<P>Hello,</P>
<P>I am a part-time student in the Master of Forest Conservation program at U
of Toronto and I will be completing my final research paper this coming fall
semester. I have been doing studies for the Town of Cobourg throughout
this program including tree inventory, EAB Management Plan and coordination of
their Heritage NeighbourWoods pilot program this past summer with the town
arborist. </P>
<P> </P>
<P>I am starting to conduct background research for my final paper which will
focus on mature and heritage tree preservation and management
options. I am looking at mature boulevard trees in the heritage
dristrict as well as mature trees in Victoria Park along the Cobourg
beach. Of particular concern are the park trees and the impact of
increased park use and major festivals primarily relative to soil
compaction. There has also been media attention lately surrounding the
impact of 'Ribfest' due to heat and grease. The main park study area has
recently seen the death of two mature elms due to DED and branch union failure
of large silver maples. The remaining mature trees are primarily silver
maple, a butternut and some massive cottonwood along the boardwalk which have
been getting attention as heritage candidates from council and the
community. </P>
<P> </P>
<P>I have not yet found much background information, guidelines or
precedents on managing user impacts in public urban parks and would appreciate
any experience or insight this group can share. The Town has started
doing some investigation this year including compaction testing around
trees. Testing leading up to the Canada Day festival in dry conditions
revealed extreme compaction. This will be an ongoing study to gather data
under various conditions in spring and fall. There are also discussions
about mitigation measures such as radial excavation and mulching. </P>
<P> </P>
<P>I appreciate any feedback. </P>
<P> </P>
<P>Many thanks! </P>
<P> </P>
