FRPA Silvicultural Tests2
2: MOFR, 2006. An overview reference for the evaluation of stocking standards under FRPA.
Test 1: Initial High level
Coarse filter evaluation to determine if there are any
obvious omissions or issues impeding FSP approval –
does it cover the anticipated situations and
circumstances (e.g., forest types, ecosystems,
silviculture systems) to be encountered; can the
proposed standards be measured to a reasonable
level of precision and accuracy
Test 2: Ecological Suitability
Species are appropriate for the given BEC
subzone/variant and site series and for the
silvicultural systems applied
Test 3: Forest Health
The regeneration date and stocking standards will
result in the area being stocked with ecologically
suitable tree species that address immediate and
long-term forest health factors; includes landscape
level concerns (e.g., over-deployment of one
species)
Test 4: Economically valuable supply of timber
Species are valuable with respect to future options
for products and values; maintenance or
enhancement of a mix of species is considered a
reasonable strategy; usually includes restrictions on
acceptance of lower value species that can
proliferate naturally (at stand or landscape scales)
Test 5: Consistency with the timber supply review
The “set” of standards are linked to local assumptions
for the sustainability of timber flows over time; does
not preclude new standards that address emerging
objectives, knowledge, science, or management
challenges; standards could be rejected if they put
projected timber flows at risk

Primary, Secondary & Tertiary
Primary species
Primary tree species are ecologically acceptable and have
a high rating for silvicultural feasibility, reliability, and
productivity under the average conditions for a site series.
Primary species can be managed as a major component in
a stand if the restrictions have been adequately addressed.
Note: Primary species are not by default the preferred
species. Species from any of the three categories can be
chosen as preferred, if the species meets the identified
management objectives and if restrictions can be dealt
with through treatments.
Secondary species
Secondary species are ecologically acceptable, but rank
lower than primary species for one or more of silvicultural
feasibility, reliability, or productivity. Depending on the
nature and extent of these limitations, secondary species
can be managed as either a major or a minor component
in a stand.
Tertiary species
Tertiary species are ecologically acceptable, but rank lower
than primary or secondary species for one or more of
silvicultural feasibility, reliability, or productivity.
Depending on the nature of their limitations, on local
conditions, and on management objectives, tertiary
species are normally suitable only as a minor component
within a stand. For example, tertiary species can be used
as a minor component of all stands within an area.
Evaluation Criteria
Preferred and Acceptable
Maximum sustainable productivity
To satisfy the maximum sustainable
productivity criterion, the relative productivity
for each tree species, or combination of tree
species, was evaluated to determine which
were best suited to each ecosystem unit.
Preferred species
Preferred species are ecologically suited
to the site. Management activities are
primarily aimed at establishing these
species. The characteristics of these
species are consistent with the desired
timber and non-timber objectives for
the site.
Crop reliability
To satisfy the crop reliability criterion, the
relative susceptibility to natural hazards was
evaluated for each tree species, to determine
which species provide the most reliable
choices for a future crop on a given site series.
Established stands should be both resilient and
resistant to all anticipated hazards, so that
they will survive until harvest.
Silvicultural feasibility
To satisfy the criterion of silvicultural
feasibility, ecologically viable tree species were
evaluated, based on accumulated silvicultural
experience, to determine whether they were
able to produce sawlogs in a cost-effective
manner on each site series within an
acceptable rotation length.
Acceptable species
Acceptable species are ecologically
suited to the site, but management
activities are not aimed at establishing
them. The reasons for including a
species labelled only as acceptable may
be a higher-than-acceptable site
limitation, such as pest risk, or a lower
productivity than the preferred species.
Special restrictions or limitations may
apply to the use of these species.
