Urchin Barren

An area where the absence of fleshy seaweeds on hard substratum is attributed to over-grazing from sea urchins. These areas are largely devoid of fleshy macroalgal cover where seaweeds would otherwise be expected to occur, and sea urchins are typically present at high densities, although once formed an urchin barren can be maintained by relatively low densities of urchins.
