2 Putting Forest Service Science into People s Hands Public Domain Software Accessible Technical Support Development, Dissemination, Support, Refinement

3 Trees Pay Us Back Trees are assets, management adds value by increasing return on investment

4 i-tree v4.0 Update Scott Maco Manager of Ecosystem Services, The Davey Institute

5 i-tree: Demonstrating That Trees Pay Us Back!

6 A Benefit-Based Assessment Economic Value Strategic Management Environmental Services Structure

7 i-tree Putting USFS Urban Forest science into the hands of users Credible, USDA FS peer-reviewed tools Public Domain Software Accessible Continuously improved

8 What s are they using? i-tree Eco assesses: Structure Function Energy Air pollution Carbon VOC emissions Value Management needs Pest risk Tree health Exotic/invasive spp.

9 v4: New Tools & Enhancements <- Field Data -> Web Desktop Web Module Desktop Pest Detection

10 i-tree Design Parcel level analysis of individual trees General public use Web accessible by all

12 i-tree user base continues to grow City foresters Consultants Non-profits Universities Homeowners Planners U.S. benefit analysis snared $220m for trees Horticulture Week (10/1/2009)

13 Hydro David J. Nowak Project Leader USDA Forest Service Northern Research Station Syracuse, NY

14 Hydro Model that answers - How do changes in: Tree cover Impervious cover affect: Stream flow (flooding) Water quality (TMDLs)

15 Watershed based simulations of hourly changes in: Stream flow Water quality Hydro Elevation High Low

16 Required Data: Stream flow Hydro

17 Required Data: Stream flow Weather Hydro

18 Required Data: Stream flow Weather Digital Elevation Maps Hydro

19 Required Data: Stream flow Weather Digital Elevation Maps Cover information Canopy Hydro

20 Auto-calibrate model: Solves for best fit of soil and other parameters Hydro

21 Model Scenarios - you pick, for example: Change tree cover Change impervious cover Hydro (comparing scenarios side-by-side)

22 Model Scenarios - you pick, for example: Change tree cover Change impervious cover Hydro (differences in scenarios)

23 Model Scenarios - you pick, for example: Change tree cover Change impervious cover Hydro (tabular outputs)

24 Model Scenarios - you pick, for example: Change tree cover Change impervious cover Hydro (changes in water quality)

25 Hydro Reasons to run model: Understand the effect of trees on: Flooding Water quality Upcoming versions: Snow melt Radar-based precipitation Non-watershed based

26 How Communities are Using i-tree Jerri J. LaHaie, CAE, Executive Director Society of Municipal Arborists

27 Milwaukee i-tree Eco Assessment EAB Structural Impacts: 17.4% Canopy Loss $221 Million structural damage (citywide) EAB Functional Impacts: $243,785 less pollutant removal $138,000 less energy savings (cooling costs) $2.6 million reduction in storm water benefits (1996 study)

28 Milwaukee Ecosystem Assessment

29 Chattanooga, Tennessee

30 Oakville, Ontario

31 Oakville UF SWOT Analysis Strengths Administrative Support Funding Partnerships Weaknesses Lack of time No UF management plan No existing inventory No understanding of UF ecosystem service value Opportunities Integrate UF in policy formation Increase strategic decision making Determine resource at risk Threats Loss of UF program relevance Emerald ash borer Lack of cooperation between departments

32 Oakville Policy Advances Integration of UF with air quality and climate protection initiatives Extent of resource at risk to EAB By-laws to protect large stature trees on public & private property Strategic planting decisions
