    • A H e a l t h y & G r e e n G u e l p h Guelph Urban Forest Friends
    • Guelph Urban Forest Friends (GUFF) We are a group of citizens working, through education and advocacy, to maintain and increase the health, integrity and area of Guelph’s urban forest.
    • Purpose of presentation
      • To outline the issues harming trees in an urban environment
      • To recommend ways to protect Guelph’s trees
    • How trees benefit a city
      • Improve air quality
      • Combat climate change
      • Reduce UV exposure
      • Reduce energy needs
      • Reduce run-off
      • Enhance groundwater recharge
      • Increase property value
      • Provide habitat
      • Support health and well-being
      • Contribute to community heritage
    • Two similar homes. The house on the left has significantly decreased heating & air conditioning costs, lowering energy demand
    • Removing a healthy tree means less water infiltration and more run-off, degrading water resources with pollution and sediment
    • “ A study in Charlottesvile, VA showed that when tree cover dropped by 8% between 1976 – 2000 the amount of run-off increased by 19%” GRCA Forester Virginia Gauley, GRCA Watershed Report
    • Trees stabilize the amount of after-storm river flow “ Our city needs a stable amount of river water for wastewater management” GRCA Watershed Report “Investing in Trees”
      • Current development and construction practices are damaging for trees
      Urban conditions can be tough on trees Roots are being suffocated
    • Victoria Road, branches have been removed… prior to final cut
    • Victoria Road, heritage home saved… heritage trees removed
    • Places to Grow will bring thousands of new homes to Guelph This infill lot between two houses has 13 healthy trees
    • This is the same infill lot. All mature trees have been removed, including two on city property
    • Same property. Now has increased storm water runoff, higher energy demand and reduced groundwater infiltration
      • Root destruction must be avoided during construction
        • trees must be protected within their dripline
      Urban conditions can be tough on trees Construction on Dublin Street
    • A tree bylaw would protect this tree to the dripline Will this tree be here in five years?
    • A tree bylaw would protect this tree too Will this tree be here in five years?
    • . Soil compaction significantly damages tree root systems
    • Damaged roots mean starvation and early death
    • Urban conditions can be tough on trees
      • Cutting roots during construction increases the risk of toppling
      http://www.mass.edu/urbantree/hazard
    • Newly planted trees are often forgotten Lack of water and protective guards results in greater than 50% loss
    •  
    • An ambient temperature of 26 degrees can increase to 48-55 degrees on paved surfaces. The effects on health are considerable. Shade for Good Health and a Green City, Toronto 2007
    • Best practices include shading paved surfaces
    • Park and yard maintenance can lead to significant damage and shortened life
      • 1991
        • tree by-law must be revised "in order to control the number of trees, woodlots & habitat destroyed annually by development"  ( Park Naturalization Policy )
      • 1994
        • "Methods for protecting trees from development should be developed" ( Green Plan )
      • 2003
        • Environmental Action Plan recommends tree inventory, updating tree by-law to protect natural features and developing guidelines to protect trees during construction
        • Aboud report recommends hiring a professional forester with a degree in forestry or arboriculture
      Guelph’s history of arboreal inaction
      • 2005
        • Council resolution asking staff to prepare funding request for urban forest study and tree maintenance program
      • 2007
        • “ A biodiverse city with the highest tree canopy among comparable cities” ( Strategic Plan Goal 6.6
        • October, Staff report states that “ Urban Forest Management Plan will be finalized with details for implementation and be presented to council in first quarter of 2008”
        • November, Council resolution that staff report back following the visioning process with cost estimate for Urban Forest Management Plan
      • 2008
        • January, Council approves Strategic Urban Forest Management Plan as a priority
      Guelph’s history of arboreal inaction
      • 2009
        • Guelph is still losing trees and canopy due to no urban forest plan or protective tree by-law
        • 18 years of inaction on many plans has removed thousands of trees from our canopy
        • Established urban forestry guidelines recommend 40% tree canopy for cities to reduce the negative effects of climate change on air quality and health
        • Guelph is currently less than 25% canopy
      Guelph’s history of arboreal inaction
    • What our city needs to do
      • Many cities have stronger tree bylaws than Guelph including:
        • Toronto
        • Mississauga
        • Waterloo
        • Richmond Hill
        • Kingston
        • Oakville
        • Barrie
      ~260 year old Maple
    • What our city needs to do
      • Pass an interim tree bylaw without further delay to provide the oversight and control we need to stop further loss of canopy
    • What our city needs to do
      • Complete the Strategic Urban Forest Management Plan
        • trees should be seen as green infrastructure and have value and prominence in all development projects
        • connect trees to water conservation & efficiency
      Bullring, University of Guelph
    • What our city needs to do
      • Establish an Urban Forestry Department
        • hire a certified forester
          • a 2003 City of Guelph report (Aboud and Associates Inc.) recommended that successful tree management requires a professional with college or university credentials in forestry or arboriculture
      Bullring, University of Guelph
    • What our city needs to do
      • Form an Urban Forest Advisory Committee
        • a 2007 City Report recommendation
        • lets protect and develop our green infrastructure as seriously as our grey infrastructure
        • trees are public assets with benefits for all
      Bullring, University of Guelph
    • Before more trees are removed…. In 2009 …give the citizens now and in the future, a gift to remember!
      • Summary:
        • Pass an interim tree bylaw
        • Establish an Urban Forestry Department
        • Hire a certified forester
