Criterion 3Maintenance of Ecosystem Health and
Vitality

• Indicator 15 Biotic Abiotic Stressors
• Bill Ciesla Andy Mason and John Coulston
• Indicator 16 Air Pollution
• John Coulston
• Indicator 17 Ecological Processes
• Mark Ambrose
• Criterion 3 Lead
• Ken Stolte

2
Criterion 3Maintenance of Ecosystem Health and
Vitality

• Indicator 15
• Area and percent of forest affected by processes
  or agents beyond the range of historic variation
  e.g. by insects disease competition from exotic
  species fire storm land clearance permanent
  flooding salinization and domestic animals.

3
Criterion 3Maintenance of Ecosystem Health and
Vitality

• Indicator16
• Area and percent of forest land subjected to
  levels of specific air pollutants (e.g. sulfates
  nitrate ozone) or ultra violet B that may cause
  negative impacts on the forest ecosystem.

4
Criterion 3Maintenance of Ecosystem Health and
Vitality

• Indicator 17
• Area and percent of forest land with diminished
  biological components indicative of changes in
  fundamental ecological processes (e.g. soil
  nutrient cycling seed dispersion pollination)
  and/or ecological continuity.

Conceptual Model for Criteria of Montreal
Process Criteria and Indicator

• Assumptions
• All forces (biological and abiotic) prior to 1500
  are natural and a part of the development and
  maintenance of healthy and sustainable forest
  ecosystems
• Effects of new or exacerbated natural forces
  (latter resulting from human activity) affect
  ecological processes negatively
• Effects on ecological processes if great enough
  directly affect one or more components of forest
  ecosystems e.g. productivity soils and/or
  aquatic ecosystems
• Effects on any one component of a forest
  ecosystem (productivity soils or water) will
  affect the other two components over varying time
  periods
• Criteria 3 New Organization
• Ind. 15 is group of all human-induced (new)
  stressors
• Ind. 16 is group of all exacerbated natural
  stressors
• Ind. 17 is ecological processes and relevant
  indicators
