This short documentary looks at how modern technology affects the forestry industry and the role of the forester in ensuring the sustainability of this great natural resource. It was in the '60s that people started to realize that the forests did not provide an endless supply of wood, and thanks to recent developments in the science of forestry, people are learning how to manage the resources more effectively.
Filmed in several of Canada's national parks (including Banff and Wood Buffalo), this feature documentary looks at forest fires versus fire suppression. Sometimes forest fires are essential for plant renewal, healthy growth, soil enrichment and new environments for wildlife.
This documentary looks at developments in the Canadian forestry industry from the 1970s. 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... these are some of the experiments shown being carried out in laboratories and in the field to protect and conserve the country's vast forests.
This short film serves as a cautionary tale to farmers who recklessly cut down trees on their land. When prairie farmers engaged in this practice to facilitate plowing, they discovered that the trees had served as windbreaks protecting top soil from erosion. The Dominion Department of Agriculture's experimental station at Indian Head, Saskatchewan, cultivated acres of young trees for distribution to farmers.
This 1950s' film looks at the measures to preserve water flow from the Rocky Mountains. With the steady falling of the water table, the exploitation of timber stands and the recession of glaciers, water conservation was an urgent concern of the Alberta and federal governments.
This short documentary demonstrates how to efficiently manage a woodlot in order to maximize yearly income. Joe Kelly, a farmer who sold his trees to be cut down wholesale, illustrates the danger of short-sighted planning. Given a second chance on his father's farm, Joe learns to practise selective cutting, which allows for a sustainable woodlot and a steady income. The film also offers information on which trees to cut and how to market the wood.
This 1950 documentary examines the penalties of forest destruction: fire, flood, wasted resources and barren lands. The film describes measures to preserve Canada's prime source of national wealth. Scenes of the wilderness created by stripping land of protective trees show the need to halt careless exploitation. Contrasting the slow process of re-seeding with the swift, modern methods of felling trees, the film urges planned cutting to ensure a protected yearly crop.
