Technology and Trees Presentation for APS Science Staff Mary Van Dyke, 15 Feb 2011
A Schoolyard Tree Project • Tree ID • Tree Inventory • Calculate Tree Benefits Online • Map Trees on Google Maps
Why?• Science SOLs • Multi-disciplinary – 4.8 Virginia’s Natural – Tree biology Resources – Urban ecology – 4.5 Ecosystems – Classification – 5.1 Classification key – Quantitative skills (counting• Technology and project- and measuring) based learning – Resources and stewardship• Educate students about urban forests
Technology and Trees - Logistics• Costs and Materials - Minimal Investment – Tree ID books – Diameter “DBH” tapes – Cameras – Computers – Resources Online• Class Time – 4 x 45 min lessons minimum• When – Late March to October optimum
Tree ID• Draw favorite trees from memory, or write a poem• Go outside, look at trees• Identify trees• Make leaf albums

$$ Tree Benefits• Fairfax County estimates its trees provide $54 million of “ecosystem services” annually. (2007).• Arlington County estimates its trees provide $1.8 million in air pollution control and over $6.8 million in storm-water control annually. (2004)• Healthy, mature trees can add 10% to residential property values.
