Changing beaver distribution and occupancy in north-west Canada
Principal Investigator: Wheeler, Helen
Licensed Year(s): 2023 2022 2021 2020
Summary: This licence has been issued for the scientific research application No. 5634. Objectives: 1, To monitor beaver occurrence changes; 2, To assess past beaver occupancy patterns using shrub ring analysis; and, 3, To understand how permanent and transient beaver populations impact their environment. Activities: 1. Conduct canoe and boat-based visual surveys to map beaver distribution in the...


A 2,000 year record of climate change from white spruce tree-rings
Principal Investigator: Porter, Trevor
Licensed Year(s): 2019
Summary: This fieldwork aims to collect ‘disk’ samples from dead trees found on the surface or partially buried in sediments. Previous research in the Campbell Dolomite Upland area reported deadwood samples dating back to AD 1060. This area is well-drained, which is the ideal environment for preserving deadwood over long periods. The research team will return to this area to search for older specimens dati...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: Objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the patter...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licensed Year(s): 2017 2005 2004 2003 2002 2001
Summary: The objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the pa...


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...


Landscape scale flooding in the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...


Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2008 2007 2006 2005
Summary: The objective of this research is to study the impacts of climate change on boreal and aquatic ecosystems in the Mackenzie Delta region. By doing so, the researchers hope to gain a better understanding of the effects of long-term climate change on these ecosystems. Their study will utilize dendrochronological and paleolimnological methods to examine spruce forests and lake sites situated in the in...


The relation between climate and abundance cycles in barrenland caribou herds, NWT.
Principal Investigator: Zalatan, Rebecca
Licensed Year(s): 2005
Summary: Caribou populations fluctuate over long time spans. However, long-term records of population cycles are scarce. Dendrochronology and hoof scars left on the surficial roots of spruce trees across caribou trails will be used to reconstruct the population...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2002
Summary: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...


Dendrochronology of Arctic Driftwood
Principal Investigator: Eggertsson, Olafur
Licensed Year(s): 1990
Summary: The Researcher will sample about 100-200 driftwood logs using a chain-saw to cut off a 1-2 cm plate about 0.5 m inside the end of each log. The material will be shipped to Lund University laboratory for examination....
