If sea otter populations decline, sea urchin and other prey species populations increase and graze on more of the kelp forestsoften to the point of destroying them. Animals can hide from predators in marsh vegetation, because the shallow brackish area physically excludes larger fish. Consequently, both sea urchin species may thrive during future warm summers and may enhance their top-down control on local macroalgal populations.
