Timber Supply Review and

Species Management

By: Paul Barolet, R.P.F., Stewardship Officer

GREAT CSC THEME !

*Speciesism = prejudice or discrimination based on species, and does it matter to the AAC?

• Let’s examine some situations in less than 1 minute per slide.

• Is speciesism already a reality in current TSR‘s?

This 2006 report cited a number of concerns and made recommendations related to monitoring practices for timber supply

Forest Cover Data Integrity and Timber Supply

• Regarding forest cover attributes applied in TSR forecasts, please remember that;

DATA IN = AAC FORECAST OUTor

GARBAGE IN = GARBAGE OUT

• Think about Baskerville’s comments and that TSR forecasts should mimic the on ground reality (current practice) in the forest both in terms of yield curves and harvest flows.

• In summary TSR’s are to reflect current practices in their modelling assumptions (see Forest Act section 8).

Forest Cover Reporting

1. Coast Regional Implementation Team; messaging & consensus on stocking standards and forest cover reporting

2. FPPR section 863. RESULTS Information Submission Specifications Manual 4. SUBMITTING FOREST COVER TO RESULTS FOR OPENINGS

WITH TREED RETENTION5. Silviculture Survey Procedures Manual - Regen Delay, Stocking

and Free Growing Surveys - plus Alternative Survey Methodologies

6. Forest Management Leadership Team Forest Cover direction letter

This includes standing waste!

Previously Harvested StandsMid-Coast TSR 3 Experience

• a net area of 7120 hectares. Most of these stands were apparently excluded because of low net value and inventory attributes....About 87 percent of the stands were hemlock or balsam leading,....

• I estimate that about 50 percent of previously harvested stands that were excluded as inoperable will contribute to future timber supply in the TSA.

• This resulted in a loss of 3560 ha or 2.2% of THLB.

Inventory and THLB does it matter?

Silviculture does it matter to the AAC?

• Timber supply requires unbiased and accurate forest cover reporting regardless of the source.

• Timber supply areas increasingly reveal both economic and logistical challenges associated with less diverse stands and high logging costs which is considered in timber supply.

• When weighing your economic decision to rely on natural ingress outcomes consider how this affects the THLB based on previous TSR’s and managed stand yield curves and site index adjustment.

• THLB reductions could be offset with inventory attributes of residual basal area to contribute to future timber supply.

Silviculture does it matter to the AAC?

• Timber supply analysts should revisit even aged yield curves assumptions (base case) relative to growing conditions under current practice.

• Has the scale of resolution for analysis units become too generalized?

• Professionals are responsible for;– surveying and accurately reporting forest cover of stand

conditions when >5m2/ha is retained– meeting all legal policies and professional expectations

• Yes, silviculture matters to the AAC!
