  3. Why bother?

  4. Sustainability: "We can't drive our SUVs … and keep our homes on 72 degrees at all times.” "I propose a limitation be put on how many squares of toilet paper can be used in any one sitting." Conservation

  5. Sustainability: Technology

  6. Sustainability: Trees!

  7. Ecosystem services Energy conservation Air pollution reduction Stormwater management Carbon dioxide reduction

  8. Why bother?

  11. Why bother?

  12. Alright, you’ve convinced me it’s important, why isn’t it done?

  20. Design features • Client-independent • Data publicly owned and accessible • SQL-based and web-based data access

  21. The Plan Begin by pulling data on the large scale

  22. Data sources

  23. Data sources kcolwell flickr

  24. Attributes • Species • Diameter • Address • Lat/long coordinates • Planting date • Landmark/protected/special status • Size of the growing space • Condition • Gray infrastructure conflicts • Recent maintenance • Sponsors

  25. The Plan Begin by pulling data on the large scale Enable data entry on the small scale

  26. Crowd sourced data kcolwell flickr • Attributes • Photo • Identify caretaker • Maintenance needed • Maintenance completed • Notes, stories, poems

  27. User profile • Name or userid • Photo • Neighborhood • Tree expertise • Running score

  28. The Plan Begin by pulling data on the large scale Enable data entry on the small scale Track changes and notify up the chain

  29. Track Changes

  30. The Plan Begin by pulling data on the large scale Enable data entry on the small scale Track changes and notify up the chain Queries and reporting

  31. Tree model • Species • Fruiting/flowering • Native vs nonnative • Invasive • Habitat

  32. Ecosystem services model • Species and diameter • Energy conserved • Air pollutants reduced • Stormwater managed • Carbon dioxide reduced • Property values increased

  33. The Plan Begin by pulling data on the large scale Enable data entry on the small scale Track changes and notify up the chain Allow searches and reporting Assess data quality

  34. The Plan Begin by pulling data on the large scale Enable data entry on the small scale Engage the community Track changes and notify up the chain Allow searches and reporting Assess data quality

  35. Community involvement Tree huggers • Testing/bug reports • Data collection • Tree planting and caretaking Developers • Testing/bug reports • Server-side plug-ins • Client apps

  36. Statistical analysis Server-side plug-ins

  37. Spatial analysis Server-side plug-ins

  38. Potential conflicts with solar panels Flickr: Brylyn Server-side plug-ins

  39. Leaf recognition software = ≠ Server-side plug-ins

  40. iPhone Add-a-tree Client apps

  41. Urban grazing Client apps

  42. Create a Tree-Walk Client apps

  43. Find a tree-hugger Client apps

  44. The Future • Beyond computers • Beyond trees • Beyond San Francisco • Beyond data collection

  45. The Urban Forest Map Project www.urbanforestmap.org kelaine@urbanforestmap.org The best friend on Earth of man is the tree. When we use the tree respectfully and economically, we have one of the greatest resources of the Earth. --Frank Lloyd Wright

  46. One tree in a Sacramento front yard: ~600 kWh/year = $65 Energy conservation

  47. One tree in a Sacramento front yard: ~600 kWh/year = $65 5.5 lbs/year = $40 Improving air quality

  48. One tree in a Sacramento front yard: ~600 kWh/year = $655.5 lbs/year = $40 2,500 gals/yr = $20 Improving stormwater

  49. One tree in a Sacramento front yard: ~600 kWh/year = $65 5.5 lbs/year = $40 2,500 gals/yr = $20 280 lbs/year = $5Total stored 4–10 tons~$110–280 Reducing carbon dioxide
