This enables a decision process to determine which service or set of services is valued most highly and how to develop approaches to maintain services by managing the system sustainably.” (Millennium Ecosystem Assessment 2005)3Executive SummarySummary of findings and recommendations• UBC’s Core Resilience Challenges:• Stormwater management and cliff erosion• Biodiversity protection• Urban Heat Island Effect (UHI)• Carbon sequestration• Health and wellbeing• Brand protection• Use economic models to evaluate the monetary return on these important ecosystem services• Assess methods for managing ecosystem services long-term and compensating for the loss of trees due to campus development• Increase engagement with and awareness of UBC’s urban forest4Current Tree Management Practices at UBCUBC does not consider ecosystem services for tree protection• Trees are explicitly protected for…• “Star tree” status• A few designated open spaces• Individuals at UBC are working to develop an Urban Forest Management Plan5Our Resilience ChallengeGoals and Objectives1. Identify and assess ecosystem service evaluation models2. Identify how UBC can systematically and appropriately compensate for the loss of ecosystem services 3. Identify examples of cities and institutions that have implemented an urban forest assessment and management plan4.

Measure Current UTC2. Estimate Potential UTC3. Adopt a UTC Goal• American Forests’ Vibrant Cities Lab• Includes research, case studies, and tools resourcesAlternative to a Compensation Model:Proactive ManagementBiodiversity Targets• City of Melbourne: • “increasing forest diversity with no more than five percent of one tree species, no more than ten percent of one genus and no more than 20 percent of any one family”  (Melbourne Urban Forest Strategy)• University of Melbourne: • Conducting a baseline biodiversity assessment, so that it can implement a “no net loss” policy• Maintain or increase tree diversity, while particularly selecting species with climate resilience in mind• (University of Melbourne Biodiversity Management Strategy)15Case Studies16City or Institution Current canopy cover Canopy cover target Hyperlink 🔗🔗Vancouver, Canada 18 % Plant 150,000 trees by 2020 linkEdmonton, Canada 10.3 % 20 % linkKelowna, Canada 13 % 25 % linkOakville, Canada 29.1 % 30 % linkOttawa, Canada 25 % 30 % linkToronto, Canada 26.6 - 28 % 30% linkCase Studies (continued)17City or Institution Current canopy cover Canopy cover target Hyperlink 🔗🔗Portland, OR, USA 26.3 % 35-40% (residential areas), 15% (industrial/commercial), 30% (parks, open space), and 35% (rights-of-way)linkSeattle, WA, USA 18 % 30 % (with specific targets for each land use category) linkVancouver, WA, USA 19.7 % 28 % linkMelbourne, Australia 22 % 40 % linkUniversity of Washington 28.6 % [In research phase] linkUniversity of Maryland 24 % 40 % linkUniv of California, San Diego 12 % 40 % linkCampus EngagementCurrent Students● Arbor Day or National Forest Week○ E.g.

What are you managing for?• Consider potential opportunities to explore forested roofs, which could integrate the built and forested environments21AcknowledgementsWe’d like to send a special thank you to all who have supported the development of our team’s recommendations. In particular, we appreciate the guidance and support from our instructors, José Puppim de Oliveira and Murali Chandrashekaran, as well as the opportunity to investigate this resilience challenge from John Madden. Individuals such as Jeffrey Nulty, Dean Gregory, Cathy Pasion, David Gill, Jennifer Rae Pierce and Doug Doyle were also indispensable during our learning and discovery process.22
