Kauri
Swam Kauri or ‘ancient Kauri’ are prehistoric Kauri trees (Agathis Australis) buried and preserved in peat up to 50.000 years ago in New Zealand’s North Island. Buried under a peat swamp by an unexplained act of nature at the end of the last Ice Age, the trees have survived the centuries underground, sealed in a chemically balance environment that has preserved the timber in perfect conditions. The tree is the national tree of New Zealand and some had a height of nearly 200 feet (60 meter). Kauri trees are highly protected and even for excavation from the swamps a special license is needed. The so called C-14 method is used as best scientific proof of the ancienity of a Kauri tree. Kauri products typically come with an age certificate.
