Principal Investigator: Williams, Christopher J
Licensed Year(s): 2005 2003
Summary: The objective of this project is to make detailed measurements of fossil plants that grew at high latitudes between 12 and 2 million years ago. The researchers will use these and previously obtained data to test the hypothesis that until about 28 million years ago arctic wetland forests were high biomass forests dominated by deciduous conifers, but by 12 million years aga, these were replaced by ...

Principal Investigator: Osawa, Akira
Licensed Year(s): 1994
Summary: The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

Licensed Year(s): 1995 1994 1993 1991
Summary: This study continues from the research conducted in 1991 where we examined the plant community and assessed plant distribution as the subarctic forest changes to tundra. We are interested in how the smaller plant species are influenced by changes in the number of trees that are nearby as well as changes in climate. Permanent plots will be established in order to monitor any changes in the plant ...

Summary: Tree-line plant species are sensitive to changes in climate. Most trees growing in the tree-line reproduce by `layering' which means that they do not produce seeds but instead the tree limbs of individual trees produce roots to generate another `tree'. Seeds can only be produced when the summer climate is warm enough. By monitor- ing the reproduction of trees in the tree-line, information can be...

Licensed 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...

Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher and his team will seed and plant plots prepared in 1990. They will determine the germination rate, establishment and the annual growth of the seedlings. The measurements will be related to the energy input which influences these microsites....

Principal Investigator: Eggertsson, Olafur
Licensed Year(s): 1990
Summary: The Researcher will sample about 100-200 driftwood logs using a chain-saw to cut off a 1-2 cm plate about 0.5 m inside the end of each log. The material will be shipped to Lund University laboratory for examination....

Principal Investigator: Greene, David F
Licensed Year(s): 1982
Summary: To undertake a study of white spruce, genus (Picea glauca). i) digging of seedlings ii) coring of mature trees iii) digging 3 soil pits iv) collecting plant samples v) collecting seed samples vi) felling approx. 15 trees (all sizes - one location) This is the field work in conjunction with an MSc. thesis....

Principal Investigator: Suzuki, T..
Licensed Year(s): 1977
Summary: To measure a number of sample forest plots in detail to assemble a body of data with which to test a computer simulation model of the growth and development of tree stands....
