Using controlled water treatment on understory plant species to determine the effects of climate change on the boreal forest
(2018)
Climate change poses a big threat to boreal forest managers. We have set out to test how different precipitation levels will affect a number of boreal understory species across the three forest types commonly found in the ...
The Root dynamics of mixed and single species stands in the boreal forest of central and eastern Canada
(2010)
I examined trends of fine root biomass and necromass in different mixed- and single-species stands within the central and eastern regions of the North American boreal forest to determine how annual fine root production, ...
Assessment of black spruce portfolio trial survival and growth and implications for reforestation under climate change
(2018)
The purpose of this study is to assess the performance of black spruce seedlings
at a genetic trial designed to select seed sources adapted to several climate change
scenarios. Height variability among trees is attributed ...
Biodiversity of ground beetles in young and old poplar stands
(2019)
Ground beetles (Coleoptera: Carabidae) are a useful bioindicator group in forests in almost every part of the world. This thesis studied the biodiversity of carabid beetles in old and young age trembling aspen (Populus ...
Well-spaced and free-growing: effects and interactions of ecosite and renewal treatments on regenerating stands in northwestern Ontario
(2019)
Effective renewal of harvested stands in Ontario is mandated in the Crown Forest Sustainability Act (CFSA 1994). Properly prescribed silviculture leads to forested stands that are regenerated successfully, have predictable ...
Effects of species mixtures on fine root production in a young boreal forest
(2019)
1. Fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. Species diversity
loss has been recognized as one of the primary global change drivers that can have
profound negative effects on ecosystem ...
Global environmental change effects on forest dynamics: lessons from permanent sample plot networks
(2019)
Global environmental change caused by anthropogenic emissions of greenhouse gasses is a major threat to forest ecosystems globally. Before we can begin to adequately mitigate these threats, we first must understand how ...
Comparing the spatial pattern of fire and harvest disturbance in boreal Ontario watersheds
(2016)
Fire and harvest are both major sources of disturbance in Ontario’s boreal forest.
They are largely responsible for successional patterns in forest vegetation, and influence
regimes of hydrologic change in boreal streams, ...
Classification of red pine stands using remote sensing techniques
(2019)
Red pine is a historically important species for forestry in the boreal forest. Its large diameter and straight and knot free form has made it ideal for many purposes, including construction. With the new sudden turn towards ...
