The study area (Figure 1) includes both the Denali block (4.5 million acres) and the Tiekel block (507,000 acres) of BLM administered land. Included within the Denali block are the Gulkana Wildlife Habitat Area (WHA) (1.1 million acres) (Appendix 1) and the Delta WHA (72,000 acres) (Appendix 2). These two areas were inventoried for bald eagle nests in the summer of 1981. Descriptions of the study areas can be found on the write-up of the 1981 BLM survey.
