Meet your guide

Yoav Daniel Bar-Ness grew up between the coastal redwoods and the giant sequoia groves of California, studied forest ecology in the coastal rainforests near Seattle, and originally came to Tasmania to conduct the first on-ropes biodiversity surveys of the giant Eucalyptus treetops.

In the years since, he’s travelled 26,000km around India documenting trees as part of a Fulbright-Nehru Fellowship, conducted the first systematic measurements of the world’s broadest trees, climbed the world’s tallest flowering tree, mapped out Hiroshima’s atomic-bomb survivor trees, and clambered into the branches of a New Caledonian aracaurian pine. He has served as Field Editor and regular contributor to Asian Geographic Magazine, assisted international film documentaries, and founded Tasmanian Geographic. You can read his full CV here.
