One landscape – two environmental histories

Two environmental histories converge in one landscape. In the foreground is the stunningly beautiful Lake Rotoroa, one of the two lakes in Nelson Lakes National Park, surrounded by wetland vegetation, transitioning into beech forest. In the background is a commercial pine plantation, with one slope scarred by clear-cutting. Nelson Lakes National Park, established in 1956, encompasses 102,000 hectares of the northern most Southern Alps. The lakes were formed by massive glaciers gouging out troughs in the mountainous headwaters of the Buller River during the last Ice Age. The vegetation is predominantly beech, with the red and silver species growing in lower, warmer sites and mountain beech at higher altitudes. The forests are habitat to South Island kaka (a large parrot), tomtits, robins and the tiny rifleman, New Zealand’s smallest bird.
