Post-inoculation monitoring (3–24 months)

1. Monitoring Objectives

After inoculation (fungal, chemical, mechanical, or dual-action), monitoring is essential to:

  • Assess resin formation around inoculation sites
  • Detect tree stress or infection beyond intended inoculation
  • Plan harvesting or re-treatment if necessary
  • Ensure overall tree health for future resin cycles

2. Monitoring Timeline & Parameters

A. 3–6 Months Post-Inoculation

Purpose: Early response detection

Observations:

  • Wound healing / callus formation
  • Discoloration around inoculation site (wood darkening)
  • Moisture retention at the wound
  • Signs of contamination: unwanted fungi, mold, or decay

Actions:

  • Remove or re-seal any exposed inoculant if contamination occurs
  • Adjust soil moisture and nutrition to reduce stress

B. 6–12 Months Post-Inoculation

Purpose: Resin initiation monitoring

Observations:

  • Dark streaks or patches in xylem around inoculation site
  • Fragrance detection: light aromatic smell indicates early resin formation
  • Tree vigor: check leaf color, new shoots, and growth rate

Actions:

  • Continue regular irrigation and organic fertilization
  • Document size and spread of resinous wood
  • Optionally, non-destructive sampling (small wood chips) for quality check

C. 12–18 Months Post-Inoculation

Purpose: Active resin accumulation

Observations:

  • Resin-rich wood darkening more pronounced
  • Fragrance intensity increases
  • Distribution: check if resin is forming uniformly around inoculation sites
  • Tree health: check for signs of over-stressing or dieback

Actions:

  • Continue tree care (fertilization, irrigation, pest control)
  • Consider additional induction in underperforming areas (if dual-action inoculant allows)

D. 18–24 Months Post-Inoculation

Purpose: Resin maturity & harvest readiness

Observations:

  • Well-formed resin blocks visible around wound
  • Fragrance profile approaching market quality
  • Signs of decay or over-infection (may require early harvest or tree pruning)

Actions:

  • Evaluate harvestable resin quantity and quality
  • Plan sustainable re-inoculation cycles
  • Record data for ROI and yield modeling

3. Monitoring Techniques

TechniquePurpose
Visual inspectionWound condition, discoloration, resin accumulation
Palpation / scrapingDetect hardened resin, early aromatic detection
Small core samplingNon-destructive analysis of resin content
Photography / mappingTrack progression over time
Fragrance assessmentEvaluate resin maturity and quality
Tree health checkLeaf color, canopy density, pest/disease presence

4. Record-Keeping

  • Maintain a tree-by-tree monitoring log:
    • Date of inoculation
    • Type of inoculant used
    • Wound location & depth
    • Observations at each monitoring interval
    • Resin formation progress (color, spread, fragrance)
    • Tree health indicators
  • Use this data to:
    • Determine best harvest timing
    • Optimize future inoculation protocols
    • Model yield and ROI

5. Best Practices

  1. Monitor every 3 months during the first year, then every 6 months thereafter.
  2. Avoid excessive handling that could damage resin or introduce contamination.
  3. Combine visual, olfactory, and small sample assessments for accurate resin evaluation.
  4. Ensure tree recovery with irrigation, organic fertilizers, and pest control throughout the monitoring period.
  5. Document all findings for training, research, or plantation management.
