Changes to plant communities in the Northwest Territories, Canada
Principal Investigator: Singer, Claire L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5608. Objectives: To investigate the relative invasibility of different regrowth stand types post-fire; and, To complete river surveys of invasive plants downstream of Hay River and Fort Liard. Burns: To assess the invasibility of different regrowth stand types, samples will be taken along transects running perpend...


Climate and human-mediated range shifts of plants in the NWT, Canada, and impacts to native plant and soil communities
Principal Investigator: Singer, Claire L
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5272. The proposed research aims to measure the extent of non-native plant spread into natural areas in the NWT, assess the impact of this spread to native plant and soil communities, and assess the risk of invasion from plants in neighbouring jurisdictions. Sampling plots at increasing distances from the roadside or ri...


Sanguez Lake Fish Down Study
Principal Investigator: Low, Mike
Licensed Year(s): 2021 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4844. The objectives of this study are to: 1) establish a population estimate of walleye in Sanguez Lake; 2) establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3) reduce the n...


Hay River Transboundary Fish Sampling
Principal Investigator: Levasseur, Annie
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4830. Residents of Alberta and NWT communities along Transboundary rivers have voiced concerns such as “are the fish safe to eat?” and “are the fish healthy?” due to the potential cumulative effects of multiple substances, habitat alteration and climate change. There is not any significant historical fish sampling relating ...


Horn River Creel Survey and Stock Study
Principal Investigator: Low, George
Licensed Year(s): 2018 2017
Summary: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...


Enhancement and monitoring of arctic grayling spawning habitat at Providence Creek, NWT
Principal Investigator: Low, George
Licensed Year(s): 2016 2015 2014
Summary: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...


Sahtú Region Caribou and Moose Study
Principal Investigator: Simmons, Deborah L
Licensed Year(s): 2016 2015 2014 2013
Summary: The main objective of this project is to support the wildlife management initiatives proposed by the Renewable Resource Councils (RRCs) in the Sahtú Region through the development of a robust research program that incorporates multiple sources of knowledge into a detailed understanding of caribou and moose populations. The objectives are to monitor caribou and moose health and understand populatio...


Landscape scale flooding in the Great Slave Lake Plain: Expansion of lakes, flooding of wetlands and implications for bison habitat and local land users (Traditional knowledge study component)
Principal Investigator: Wesche, Sonia D
Licensed Year(s): 2012
Summary: The over-arching objectives of the project are to draw together multiple sources of information to (1) examine the change in lake area in this eco region, (2) quantify the type and amount of habitat loss or modification; (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change; (4) document local and traditional knowledge of physical and biologi...


Exfiltration Fence Habitat Assessment
Principal Investigator: Wilcockson, John B
Licensed Year(s): 2011
Summary: The objective of this research project is to determine the presence or absence of fish species as part of a habitat assessment of the proposed location for an exfiltration trench (effluent diffuser). Collected fish will be identified, weighted and measured. Electrofishing would be conducted along the banks of a 200m stretch of Prairie Creek, at the Prairie Creek mine site. Electro fishing would...


Effects of wildfire on biomass combustion in boreal peatlands and forests
Principal Investigator: Turetsky, Merritt R.
Licensed Year(s): 2011
Summary: The objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning. Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...
