Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. The country’s largest kelp is Macrocystis pyrifera, known as bladder kelp in New Zealand, but giant kelp elsewhere. While the most effective way of doing this is by reducing carbon emissions, experts increasingly think that this will not be enough. With a height of up to 50 metres or more, it provides a rich habitat for small creatures such as lace corals, sea snails and butterfish. Historically, kelp forest ecosystems have demonstrated a high degree of resilience (27, 28), but recent evidence suggests that the capacity of kelp forests to recover from disturbance may be eroding (29, 30). From the holdfasts to the surface mats of kelp fronds, the array of habitats on the kelp itself may support This document is subject to copyright. These threats can be classified as either regional (within New Zealand and specifically the south-eastern South Island) and/ or global.

Underwater ‘crop circles’ that have been made in kelp forest around the Hauraki Gulf are part of a global experiment, and marine biologist Nick Shears hopes they will also show us how resilient – or not - the dominant kelp species around New Zealand might be in the face of climate change. This was achieved by comparing subtidal reef environments in southern New Zealand. In New Zealand, population densities up to 40 inds m −2 of the sea urchin Evechinus chloroticus create discrete coralline barrens patches within kelp forests (Choat and Schiel, 1982).

You can be assured our editors closely monitor every feedback sent and will take appropriate actions. The researchers noted that such an earthquake would very likely have laid bare some newly formed seafloor—ripe for occupation by kelp and other seafloor life. The earthquake was so severe that some parts of the seabed were raised above the water line. ), although numerous other genera such as Laminaria, Ecklonia, Lessonia, Alaria, and Eisenia are described.
