Young stand monitoring applied in the morice tsr r de jong csc winter workshop

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

∆ Leg and Practice

∆ TSR


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

Assess accuracy of inventory polys observed vs vri species composition

Assess Accuracy of Inventory PolysObserved vs. VRI Species Composition


Assess accuracy of si estimates observed vs provincial site prod tile

Assess Accuracy of SI EstimatesObserved vs. Provincial Site Prod Tile


Check on tsr assumptions tipsy msyts @ each sample point

Check on TSR AssumptionsTIPSY MSYTs @ each Sample Point


Localize msyts with ysm data

Localize MSYTs with YSM Data


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


Pine med au site index

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)
