Landbird monitoring in Denali National Park and Preserve, 1998 annual report
Benson AM and Springer SK. 1998. Landbird monitoring in Denali National Park and Preserve, 1998 annual report. Alaska Bird Observatory. Fairbanks, AK
The Alaska Bird Observatory monitored landbirds for seventh consecutive breeding season (1992-1998) in Denali National Park and Preserve. They used on-road and off-road point counts to monitor avian populations. Nine off-road routes and two on-road routes surveyed from 1993-1997 were repeated in 1998, and two off-road routes were added in alpine tundra and riparian habitats. Two previously surveyed on-road routes were not surveyed in 1998 because they overlap with Denali National Park's Breeding-Bird-Survey routes. As in previous years, species richness was greatest near the west portion of the park, and frequency of occurrence of most species remained relatively constant among the years. To determine the status of avian species nesting in the park, we recommend long-term monitoring in stratified habitat types and developing cause-and-effect relationships for landbird population by analyzing annual productivity relative to population indices.
