The University of Vermont will host the 8th Eastern CANUSA conference in forest science from September 30th to October 1st, 2016. The theme for this year's gathering is "Understanding and Managing ECANUSA Forests in a Changing Environment". Currently, many stressors and agents of change are converging on the region’s forests and we are inviting scientists and practitioners from a large spectrum of expertise to address the challenges this presents.

As in past years, the conference will include a full day of plenary and concurrent oral presentations, a poster session and a half day field tour. Friday evening will also include a reception, dinner banquet and a keynote speaker. As always, ECANUSA is open to all forest science fields, including the following:

  • Adaptive Management
  • Decision Support Tools
  • Forest health
  • Forest disturbance ecology and dynamics
  • Abiotic disturbance
  • Human dimensions
  • Community based forestry
  • Family forest owners
  • Land use and fragmentation
  • Silviculture
  • Managing forested ecosystems
  • Forest policy and economics
  • Forest ecology and wildlife

And all other subjects related to the forests of eastern North America.

Field Trip Descriptions

  • Jericho Research Forest – Jericho Vermont:
  • B3F3 Restoration chestnut demonstration planting (Ralph Tursini, UVM): As climate warms, species at the northern edge of their geographic range are predicted to expand northward. In the northeast this will likely include oak/hickory forests, with a strong potential for restoration of the once dominant American chestnut. At the Jericho Research Forest, B3F3 blight resistant American chestnut seedlings were planted to determine the impact of silviculture on tree growth, phenology and cold damage (winter shoot and spring leaf frost injury) at the species’ northern range limit.
    Larch Management (Justin Waskiewicz, UVM): In 1941 two 5-hectare old field blocks were planted with Japanese and European larch, exceeding all other plantations in growth over subsequent years. Over the decades, the stands have been managed to inform sawtimber volume and prescribed fire management. In 2007 a partial harvest was conducted to encourage transition to uneven aged northern hardwoods. Both the 2007 and more recent 2014 harvest serve as examples of the UVM Green Forestry model, balancing management objectives, financial return while paying contractors well for high quality work.
  • Proctor Maple Research Center – Underhill Vermont
  • Sugarbush Research and Management (Mark Isselhardt, UVM): The University of Vermont Proctor Maple Research Center has engaged in basic and applied research related to the physiology of maple trees and the production of pure maple syrup for 70 years. The 220 acre property includes a demonstration sugarhouse that produces over 2,000 gallons of syrup annually. Recent research has focused on strategies for efficiently maintaining high sap yields, exploring how modern production methods impact the chemistry and flavor of syrup as well as investigating the long term sustainability of this iconic product.
    Sugar Maple Phenology and Climate Change (Joshua Halman and Sandy Wilmot, VT FPR): Annual changes in the timing and duration of bud and leaf development are important to understanding the interactions between environmental stresses and forest ecosystems. Subtle changes in tree phenology may be an early indication of larger changes to be manifest in the future. At the PMRC, state forest health specialists have been monitoring sugar maple phenology each year since 1991. Assessments of both spring and fall phenology show significant trends over time.
