I YOUR COMMllTEE RECOMMENDS:

Tree 1, (7) That the following actions be taken with respect to tree watering: Watering

Stanford, Division Manager, Environmental Programs and Customer Relations; it being noted that 77,000 households with Ash trees are currently under quarantine; it being further noted that the Canadian Food Inspection Agency (CFIA) is the lead Agency on the Emerald Ash Borer program and has approved the set-up of a depot in east London to accept infected ash trees.

(4)

.-

LongTerm 4. (5) That the Trees and Forests Advisory Committee (TFAC) deferred discussion of its long term plan for the trees and forests in the City of London to a

Forests in the future meeting in order to allow staff time to incorporate the 'brainstorm session' city Of titles and ideas in preparing the framework for an Urban Forest Strategy; it being

noted that A. Macpherson, Manager of Parks Planning and Design provided the attached Community Forestry Report with respect to community plantings in City parks to assist the TFAC in setting its goals as it pertains to this matter.

Ecological 5. (6) That the Trees and Forests Advisory Committee (TFAC) held a discussion with respect to the value of ecological lands; it being noted that the TFAC referred this matter to its Save More Sub-committee for further review; it being further noted that the Sub-committee would look into such matters as, but not limited to, Green Infrastructure and Ecological Gifting.

Fall Planting 7, That the Trees and Forests Advisory Committee (TFAC) heard a verbal update from A. Macpherson, Manager of Parks Planning and Design, with respect to a fall planting proposal to focus on planting more trees in areas of the City that are dominated with Ash trees; it being noted that funds have been allocated for additional tree planting to combat the Emerald Ash Borer and a tender is expected to go out in spring to be ready for the fall tree planting season; it being further noted the TFAC asked staff to circulate the proposed fall planting proposal at its next meeting.

The Urban Forest Effects Model (UFORE), designed by the United States Department of Agriculmre, Forest Service (USDA Forest Service), has been used to quantify urban forest structure and nuniei'ous urban forest effects in cities across the world. Randomly gencrated saniplo plots combined with local pollution and weather data measure the air quality benefits provided by trees, shrubs and other types of vegetation gi-owing throughout Oakville. These benefits are then converted to their economic value. Over the suminer of 2005, approximately 500 residents and businesses paxticipated in IheTown's UFORE project. A total of 372 plots were measured. Through UFORE, a scientifically sound analysis of the stnichlre, function and value of Oakville's urban forest including its role in greenhouse gas mitigation is provided for the first time (Section 7).

The results of the Town's UFORE project will provide support and background for the Town's Urban Forest Strategic Management Plan - a major 2006 project of the Parks and Open Space Department. Urban forest canopy cover targets will optimize the potential benefits trees provide to our ccosystern. In order to rcalizc this potcntial, it is essential for the community to plui, design and maintain an urban forest as grcen infrastructure. Research has concluded that most of the benefits are derived fi-om large-stature trees (McPherson 2004) and woodlots (Nowak 2006). New urban design techniques and managenlent approaches lo realize these potentials are presented in Section 9. Next steps arc summarized in Section 10.

UFeR Project Summary: c”l

Urban FGrest Effects Model Introduction The Urban Forest Effects (UFORE) model is designed to use standardized field data from randomly located plots, and local hourly air pollution and meteorological data to quantify urban forest structure and numerous urban forest effects for cities across the world. The model currentlv auantifies: .

. c ” .

Urban forest structure by land use type (e.g., species composition, tree density, tree health, leaf area, leaf and tree biomass, species diversity, etc.). Hourly amount of pollution removed by the urban forest, and its associated percent air quality improvement throughout a year. Pollution removal is calculated for ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide and particulate matter (4 0 microns)’. Hourly urban forest volatile organic compound (VOC) emissions and the relative impact of tree species on net ozone and carbon monoxide formation throughout the year*. Total carbon stored and net carbon annually sequestered by the urban forest3. Effects of trees on building energy use and consequent effects oncarbon dioxide emissions from power plants4. Compensatory value of the forest, as well as the value of air pollution removal and carbon storage and sequestration5. Potential impact of Gypsy moth and Asian longhorned beetle infestation. Tree transpiration’.
