This is really interesting, but they're not carnivorous. The decaying salmon deposit nutrients in the soil. Carnivorous plants actually digest the insects directly for nutrients, usually because the soil is inhospitable.

Yeah, I think it's the absence of traits evolved to attract, trap, and digest salmon that are all missing here.

		I got really excited for a carnivorous salmon-fishing tree there for a second. I could envision how roots might evolve to jut into the water, and develop some one-way geometry that fish get trapped in.
