powerful evidence of how the reintroduction of the predator changed the entire landscape of the environment...maybe that dude in Russia talking about how wooly mammoths helped preserve permafrost wasn't so stupid after all if humans would just get out of the way one day, hopefully the planet can heal itself Reintroduced Wolves Caused A "Trophic Cascade", Transforming Yellowstone's Ecosystems But when wolves were reintroduced in the 1990s, the predators not only reduced the elk population but also caused them to change their grazing habits – forcing them to become more cautious and avoid open environments. This allowed the surrounding vegetation to grow, which then attracted more diverse species of birds and insects. The regrowth of plants and trees has been so powerful that it has even caused rivers to move as riverbank erosion slowed down, leading to less meandering and allowing channels to deepen and small pools to emerge. This, in turn, eventually changed the geography of the surrounding area. The impacts of trophic cascades, therefore, have incredible influences on all aspects of the wider ecosystem, changing biodiversity, primary productivity, and even the nutrient cycle. Although trophic cascades and their startling effects have been of ecological interest for some time, this new study is the first to quantify its strengths by focusing on riparian willow volume. It uses these trees as a proxy for aboveground biomass, showing a distinct and significant three-dimensional recovery of streamside vegetation measured by the growth of both crown area and height among the willows.
