Drivers and consequences of shrub distribution on the tundra landscape
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 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 our understanding of the drivers of shrub patch expansion on the tundra. Understanding the drivers of shrub distribution and shrub patch expansion on the tundra: Ten shrub patches were selected for measurement and paired permanent monitoring plots wer...


Impacts of wildfire extent and severity on caribou habitat
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2016
Summary: The objective is to improve the empirical foundations 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. A network of long-term study plots will be established across a range of fire characteristics and vegetation types, where the research team will measure the rate and direction of forest and c...


Responses of trees and shrubs to climate warming at high latitudes
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2015 2014
Summary: To determine the growth and recruitment responses of trees and shrubs to changing climate conditions the near tree line. The research team will measure long-term tree and shrub growth at Havikpak and Trail Valley Creek using tree ring analysis. Specifically, at each site, small wood samples (cores) will be taken from each individual to measure the changes in annual ring widths through time. Wit...


Ground ice - vegetation relationships in the North Slave region
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2015 2014
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...
