Stand Management Prescription Guidebook

Table of contents

C-2. Current stand description

The current stand description provides detail on the structure, species mix and percentage, age, height, site productivity (site index), stand density, number of well-spaced stems/ha, and basal area. This section can be completed by transferring the appropriate information from free growing or pre-stand-tending surveys. For even-aged stands the first line is for inventory information, the second line is for silviculture information. For uneven-aged stands, record the information by layers 1 through 4. Use the Guide to Completing FS 708 Forms for further assistance.

Strata/or treatment area

Enter the alpha or numeric value corresponding to the area on the map. You may wish to separate out treatment areas or combine them (if they are the same). In either case the stand types should be similar enough to require the same treatment.

* Layer

Enter the kind of layer ( ) - inventory, (S) - silviculture, (V) - veteran, (1) - layer one trees equal to or greater than 12.5 cm dbh, (2) - layer two trees between 7.5 and 12.4 cm dbh, (3) - layer three trees between 1.3 m tall and 7.4 cm dbh, and (4) - layer four trees beneath 1.3 m tall.

Rank

Rank each layer of a multi-layer stand in the order of their harvest importance starting with `1' for the most important.

Species composition/percent

Enter the percentage species composition (nearest one percent) to a maximum of five species. The total species composition should add up to 100 percent.

* Age

Enter the age on-site (to the closest year) of the leading species (codominants and dominants).

* Height

Enter the height in metres to the nearest tenth of a metre.

Reference year

Enter the year the survey information was collected.

* Site index

Enter the site index for the stand to the nearest tenth of a metre (in line one).

* Density

Enter the total number of stems per hectare.

* Well-spaced

Enter the total acceptable well-spaced stems per hectare.

C-3. Forest health and protection

Forest health assessment

Insects, disease, wildlife and abiotic factors can have a significant impact on forest productivity and may limit the ability to meet management objectives.

* The SMP must for each standards unit, specify the occurrence of forest health factors that are currently causing damage and the strategies, if any, to mitigate the impacts of identified factors. All anticipated future forest health risks should be identified when developing plans and prescriptions.

Forest health management objectives should be documented in this section.

* Where there are pests currently, the prescription must identify the pest and estimate the percent or magnitude of infection, by standards unit if necessary.

Where the potential of damage occurring later in the rotation is identified, the type of pest and an assessment of the risk to the stand should be provided.

Any actions proposed to address pest concerns must be specified in the prescription.

This section should include treatment windows where treatment during a specific time of the year is critical. For example, sanitation of stem rusts during a time of the year when the spores are visible.

Filling out section C-3 of the SMP template

SU

Record standards unit

*Agent code

Record agent code for specific pest code as per ISIS codes (or FS 747)

* Agent name

Record commonly used name

* Host species

Record host species

* Total trees affected

Record percent of total trees affected

* Total conifers affected

Record percent of total conifers affected

* Host trees affected

Record percent of total host trees affected

Describe the management objectives for the agent (e.g., minimize the spread of armillaria).

Protection

Increased fire hazards such as concentrations of woody debris or slash resulting from stand management practices should be reduced to an acceptable level. Abating the hazard should not be at the expense of site productivity.

Hazard abatement must be consistent with higher level plans and should be conducted in accordance with the Fire Management Guidebook.

The SMP should make an assessment of the fire hazard and fuel loading expected after the silviculture activity and, where fire hazard abatement is anticipated, specify the actions to be undertaken and the expected time frame for completion of the work.

The fire site sensitivity rating will influence hazard abatement options.
