Field data for the Vegetation Mapping Inventory Project of Great Sand Dunes National Park
2005-2008. Field data for the Vegetation Mapping Inventory Project of Great Sand Dunes National 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. To classify the vegetation, we sampled 603 representative plots and 208 observation points during the summers of 2005 and 2006 over the entire mapping area. Analysis of the plot data using ordination and clustering techniques produced 198 distinct plant associations, 22 of which are newly described. These associations were then combined into 51 vegetated map units. Other map units not derived from plot data include sparsely vegetated, non-vegetated, and various cultural features such as roads, urban and farmed lands. Accuracy assessment (AA) data were collected during the 2008 field season from late June to early October. Over the course of the summer, three two-person crews navigated to the randomly selected sample locations and documented the existing vegetation.
