Principal Investigator:Osawa, Akira Licenced Year(s):
Objectives of the field work are two-fold: one is to collect data in jack pine and in lesser extent black spruce forests on annual movement of organic matter and carbon; the other is to continue the study of stand development and its relationship to environmental factors (a discipline called ‘silvichronology’). For the former objective, the research team will continue measurement of the growth of ...
Principal Investigator:Pichler, Viliam Licenced Year(s):
The objective of this study is to determine soil organic carbon quantity and quality under open stands of Picea glauca and Picea mariana close to northern forest limits as opposed to open tundra. To enable predictions of forest propagation on soil carbon dynamics under extreme climate conditions.
Taking samples from the soil and trees in the Richardson Mts., specifically at two points with the...

The objective of this project is to continue with phytoremediation planting on the Nota Creek C-17 well site. More impacted soil has been integrated into the phytoremediation process and additional plantings are necessary to determine the efficiency of the phytoremediation program and to further validate it as a remediation strategy for the well site.
Planting is planned for late June, site mo...
Principal Investigator:Turetsky, Merritt R. Licenced Year(s):
The objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning.
Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...
Principal Investigator:Walker, Xanthe J Licenced Year(s):
The overall objective of this research is to determine the impact of climate change on the ecological patterns and processes of white spruce trees within the forest-tundra transition zone in the Tuktoyaktuk region of the Northwest Territories, Canada. White spruce reproduction, establishment, and growth will be assessed to determine how these parameters may have changed since they were last measur...

This licence is being issued for the scientific research application No.1089.
The overarching goal of this research is to understand the effects of temperature and moisture variability on growth of forest vegetation in the southern Arctic, and to use the relationship between temperature/moisture and tree growth to construct a model of patterns of greening and browning in the forest and forest-t...

This licence is being issued for the scientific research application No.1103.
The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape.
Specific research questions are:
1. How often for...
Principal Investigator:Greene, David F Licenced Year(s):
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...

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....
Principal Investigator:Johnston-Schuetz, Cheryl Licenced Year(s):
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 ...
