  1. Baseline DevelopmentWhat’s it all mean anyway? Alanya Smith & Nancy Densmore

  2. What are our Options? • one – to – one • Pre-harvest and post-harvest sampling of same block • one – to – many • Post-harvest sampling placed in the spectrum of available data from the same ecosystem SBS dw

  3. “Premium” one-to-one baseline • Pre-harvest data from the same stands – using the same methodology • cooperation with licensees to find unharvested but planned blocks • 2 sampling sessions on each block (double the cost?) We can dream…

  4. “Premium” one-to-many baseline • Pre-harvest data from blocks that fit the population description – same sampling methodology • 180 harvested zone/subzone X 30 blocks X $3,000 = $16,200,000 $ $ So, Peter….. $ We can dream…

  5. Cheaper one-to-one:cruise data same block • BCTS cruise data • good for standing trees (no record of CWD on block) • difficult to track down BCTS electronic cruise plot data. …An odyssey soon to be made into a full length feature drama….

  6. Nancy and Alanya’s Data Search Odyssey • BCTS Official notices system (2005) • First approach made to CanFor • Contractor hired • BCTS Official notices system (2006) • GENUS

  7. Cheaper one-to-many lumped cruise data Success at last… • Use available electronic cruise plot data from the BCTS ONS • 2005 final report – example comparison of SBS sampled cutblocks to 51 BCTS cruise blocks.

  8. Existing Research • Available research data - but its not necessarily from the same population, collected the same way or with same quality rigour (FREP Report 1: Baseline Datasets for Evaluating Wildlife Tree Patches, November 2004) • Deadtree database for CWD

  9. Even distribution of large tree retention

  10. Skewed distribution – emphasis on retaining large trees

  11. 2005 Report: Abundance of large trees found in sampled cutblocks compared to the baseline (SBS)

  12. Summary • Approx 270 plots of baseline • Testing required - Alyson McHugh testing the one-to-one “premium” in the Arrow district • Fire & MPB
