Summary: Main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce. Five methods will be used. 1) Soil and air temperature will be measured...

Summary: The research objective is to show that the fertility of black spruce (Picea mariana) in the Arctic is limited by the amount of pollen in the surrounding air. After snowmelt, the researchers will choose unburned black spruce “islands” at different distances from the perimeter of the 1999 Lynx Creek fire. Subsequently, as the developing black spruce pollen cones become easy to see, they will remo...

Licensed Year(s): 2009 2008
Summary: This licence was issued for the application # 836. The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Growth-ring analyses will be conducted in mature treeline populations....

Summary: The objective of this project is to examine the environmental thresholds to the successful establishment of a boreal (high latitude) conifer forest by measuring photosynthetic rates in conifer seedlings. Climate change has the potential to shift southern commercial tree species and treelines northward with implications for existing ecosystems and future economic development. The project’s goal ...

Summary: The objective of this research is to explore the influence of temperature and disturbance on green alder by comparing alder characteristics on sites with different average temperatures and disturbance histories. Understanding of factors that influence alder populations today will assist in predicting the likely consequences of rising temperatures and increased disturbance on tall shrubs. A min...

Summary: The researchers will measure black spruce forests along the Dempster Highway. They will determine if the trees can only grow to a certain limit that cannot be surpassed, regardless of the number of trees per hectare. A limit of this kind was recently discovered in Siberia. The number of trees per hectare and above-ground biomass will be estimated in numerous black spruce stands. A method ...

Summary: The purpose of this three-year project is to identify the factors that promote or retard forest regrowth after seismic line cutting. Oil and gas development in the Mackenzie Valley has the potential to heavily impact the region's slow-growing forests....

Summary: The long distance dispersal of tree pollen and seeds is of considerable interest as we ask how fast plants can migrate in response to rapid climate change. Examination of seed dispersal will actually be based on looking at germinants (rather than seeds)...

Principal Investigator: Van Gerwen-Toyne, Melanie
Licensed Year(s): 2003 2002 2001 2000
Summary: Baseline data on the rate of tree growth (productivity) and time required for trees to re-establish (regeneration) following fires and anthropogenic disturbances are required to determine forest sustainability and understand how habitat changes over time...

Summary: The Gwich'in Renewable Resource Board (GRRB) is working with the Department of Resources, Wildlife and Economic Development (DRWED) and Gwich'in Tribal Council (GTC) to develop a forest management plan for the Gwich'in Settlement Area. In order to manage the forests sustainably, we must have a good understanding of how fast trees grow and how forests regenerate after disturbances (particularly wi...
