Investigations in and near Denali National Park and Preserve (DENA), Alaska, had as their major objectives: (1) establishment of baseline information on selected native vegetation and the organic-rich Oa soil horizon of the study area; and, (2) definition of current element areal trends, if any, of the area, possibly resulting from anthropogenic influences such as power-plant emissions. These objectives were accomplished by establishing two generally east-to-west traverses (The Control and Stampede Traverses), one north-to-south Traverse (the Nenana River Traverse), and twelve additional sites at various strategic places in or near DENA. Traverse sample localities were positioned at geometric intervals starting near the existing Golden Valley Electric Association (GVEA) power-plant located in Healy. At each locality, samples were collected of Hvlocomium splendens (Hedw.) BSG (feather moss, whole plant, including rhizoids), Peltiaera aphthosa (L.) Willd. (lichen, whole plant), and the Oa soil horizon. Picea glauca (Moench) Voss. (white spruce, twigs and needles), was also collected at selected sites. All materials were analyzed for their major and trace total element concentrations. This report is the result of a cooperative study between the National Park Service (NPS) and the U. S. Geological Survey (USGS). A product of this study will be providing the information so that an assessment of the potential for any effects to the biological resources of DENA from air pollutants to be emitted from the proposed Healy Clean Coal Project (HCCP) power-plant can be made.
