What To Monitor

Forest resources can be monitored using various techniques, ranging from simple assessments to more complex statistical sampling of ecosystem attributes. Which attributes you measure, as well as the frequency of your monitoring, depends on the kind of forest you have and your management objectives. The sections below identify various monitoring protocols you can use on your forest, including links to field forms.

Forest Inventory

  • Purpose: Determine baseline stand and timber information, comply with FSC monitoring requirements (Indicator 8.2).
  • Data: Quantitative – statistical sample and permanent plots
  • Variables:
    • Tree species, diameter, defect, height, and age
    • Sapling species and diameter
    • Shrub species and percent cover
    • Number of snags
  • Forms:

Forest Stand

  • Purpose: Track important ecological and physical attributes through time.
  • Data: Qualitative – walk transects through the forest
  • Variables:
    • Forest health and ecological hotspots
    • Wildlife
    • Trees and shrubs
  • Form: Stand Assessment

Roads

  • Purpose: Detect and track road deterioration, maintenance needs, or negative environmental impacts.
  • Data: Qualitative – traverse road segments
  • Variables:
    • Road issues and severity
    • Maintenance needs
    • Appropriateness of culvert size compared to stream
    • Passability of culverts on fish bearing streams
  • Form: Roads

Streams and Wetlands

  • Purpose: Track general stream conditions and detect any detrimental disturbance impacts.
  • Data: Qualitative – walk stream segments and around wetlands
  • Variables:
    • Channel and wetland characteristics
    • Water quality
    • Vegetation
    • Stream organisms
    • Wetland wildlife
    • Large woody debris
  • Forms:

Biodiversity

Carbon Sequestration

  • Purpose:
    • Quantify forest carbon storage
    • Enter voluntary and/or regulatory carbon offset markets
  • Data: Quantitative – inventory with permanent plots, and carbon calculator
  • Variables:
    • Species, diameter, height of standing live trees
    • Diameter, height, and decay class of standing dead trees
    • Volume of harvested wood products
  • Tool: Carbon Calculator

Other Ecosystem Services

  • Purpose:
    • Assess baseline ecosystem health and anticipate management and/or conservation impacts
    • Enter voluntary and/or regulatory
  • Data: Quantitative and Qualitative
  • ToolsWillamette Partnership Field Tools

Featured Member: Still Waters Farm

By the time Beth and Mark Biser bought Still Waters Farm in 1990, the 48-acre parcel of forest in Mason County, Washington was a shell of its former self. Its 20 acres of wetlands had suffered two major disturbances.

2018 Accomplishments by the Numbers

2018 was a productive year for NNRG and the forests our members steward! We are so inspired by the landowners and managers in our community who worked to enhance habitat for threatened and endangered species, removed invasive species, planted a diverse array of native seedlings and shrubs, and pursued new markets for local wood products. These are highlights from 2018.
