Field data for the Vegetation Mapping Inventory Project of Chaco Culture National Historical Park
2004-2011. Field data for the Vegetation Mapping Inventory Project of Chaco Culture 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. During the summer of 2005, we sampled 141 representative plots located throughout the 16,615 ha (41,057 ac) of the main unit and environs of the park. Analysis of the plot data using ordination and clustering techniques produced 18 distinct plant associations, one of which was newly described. We included four riparian and shrub types, described in previous work in the main arroyo to arrive at 22 associations for the park. Field data were collected during the summer of 2005 when a total of 141 vegetation plots were established in the park. During the fall of 2006, a total of 315 accuracy assessment points were established. These data were used to develop the classification of the vegetation of CHCU, as well as verify the accuracy of the completed map. The accuracy assessment points served to alert the park to the presence of additional types that had not been identified during the vegetation plot sampling in 2005.
