The Boreal Caribou Ecological Model
Developed by the Habitat Restoration Working Group (HRWG) of the National Boreal Caribou Knowledge Consortium (NBCKC).
Habitat restoration is expected to play a key role in the recovery of boreal woodland caribou (Rangifer tarandus caribou) in Canada. Population declines are correlated with the proportion of ranges affected by anthropogenic and natural disturbances and reversing these impacts is expected to benefit caribou populations. However, there are various mechanisms that lead from habitat stressors to caribou declines, and the effects of these mechanisms differ among ranges.
Understanding the ecological pathways driving observed relationships can inform restoration planning by:
- directing treatments towards the most critical, range-specific mechanisms;
- identifying possible confounding factors that need to be addressed; and,
- supporting adaptive management by generating testable hypotheses and clarifying monitoring needs.
Here we present a conceptual Boreal Caribou Ecological Model developed by the Habitat Restoration Working Group of the National Boreal Caribou Knowledge Consortium. The model is composed of 14 factors and associated relationships that generate pathways leading from a variety of landscape disturbance stressors. The model does not capture all possible factors in the system, but only those that are likely exerting significant effects. Nor does it address specific restoration treatment options but it can inform the design of treatments by identifying the functional effects that treatments should be addressing.
Caribou survival and recruitment are affected directly by predation, nutrition, disease and hunting. All of these link back to one or more habitat stressors that drive the national disturbance model (i.e., fire, insect pests, forest alteration/clearing and linear development). The individual relationship pathways interact with each other and can also be affected by external factors. The habitat stressors alter forage available to caribou and to other primary prey, the distribution and abundance of primary prey, associated predators and of humans, and ultimately cause population declines via lower caribou survival and reproductive success.
A key next step for the conceptual model is the development of appropriate response metrics to monitor response to restoration efforts. This would provide the means to compare the relative effects of different drivers among ranges and would highlight key knowledge gaps. The model would then provide a complete framework for adaptive management as habitat restoration is implemented.

Science and Indigenous Knowledge to Predict Changes in Caribou Habitat
To provide essential knowledge for improving woodland caribou recovery plans, the Canadian Forest Service initiated an integrative research project in collaboration with the Pessamit Innu community (QC North Shore). This community is very concerned about caribou and has carefully monitored populations across their ancestral territory, the nitassinan, in recent years
The project has six interrelated components that integrate science and indigenous knowledge:
-
Mobilizing scientific and indigenous knowledge and add the community’s perspective to inform the North Shore caribou recovery plan
-
Prediction of disturbance, climate change and forest management impacts on caribou habitat quality
-
A decision support tool for caribou and its habitat in northern Ontario
-
Development of genomic tools to characterize the caribou diet and microbiome from feces
-
Assessing the potential of caribou as an umbrella species for maintaining biodiversity
-
Assessing food habitat quality of different forest types
