The goal of the study is to obtain sufficient population information on caribou to use in evaluating Susitna-Watana Hydroelectric Project-related effects and identifying any necessary measures to avoid, minimize, or mitigation for those effects. The study would cover the Nelchina and the Delta caribou herds.
Sufficient population information on caribou is needed to evaluate effects of the proposed Susitna-Watana Hydroelectric Project on important seasonal ranges, such as calving areas, rutting areas, wintering areas, and migration/movement corridors. The Nelchina caribou herd and Delta caribou herd will be studied in an area that includes most of Game Management Unit 13E east of and including Broad Pass, and will include also drainages empting into the upper Susitna River and the northwestern portion of Game Management Unit 13A, and areas on the south slope of the Alaska Range outside the Susitna basin. The study supplements ongoing ADF&G caribou research in the study area and surrounding region by increasing the sample size of radiocollared caribou from both the Nelchina caribou herd and the Delta caribou herd. Telemetry and GPS locations from these radiocollared caribou are being used to document the seasonal use of and movement through the Project area by both females and males of both herds, to document the extend of herd mixing between the two herds, to document productivity and survival of caribou using the Project area, and to compare current movements and distributions in the Project area to historical data. This draft document details Alaska Energy Authority's status in implementing the study as set forth in the FERC-approved Revised study plan.

The Bathurst caribou distribution was examined by satellite collar and aerial survey during the summer post-calving season. The focus was on distribution relative to three diamond operations and in regard to weather, vegetation classification, insect abundance, plant productivity. The analysis suggests a trend of increasing caribou movement from the Ekati and Diavik mine site vicinities and selection of habitat at further distances from these mine sites over time.
This book identifies accumulated environmental, social and economic effects of oil and gas leasing, exploration, and production on Alaska's North Slope. Economic benefits to the region have been accompanied by effects of the roads, infrastructure and activies of oil and gas production on the terrain, plants, animals and peoples of the North Slope. While attempts by the oil industry and regulatory agencies have reduced many of the environmental effects, they have not been eliminated. The book makes recommendations for further environmental research related to environmental effects.
