Monitoring forest structure and treeline change drivers
chercheur principal:
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5263. The aim is to monitor vegetation changes in current climate warming for simulating past and future dynamics with an individual-based spatially explicit model. Therefore, the intentions are: 1) assessing stand inventories at diverse bioclimatic and environmental settings by a space-for-time approach; 2) gathering remot...

Effects of permafrost thaw on soil processes and soil-plant interactions
chercheur principal:
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5246. The main goal of the project is to understand which mechanisms are controlling soil nutrient cycling and soil-plant interactions across both permafrost thaw gradients and vegetation types. The research team are mainly interested in nutrient cycling processes and priming, as well as how microbial community composition ...

Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2007 2006
Résumé: The objective of this sub-project is to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007. The research team intends to collect data regarding winter survival, seedling emergence, and overall plant vigour and productivity in order to assess each species' and collection's suitability for use in land reclamation in the NWT. T...

Tree Regeneration on Seismic Lines
chercheur principal:
Année(s) de permis: 2005 2004
Résumé: The purpose of this three-year project is to identify the factors that promote or retard forest regrowth after seismic line cutting. Oil and gas development in the Mackenzie Valley has the potential to heavily impact the region's slow-growing forests....

Dispersal of white spruce seeds and pollen/understory scarification in a mast year
chercheur principal:
Année(s) de permis: 2002
Résumé: The long distance dispersal of tree pollen and seeds is of considerable interest as we ask how fast plants can migrate in response to rapid climate change. Examination of seed dispersal will actually be based on looking at germinants (rather than seeds)...

Forestry Research Projects in the Gwich'in Settlement Area: Seismic Line Revegetation in the Gwich'in Settlement Area (GSA)
chercheur principal:
Année(s) de permis: 2003 2002 2001 2000
Résumé: Baseline data on the rate of tree growth (productivity) and time required for trees to re-establish (regeneration) following fires and anthropogenic disturbances are required to determine forest sustainability and understand how habitat changes over time...

Re-evaluation of Disturbance Experiments in the Lower Mackenzie Region, NWT
chercheur principal:
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: In the early 1970's, several test plots were established to see what happens when the plants and soil are disturbed or removed by fire, oil spills, and vehicles. Dr. Wein and two students will be re-visiting these sites to document how the plants have recovered since that time....
