1 Ecosystem Services of Trees Jacinda Mainord, Inupiat Graduate Student School of the Environment Portland State University


3 Bonan 2008 Forests cover ~42 million sq. km and store about half of the terrestrial carbon Tropical and temporal forests responsible for most of the carbon sequestered

4 Approximately 33% of anthropogenic carbon dioxide emissions are sequestered from forests (Bonan 2008)

5 Evolution of Climate Models Atmospheric modeling – Using energy fluxes, moisture, and atmospheric physics and dynamics Hydrologic cycle – Effects of vegetation on energy and water fluxes Incorporation of plant physiology theory – Biological control of evapotranspiration coupled with hydrometeorology and biogeochemistry


7 Ecosystem Service- Benefits people obtain from ecosystems Products ie. Food, fuel, fiber Regulation and Disease Control ie. Climate control Supporting Services ie. Nutrient cycling Cultural and Aesthetic Benefits MA, 2005

8 What are the Ecosystem Services of an Urban Forest? Benefits Stormwater interception Carbon sequestration Air Quality Aesthetics Biodiversity Psychological Cultural Reducing energy use due to shading Disbenefits Initial investment Maintenance – Pruning – Fertilizers & water – Leaf litter removal – Sidewalks Pests Emissions of BVOCs and N 2 O Property damage Obscuring vistas & sunlight

9 What are the Cultural Ecosystem Services of a Forest?

10 Outline of Ecosystem Services Carbon Sequestration Air Pollutant Removal Rainwater Interception Biogenic Volatile Organic Compound Emissions

11 Carbon Sequestration and Storage Atmospheric carbon fixed through photosynthesis Carbon is lost through respiration and decomposition Leaf and twig drop add carbon to soils Nutrient uptake of soil carbon

12 Air Pollutant Removal Carlson 2003 Uptake through leaf stomata Deposition on tree surfaces

13 Biogenic Volatile Organic Carbon Emissions Trees emit isoprenes and monoterpenes Largest source of volatile organic compounds Role in ozone and carbon monoxide formation Role in haze formation

14 Stormwater Interception

15 Differences in Ecosystem Services  Species Distribution  Age Distribution  Regional Differences  Meteorological and pollutant variations

25 Project Description At 5, 10, and 20 Years from Planting, Project: Carbon sequestration and carbon storage Air pollutants removal (specifically NO 2, SO 2, Particulate Matter (PM), and Volatile Organic Compounds (BVOC)) Rainfall interception

26 Background Work Gather growth equations for trees planted Develop database projecting crown width, crown ratio, and height at DBH growth stages Populate i-Tree Eco database with projected tree metrics Run projected tree scenarios
