Thinning by Poisioning in State Forests

C. R. Cruttwell



Thinning by poisoning has progressed over some 12,000 acres of exotic State forest since the practice was started in 1952 with the object of overtaking general arrears of treatment more quickly than has been possible by conventional methods. The practice has proved to have peculiar advantages in economy, in speed, in maintaining good access and stability, and in preserving the forest environment intact. These advantages appear to outweigh such risks to the health of the forest and safety of forest workers as are known to be incurred by the use of poisons.
