Effect of Prescribed Burning in a Forest on Wood Characteristics of Jarrah

Wood specimens have been examined which were collected from three positions along the merchantable bole of jarrah (Eucalyptus marginata Sm.) trees growing in Western Australia. These trees had been subjected to a series of two experimental fires at either of two intensities in either spring or autumn. The more intense fire caused crown and trunk damage and resulted in kino vein formation. If such burning took place in autumn, loss of radial growth resulted. The less intense fire treatment did not result in external damage. Minor disturbances to the density profiles in the first year after the fire were the only observed effects on characteristics of the wood.
