Integrating field data, remote sensing and modeling to better understand the vulnerability of boreal-taiga ecosystems to wildfire
Principal Investigator: Bourgeau-Chavez, Laura L.
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5972. The overall goal of the proposed research is to improve understanding of the controls and impacts of a changing climate on the vulnerability and resiliency of boreal-taiga ecosystems to wildfire. This is being addressed through field sampling and process-based ecological and hydrological modeling of the 2014-2016 wil...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2017 2016 2015 2014 2013 2013
Summary: This licence has been issued for the scientific research application No.5221. The project is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemome...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Summary: This licence has been issued for the scientific research application No.5219. Through this project the research group will address the following objectives: What is the net effect of permafrost thawing induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported decrease...


Post-fire forest regeneration in the Western Canadian continental boreal forest: measurement and landscape modeling
Principal Investigator: Gal, Ruth A.C.
Licensed Year(s): 2005
Summary: The objective of this study is to develop a landscape model capable of predicting regeneration after fire in the Northern Boreal Forest. Data has been collected in the past from Porter Lake (near Lutsel K'e), Big Fish Lake, Alberta, and Wood Buffalo National Park, between Pine Lake and Peace Point. Data has also been collected from the International Crown Fire Modeling Experiment near Fort Pro...


Post-fire decomposition of woody material and post-fire habitat structures in the western Canadian boreal forest.
Principal Investigator: Sander, Barbara
Licensed Year(s): 1997
Summary: Burned areas of different ages have been identified from fire-history maps and data bases provided by the Forest Management Division of the NWT in Fort Smith. Chosen fires are located along the Highways 1, 2 and 5. Access and transportation will therefore be by car/truck. The exact location of the sites will be documented by using GPS-equipment. A total of three sites (Jack Pine, Black Spruce ...


Modelling the establishment and growth of post-fire tree seedlings
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...


Biomass estimation for North American Boreal Forests: The first step toward statistically valid global measures.
Principal Investigator: Simpson, Lloyd G.
Licensed Year(s): 1988 1987
Summary: To obtain the first statistically valid estimate of the biomass of the North American boreal forest. To locate sample plots that are randomly located throughout the boreal forest and make simple non-destructive dimensional measurements of trees and shrubs....
