JO CARPENTER, DOC 7 Fiordland, a place of wonder Those privileged enough to spend time in Fiordland find a place beyond superlatives – the landscape is simply stunning. From dramatic peaks, sheer rock faces drop into steep forested slopes whose cloak descends right to the water’s edge. INTRODUCING FIORDLAND Carved out by glaciers approximately 20,000 At the fiord entrances and along the outer years ago, the U-shaped fiords are characterised coast, conditions are very different, and much by near-vertical rock walls, which plunge several more dynamic.

Beneath the reflections of the fiords, fish communities. something unusual is happening. Fresh water soaking down through the carpeted forest floor absorbs tannins from decaying leaf matter, which stain it the colour of tea. On reaching the salt water, the less-dense fresh water floats on the surface forming a tea-stained layer that reduces the amount of light reaching the sea water below. Kelps, normally the basis of marine communities, do not grow well in the light-poor conditions, and are replaced by animals which normally inhabit greater, darker depths.

In 1995, when a suggestion was made that all fishing interests might get together and As vessels became larger and more powerful, and work on ways of looking after the fish stocks the use of floatplanes and helicopters became and fisheries of Fiordland, the response was more common, access improved markedly to overwhelmingly positive. all the fiords.
