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...

Principal Investigator: Green, Scott
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....

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...

Principal Investigator: Osawa, Akira
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....

Principal Investigator: Gal, Ruth Ann
Licensed Year(s): 1993 1992
Summary: As a result of global warming (which results from increased amounts of carbon dioxide in the atmosphere), it is suggested that the number of forest fires and the amount of area burned may increase in the northern boreal forests. The types of trees that grow first in these burned areas may be different from those that would have grown in if the climate was cooler. I will collect data at burn site...

Principal Investigator: Wein, Ross
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: 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....
