Above the Treeline

Book excerpt: New Zealand's alpine environment is challenging, not only for the humans who explore it but for the plants and animals that inhabit it. The extremes of temperature, short summers and high rates of erosion make for an uncertain environment, and the flora and fauna have evolved and adapted to it in interesting ways. Above the Treeline: A nature guide to the New Zealand mountains is a guide to the natural history of these fascinating ecosystems. It is the first book to be published that brings together the range of flora and fauna that inhabit the alpine environment. As well as our unique alpine plants, which constitute the majority of the book, this guide includes birds; frogs and lizards; butterflies, moths, grasshoppers, beetles and other invertebrates; and mosses and lichens. An informative introduction is followed by descriptions of more than 850 species, illustrated by approximately 1000 colour photographs.
