A key component of the early permitting process for our Willow Development, located in the northeast portion of the National Petroleum Reserve – Alaska (NPR–A), was extensive environmental baseline studies conducted in 2017.
Avian surveys found nine yellow- billed loon nests, and spectacled eider surveys documented the distribution and abundance of eiders in the project area prior to nesting. Survey information is valuable as yellow-billed loon nests may require a buffer from development-related infrastructure.
Over 100,000 acres of the study area were also mapped using an Ecological Land Survey method that examines geomorphology, surface form, vegetation, ecotype, and wildlife habitat. 213 vegetation plots were established, and approximately 200 vascular plants and 80 non- vascular plants were encountered, including three rare plants. Fish abundance and distribution surveys in the study area captured, identified, measured, and released over 6,500 fish representing 10 species. Fish over seven inches were tagged during 35 days of fish sampling and spawning was identified in four Judy Creek tributaries. Hydrology surveys established 21 water level monitoring stations and two telemetry stations for remote monitoring of water levels, which reduces helicopter traffic. Many of these studies are ongoing to support long-term environmental monitoring.
These baseline studies help inform engineering design and facility location in order to avoid or minimize environmental impact.
