Dr. Jennifer Baltzer is a Canada Research Chair in Forests and Global Change at Wilfrid Laurier University, whose work focuses on the drivers of forest composition, structure and function and responses of these systems to global change. She has worked in a range of systems from the tropics to the tundra but currently leads an extensive boreal forest research program throughout the Northwest Territories. Her interdisciplinary research program examines the impacts of climate warming, including permafrost thaw, wildfire regimes, and biome shifts, on the distribution and function of high latitude boreal forests and its implications for northern communities.

Dr. Baltzer works closely with the Government of the Northwest Territories (GNWT) through a 20-year Partnership Agreement between the GNWT and Laurier. Dr. Baltzer plays leadership roles in NASA’s ABoVE campaign, the Smithsonian Institute’s ForestGEO Network, and the CFREF-funded Global Water Futures program. In 2017, Dr. Baltzer was elected to the Royal Society of Canada’s College of New Scholars, Artists and Scientists. Recently, Dr. Baltzer was named Laurier’s 2020 University Research Professor.

Postdocs

Raquel Alfaro Sanchez

Raquel is interested in how forest ecosystems, from Mediterranean, tropical and boreal regions, respond to the unprecedented increase in frequency and intensity of wildfires and climate extremes. Much of her research is focus on the use of tree-ring records to understand the response of growth, climate sensitivity and functional traits of trees to climate change hazards to ultimately provide direct management implications for both, risk mitigation and post-hazard recovery.

Maria Belke Brea

Maria’s research focuses on plant-environment interactions and more specifically on environmental disturbances and the subsequent plant recovery in the boreal forest. As a postdoctoral fellow in the Forest Ecology Research Group, she will apply spectral analysis on remote sensing data from drones, airplanes and satellites to create large-scale vegetation and plant recovery maps.

Caitlyn Lyons

Caitlyn is interested in how nutrient release from thawing permafrost is impacting the boreal forest in the Northwest Territories. More specifically, she is focused on the ability of boreal trees to acquire and use these novel nutrients.

NiaPerron

Nia Perron

Nia’s research interests lie in gaining a better understanding of plant physiological water use. More specifically, she is interested in patterns of water storage and transpiration in trees growing across Canada’s western Boreal forest and the environmental variables that alter these water-use patterns.

Katherine Standen

Katherine’s research interests involve responses of plants to large scale disturbance. Specifically, Katherine is researching changes in plant community composition, structure, and function in response to permafrost thaw with a focus on how these changes may influence carbon cycling in boreal peatlands

MsC STUDENTS

JocelynBiro

Jocelyn Biro

Jocelyn is studying patterns of moose forage recovery following fire and how this is modified by post-fire forest management decisions in British Columbia. Moose populations are declining in some parts of the province and this will help us understand whether forage availability is contributing to this decline.

Alexis Jorgensen

Alexis is studying plant recovery in the boreal forest after fire and how this influences wildlife such as moose, caribou, and bison. She is also very interested in reconciliation and, though Covid-19 travel restrictions have cancelled her plans for a more direct working relationship, will be sharing her results and accepting feedback from a NWT community within her study area.

Emily Ogden

Emily is studying the role of changing permafrost conditions on boreal forest productivity. Working in partnership with the Geological Survey of Canada, Emily is using a long-term ground temperature dataset to try to better understand variability in forest productivity changes over the last 30 years.

NORTHERN WATER FUTURES

Cory Savage

Cory Savage

Cory completed her MSc in Biology at the University of Waterloo, during which she researched contaminants in lakes downstream of oil sands activities in northern Alberta. As the Project Coordinator for Northern Water Futures, Cory is interested in supporting interdisciplinary northern research through the management of daily project operations and execution of broader organizational goals.
