Return to Table of Contents – Winter 2012 TREE Fund Report

The TREE Fund Board of Trustees recently approved funding for the following new research projects:
John Z. Duling Grants ($10,000)

Dr. Edward Gilman, University of Florida   Tree Response to Pruning Cuts on Branches that Lack Collars Dr. Gilman’s       research seeks to discover how cut size and angle   affects branches without       a visible branch collar, facilitating   recommendations for pruning to       limit the advance of discolored and   decayed wood. |

 Dr. Gary Watson, The Morton Arboretum   Utilizing Space Age Digital Strain Measurement Technology to Identify Zones of Mechanical Weakness in Trees    Dr. Watson is studying       the applicability of NASA’s ARAMIS  stereophotogrammetry technology to       improving our understanding of  tree biomechanics and more accurately       identifying zones of  weakness and potential failure in trees. | 
 
Jack Kimmel International Grants
|  | Matt Follett, University of Quebec at Montreal 
   Effect of Pruning Type on Crown Motion 
 Mr. Follett’s project investigates the effect of thinning and reduction pruning on the dynamic motion of tree crowns. His objective is to provide improved best-practices recommendations for crown pruning, resulting in decreased crown-related failures in mature urban trees. | 
|  | Dr. Alessio Fini, University of Florence 
   Effects of root severance by excavation on growth, physiology and uprooting resistance of two urban tree species 
    Dr. Fini is studying the effects of root damage on tree growth, stability and physiology, comparing two species thought to differ in tolerance to root manipulation, and investigating how localized root damage affects the leaf gas exchange of the entire canopy. |
