1) Dr. David Maclean, Fredericton, NBGIS Spatial Analysis, Supporting carbon sequestration. The research will allow us to develop a computer system in which data on current and potential urban forest inventory can be used to calculate carbon sequestration and estimate how optimized urban forestry can help offset GHG emissions data within a specified urban area. This information will provide a tool with which municipal planners and arborists can promote the need and subsequent development of optimized urban forests, and potentially help lever carbon credit funding to assist with reforestation projects.
2)  Dr. Brenda Murphy, Brantford ON. Climate Change SOS Save Our Syrup. The purpose of this project is to educate Canadian youth about the potential impacts of climate change facing this industry, with a focus on solutions and values for youth to adopt climate friendly behaviours. This project will further enable twelve classes of grade 9-10 students to participate in the Climate Change SOS: Save Our Syrup!, and to facilitate the associated Knowledge-Attitudes-Behaviour research to assess the efficacy of the program. PPT Report
3) Dr. Shelley Hunt, University of Guelph Arboretum, ON.  ElmTree Recovery Phase 2. The purpose of this project is to move forward with the second phase of the elm recovery work by augmenting existing seed orchard for DED-tolerant American elms at The Arboretum, University of Guelph. The initial screening program has identified 60 elm clones (out of 281 tested) that show exceptional promise in terms of DED tolerance. Several of these are represented in a preliminary seed orchard and  are now ready to be added to the remaining exceptional clones. The objective in 2014 is to propagate (though grafting) several replicates of each of the remaining DED-tolerant clones for eventual planting into the seed orchard. This will strengthen the existing archive of this genetically diverse group of DED-tolerant elm clones and set the stage for the production of seed containing traits of these ‘super trees’. 


1) Future Schoolyard Forests: Alice Casselman, ACER, The Association for Canadian Educational Resources. Objectives: To raise awareness of how climate change impacts our urban forests through establishment of a Planting for Change (P4C) new schoolyard site; to carry out data analysis, carbon sequestration calculations and interpret the results; and to publish a report to include 20 ACER P4C schoolyards located around the Golden Horseshoe.

2) Tensile Strength Loss in Climbing Ropes: Dan Cooper, Sir Sandford Fleming College. Objectives: To test the limits of climbing and rigging lines of various diameters and constructions; to create a comprehensive chart for rope retirement criteria; and to possibly have the data included as a companion in Samson’s Rope Retirement Guide. Also, to focus on the forces created on knots that are predominately used in rigging and tree dismantling applications and determine if these knots stand up to CSA standards.  

3) Condition and Health of Urban Tree Species: Danijela Puric Mladenova, University of Toronto. Objectives: To use the NeighbourWoods tree inventory program’s standard dataset of over 100,000 trees to conduct a species-specific analysis of tree condition and problems associated with tree size (age), growing space, location and geographic area. The analysis will allow researchers to identify and isolate problems that certain urban tree species may experience in different geographic areas, on public vs. private lands, and problems that start at different age (size). To provide a better ecological understanding of the most commonly planted trees species in Ontario and isolate favourable conditions of some less common species. 

4) Tornado Restoration Research in Goderich: Rachel White, Huron County. Objectives: To monitor regeneration and restoration approaches in one urban versus multiple rural woodlots that were replanted as part of the tornado restoration efforts; to study the viability of assisted migration of tree species from the Carolinian Zone beyond the historical northern limit by monitoring survival and tree health over time; and to determine the efficacy of tree shelter products (e.g. Tubex tree shelters) for preventing seedling/sapling deer browse in woodland plantings.

1) Planning for Change, ACER
Ongoing training of students and volunteers to collect scientific data on annual tree growth and local climate enables ACER (Association for Canadian Educational Resources) to monitor changes on local plots. Community-based data collected by ACER uses international protocols and therefore can provide the basis for projecting the future outlook for Ontario’s trees. Plans for a three day summer workshop include lectures on leading edge climate change modelling, in collaboration with Environment Canada, and hands on training for monitoring climate change, planting, forest biodiversity plots, and restoration ecology.

2) Arborist Knot Testing – Phase 2, Humber Arboriculture Program
Many arborists rely on the safety of knots in their rigging systems when lowering branches or blocks of wood to the ground. Although these knots are used as attachment or anchor points on a regular basis, we should know if the knots provide sufficient strength and also meet the CSA standard. Testing of them would allow arborists to better understand reactionary forces that are applied during this process. This proposal from the Humber College Arboriculture Program involves testing of rigging knots and termination knots, and the results will be passed on to the Arborist Safe Work Practices Committee to be considered for inclusion in the next reprint of the Arborist Safe Work Practice.

3) Tree Tenders Training Program, LEAF
Already providing a successful training program for resident volunteers, LEAF (Local Enhancement and Appreciation of Forests) proposes to continue and improve delivery of this program, expanding from Toronto into York Region. Through further development of this model education program, replication in other communities will be possible. The Tree Tenders training course involves classroom instruction as well as outdoor, hands-on activities to provide citizens interested in improving the urban forest with basic arboricultural training (instructors are ISA certified arborists).
