Forest Service scale and royalty invoices

  • GR-3180
  • Series
  • 1912-1975

The series consists of scale and royalty invoices created by the Forest Branch and its successor the Forest Service between 1912 and 1975. Depending upon the district, these records are either duplicate or triplicate copies. For some districts, invoices were to be paid at the Victoria Office, for others at the appropriate district office.

The records are arranged by forest district, and then numerically by account number. Records are available for the following forest districts: Vancouver, January 1913 to August 1976; Cariboo, September 1972 to November 1974, Nelson, April 1925 to February 1975, Williams Lake (also known as Cariboo), January 1913 to January 1932; Kamloops, February 1913 to March 1975; Vernon, February 1913 to March 1925; Cranbrook, October 1912 to March 1925; Prince Rupert, April 1913 to October 1974; and Prince George, March 1914 to June 1952. Account numbers are assigned chronologically within each forest district. However, when numbers became too large and unwieldy the account numbers were started over again at one.

The province collects royalties on all logs cut in the province. Over time the royalties owing have been calculated in different ways. Prior to 1894, each licensee or leasee provided a monthly written account to government of the number of trees cut on a particular property. This count was referred to as "stumpage" and fees were based on the numbers remitted. In 1894, the enactment of the Official Scaler's Act (SBC 1894, c. 35) resulted in the appointment of official scalers. Scalers followed scaling rules to measure the volume of logs cut and were usually employed by the provincial government. Scalers also determined the species and quality, or grade, of the logs. This information was then used to determine royalties owing to government.

Three scales were accepted for use in the province: British Columbia Board Foot Log Scale (BCFBM), Scribner's Decimal C and Doyle Log Rules. In 1915, only the British Columbia Board Foot Log Scale as accepted (Timber Royalty Act, SBC 1914, c. 76, s. 17). This scale estimated the amount of lumber that could be produced from a log, in board feet. The Forest Act (SBC, 1912 c. 17) provides the legal authority for the government's administration of scaling and requires that all logs be scaled before manufacture or shipment. The act is also used as the authority to determine which is the accepted scale. In 1946, the British Columbia Cubic Scale was introduced. This scale measured the volume of the log in cubic feet that might be ~suitable~ for the manufacture of lumber. In 1952, all measurements had to be done using the cubic scale.

A significant change occurred in 1965 when the BC Firmwood Scale Cubic Scale was adopted. This scale measured the net firmwood content of the log and was unrelated to its use for lumber. The purpose of this scale was to serve the government's requirements to assess fees and track the volume of harvests for statistical use and planning. By 1972, all other scales were discontinued. In 1978, a metric cubic scale replaced the imperial cubic scale. There are two primary methods of scaling used in the Province: piece scale and weight scale. Piece scale involves the measurement of each log harvested. This method is normally used in coastal areas where the logs are larger and not uniform in size. Weight scale is a sampling method where selected loads of logs over a period of time are piece scaled and this data is then used to estimate the volume of all other weighed loads. This method is used primarily in the interior of the Province and was introduced in 1963. It is used primarily for large volumes of smaller logs that are uniform in size. Other scaling methods may be used for small volumes of special products, for example, Christmas trees or fence posts.

Northern Interior Forest Region silviculture records

  • GR-3916
  • Series
  • 1973-2009

This series consists of silviculture experiments and audit records from the Northern Interior Forest Region, 1973-2009. The Northern Interior Forest Region was created with the amalgamation of the Prince George Forest Region and Prince Rupert Forest Region in 2003. The region has included a variety of different forest districts. Records may regard the following Forest Districts: Cassiar, Dawson Creek, Fort Nelson, Fort St. John, Fort St. James, Kalum, Kispiox, Mackenzie, Morice, Prince George, Quesnel, Robson Valley, and Vanderhoof. Note that the names and boundaries of districts and regions varied over the years.

The Ministry of Forests defines silviculture as “the art and science of controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society on a sustainable basis.”

Silviculture (SX) experiment files regard trials completed under the jurisdiction of the silviculture program. Includes records detailing all silviculture trials conducted, working plans, results, evaluations, reports, models, copies of articles, maps, data, photos, slides, field notes and video tapes.

Silviculture audit and assessment files regard the audits and assessments made by the Ministry to ensure basic silviculture is carried out in accordance with regulations and approved silviculture prescriptions detailed in the Forest Practices Code of British Columbia Act. Audits evaluate whether or not there has been compliance with the regulations, the silviculture prescriptions are suitable, and there is acceptable progress towards achievement of silviculture objectives in the approved silviculture prescription. Silviculture prescription audits are carried out on areas under both major licences and areas under the Small Business Forest Enterprise Program (SBFEP) with approved silviculture prescriptions. Major licence audits relate to the operations of a specific company identified in the file title. SBFEP audits will include multiple operations in a particular district; these are identified in the files by timber sale licence (or other tenure type) number. Records can include correspondence, inspection forms, reports, and compliance reports for soil conservation, regeneration, free growing obligations, slides, photos and video tapes.

The series also includes some additional records related to silviculture such as openings, stock surveys and planting information. Related procedures may be included in this series or GR-3918.

The ministries responsible for the Forest and Range Districts, and the years that they were responsible, are:
