The millions of salmon that return to and decay in countless streams provide nitrogen and other nutrients essential to plants, trees, animals, and insects.
In fact, the salmon runs of Alaska and the Pacific Northwest serve as what some scientists call a biological “power cable”.
Bears are one link in the power cable system, since they eat tons of salmon and excrete nutrient-filled scat all around the forests where they roam.
You can see the start of that nutrient flow courtesy of a web cam installed at Brooks Falls in Katmai National Park & Preserve, Alaska ... about 300 miles southwest of Anchorage.
Don’t expect to see anything after sunset or before sunrise!
