Salmon Ecosystems and Mining

Selected Scientific Literature

The Nature Conservancy seeks to understand the level of risk posed by proposed large-scale mining in the Nushagak and Kvichak headwaters.

A large-scale copper and gold mine proposed for Alaska's Bristol Bay headwaters warrants a thoughtful risk analysis. The scientific community has addressed issues associated with large-scale mines, such as acid mine drainage, the effects of heavy metals such as copper on wild salmon and the status of water reservations in Alaska.
