Impacts of permafrost thaw on land cover and downstream water quality
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5568. The primary objective of this project is to link long-term records of ground temperature and permafrost conditions with changes in landcover and water quality of adjacent ponds and lakes. In other words, how thawing permafrost alters terrestrial and aquatic ecosystem properties. Along the Mackenzie Valley corridor...


Tundra shrub response to climate change-exacerbated disturbances
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5567. This project has two primary objectives: 1) To investigate the differences in shrub productivity traits between undisturbed and disturbed tundra sites to better understand the impact of shrub expansion and disturbance on ecosystem function. 2) To investigate the impact of shrub productivity trait differences on deco...


Impact of wildfire and forest management on permafrost and post-fire regeneration
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2024 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5223. This projects two main objectives are to monitor the recovery of NWT forests following wildfire to better understand post-fire changes on forest composition and ground vegetation and to develop baseline information about proposed forest management areas to support assessment of harvesting impacts on these areas. T...


Impacts of wildfire extent and severity on caribou habitat
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2018 2017 2016
Summary: The main objective of this fieldwork is to support the collection of data for predictive caribou habitat mapping within the forested areas of the Taiga Plains and Taiga Shield Ecoregions in NWT, roughly south of Great Bear Lake. The research team will complete the establishment of a network of long-term study plots across a range of fire characteristics and vegetation types, where the team will me...


Drivers and consequences of shrub distribution on the tundra landscape
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2017 2016
Summary: The objective is to determine the growth and recruitment responses of trees and shrubs to changing climate conditions near tree line and improve the understanding of the drivers of shrub patch expansion on the tundra. Ten shrub patches were selected for measurement and paired permanent monitoring plots were established at each patch; one plot was centred on the patch of interest, the other on t...
