Impact of permafrost thaw and wildfire on carbon storage in peatlands
Principal Investigator: Turetsky, Merritt R.
Licenced Year(s): 2014 2013
Summary: The research team aims to study if permafrost thaw in peatlands is linked to rapid losses of organic matter. The field work will focus on extracting a number of cores from different peatland sites that differ in their permafrost status and in fire history. By examining the peat layers in the core the team will be able to reconstruct the history of the site and to link changes in permafrost conditi...


Impacts from climate change on berry productivity in the Canadian Arctic: Integrating community participation with science
Principal Investigator: Desrosiers, Sarah CE
Licenced Year(s): 2013 2012
Summary: The main objective of the Berry Project is to establish a long-term community-based monitoring program in arctic communities using culturally important berry species as indicators of climate change. The project’s main objectives for the Daring Lake Tundra Science Camp are to bring awareness to the effects of climate change and to expand environmental stewardship. These goals can be achieved by del...


Northern Native Seed Development Field Trials
Principal Investigator: Trimble, Annika EV
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2007 2006
Summary: The objective of this sub-project is to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007. The investigator intends to collect data regarding winter survival, seedling emergence, and overall plant vigour and productivity in order to assess each species' and collection's suitability for use in land reclamation in the NWT. Th...


Northern Native Plant Development Collections in the NWT
Principal Investigator: Seccombe-Hett, Pippa
Licenced Year(s): 2007 2006
Summary: This project has been designed in order to develop technologies utilized to propagate and cultivate native plant species. The main deliverable will ultimately provide a system where-by these species will become available for commercial production and use in revegetation and reclamation in the Northwest Territories. The need for native plant seed for reclamation and restoration has been identified ...


Environmental Studies for the Proposed Parsons Lake Development Area During Summer 2007 – Vegetation Studies
Principal Investigator: Graf, Linda H
Licenced Year(s): 2007 2006
Summary: The objective of the vegetation study is to continue to record baseline information on lichen health and productivity which may then be used to monitor impacts as a result of construction and operation activities in the proposed Parsons Lake development area. These studies are a continuation of those conducted previously in summer and fall of 2006. The study will link to caribou monito...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: With climate change it is important to examine the current condition of permafrost. The research aims to measure how much it is changing by each year, and measure the temperature of the permafrost year-round. The project also aims to measure the rate of plant recovery on the disturbed areas. Intensive investigations were carried out in 1974, 1977 to 1982, and ever since 1990, when automated microc...


Post Construction Revegetation and Permafrost Monitoring within Paramount's Cameron Hills, NWT Project Area
Principal Investigator: Ferguson, Gordon
Licenced Year(s): 2003
Summary: Following environmental impact assessments, the National Energy Board and the Mackenzie Valley Land and Water Board granted approvals to Paramount Resources Ltd. for the construction of specific infrastructure within the Significant Discovery Area. Atta...


Canadian Arctic Plants: Systematics, Evolution and Floristics
Principal Investigator: Gillespie, Lynn J.
Licenced Year(s): 2003 2000
Summary: This research will study variation among arctic plants (bluegrasses, alkali grasses, arctic poppies, arctic mustards) to better define species so that arctic plants may be more easily identified, and to better understand the origin and evolutionary relat...


Distribution of Dark-Celled Fungal Root Endophytes Along an Arctic to Boreal Latitudinal Gradient
Principal Investigator: Piercey, Melissa
Licenced Year(s): 2000
Summary: Roots of plants inhabiting cold-stressed environments are often colonized by vegetatively reproducing fungi. The researcher will examine the genetic variation within and among populations of Phialocephala fortinii P. along a latitudinal gradient encompassing the boreal, subarctic and arctic zones in Northern Canada. The researcher will travel from Yellowknife to 3 study sites surrounding Great ...


Forestry Research in the Gwich'in Settlement Area
Principal Investigator: Walker-Larsen, Jennifer
Licenced Year(s): 2003 2002 2001 2000
Summary: Forest Fire Effects on Vegetation and Wildlife Habitat use: Research sites will be accessed by helicopter. Sites are located in burns of different ages. In the summer, small teams will complete vegetation plots, assess species composition and percent cover, and assess wildlife abundance. In the winter, helicopter track surveys will be completed. Forest Monitoring (ARNEWS and SI/MAB plots): The...
