“…The extent to which woodland caribou avoid human development is also dependent on the level of human activity (Dyer et al, 2001;2002). Higher energetics associated with industrial disturbance may also cause reduction in caribou mass depending on the cumulative influence of that activity (Bradshaw et al, 1998).…”

“…Reduction of use of high quality forage can also be a factor in decreasing tolerance of human activity through caribou displacement into poorer habitat resulting in lower fecundity (Nellemann & Cameron, 1998). Loss of functional habitat may also occur as a result of energetic consequences of disturbance from human development (Dyer et al, 2001;Oberg, 2001). The location densities and travel path distances relative to the 1 kilometre buffers suggest some loss of functional habitat along the road.…”

Abstract:The Owl Lake boreal woodland caribou population is the most southerly population in Manitoba. It is provincially ranked as a High Conservation Concern Population. Forestry operations exist in the area and there are plans for further forest harvest and renewal. The Happy Lake logging road is the only main access through the Owl Lake winter range. This logging road is currently closed to the public and access is limited to forestry operations during specific times of the year. An integrated forestry/caribou management strategy for the area provides for the maintenance of minimum areas of functional habitat. Habitat quality along the road was compared to habitat quality in the winter core use areas, within the winter range and outside the winter range. To evaluate the extent of functional habitat near the road, we conducted animal location and movement analysis using GPS data collected from January 2002 to March 2006. Habitat quality in the winter range, core use areas and along the road were assessed and found to be similar. Analysis of caribou locations and movement illustrate less use of high quality habitat adjacent to the Happy Lake Road. Loss of functional habitat is suggested to occur within 1 kilometre of the road. This potential loss of functional habitat should be incorporated into integrated forestry and caribou conservation strategies. Road management is recommended to minimize the potential sensory disturbance and associated impacts of all weather access on boreal woodland caribou.

“…The type and density of linear development within a local caribou range combined with the terrain conditions may or may not reduce the amount of available habitat as linear corridors represent a small fraction of habitat required for sustaining local populations. Studies have indicated that the avoidance of human developments increases as the level of activity increases (Dyer et al, 2001); however, low levels of human activity, such as those most commonly associated with transmission line ROWs, have also been found to cause avoidance of developments by caribou. Reduction in abundance of caribou in the vicinity of various human developments has been reported to range from 1 to 5 kilometers (Weir et al, 2007).…”

“…Caribou and wolves have been found to typically occupy different habitat types, creating a spatial and temporal separation between prey and predators, thereby reducing predation (James et al, 2004;Courbin et al, 2009). However, fragmentation of the boreal forest and avoidance of disturbances has the potential to concentrate caribou into progressively smaller areas of remaining habitat, which can make caribou vulnerable to predation (Dyer et al, 2001;Courbin et al, 2009). Boreal caribou exist at low densities compared to other boreal forest ungulates, thereby reducing predation risk as low caribou densities will not support predators in the absence of alternative prey (Thomas, 1995;Dyer et al, 2001).…”

Boreal caribou exist at low densities compared to other boreal forest ungulates, thereby reducing predation risk as low caribou densities will not support predators in the absence of alternative prey (Thomas, 1995;Dyer et al, 2001). Habitat conditions strongly influence the interaction between prey and predator (Peek, 1986), and spatial separation from other ungulates and conspecifics have been hypothesized as an anti-predation strategy of caribou (Thomas, 1995;James et al, 2004;Courbin et al, 2009).…”

Manitoba Hydro is responsible for the continued supply of energy to meet the needs of the province and is committed to protecting the environment when planning the construction and operation of its facilities. Corporate policy dictates ongoing improvement of Environmental Management Systems (EMS) in order to meet or surpass regulatory requirements. Environmental objectives are reviewed annually and programs are modified when necessary to address improvements in environmental performance. Manitoba Hydro plans and constructs major transmission projects throughout northern Manitoba which includes areas occupied by boreal woodland caribou. In recognition of the potential issues associated with hydro transmission construction in boreal caribou range, Manitoba Hydro hosted an expert workshop on May 8, 2007 to provide objective advice in the development of a draft corporate strategy that effectively directs targeted monitoring and research for environmental assessment and mitigation. The workshop focused on assessing the potential threats to boreal woodland caribou from a transmission line construction and operation perspective, and identifying appropriate approaches in site selection and environmental assessment (SSEA) and long-term monitoring and research. A total of nine threat categories were reviewed to determine the degree and magnitude of potential effects that may result from transmission construction and operation; and of the original nine, five final threat categories were delineated. The main elements of the workshop provided strategic approaches for proactive pre-construction monitoring, research on recruitment and mortality for local populations impacted by ROWs and control areas, and various habitat monitoring, management, and mitigation techniques. Research and monitoring priorities have been identified and continued collaboration with Manitoba Conservation and other land users were also identified.
