Alaska is about to get thousands of miles of new salmon habitat — and how we manage that habitat will have long term implications for the salmon that find it.

By the year 2100, melting glaciers will open up new watersheds containing thousands of miles of salmon habitat across Alaska and the Pacific Northwest, according to an aptly titled scientific paper, “Glacier retreat creating new Pacific salmon habitat in western North America,” out recently in the journal Nature Communications.
