Аннотация: In 1961 a record number of fires burned a record area and caused record losses. More than nine billion board feet of sawtimber and nearly nine million cords of smaller material were destroyed or damaged. A large proportion of the areas currently inaccessible for logging. Monetary losses from forest fires, the most difficult factors to assess were estimated at about 67 millions of dollars.

Аннотация: The forest fire season of 1963 was one of remarkable contrast. There were 7,670 fires reported in Canada. 7,557 in the provinces alone, totals exceeded only twice before, yet the average fire size in the provinces was a mere 58 acres, the lowest on record. At first glance these figures suggest a failture of fire prevention measures but a startling breakthrough in actual fire control. Of course, neither is correct. Improvement in fire control tends to be of a gradual nature while any sudden change usually can be traced to weather conditions.

Аннотация: The economics of forestry is sometimes considered to be rather special or distinctive discipline, but there is nothing novel or mysterious about the minimum-cost-plus-loss criterion for fire control, at least as far as the economic principles go. It is the same basic tool used for planning business and government endeavours and called variously marginal or benefit-cost analysis. The only difference, and it is that benefits received from the fire control are measured as reductions in losses rather than increases net revenues.
