What would happen if there were no cougars? Without the presence of cougars to check their growth, herbivore numbers increase to the point where they run the risk of consuming all the edible vegetation and preventing regrowth. As these plant species disappear, so do those species dependent on them for food, nesting sites, and other uses.
