註釋The declines in caribou populations between 1996 and 2006 aroused considerable concern in NWT communities because caribou have been a resource of great value to people in the north for many generations. Possible explanations for the declines include: a natural cycle, variation in weather and forage conditions, predation, hunting, disease, and industrial development. Of these factors, some are beyond immediate control, but effects due to direct human influence, like hunting and development, can be managed. 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 over time that affects caribou numbers and distribution. Concerns over effects of development on caribou have been raised in environmental assessments, particularly by Aboriginal groups, for many years, but progress on assessing them has been limited. To be objective, assessment of cumulative effects must account for other factors, including hunting and natural variation in weather.
