One species of urchin, tripneustes gratilla, was bedded in a 1/4 m2 plot with > 50% kappaphycus cover. Fences were made out of plastic coated chicken wire and were surveyed every month with photoquadrats to assess kappaphycus abundance. In addition, regrowth of plots where kappaphycus had been removed was monitored. To assess the potential to use native sea urchin's as biocontrols for alien/invasive seaweeds and to monitor the regrowth of Kappaphycus.
