Caribou Crossing and Pipelines in the Prudhoe Bay Area: Historical Research

This record contains links to two reports describing research associated with caribou crossing success and infrastructure.

1) Permitting for the Endicott Development Project required monitoring of the effects of the project. A caribou monitoring element of the program was conducted during the summers of 1987-90 on the Sagavanirktok River delta at the eastern edge of the Prudhoe Bay oil field. The goal of the caribou study was to assess the effectiveness of crossing structures in accommodating movements by caribou. The report summarizing this monitoring is provided as download and can be cited as:

Lawhead, B. E., L. C. Byrne, and C. B. Johnson. 1993. 1990 Endicott Environmental Monitoring Program final report, Volume 5: Caribou synthesis, 1987–1990. Prepared for U.S. Army Corps of Engineers, Alaska District, Anchorage, by Alaska Biological Research, Inc., Fairbanks, Alaska, USA. Edited by J. Clarke and J. D. Miller, Science Applications International Corporation, Anchorage, Alaska, USA.

2) A review was undertaken to revisit the issue of pipeline height in relation to caribou crossing success and to assess the applicability of existing information to answer questions regarding best practices. This report focuses specifically on the issue of pipeline height in relation to crossing success, rather than on a broader evaluation of the response of caribou to linear developments. Citation of this report is:
