Now, 11 trees removed for the new house.
Once there were 11 trees...
...now removed and replaced...
- no area of the property reserved for groundwater recharge .
- increased stormwater runoff for decreased river quality.
- increased energy of all three houses for air conditioning
- sump pump needed by neighbours
- ‘heat island’ effect on the street
- more carbon in air with decreased air quality in community
This is a great idea. Well worth repeating. Pressure needs to be put on the City of Guelph to complete its own urban forest plan without further delay.
“Project will create an urban forest – Cities in the GTA plan together to improve tree canopy, beautify region and enhance air quality”
Toronto Star, October 11, 2008
Hundreds of thousands of new trees, planted to create winding city forests and leafy boulevards, will transform Greater Toronto into a vast urban garden if the combined vision of regional foresters succeeds.
The prospect of a greener city visually and environmentally – trees are a major factor in reducing pollution – has urban foresters across the region co-operating on projects that will count each city’s existing trees and calculate the air quality improvement if more are planted along roads and ravines.
Richard Ubbens, Toronto’s forestry director, said his department is working with surrounding municipalities on a complete inventory of public and private trees, as each city creates a master plan to enhance its “tree canopy,” which many expect to double in 50 years.
The tree inventories, using a U.S. research model, will be conducted by each city over roughly the same period of time, Ubbens said.
Trees reduce carbon emissions, promote energy conservation and create a more livable community, particularly if native species are planted in areas where they are most likely to thrive, Ubbens says.
“It is important that this not be an island,” Ubbens said. “As big as Toronto is, or as big as the area of Oakville is, it is still only one little area.
“If we disregard the Oak Ridges Moraine, if we disregard the remnant forest woodlots in York Region … then we are putting the state of the environment, such as it is, at great risk.
“There are a great many connections in the natural environment – not only water, but also habitat and use – so it is important to know that if Toronto is increasing our canopy, that the areas around us are doing something similar.”
Oakville has already conducted its inventory, numbering its urban forest at 1.9 million trees with a canopy coverage of 29.1 per cent of the town, said John McNeil, Oakville’s manager of forestry.
Honoured as the Forest Capital of Canada last year by the Canadian Forestry Association, Oakville hopes to increase its canopy to 40 per cent by mid-century, McNeil said. It’s working with various town departments to make sure trees take priority. McNeil points out that, “by definition, urban trees are under a lot of stress,” especially those surrounded by concrete.
Toronto, whose tree coverage was estimated in 2003 at just 17.5 per cent, has already started a massive planting project, with plans to roughly double the canopy by 2050 as part of a broader project to “green” the city. Equally important is to improve the watering and pruning of existing trees, he said, so they survive and grow bigger: “Our maintenance program has been very far behind for many, many years, but we have been catching up slowly with more money.”
Toronto will plant 100,000 new trees along roads and ravines this year, Ubbens said, but it doesn’t have the data it needs yet to develop a comprehensive plan. Its official tree census began in summer and should be complete in early 2009.
Called UFORE – for Urban Forest Effects – the method being used in Toronto as well as Oakville was developed by the U.S. Department of Agriculture.
It’s used to calculate the number of trees in an area, their size, species, leaf area and health. It also estimates the amount of pollutants removed by trees and air quality improvement through the year. And it estimates the effects of trees on building energy use, along with the consequent reduction in emissions from power plants.
Oakville’s study, for example, determined that its trees filtered all the PM10 – particulate matter that combines with ozone to form smog – emitted by local industries. In a single year, Oakville’s trees also removed 22,000 tonnes of carbon dioxide – equivalent to 4,880 vehicles.
Ubbens said Toronto has increased spending on its trees by $5 million over the past several years, devoting $25 million to city forests.
Certain species do very well in Toronto’s climate – oaks, maples, the fast-growing Kentucky coffee tree. Diversity is key, Ubbens said, especially when destructive insects like the emerald ash borer threaten to wipe out certain species.
Once the UFORE study is complete, the city will finalize its master tree plan, creating, ultimately, a city that makes residents feel like they are “living in a garden,” he said.
“It is spectacular.”

Heritage Home After All The Heritage Trees Have Been Removed
Natural Heritage Strategy Workshops
March 24-25, 6.30 – 9.30 p.m.
The City of Guelph has announced that Natural Heritage Strategy Workshops will take place on March 24-25 at the Holiday Inn, 601 Scottsdale Drive, Guelph.
Community members are encouraged to submit comments as the City refines Guelph’s Natural Heritage Strategy.
The Natural Heritage Strategy aims to identify Guelph’s significant natural areas and ensure their long-term protection and enhancement. Residents and community members are invited to comment on the finalization of Phase 2 of the City of Guelph Natural Heritage Strategy.
Have your say
Workshop participants are asked to select one of the two meeting dates and attend the entire session to review and comment on the natural heritage criteria, mapping and policy direction.
6.30 – 6.45 Opening Remarks
6.45 – 7.30 Presentation
7.30 – 8.30 Working Session
8.30 – 9.00 Group Feedback
