Another Side of the Forest

Developments in the Canadian forestry industry during the 1970s are shown being carried out both as lab experiments and in the field to protect and conserve the country's vast forests. These include turning a Newfoundland bog into woodland, fostering British Columbia seedlings that withstand mechanical planting, inoculating Ontario elms against the bark beetle, devising ways of controlling fire, and more.
