This policy provides standards for the measurement and estimation of
Crown timber that will be harvested.
Crown timber on each cutting authority will be inspected, cruised and
computed according to the standards and procedures in this policy.
The timber cruise will provide the estimate of volume, species
composition, quality of timber and other data required to determine
Cruising is the measurement and estimation of volumes of
standing and down Crown timber on a given parcel of land.
Check cruising is the systematic check of the quality of the
design and fieldwork of a cruise to determine whether it meets ministry
standards. Where a cruise is selected for checking, a minimum of 10
percent of the fieldwork will be checked. The provincial Cruising
Manual lists the required fieldwork and the acceptable measurement
Cutting Authority means a cutting permit or an application for a
cutting permit, or a timber sale licence, or a timber sale licence that
has been advertised.
Cruise-based licences are cutting authorities where the licensee
is billed stumpage on the basis of cruised volume.
Check Cruising Standard
The checking standards for each district are as follows:
- 100 percent of cruise-based licences.
- 50 percent of scale-based cutting authorities. Cruisers,
agencies, or licensees that do not have an established record of
accurate cruising will be checked more intensively based on risk
- The checking standards for low value sales and low risk cruising may
be modified by the Regional Manager but shall not be lower than:
- 50 percent for cruise-based cutting authorities
- 25 percent for scale-based cutting authorities.
Cruise Package Review
A check of each timber cruise will be made to ensure that the cruise
plan, the fieldwork and the compilation are completed to ministry
standards. Checking applies to licensee's cruises and cruises
carried out by or on behalf of the Ministry.
Cruise Compilation Check
Each region will conduct at least four compilation technical reviews
annually, including a systematic check of the cruise compilation from
tally cards to final reports and a recompilation. Revenue Branch
will conduct a check of all cruise compilation programs when they have
been changed or modified.
Recording and Reporting
Each district must maintain a program of check cruising and a check
cruising ledger. Regions will monitor each district and report
annually to the Regional Manager on the level of check cruising activity
and the quality of cruising.
Adverse Weather Conditions
Cruising should not be done if adverse weather conditions affect the
standard of tree measurement vital to the stumpage rate determination.
Reconnaissance surveys using cruising techniques will be planned and
carried out when required in order to evaluate the degree of damage to
forest stands by wind, fire or insects.
Cruising procedures and computerized output design for appraisals are
the responsibility of Revenue Branch.
Modification of taper equations and their constants, loss factor tables
and computerized rules for interpreting the standard log grades require
the approval of Revenue Branch.
These procedures apply to the cruising policy. Other procedures
are prescribed in the Ministry of Forests Cruising Manual and in
the regional cruising guidelines.

- provides technical and interpretative liaison with Regional Cruising
Co-ordinators and industry; and
- conducts a technical review of one region per year to ensure the

- ensures that the cruising policy, procedures and standards are
implemented and adhered to throughout the region; and
- ensures that sufficient cruising capability and competency is

Regional Revenue Manager

Regional Cruising Co-ordinator
The Regional Cruising Co-ordinator interprets and administers the
policies and procedures established for regional operations by:
- ensuring that standards are adhered to uniformly and consistently,
without impeding the consideration of site specific and local situations
which affect timber pricing;
- monitoring 3 districts every year to ensure that all timber
offered for sale or under application for harvesting is cruised to a
standard that meets the requirements of the appraisal, billing where
applicable, and reports the level of performance to the Regional Manager
with recommendations. The monitoring is to include a random
recheck of a cruise that was check cruised;
- conducting or arranging for at least four compilation checks
- training selected ministry employees in the district to ensure they
are competent to perform cruises, check cruises and compilations; and
- ensuring that all licensees, consultants and technical schools
within the region are conversant with the cruising policies and
procedures of the Ministry.
- maintains sufficient cruising capability and competency;
- maintains a program of check cruising, a check cruising ledger and
annually reports to the Regional Manager on the level of check cruising
activity and on the number of acceptable and unacceptable cruises of
- ensures that cruising and check cruising activities are carried out
in a timely manner and in accordance within ministry policy and
- estimates and budgets for required funds to retain outside services
if required to undertake cruising on behalf of the Ministry.
