Poor Knights Islands
In 1981, a marine reserve was set up around the Poor Knights Islands, extending 2,600 ft (800 m) out from the shore. The area is popular with divers for its caves and kelp forests. In the most exposed places, the kelp Lessonia variegata is predominant, while at more sheltered sites Ecklonia radiata is more abundant, together with the large brown seaweed Carpophyllum flexuosum. Large numbers of sea urchins dominate in some places.
