Wood Species - Weight at various Moisture Contents

Weight of green and air-dry fuel wood

The amount of bounded water in wood is determined by the relative humidity (RH) of the surrounding atmosphere. The amount of water in wood changes slowly as the relative humidity of the surrounding air changes.
