Growth Projections

GROWTH PROJECTION PAULOWNIA COT2 IN SPAIN

The data below shows a conservative growth projection of paulownia timber plantations in Spain obtained by measuring a number of plantations across different regions within Spain.

The table is focused on usable good quality timber which is estimated to be at a maximum height of 6 meters. However, due to the 0.8 – 0.9 Smallian factor of Paulownia COT2 we aim to increase the usable quality paulownia timber of our plantations from 6 up to 7+ meters.
