Monster Seminar JAM - Shorebird Conservation in the Arctic National Wildlife Refuge
Dr. Stephen C. Brown
AbstractThe coastal plain of the Arctic National Wildlife Refuge is a critical breeding habitat for many species of waterbirds, including several species of shorebirds that are threatened by ongoing population declines. Breeding bird habitats may be significantly altered by proposed oil development, but the potential impacts are poorly understood because no complete survey has ever been conducted. We completed a survey of the entire Arctic Refuge coastal plain area that is potentially available for development (the 1002 area), using double sampling techniques that included detailed censuses of intensively studied plots, along with rapid surveys conducted at stratified sampling locations throughout the coastal plain. Detection rates by species were calculated from rapid survey data collected on intensive plots, where the actual number of nesting pairs was known. Our results document the distribution, diversity, and relative abundance of shorebirds and other waterbirds across the coastal plain of the Refuge. In addition, our results form part of the rangewide shorebird population estimates being derived as part of an arctic-wide international monitoring effort through the Program for Regional and International Shorebird Monitoring. Preliminary results suggest that the areas with highest value for shorebird habitat are clustered near the coastline, where the intensity of oil development would likely be the greatest.
