Recent research has suggest that so called sustainable logging techniques are not sustainable. The research was carried out in the Solomon Islands. The research found that the standard growing cycle of 30-40 years was not longer enough for trees to grow to the size desired by manufacturers. Therefore there was increased pressure on primary forests in order to gain the desired size of tree. Th research also found that as much as 50% of timber on the world market was illegally obtained.
