Abstract
Destruction of kelp beds by sea urchins [Strongylocentrotus droebachiensis] has been documented in St. Margaret''s Bay, Nova Scotia, and also appears to be taking place in other parts of E Canada. Continued sea urchin settlement onto grazed areas prevents the return of kelp [Laminaria longicruris and L. digitata] and other algae for long periods. Because of the large contribution of kelp beds to coastal productivity, the disappearance of kelp from large areas is alarming. Dynamics of sea urchin grazing are discussed.This publication has 2 references indexed in Scilit:
