Most who make the voyage across the Foveaux Strait to Stewart Island do so to see the native birds on the secluded island. However, the trees that are found here are an added reward for those who venture across the dangerous strait. Stewart is an oddity amongst New Zealand’s three largest islands. On the North and South Islands the beech tree dominates most of the forests, but on Stewart there are no beech trees to be found. It is believed that all the native species of trees found on Stewart Island are the result of birds having brought over their seeds from the South Island. Since beech tree seeds rely on the wind to disperse there seeds, not the birds, the pervasive species never made it to this island.
