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 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
Tree Data Collection Teams of 5 elementary and high school students On site assistance from resource people Data successfully collected on 84 Trees: GPS Coordinates Tree Diameter Tree Height Tree Species Tree Health Tree Growing Conditions
Additional Activities Presentations on “Why Care About Trees?” and “What is a School Forest?” Buckthorn removal White pine bud capping GPS Treasure Hunt
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
