Public sustained yield unit policy files
- GR-3700
- Series
- 1955-1985
The series consists of policy files relating to public sustained yield units. These records were created between 1955 and 1985 by the Ministry of Forests and its predecessors. The records were created by the ministry’s central office in Victoria and relate to all areas of the province. These files were used for planning in public sustained yield unit areas.
Public sustained yield units (PSYU) were used by the ministry between 1948 and 1978. They were the method by which the ministry regulated harvest rates. PSYUs were an outgrowth of the 1945 Royal Commission on the Forest Resources of British Columbia. This commission recommended that the ministry should establish forest management units to ensure the long term sustained yield of timber.
The ministry established 88 public sustained yield units in the province and these are reflected in the records of this series. In 1978, the ministry replaced the system of public sustained yield units with timber supply areas. The 88 PSYU’s were reduced to 33 timber supply areas.
Records contain correspondence, maps and reports. The correspondence is with ministry staff, other ministries and third parties including businesses and individuals. The majority of the documents relate to forest use but there are also records that relate to other land use information including mining, recreation, parks, and environment. The reports include computer printouts and written reports. The computer printouts contain information about forestry yield.
Files are arranged alphabetically. There is a file for each of the PSYUs in the province. Each file has also been assigned a classification number that begins with the numbers 700-6-1. This classification number was first assigned to the records ca. 1979. Documents in each file that were created prior to 1979 have been assigned a “0” number. The “0” numbers are 7 digit numbers that are part of a filing system that was created by the Dept. of Lands which was a predecessor of Forests.
