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...

Northern Water Futures Baseline Environmental Monitoring
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2021 2019 2018
Summary: The overall objective is to understand existing and potential impacts of climate change and resource development in the Sahtú region on four key aspects: 1) the landscape, 2) vegetation, 3) water resources, and 4) aquatic ecosystems. Specifically, the research team seek to understand: a) terrain instability due to permafrost thaw, especially around communities and culturally-important areas; b) ve...

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...

Responses of trees and shrubs to climate warming at high latitudes
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2015 2014
Summary: The objective of this project is to determine the growth and recruitment responses of trees and shrubs to changing climate conditions near tree line and to study drivers of shrub expansion on the tundra. To accomplish these objectives, researchers will measure long-term tree and shrub growth at Havikpak and Trail Valley Creek using tree/shrub ring analysis. Specifically, at each site, small wo...
