One of the world''s first tree-top scientists, Meg Lowman is both a pioneer in her field - she invented one of the first treetop walkways - and a tireless advocate for the planet. In a voice as infectious in its enthusiasm as in its practical optimism, The Arbornaut chronicles her irresistible story.

From climbing solo hundreds of feet into Australia''s rainforests to measuring tree growth in the northeastern United States, from searching the redwoods of the Pacific coast for new life to studying leaf-eaters in Scotland''s Highlands, from a bioblitz in Malaysia to conservation planning in India to collaborating with priests in Ethiopia''s last forests, Lowman launches us into the life and work of a scientist and ecologist. She also offers hope, specific plans and recommendations for action; despite devastation across the world, we can still make an immediate and lasting impact against climate change.
