How much CO2 will a Wollemi Pine sequester?
This is a difficult question to give an exact answer to due to the fact that no 2 Wollemi Pines seem to grow in the same manner and the first tree was only planted in the UK in 2005. The typical form of Wollemi Pine in the wild is a tall long-lived tree that has a coppicing habit. Mature trees are usually multi-trunked with up to 100 stems of various sizes. The oldest tree in the wild is 1000 years old and has 100 trunks due to the ability of the tree to coppice. The Bill Tree; the tallest tree in the wild is 40 metres tall but this is because it is growing in a canyon. We expect Wollemi Pines in the UK to grow to an ultimate height of about 20 metres in good growing conditions. To enable us to calculate the quantity of CO2 sequestered we must look to a close relation of the Wollemi Pine; the Hoop Pine (Araucaria cunninghamii) which has a density of 575Kg/cubic metre at 12% moisture content. The weight of a tree normally shrinks by about 10% in drying so it would be expected that the H
