Summary: This licence has been issued for the scientific research application No.5263. The aim is to monitor vegetation changes in current climate warming for simulating past and future dynamics with an individual-based spatially explicit model. Therefore, the intentions are: 1) assessing stand inventories at diverse bioclimatic and environmental settings by a space-for-time approach; 2) gathering remot...

Summary: The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems and the impact of climate change on tree growth in the Mackenzie Delta. Lake s...

Summary: 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. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...

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...

Summary: The 2005 terrestrial studies include vegetation mapping, rare plant surveys, rare plant mitigation planning, timber cruising, and landform, soil and permafrost investigations. All of the studies will be conducted by three- or four-person crews supported by helicopter. A local assistant will be included as part of each terrestrial survey team to assist in observing and recording data taken at surve...

Summary: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The main objectives of the 2005 field season are to collect data on the annual growth of fine roots, and to further examine the rate of soil respiration. Both of these...

Licensed Year(s): 2008 2007 2006 2005
Summary: There are three main parts in the researchers' project: 1) investigating changes in vegetation cover in the Inuvik region during the past 10,000 years using fossil pollen and stomata preserved in lake sediment; 2) investigating the importance of disturb...

Principal Investigator: Walker-Larsen, Jennifer
Licensed Year(s): 2003 2002 2001 2000
Summary: Baseline data on the rate at which trees grow (productivity) and the time required for trees to re-establish (regeneration) following fires and human disturbances are required to determine forest sustainability and to understand how habitat changes over...

Licensed Year(s): 1998 1997
Summary: The research team consisting of forest ecologists, will go to Wood Buffalo National Park by air. A rental vehicle will also be used in the field. Most activities will consist of re-measuring jack pine stands that were examined in 1992. Various kinds of measuring tapes and a pole are used to obtain data. A few stands will be studies by taking stem samples for examination of tree rings and tree g...

Principal Investigator: Henry, Greg H. R.
Licensed Year(s): 1995 1994 1993 1991
Summary: The researchers will measure various parts of the trees and take seed samples found on tree islands. They will take small cores from the base of the largest stems to determine age and growth rates. The tree rings can show how well the tress were growing in the past, and this can be related to changes in the climate....
