Barren-ground

Barren-ground caribou are larger in size than the Dolphin and Union and Peary caribou. The average bull (male caribou) weighs in at 100 to 140 kg (220 to 309 lb). Females weigh less. In summer they eat grassy plants, shrubs and mushrooms, and in winter they mostly eat lichens. 

These caribou are mostly migratory, often forming large herds that can number in the hundreds of thousands. They migrate twice a year, moving to calving grounds on the treeless tundra near the coast in springtime, and back towards the treeline in the fall. The top two herds (the Bathurst and Porcupine herds) travel about 1,350 kilometers (as the crow flies) between their summer and winter ranges. When migrating, they walk at about 7 km/hr, covering between 20 and 65 km a day. Smaller herds that are less migratory also exist. Some of these are found on islands such as Southampton Island and Coats Island, two large islands in the northern part of Hudson Bay.

The largest herd in Canada currently is likely the Qamanirjuaq herd that ranges between Nunavut, the Northwest Territories, northern Manitoba and Saskakatchewan. It was estimated to number 288,000 animals in 2017. Overall, the numbers of barren ground caribou are declining. The Bathurst herd that currently ranges between the NWT and Nunavut may have fallen the furthest from a high of 472,000 in 1986, to an estimated 8,200 in 2018

That’s a decrease of more than 98%. Two populations appear to be bucking the trend of general decline. The Porcupine caribou herd was at a record high of 218,000 in 2017.

The causes of the declines are discussed in more depth in the “threats” section and may be different for different herds, but there is a significant opinion that development of mining and infrastructure (particularly roads) within the range of some of the herds facing the steepest declines is a contributing factor. Hunting pressure and predation are other significant factors identified. As the NWT Species at Risk assessment for Barren-ground caribou notes, “Most barren-ground caribou herds are now at low points in their abundance and they are facing cumulative effects from multiple interacting threats that are unprecedented.”

The steep decline of some of these herds has led to a moratorium on hunting some of the declining herds. For instance, in 2015 the NWT government created a Mobile Core Bathurst Caribou Conservation Area in which no caribou hunting is allowed. The moratorium on hunting has caused hardships to local people who are heavily dependent on the caribou for food, and are forced to buy often expensive (and relatively unsatisfying) food from local stores instead. In addition to the costs of the replacement food, the lack of caribou in the diets of Indigenous people can also lead to spiritual and cultural impacts.

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."

The paper notes that, "...the ability to access preferred calving areas and the ability to synchronize births in time are critical for maintaining high barren-ground caribou abundances..." in concludes, "Overall, we detected considerable variability across years and across herds, but no significant trend for earlier calving by caribou, even as broad indicators of spring and snow phenology trend earlier."

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.

The authors suggest that adjusting traffic levels and frequencies might help mitigate the effect on caribou.

The report concludes that: "Levels of most contaminants measured in caribou tissues are not of concern, although kidney mercury and cadmium concentrations may cause some concern for human health depending on the quantity of organs consumed. Caribou meat (muscle) does not accumulate high levels of contaminants and is a healthy food choice. Concentrations of PFASs and PBDEs are low with respect to potential toxicity to caribou or those consuming caribou. Adults consuming Sanikiluaq reindeer are recommended to consume a maximum of seven whole livers each year due to PFOS levels in those livers."

Yukon Health has advised restricting intake of kidney and liver from Yukon caribou, the recommended maximum varying depending on herd (e.g. a maximum of 25 Porcupine cariboukidneys/year).

With the help of local hunters, we have been taking kidney, liver and muscle samples of Qamanirjuaq caribou since 2006. We collect these samples to study changes in the levels of contaminants in kidneys and livers of caribou. These contaminants may be carried to the Arctic by wind.

Human disturbance effects and cumulative habitat loss in endangered migratory caribou

A 2018 academic paper to assess the effects of human disturbance on barren-ground caribou herds. This study focuses on the Leaf River and George River herds in northern Quebec and Labrador. The paper finds caribou do avoid human disturbance but makes no findings on the impacts to the health of the two herds

Inuit Approaches to Naming and Distinguishing Caribou: Considering Language, Place, and Homeland toward Improved Co-management

An academic paper describing how the people of Uqsuqtuuq (Gjoa Haven) in Nunavut describe different sorts of caribou. These don't match up with how biologists describe the herds. The authors suggest that a better understanding of how local people describe caribou would help in management of the herds.

It classifies the Porcupine caribou as “not at risk” in the NWT, and the other herds as “threatened” within the NWT. The assessment contains parallel tables that compare Indigenous and scientific knowledge on aspects of the caribou.

Review of post-2010 Literature on Human Effects on Barren-Ground Caribou: Focus on Traditional Knowledge, Western Science and Caribou Protection Measures

This 2015 report prepared for the Nunavut Wildlife management Board reviews both scientific and traditional knowledge sources published from 2010-2015 on the effects of human disturbance on barren-ground caribou. It is organized by looking at linear features (such as roads, power lines and pipelines), resource development infrastructure (such as buildings or open pit mines), and aircraft and vehicles. It concludes that, “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.”

Cadmium in caribou and muskoxen from the Canadian Yukon and Northwest Territories

Cadmium, zinc, copper and metallothionein concentrations were measured in liver and kidney tissue of caribou and muskoxen collected from various sites in the Canadian Yukon and Northwest Territories. Cadmium concentrations in caribou tissues were substantially higher than in muskoxen for all age classes and were comparable to concentrations reported for caribou from northern Quebec and Norway.
