Wildlife use of disturbed habitats in arctic Alaska

Metadata Updated: May 10, 2018

In summer 1989, BP Exploration (Alaska) Inc. (BPX) and LGL Alaska Research Associates, Inc. (LGL) initiated a study of wildlife use of disturbed habitats in arctic Alaska. This study mapped selected disturbed sites and made observations of bird and mammal use of these sites over a 2-month period. The ultimate goal of this study over the next few years is to assess the impacts of gravel fill and man-made impoundments on the wildlife community and to collect information useful for rehabilitating habitats affected by these kinds of disturbance. Gravel fill is widely used in oilfield development and past work has substantiated that impounding of water upslope from the fill is common. But responses of wildlife to these changes is poorly documented. Qualitative observations made to date suggest that some animals avoid areas covered by gravel but that others might be attracted by the fill material. Likewise, there may be contrasting responses among wildlife species to impoundment areas; the few quantitative studies made suggest that response may also vary seasonally. To fill gaps in the existing data, we observed wildlife use of abandoned drilling pads and impoundments; and of tundra, river alluvium, and pond sites undisturbed by man for comparison. These sites were situated mostly in and near the Prudhoe Bay and Kuparuk oilfields on the Arctic Coastal Plain. The observations documented bird and mammal use by 3-min periods during 2-hr observation intervals from mid-June to mid-August. Observations were made on gravel pad, river alluvium, and undisturbed tundra sites that were roughly similar in size; and on impoundments and ponds of similar average sizes. The analyses calculated level of use of sites as average number of species per 2-hr interval and average number of individuals per 3-min period, and type of use as percent of total time animals were engaged in specific activities.
