Field data for the Vegetation Mapping Inventory Project of Marsh-Billings-Rockefeller National Historical Park
2004-2005. Field data for the Vegetation Mapping Inventory Project of Marsh-Billings-Rockefeller National Historical Park
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. Thirty vegetation plots were sampled in the summer of 2004, covering the range of variation in the vegetation. Plot sampling included information on vegetation structure and composition and individual species cover by vegetation stratum and environmental setting. Seven plots were entirely new, and 23 existing forest plots established by Keeton in 2003 were re-sampled for understory vegetation. Analysis of the plot data and field notes allowed us to finalize the vegetation classification for the park and to map the vegetation onto an orthorectified composite aerial photo background using on-screen digitizing in 2005. Sixty-three accuracy assessment points were collected in 2007 to verify the accuracy of the 2005 vegetation map. The overall 2005 map accuracy and Kappa index was 76%, which fell below the USGS/NPS vegetation mapping protocol requirement of 80%.
