Human disturbance

The impact of human disturbance on caribou is one of the most contested issues in the study of caribou. By human disturbance, we mean things like industrial impacts (such as mining or oil and gas installations), the development of infrastructure such as roads, ports, and pipelines, and the presence of people generally, such as tourists. 

A large scale 2018 study on two barren-ground caribou herds in Northern Quebec and Labrador found that caribou did avoid many types of disturbance. The effect was different for different types of disturbance.  The avoidance stretched as far as 23 km for one herd avoiding a mine site. In the case of power lines, there was usually no apparent avoidance. Roads were found to pose a barrier on some occasions, but on others, were crossed by caribou. The study found that overall, human disturbance was affecting where caribou chose to go, but it could not conclude that this would have a negative effect on the herds.

Other studies have included information from Indigenous knowledge sources that also suggest that human disturbance, particularly industrial disturbance, is responsible for caribou avoiding certain areas. A report prepared for the Nunavut Wildlife Management Board in 2015 concluded, “ The impact of development on caribou is usually not due to single roads, mines, cut-blocks or seismic lines; rather, it is the cumulative effect of many habitat alterations including disturbances over time that affects caribou numbers and distribution.”

Nunavut Impact Review Board Issues Reconsideration Report and Recommendations for Agnico Eagle Mines Limited’s “Meliadine Extension” Project Proposal, related to the Meliadine Gold Mine Project

A news release from the Nunavut Impact review board giving its reasons for turning down a request for a gold mine extension in Nunavut. The request from the Meliadine gold mine north of Rankin inlet would have added 11 years to the mine life, according to the mine owners. The review board highlighted potential effects of the mine expansion on the Qamairjuaq caribou herd and the people who rely on the herd; "...the Board noted high levels of uncertainty as to whether existing or modified mitigation measures would be sufficiently protective to prevent or manage negative effects from the Extension Proposal on caribou; especially when considering critical calving and post-calving periods. The Board also acknowledges that unpredicted negative impacts on caribou would have immediate negative effects on the ability of Inuit, Dene and Denesuline reliant on this herd to harvest caribou, which could have devastating and lasting effects on livelihood, health and culture."

Shifting trails: the shrinking range of Bathurst Caribou

An excellent new web-based resource including maps and multimedia that gives a clear description of the challenges faced by the endangered Bathurst caribou herd, and the impacts of the herd's decline on the Tłı̨chǫ. The Tłı̨chǫ are a first nation whose territories to the north of Great Slave Lake overlap with the wintering range of the Bathurst herd. This site is a good case study of the challenges facing this herd and other barren ground caribou herds.

Effects of vehicle traffic on space use and road crossings of caribou in the Arctic

This academic paper examined the influence of traffic volume on how caribou in Alaska's Central Arctic Herd used their summer range and road crossings. The area studied is crossed by roads to service two oil fields on the North Slope. Previous sudies had suggested that 15 vehicles per hour was the level at which the caribou tended to avoid roads areas and road crossings, but the new study suggests that use of areas near roads picks up when traffic is less than 5 vehicles per hour. The study also fund that insect harassment seemed to be a factor too - when insect harassment was higher, caribou were less likely to be deterred by roads and traffic.

Why didn’t the caribou (Rangifer tarandus groenlandicus) cross the winter road? The effect of industrial traffic on the road-crossing decisions of caribou

An academic article (not open access) that reports on a study that monitored the behaviour of collared caribou next to a winter road in the Northwest Territories used for mine access. The study found, "Caribou rarely crossed the road when any level of traffic was present; the level of traffic, not the road right-of-way, was the underlying explanatory factor for that behavioural decision." The authors suggest that adjusting traffic levels and frequencies might help mitigate the effect on caribou.

Caribou and wind turbines (Kivalliq region) - an overview of available information

A 22 slide presentation (exported as a pdf) providing an overview of effects of wind turbine development on Caribou. As the presentation points out, there is little information directly on the effects of wind turbines, so a lot of the information covers the effects of potential related disturbance. The presentation is related to plans to install wind turbines in the Nunavut communities of Baker Lake, Arviat and Rankin Inlet. The presentation was the result of a project by Heather Hayne for WWF Canada.

The Effect of Traffic Levels on the Distribution and Behaviour of Calving Caribou in an Arctic Oilfield

14 page (without reference list) academic journal article on the effects of traffic and infrastructure on the behaviour of calving caribou from the Central Arctic (barren ground) herd in Alaska. The paper concludes, "some behavioral disturbance and displacement of maternal caribou during calving still occur with convoying of traffic and low traffic frequency. Convoying may reduce the amount of displacement during periods between convoys, which could improve crossing success."

Update on the global status of wild reindeer and caribou

This online article gives a relatively brief overview of the status of wild caribou and reindeer around the circumpolar world. There are some bright spots, but, "At the global scale, the historical trend continues with declining abundance and contracting distribution for most Rangifer populations." The global population of wild caribou and reindeer is estimated ar 2.43 million, down from 2.8 million in 2016.

Evaluating the impact of caribou habitat restoration on predator and prey movement

An academic paper that looks at the impact on caribou numbers of trying to return seismic lines back to a more natural state. The research found that restoration on seismic lines in northern Alberta slowed wolved and caribou. The assumption is that if both wolves and caribou move more slowly along these sites, it will reduce the likelihood that they run across each other, and so reduce the numbers of caribou killed. The paper suggests further research to test that assumption.

Government of Canada invests $3.8 million to support barrenground caribou conservation in the Northwest Territories

A news release from the Canadian government department of Environment and Climate Change announcing an investment in three caribou projects of $3.8 million, to be matched equally by the government of the Northwest Territories. the releqase says the projects, "will monitor barren-ground caribou, their habitats, and threats that may be affecting herds in the Northwest Territories by using Indigenous and Western science and knowledge. Projects also aim to conserve and protect barren-ground caribou populations and their habitats by working to minimize human and predator impacts, and identifying important barren-ground caribou habitats such as calving grounds and migratory routes for conservation." The release doesn't mention the exact nature of the projects, or the period over which the money will be paid out.

Trophic consequences of terrestrial eutrophication for a threatened ungulate

This academic paper looks at the relationship between increased productivity in forests, woodland caribou, wolves, and other prey species such as moose and deer. The greater productivity of forest floor plants caused by cutting down older trees encourages more moose and deer, which in turn bring more wolves that prey on caribou.

This academic article combines Indigenous and scientific knowledge to elaborate on the histroy of caribou movements near the Dënesǫ́łıné community of Lutsel K'e (Northwest Territories). It is useful to not only consider the abundance history of the Bathurst and Beverly caribou herds, but also the ways in which the research was locally-directed, and the ways in which the different types of knowledge were used. The paper repeats the contention of local people that disruption caused by mining in the region is largely to blame for the current herd declines.
