Our Story

We love trees

giant trees, sprawling trees, monster trees, ancient trees

..and you will love them too

we will teach you how to listen to their stories

Exploring giant trees since 1999...

We've climbed and studied some of the world's tallest and largest flowering plants, conducted the first systematic measurements of the giant banyans, and explored significant trees internationally.

We've chased trees around the world..

From the redwood forests to the Himalayan slopes to the Australian rainforests to the heartland of China to the islands of Japan

Gum trees and bunya pines and figs in Australia • Redwoods and redcedars and sequoia and baldcypress in the USA • Spruce and fir in Canada • Giant banyans and baobabs and teaks and cedars in India • Kauri in New Zealand • Araucarians and strangler figs in New Caledonia • Dipterocarps in Borneo • Yakusugi giants in Japan • Ancient beech and oak in Europe • Metasequoia dawn redwoods in China • and more....

...as a scientist....

biodiversity surveys • branching structure • arboreal plants • insect life • forest dynamics, photomonitoring • leaf chemistry • vertebrate habitats •

... and as a documentarian.

• words • pixels • moving images •

...and conducting small-scale tourist expeditions to these spectacular forests

let's meet some of these amazing organisms and learn their lessons

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.

Now returned to Tasmania, he is on a mission to champion the superlative giant trees of the island as unique, world-class tourist attractions.
