![]() Where do they occur?Ĭoastal rock stacks are widespread in New Zealand wherever elevated topography abuts the coast, and absent only from long, sandy or shingly stretches like the central Bay of Plenty and South Canterbury Bight. Native plants, however, tend to dominate. Weed invasion can occur, however, promoted by instability of cliffs and seed transport by wind and birds. Most coastal rock stacks are protected by their inaccessibility to humans. Coastal rock stacks may support breeding sites for threatened seabirds, such as the light-mantled sooty albatross ( Phoebetria palpebrata ), Salvin’s albatross ( Thalassarche salvini ) and the Chatham albatross ( Thalassarche eremita ), and less threatened seabirds such as the common diving petrel ( Pelecanoides urinatrix ), grey-faced petrel ( Pterodroma macroptera ), red-billed gull ( Larus novaehollandiae ), white-fronted tern ( Sterna striata ), and the spotted shag ( Stictocarbo punctatus ). Threatened fauna include the Mokohinau skink ( Cyclodina mokohinau ) and a stag beetle ( Geodorcus ithaginis ).

In big storms, however, waves may crest over the tops. Their summits are well above the high tide line and above the storm surge line (over 10m in height). Some are always surrounded by water, others are surrounded by sand at low tide. The bases of stacks occur below the high tide line. ![]() Coastal rock stack, western Southland (Susan Wiser)Ī coastal rock stack is an isolated pinnacle of rock off the coast, generally with steep to vertical sides (Priestly 1990).
