There will be a musical start to Royal City Rag on June 5; University of Guelph Emeritus Professor, musician, creator of the Guelph Guitar Doug Larson, will be joining us in the first hour (8-9 a.m.) with Thomas Aldridge, owner of Manhattans to talk about M.A.S.H. Mondays, a new collaboration between Manhattans Music Club and the Hillside Festival. Doug will also be playing the Guelph Guitar live for us in the studio.
M.A.S.H. (Music, Art, Science, & History) Mondays will feature interviews and performance from special guests while in conversation with Professor Larson about their many interests.
The shows will be held at Manhattans, 951 Gordon St., Guelph and run from 8.30 – 10.30 p.m. The shows start on Sept. 13, 2010 to be followed on the first Monday of every month (Oct.4, Nov.1, Dec.6, Jan.10, Feb.7, Mar.7, Apr.4).
Guests lined up for the series include:
- Craig Norris(host of CBC R3-30, lead singer of the Kramdens)
- Mike Ford:(musical historian, Canada in Song / Moxy Früvous)
- Bob McDonald:(host CBC’s Quirks and Quarks)
- Samir Baijal:(artistic director, Hillside Festival / musician)
- Alan Wildeman: (President, University of Windsor)
- Jay Ingram: (host, Daily Planet, best selling author)
- Mark Stutman & Matty Cooper: (instrument builder and teacher)
In the second hour, Judy Martin from the Sierra Club Canada and Norah Chaloner from Guelph Urban Forest Friends will join us to talk about the City of Guelph’s proposed new tree bylaw as well provide some follow-up on the city’s Natural Heritage Strategy and Official Plan deliberations.
Guelph Urban Forest Friends have been advocating for our urban trees, including a stronger protective tree bylaw and a separate urban forestry department with a certified forester to more effectively manage tree maintenance and coordinate public education on the value of our mature trees.
Guelph citizens have now been waiting for a new stronger protective tree bylaw for more than 19 years. In the meantime we continue to lose canopy. Guelph’s urban forest canopy sits at 25%, while the desired level is 40%.
Unfortunately the 1986 tree bylaw (view) said it was an offence to injure or destroy any living tree in the City of Guelph but did very little to actually protect them.
The new draft bylaw (view the draft) still needs public input to make sure that it is truly protective.
The City of Guelph has held one workshop (June 3) and has another planned (June 8) to provide input on proposed changes.
The June 8 workshop take place at City Hall, 1 Carden St. in Meeting Room C from 7–9 p.m. Following a presentation, participants will have an opportunity to discuss issues and provide feedback.
About the draft Tree Bylaw
In addition to regulating trees 10 centimetres at breast height on lots larger than 0.2 hectares (0.5 acres), the updated draft bylaw proposes to regulate damage or removal of larger trees on smaller properties; trees 20 centimetres in diameter at breast height on lots less than 0.2 hectares (0.5 acres). The updated draft also includes a permit process, a list of exemptions, entry and inspection powers, enforcement measures and increased fines.
Even if you can’t attend the sessions, you can still comment. Comments will be received until June 18.

Weird Numbers Part 2: The Natural Heritage Strategy Tree Replacement Equation or ‘Two Tens for a Five Anybody?’

Weird Numbers Part 2: The Natural Heritage Strategy Tree Replacement Equation or ‘Two Tens for a Five Anybody?’
Bob Gordon, Freelance Journalist/Royal City Rag Contributor
The Draft Natural Heritage Strategy includes a tree replacement policy that contains two components. The first compenent establishes that any trees removed must be replaced and introduces an equation to calculate the replacement value of a given tree. The second, introduces the concept of cash in lieu of trees.
Unfortunately, the first component is nonsensical while the second is meaningless.
The current draft policies require that if a tree is removed trees totaling an equal diameter must replace it. The example below will demonstrate the absurdity of this mathematical reasoning.
Consider first the removal of a tree of 40 centimeters diameter at breast height. The current policy would permit this tree to be considered replaced if 8 saplings of 5 centimeters diameter at breast height were to be planted.
Briefly consider the area of the tree removed (40 centimeters diameter at breast height). Area = πr2 = 3.14 x (20×20) = 1256 square centimeters.
The area of the 5cm diameter saplings replacing it will be πr2 x 8 = 3.14 x (2.5×2.5) x 8 = 157 square centimeters.
Thus, removal of one tree of 40 centimeters diameter at breast height can be compensated with its replacement by 8 saplings (of 5cm diameter) but only 12.5% of its area.
Now consider replacement of the tree by 16 saplings of 2.5 centimeters diameter at breast height.
The area of these trees will be πr2 x 16 = 3.14 x (1.25×1.25) x 16 = 78.5 square centimeters.
Half Dead Oak Sapling - Now you see me, now you don't!
Thus, removal of one tree of 40 centimeters diameter at breast height can be compensated with its replacement by 16 saplings (of 2.5cm diameter) but only 6.25% of its area.
Clearly, the proposed policy is inadequate.
Comparison of the areas of the crowns of the trees would reveal an even greater imbalance. Leaf Area Index or Canopy Cover is a much more accurate measure. Using this type of measure would significantly increase the number of replacement trees required.
At the very least basal area (area at ground level) should be employed as the replacement standard.
The draft Natural Heritage states, “Where planting either on or off site is not feasible, cash-in-lieu will be required equal to the value of the replacement trees and shrubs and including the cost of planting and maintaining the trees for a period of two years.”
While this proposal may sound wonderfully ‘green’ and hard on developers it is not, nor is it hard on the city. It is hard, only on the urban forest.
Consider, the cash value of a tree will be calculated based on the value of replacement trees. However, in light of the above noted formula the developer is receiving a kiss. Consider that the removal of a single tree may create a whole new building lot at the cost of only a handful of saplings. That is a great deal for a developer but hard on the urban forest.
As far as the city is concerned a cut down tree is a bargain at any price. No where does the policy hold the city to any commitment to spend the cash-in-lieu received on trees. It can go to anything from snow clearing at city hall to trips for councilors or catered meals before meetings. There is simply no guarantee that the money received in lieu of trees will be used for trees and not simply disappear into general revenue.
That is good for the city but not the urban forest.

Guelph Urban Forest Friends have been advocating for our urban trees, including a stronger protective tree bylaw and a separate urban forestry department with a certified forester to more effectively manage tree maintenance and coordinate public education on the value of our mature trees.
If you feel strongly about this issue, please contact Mayor and Council.
Tell them to get the Strategic Urban Forestry Management Plan completed and a strong protective bylaw passed. Let them know that the protection and management of our urban forest will be an election issue this October.
