Young Stand Monitoring

applied in the

Morice TSR

R. de Jong

CSC Winter Workshop

27 February 2014

assessment of mid rotation stands
Assessment of Mid-rotation Stands

Stand Development Monitoring

(SDM)

Young Stand Monitoring

(YSM)

To assess TRENDS of young stands relative to TSR assumptions and adjust (FAIB)

Management Unit assessment – permanent sample plots established on a grid over the target population

  • To assess Timber Objective of FRPA (FREP)
    • To change Legislation if required
    • To change PRACTICE if required
  • Stand Level assessment – 10 plots per polygon, summarized per TSA

morice ysm program
MoriceYSM Program
  • Established 2012
  • 50 * 0.04ha plots
  • Grid Based
  • Unbiased estimate of 15 – 50 year old target population
objectives
Objectives
  • Describe Young Stand Characteristics
  • Assess Accuracy of Inventory Polygons
  • Assess Accuracy of Site Index Estimates
  • Check on TSR Assumptions
  • Localize MSYTs using YSM data
describe stand characteristics structure

localize msyts with ysm data site index adjustment
Localize MSYTs with YSM DataSite Index Adjustment
  • TSR-based SI underestimated compared to ground-based site index.
  • Action: apply site index adjustment by species
localize msyts with ysm data species composition
Localize MSYTs with YSM DataSpecies Composition
  • YSM ground species mix vs. TSR assumptions
  • Action: Apply YSM species mix by AU
localize msyts with ysm data forest health impact
Localize MSYTs with YSM DataForest Health Impact
  • Worst-case FH scenario assumes all stem rust affected Pine will die at rotation.
  • Action: Apply incremental OAF1 in Pine dominated regimes
summary
Summary
  • YSM to describe young stand population
  • YSM as a check on TSR assumptions, both current and future stands
  • YSM to generate localized MSYTs
  • YSM to support alternative modeling scenarios with measured data (forest health)
  • Future YSM data to include change (growth / mortality)
