Date de diffusion: Août 29, 1966

This program deals with forest succession. Scientists have recently learned a great deal about the way in which new stands of forest grow - including the discovery that certain trees, like the jack pine, can only renew themselves in burnt over areas. D.H. Burton of the Department of Lands and Forests reports on studies of the impact of forest fires, logging, and the browsing of deer on the growth of a forest; also the controlled use of forest fires to reseed areas. R.O. Standfield of the Department of Lands and Forests explains the effects on forest wildlife, of controlled burning, and the use of chemical pesticides.
