ELC Tree Inventory and Mapping ProjectPresentation Transcript
ELC Tree Inventory and Mapping Project Fall 2002Funding Provided by the Stillwater District 834 Partnership Plan Project designed by Bob Kondrasuk, Glenn Boettcher, Sandy Pederson and Sara Damon
Project Goals To experience the Stillwater Environmental Learning Center (ELC), a Minnesota School Forest. To learn about the value of trees. To collect data about trees using modern forestry tools. To use Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to map and analyze the environmental, health and economic benefits of ELC trees.
Grant Expenditures - $1200 Forestry Supplies Clinometers DBH Tapes Caliper 100’ Measuring Tapes GIS Software ArcView extension CITYgreen 5.0 School bus transportation for Stonebridge students
Project Participants 27 - 2nd and 3rd grade students from Stonebridge Elementary School 73 - Natural Resources and Human Geography students from Stillwater Area High School
In-Kind Assistance Residents of Boutwell’s Landing ELC Committee Members Bud Buchman & Bob Hagstrom Minnesota Department of Natural Resources Dawn Flinn & Dave Schuller Oak Park Heights Arborist Kathy Widin Tree Trust Rebekah Van Wieren Washington County SWCD Jyneen Thatcher Target Corporation SAHS Grounds Crew
Project Timeline October 4, 2002: Originally scheduled Tree Inventory rained out October 24, 2002: Tree Inventory conducted November 20, 2002: GIS Day – Stonebridge and SAHS Human Geography students enter tree data into CITYgreen database December 2002: GIS analysis

GIS Analysis:What CITYgreen Told Us Carbon Storage and Sequestration: The amount of carbon dioxide removed from the air and stored by the trees. Air Quality: The value of the tree’s absorption and filtering of ozone, sulfur dioxide, nitrogen dioxide, particulate matter, and carbon monoxide (based on estimated externalities of health care and tourism revenue).
CITYgreen Analysis Results Data based on inventory of 84 trees, which comprise .41% of the area of the Environmental Learning Center. Carbon Removal Benefits: Storage Capacity - 1598.30 tons Sequestration Rate - 36.02 tons/year Air Pollution Removal Benefits: O3 (ozone) - 1,399.63, $4,295.49 SO2 (sulfur dioxide) - 195.20, $146.65 NO2 (nitrogen dioxide) - 545.48, $1,674.10 PM10 (particulate matter) - 896.75, $1,837.60 CO (carbon monoxide) - 87.69, $38.15 Total - 3,124.76 lbs. Dollar Value - $7,991.99
