After felling, timber will lose moisture to align itself with the atmospheric conditions. Moisture content should be lower than 20% to stop fungal attack. Seasoning is the name of the process where moisture content is reduced to the appropriate level for proposed use.
Shrinkage will occurs as a result of the moisture loss - typical 3-4% across the grain.
