In northwestern North America, a new rush of mining exploration and production is underway. The valuable mineral reserves in this region underlie watersheds that support critical water resources and cultural keystone species such as Pacific salmon. The scale of current-day mines dwarfs many historical mines. And, despite improvements to modern-day governance processes, we still witness mining operations causing harm to salmonid-bearing watersheds. This presentation will describe the basics of industrial-scale mining operations, the ecology of salmonid-bearing watersheds, and the negative impacts that metal and coal mining can have on salmonids and their habitat. This information can be applied to four key scientific questions intended to promote transparent discussions of whether the risk and uncertainty of mining impacts are sufficiently considered in governance processes.
