Ecological Restoration and Land Rehabilitation
land reclamation at the ekati diamond mine, northern
territories, canada. (1995–2005)
Client: BHP Billiton, Inc.
ABR provided a preliminary reclamation research
program for the EIS prepared for the mine, and developed
a long-term reclamation research program that involved
conducting a variety of experiments testing top-dressings
and different plant materials for promoting revegetation
of mine disturbances. Tasks included overseeing
fertilization, seeding, and planting efforts; monitoring
of soil and vegetation response in reclaimed areas;
and assessing the potential of local plant species
for use in revegetation. ABR also provided recommendations
and implemented revegetation plans for abandoned
sites and wrote a review of performance criteria
to be used as part of the evaluation of mine reclamation
at closure. For more information, contact Janet

LAND REHABILITATION STUDIES IN THE KUPARUK OILFIELD,
ALASKA. (1989–present) Client: ConocoPhillips Alaska, Inc.
ABR is conducting a number of long-term land rehabilitation, revegetation, and bioremediation projects in the Kuparuk Oilfield, on Alaska’s North Slope. Many of these projects focus on rehabilitation of gravel substrates, the most common surface disturbance on the North Slope. Studies are testing revegetation and bioremediation techniques at sites of small spills of oil and brine. Use of sewage sludge to amend gravel substrates for enhancement of revegetation is being studied. Several experimental plots are being monitored to determine the relative efficacy of different combinations of fertilizer, soil amendments, and the long-term survivorship of various native plants cultivars. Wetland creation techniques are being evaluated at experimental sites (created ponds) and at natural tundra areas revegetated with aquatic grasses.

BIOREMEDIATION AND TUNDRA RESTORATION AT A CRUDE OIL SPILL SITE IN THE KUPARUK OILFIELD, NORTHERN ALASKA. (1990–1994)
Client: ConocoPhillips Alaska, Inc.
participated in the cleanup of an old (ca. 1969–1970)
oil spill at an exploratory drill site (S.E. Eileen)
along the Kuparuk River in northern Alaska.
The cleanup required a detailed agency-approved
remediation plan incorporating both off-site incineration
and in-situ bioremediation. Site
assessment delineated the extent and level of contamination
and identified what hydrocarbon constituents remained.
Plant cultivation efforts focused on restoring wetland
vegetation. In-situ bioremediation
resulted in 90% reduction in hydrocarbon levels.
ABR assisted ARCO in site closure negotiations with
the Alaska Department of Environmental Conservation.

ECOLOGICAL RESTORATION OF abandoned oil field
facilities and exploratory well sites, north slope,
ALASKA. (2000–present)
Client: BP Exploration (Alaska), Inc.
ABR is involved in a long-term North Slope land
rehabilitation program that includes preparing and
implementing rehabilitation plans for facilitating
the establishment of arctic wetland and upland plant
communities on oil field disturbances. The program
involves developing revegetation performance standards;
providing recommendations for enhancing the wildlife
characteristics of rehabilitated areas; identifying
and applying appropriate plant materials; monitoring
soil and vegetation response; and monitoring the
surface and thermal stability of rehabilitated sites.
