Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: The objectives of the 2015 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 ...


Structure of black spruce forests on continuous permafrost
Principal Investigator: Osawa, Akira
Licenced Year(s): 2005
Summary: The researchers will measure black spruce forests along the Dempster Highway. They will determine if the trees can only grow to a certain limit that cannot be surpassed, regardless of the number of trees per hectare. A limit of this kind was recently discovered in Siberia. The number of trees per hectare and above-ground biomass will be estimated in numerous black spruce stands. A method ...


Analysis of Natural Thinning Processes in Mixed Species Forests.
Principal Investigator: Osawa, Akira
Licenced Year(s): 2000
Summary: The main objective of the proposed research is to collect extensive data of tree size and stand density from mixed forests of Jack pine and quaking aspen in Wood Buffalo National Park and to examine theoretically the patterns of quantitative forest development with special reference to the phenomenon of 'natural thinning' in even-aged forests. The research team consisting of forest ecologists will...


An Exploratory Evaluation of the Effect of the Climate Change During the Past Two Centuries on Structure of Jack Pine Forests.
Principal Investigator: Osawa, Akira
Licenced Year(s): 1999
Summary: The main objective of the proposed research is to reconstruct the structure of monospecific forests of different ages, and to explore whether or not the recent climate change has affected the structure of the forests in northern Canada. Pure stands of Jack pine or aspen will be studied in Wood Buffalo National Park. The intent is to determine the effect of the so-called Climate Change on those f...


Reconstruction of Forest Structure and function in Canadian Taiga
Principal Investigator: Osawa, Akira
Licenced Year(s): 1998 1997
Summary: The research team will consist of forest ecologists. We plan to study a few jack pine stands by taking stem samples for examination of forest growth that occurred in the past. A possible effect of climate change on the growth of forests are being examined. Several trees were cut and were analyzed last year. This summer several additional stems will be sampled. When a tree is cut, we try not to dis...


Jack Pine Forest Research
Principal Investigator: Osawa, Akira
Licenced 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....


Testing the Allometric Theory of the Self-Thinning Rule
Principal Investigator: Osawa, Akira
Licenced Year(s): 1992 1991 1987
Summary: The researcher and his team will estimate the number of trees and monitor individual growth in flagged and tagged stands, as well as estimating foliage weight of individual trees. They will measure light conditions in various jack pine stands, as well as collect stem cores to be analyzed and compared with stem cores from other parts of the northern hemisphere for the possibility of accelerated gr...
