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...

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...

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...

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...

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...

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...

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...

Summary: The primary objective is to quantify the relationships between vegetation community composition and structure and near-surface ground ice content. An improved understanding of ground ice-vegetation interactions could contribute both to the understanding of permafrost ecosystems as well as the more applied geotechnical value afforded by an easily measured surrogate of near surface ground ice condit...
