Criterion 3Maintenance of Ecosystem Health and Vitality: Criterion 3 Maintenance 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.


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. Criterion 3 Maintenance of Ecosystem Health and Vitality


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. Criterion 3 Maintenance of Ecosystem Health and Vitality

Conceptual Model for Criteria of Montreal Process Criteria and Indicator: 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
