Numerous investigations into the effects of different types of fire on blackthorn were conducted. The basal stems of blackthorn were burned with a gas flame at soil level and 12 inches above soil level for periods of 1, 3 and 6 minutes respectively. An illustration of a ?flame girdling? apparatus which was especially constructed for these investigations and a description of its operation, is presented. A total root kill of blackthorn was obtained by burning the lower basal stems of the plant for periods of 3 and 6 minutes respectively. All other burn treatments resulted in the development of coppice shoots. A fire?mechanical method for eradicating blackthorn is suggested.
