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 concerns and made recommendations related to monitoring practices for timber supply

Inventory Discrimination in the Mid-Coast TSA

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 in the forest both in terms of yield curves and harvest flows.

Forest Cover Reporting

• Coast Regional Implementation Team Consensus • FPPR section 86• RESULTS RISS Manual • RESULTS Treed Retention Manual • Silviculture Survey Procedures Manual • Forest Management Leadership Team• ALL FIVE DOCUMENTS HAVE ONE ELEMENT IN

COMMON, SURVEY AND REPORT BASAL AREA WHEN >5 M2/HA IS RETAINED

This includes standing waste!

Previously Harvested StandsMid-Coast TSR 3 or Speciesisms?

• 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?

Speciesisms does it matter to the AAC?

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

• Timber supply areas increasingly reveal both economic and logistical challenges associated with less diverse/low net value 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.

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

Speciesisms does it matter to the AAC?

• Timber supply analysts should revisit yield curve assumptions (base case) for EBM areas relative to growing conditions and,…..

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

• Silviculture surveyors as 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, speciesisms matters to the AAC!
