The marine reserve protects all marine life within its boundaries, benefiting not just fish and shellfish, but also animals like seals, penguins and other seabirds that live on the land but feed in the sea. Human activity has put considerable pressure on the Abel Tasman marine environment, and caused a marked fall in fish numbers. In 1990, studies by the Department of Conservation confirmed the coast's uniqueness and paucity of fish life. When marine reserve options were released for public discussion, strong support for protection emerged. The area finally chosen was the most widely supported one.
Research is undertaken to monitor changes to the marine ecosystem now that fishing has stopped.
Please be careful around any scientific equipment on the sea floor. The estuaries link the marine reserve to the national park, which in turn buffers the reserve against potentially damaging land practices. What To See And Do Most popular activities along the coastline are enhanced or unaffected by the marine reserve. Because fishing is not allowed, fish life in the reserve may increase, possibly improving fishing outside its boundaries. The best way to get close to the reserve and its inhabitants is to get into the water.
