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 table below identifies various monitoring protocols you can use on your forest, including links to field forms.

Monitoring Tool Purpose Applicable Ecosystem Data Collection Variables Forms
Forest Inventory
  • Determine baseline stand and timber information
  • Comply with FSC monitoring requirements (Indicator 8.2).
Any Quantitative – Statistical sample and permanent plots
  • Tree species, diameter, defect, height, and age
  • Sapling species and diameter
  • Shrub species and % cover
  • Number of snags.
Trees

Sapling and Shrub

Inventory Analysis (to calculate trees per acre, etc)

Forest Stand
  • Track important ecological and physical attributes through time.
Any Qualitative – Walk transects through the forest
  • Forest health and ecological hotspots
  • Wildlife
  • Trees and shrubs
Stand Assessment
Roads
  • Detect and track road deterioration, maintenance needs, or negative environmental impacts.
Any Qualitative -Traverse road segments
  • Road issues and severity
  • Maintenance needs
  • Appropriateness of culvert size compared to stream
  • Passability of culverts on fish bearing streams
Roads
Streams and Wetlands
  • Track general stream conditions and detect any detrimental disturbance impacts.
Any Qualitative – Walk stream segments and around wetlands
  • Channel and wetland characteristics
  • Water quality
  • Vegetation
  • Stream organisms
  • Wetland wildlife
  • Large woody debris
Streams

Wetlands

Biodiversity
  • Identify areas of high biological value
  • Monitor impacts of conservation and/or harvest activities
  • Comply with FSC monitoring requirements (Indicators 6.1, 9.4).
