December 19, 2018 — Catching chinook salmon today requires gear, technique, experience and luck. Catching salmon a year or a decade from now requires science.
That means local science. The recent National Climate Assessment notes that Alaska’s temperature has been warming at twice the global rate. To get at what this means for Alaskans, we need University of Alaska scientists.
Alaskans are getting a better handle on what a warming world does to salmon runs through the work of a federally funded corps of local fisheries researchers based at the University of Alaska Fairbanks. Known as the Alaska Cooperative Fish and Wildlife Research Unit, its researchers address climate questions from an Alaska perspective.
For example, they research how melting glaciers can increase or diminish salmon numbers and for how many years. They consider how the increasing frequency of wildfires plays out on salmon streams. They compare how the same conditions can have different effects on sockeye, coho and chinook salmon.
It’s not the gloom and doom of a planet in peril. In some ways, climate change appears to have boosted some salmon counts, at least temporarily.
An accurate salmon count depends in part on a good scientist count. Here, the news is not good. Until I hired Alaska assistant unit leader Abby Powell to come run the University of Florida Cooperative Fish and Wildlife Research Unit three years ago, the Alaska unit had five faculty members. It’s down to two.
Slowly starving for lack of federal funding, Alaska’s fish and wildlife species science is itself becoming an endangered species.
The national Cooperative Fish and Wildlife Research Unit (CRU) program was established in 1935 on the premise that science, not politics, should guide management of national treasures such as eagles, bison, and moose. An administration proposal to de-fund it does away with that premise.
