Researchers and hunters from the territories are heading to Yellowknife as part of an arctic wildlife conference.
The Arctic Ungulate Conference, set to begin next week, is held every four years and focuses on the management of northern species such as caribou, moose and bison.
More than 200 delegates from the territories and circumpolar countries are expected to attend.
"It's bringing people together who have the technical information and they will give presentations at this conference," said Drikus Gissing, director of wildlife management for the Government of Nunavut.
"There will be a lot of discussions about where to go with caribou management and learn from mistakes, and learn from other people around the world on how they manage caribou — and put technical heads together."
Among the topics the delegates plan to discuss is the drop in the caribou population.
The participants plan to discuss the drop in the numbers and the possible reasons for it, including the changing climate and the effects of exploration and development.
Gissing said extra monitoring is needed to help find out more about population trends.
"I expect that will be one of the hot topics that will be discussed. What impact does all the developments have that's taking place, especially in the Arctic regions now?"
Gissing said participants would look at what's happening in other regions and countries — what's working and what's not.
The conference will emphasize both a technical and traditional-knowledge approach to caribou management.
