Transcript

  • 1. 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
  • 2. 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.
  • 3. 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
  • 4. Project Participants  27 - 2nd and 3rd grade students from Stonebridge Elementary School  73 - Natural Resources and Human Geography students from Stillwater Area High School
  • 5. 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
  • 6. 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
  • 7. Stillwater ELC is aMinnesota School Forest
  • 8. Our Study Area
  • 9. 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
  • 10. Additional Activities Presentations on “Why Care About Trees?” and “What is a School Forest?” Buckthorn removal White pine bud capping GPS Treasure Hunt
  • 11. GIS Analysis - ELC Boundary
  • 12. GIS Analysis – Non-canopy
  • 13. GIS Analysis – GPS Points
  • 14. GIS Analysis – GPS Points
  • 15. GIS Data Entry – Tree Data
  • 16. GIS Analysis - Canopy
  • 17. 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).
  • 18. 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
