Every summer they return to spawn in the rivers in which they were born. I found two deep pools at the base of a small waterfall alive with pink salmon preparing to leap the cascades and continue their upstream migration. Here I wedged myself into a crevice - the only way I could hold my position in the freezing fast-flowing water. Salmon bring life not just to seals bears and wolves but also to the rainforest trees which assimilate nutrients from the fish once they have died after spawning. January 2011 BBC Wildlife .
