Coillte timber prices are based on the company’s own sales, while private sale prices are compiled by University College Dublin for the ITGA. Both sets of data are also made available to the Irish Farmers Journal. However, timber is sold by weight (t) rather than volume (m3) in Ireland, so a Sitka spruce commercial sale of 1,000m3 valued at €60/m3 is worth €67/t at a volume/weight conversion factor of 1.12.
