Exploring Urban Forestry Modeling and Prioritization Tools

The Urban Forest Modeling and Prioritization Toolkit is a prototype web-based tool that enables users to generate heat maps identifying key planting locations and then estimate the long-term impacts of trees planted in those locations.

This webinar was held on June 28, 2012 and provides an overview of the research and initial features of the system.

  3. 3. Agenda • Azavea Background • Urban Forest Modeling and Prioritization Toolkit • Finding Prioritized Planting Locations – Research review – Identifying key locations • Modeling Future Benefits – Research review – Estimating long term impact • Questions
  4. 4. About Azavea • Founded in 2000 • 30+ people • Based in Philadelphia – Also Boston & Minneapolis • Geospatial + web + mobile – Software development – Spatial analysis services – User experience
  5. 5. Research-Driven • 10% Research Program • Academic Collaboration B Corporation • Pro Bono Program • Donate share of profits • Projects w/ Social Value • Open Source
  6. 6. Azavea and Urban Forestry An open source tree data management system for collaborative, geography enabled urban tree inventory www.opentreemap.org
  7. 7. High Performance Geoprocessing • GeoTrellis – an open source geographic data processing engine • Breaks big projects into small distributed tasks • Makes geographic analysis really, really fast • Helps create web-based heat maps
  8. 8. How Is It Used?
  9. 9. Urban Forest Modeling and Prioritization Toolkit
  10. 10. Goals
  11. 11. The Main Questions How do we identify key tree planting locations based on a variety of factors? How do we begin to estimate the long term impacts of trees planted in a certain location?
  12. 12. Urban Forestry Modeling and Prioritization Toolkit • Funded with a USDA Small Business Innovation Research Grant • Focuses on identifying prioritized tree planting locations • Recognizes people have different planting priorities • Enables users to set adjustable factors in order to create customized heat maps • Calculates the thirty year benefits of trees planted in a certain area using growth/mortality rates and iTree
  13. 13. Finding Key Locations
  14. 14. Previous Research
  15. 15. Factors that Can Influence Planting Tier 1 – Need Based Criteria • Air Quality/Noise Pollution – Major Road Density • Biodiversity – Ecological Corridor Density – Existing Habitat Density • Public Health – % of Population Sedentary, Obese, Diabetic, Asthma • Water – Flood Density – % Impervious Service Locke, D.H., M.Grove, J.W.T. Lu, A. • Urban Heat Island Troy, J.P.M. O’Neil-Dunne, and B. Beck. 2010. Prioritizing preferable locations for – Max. Avg. Surface Temp. increasing urban tree canopy in New York • Socioeconomic City. Cities and the Environment – Income 3(1):article 4. – Crime
  16. 16. Additional Factors • Tier 2 – Suitability Based Criteria • Based on interests of a particular organization • May include factors such as – Street trees vs. backyard trees – Protected habitats – Natural areas vs. developed areas Locke, D.H., M.Grove, J.W.T. Lu, A. Troy, J.P.M. O’Neil-Dunne, and B. Beck. 2010. Prioritizing preferable locations for increasing urban tree canopy in New York City. Cities and the Environment 3(1):article 4.
  17. 17. Opportunity, Capacity, Impact Nowak, D. and E. Greenfield. 2009. • Population Density Urban and Community Forests of the • Canopy Green Space Mid-Atlantic Region: New Jersey, New York, Pennsylvania. United States • Tree Canopy Cover Per Department of Agriculture, Forest Capita Service, Northern Research Station, General Technical Report NRS-47. We looked at this in terms of: • Opportunity – Places trees could be planted • Capacity – People to care for trees • Impact – Trees will effect desired factors
  18. 18. Identifying Locations
  19. 19. Where to get the data? • Major streets • American Community • Mass transit routes Survey data • Habitat ranges • Police crime data • Protected lands • Impervious surface • Land cover/tree canopy • U.S. Geological Survey slope • Asthma data data • Obesity data • DVRPC Degrees of Disadvantage info • Flood zone maps • Pennsylvania Horticultural • Sewershed overflow events Society TreeTenders’ areas • Landsat imagery
