Criterion 3 Maintenance of Ecosystem Health and Vitality:  Criterion 3 Maintenance 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 Criterion 3 Maintenance 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 3 Maintenance 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 3 Maintenance 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 Slide5:  Radiant Energy Chemical Energy LIFE ON EARTH 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 Criterion 3 Indicators Defining Key Phrases Essential to Address Indicators:  Criterion 3 Indicators Defining Key Phrases Essential to Address Indicators Criterion 3----Indicators Example of Possible Wording Changes:  Criterion 3----Indicators Example of Possible Wording Changes Specifics of C3 Indicators from National Report on Sustainable Forests--2003:  Specifics of C3 Indicators from National Report on Sustainable Forests--2003 Criterion 3 Maintenance 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 3 Maintenance 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 3 Maintenance 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 Slide33:  Most data only covered 60+ % of U.S. Slide41:  Damage Crown Condition Mortality Regeneration Soils Down Woody Debris Understory Vegetation Tree Diversity Lichen Communities Ozone Bioindicators Lichen Communities Exotic Species Fuel Loading Slide44:  1=loblolly pine forest; 2=bottomland hardwood forest; 3=mixed hardwood stand; 4=agricultural land; 5 = shortleaf pine plantation. Subplot 1 has 3 condition classes (1, 4, 3); subplot 2 has 3 condition classes (1, 3, 5); subplot 3 has 1 cond. Class (1); subplot 4 has 2 cond.classes(3, 2) Slide45:  Damage Crown Condition Mortality Regeneration Soils Down Woody Debris Understory Vegetation Tree Diversity Lichen Communities Ozone Bioindicators Lichen Communities Exotic Species Fuel Loading
