow birch phase) 16A,Aspen - birch / sugar maple - mixed hardwoods forest (aspen phase) 16B,Aspen - birch / boreal conifer forest (aspen phase) 16C,Aspen - red maple forest 17A,Black ash (cedar) - mixed hardwoods swamp complex 19A,Balsam fir - aspen - paper birch forest 19B,Balsam fir / Canada yew - devils club forest 25A,Aspen - red maple rocky woodland 32A,Sedge / sphagnum meadow complex 50A,White cedar - yellow birch forest (mixed phase) 53A,Spruce - fir - aspen open forest 67A,Great Lakes cobble / gravel lakeshore - (undifferentiated gravel) Entity_and_Attribute_Detail_Citation: U.S. National Biological Survey, U.S. National Park Service, Department of the Interior November 1994, Accuracy Assessment Procedures, NBS/NPS Vegetation Mapping Program, Denver, CO, USGS, Biological Resources Division, Center for Biological Informatics, Prepared by: Environmental Systems Research Institute; Redlands, CA and National Center for Geographic Information and Analysis, University of California, Santa Barbara, CA and The Nature Conservancy, Arlington, VA under contract from U.S. Department of the Interior National Biological Survey and National Park Service. electronic document http://biology.usgs.gov/npsveg/aa/index.html Distribution_Information: Distributor: Contact_Information: Contact_Person_Primary: Contact_Person: USGS-NPS Vegetation Mapping Program Coordinator Contact_Organization: USGS/BRD, Center for Biological Informatics Contact_Position: Geospatial Technology Specialist Contact_Address: Address_Type: Physical Address Address: USGS Biological Resources Address: Center for Biological Informatics Address: Denver Federal Center, Building 810 Address: Room 8000, MS302 City: Denver State_or_Province: CO Postal_Code: 80225-0046 Country: USA Contact_Voice_Telephone: (303) 202-4220 Contact_Facsimile_Telephone: 303-202-4229 Contact_Facsimile_Telephone: 303-202-4219 (org) Contact_Electronic_Mail_Address: gs-b-npsveg@usgs.gov Distribution_Liability: The U.S. Geological Survey and the National Park Service shall not be held liable for improper or incorrect use of the data described and/or contained herein.
