Sand Creek Massacre National Historic Site: Vegetation Classification and Mapping, A Report for the

As a newly acquired parcel, National Park Service (NPS) Southern Plains Network initiated a vegetation classification and mapping project as one of many on-going projects to gather baseline data to inform land management decisions and planning. Following the protocols of the USGS - NPS Vegetation Mapping Program, the Colorado Natural Heritage Program (CNHP) performed a two-year project to classify and map the vegetation at SAND. The project was initiated in the spring of 2005 and vegetation data for classification and mapping were collected during late summer of 2005. The vegetation classification, field key, and local plant association descriptions were completed and written during the winter of 2005 - 2006. Accuracy assessment data were collected over the summer of 2006 and assessment of the vegetation map accuracy was completed in the winter of 2006.
