I would characterize the main threats to habitat as mining—mineral extraction, both hard rock and placer mining—hydro development, and to some degree linear development, so roadways.
Yukon government, Fisheries and Oceans Canada, and the Council of Yukon First Nations agreed some years ago to develop a new system for managing placer mining in the Yukon, but in particular the impacts of placer mining on fish. Just to clarify, because I'm sure people are wondering what placer mining is, it's a kind of gold mining that doesn't use chemicals. It uses water and gravity to extract gold, usually from stream beds. It tends to be a little bit more small-scale than the giant mines or open-pit mines that you've probably seen pictures of, but tends to be working directly in or nearby fish habitat.
That system...[Technical difficulty--Editor]...in place now for a number of years.
