Debs Martin, the Regional Field Officer for Forest and Bird, will give a brief talk on the rare plant and animal species as well as the history of this unique area. There will be time for exploration of the Boulder Bank, a meander along the marine reserve, a climb to a great look out over Tasman Bay or a swim. Koha will be used for tree planting to protect endangered birds.
The internationally-renowned Nelson Boulder Bank is a natural spit of boulders, formed of the debris of land slips from the Mackay Bluffs, swept southwards by sea currents over 10,000 years. The bank is 13km long, the last 8km forming a spit which separates Tasman Bay from Nelson Haven. Its width varies from 55 metres at high tide to 240 metres at low tide.
The shelter offered by the Boulder Bank was a major factor in choosing the site of Nelson. In 1848 a beacon was erected near the end of the bank and, in 1862, the cast iron lighthouse building that remains today. In 1906 a cut was made in the bank to allow easier passage to Nelson Harbour for shipping. 'The Cut' now separates Haulashore Island from the bank.
