Field data for the Vegetation Mapping Inventory Project of Hubbell Trading Post National Historic Site
2006. Field data for the Vegetation Mapping Inventory Project of Hubbell Trading Post National Historic Site
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. HUTR collected vegetation and environmental data in selected polygons on August 15 and 16, 2006. The field survey extended outside the HUTR boundary into the project-defined environs. Given the small size of HUTR, and the subsequent low probability of finding new associations, we decided against using a formalized data collection process, and, instead, used an abbreviated protocol. We used an “observation point” form to collect enough data to assign an existing vegetation association to a particular plot. Prior to the field visit, all polygons were assigned an identification number. While the field crew tried to visit each polygon, it was not possible to visit all polygons, due to time constraints. So the field crew concentrated on the larger and more ecologically interesting polygons. At each polygon that we visited, we 1. established an observation point within the visited polygons and collected data on the observation point forms. 2. took four photographs at each observation point, facing each of the cardinal directions. (Due to camera problems, some visited polygons do not have digital photographs associated with them.) 3. recorded notes on the vegetation structure and composition within polygons. Each reference note directly corresponded to one or more polygon identification numbers. The majority of reference notes described vegetation alliances or associations that had previously been sampled in the project area at observation points. Using a combination of observation points and informal reference notes, the field crew recorded information on a majority of the polygons in the project area. All observation point data, as well as point files associated with the GIS database, are included in the attached Microsoft Access database
