Alternate Forest Products: A Dynamic Time and Space Model of Driftwood Along the Lower Mackenzie River
Principal Investigator: Wein, Ross
Licenced Year(s): 2003 2002 2001
Summary: Currently, the Gwich'in are developing a forest management plan and driftwood is one of the forest products of interest because of rapid community development, piling support requirements, and because the expanding petroleum industry will require large q...


Physical properties of dead and downed round-wood in the boreal forests of Western Canada
Principal Investigator: Wein, Ross
Licenced Year(s): 2002
Summary: Accurate estimates of the bulk density or specific gravity, tilt angle and average diameter of various size classes must be established. This study focuses on collection and validation of these estimates, recognizing that they may indeed change, dependin...


Fire regimes in the western boreal forest and post-fire dynamics of the forest: implications for forest fire management and climate change.
Principal Investigator: Wein, Ross
Licenced Year(s): 1995
Summary: The researchers will sample 200-300 forest stands in Wood Buffalo National Park and surrounding areas as well as in the Fort Simpson area. A number of measurements will be taken in each site as well as soil cores and sections of decomposing logs and snages. These will be taken to the U. of A. for analysis. In addition, sediment cores will be taken in lake sediment and/or peatlands for stratigra...


Forest & Forest Fire Studies in the Mackenzie Delta Ecosystem
Principal Investigator: Wein, Ross
Licenced Year(s): 1994
Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...


Long-term forest-tundra disturbance research
Principal Investigator: Wein, Ross
Licenced Year(s): 1993 1992 1989 1988 1987
Summary: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...


Fire, carbon budget and climate change
Principal Investigator: Wein, Ross
Licenced Year(s): 1993
Summary: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...


Canadian Intersite Decomposition Experiment
Principal Investigator: Wein, Ross
Licenced Year(s): 1993
Summary: Forestry researchers tend to study in detail their local forests yet for major issues such as global warming, it is necessary to conduct research over larger areas to understand impacts on Canadian forests and industry. This study attempts to better describe rates of decomposition and nutrient mineralization across Canadian forests in order to understand how forests are supplied with nutrients fo...


Peat Plateau Collapse and Climate Change
Principal Investigator: Wein, Ross
Licenced Year(s): 1992
Summary: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....


Fire Related Degradation of Palsas
Principal Investigator: Wein, Ross
Licenced Year(s): 1989
Summary: Dr. Wein and his research team are studying permafrost-based wetland forests that were burned by severe fires in 1981....


The Ecological Genetics of Seedling Drought Resistance in Jack Pine
Principal Investigator: Wein, Ross
Licenced Year(s): 1989
Summary: Dr. Wein and his assistant will plant jack pine seedlings in the Reid Lake and Sandy Lake area where the dry conditions simulate a drought. They hope to find a species of jack pine which will survive drought conditions in more southern forests....
