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.

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!
