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 ...
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 ...
A script for the automatic delineation of canopy gaps from raster images and incorporation of analysis with Ontario’s FRI datasets
(2019)
This thesis project serves as a tool for resource managers looking to delineate gaps in the forest canopy, where a Canopy Height Model raster is available. Once identified, analysis is performed in order to assess the ...
Lichen detectability under varying canopy closure
(2019)
Monitoring lichen distribution is of increasing concern as mapping is critical in characterizing habitat for woodland caribou. Aerial photography collected using drones, the method used for this study, is a common method ...
Does Canada lynx trapper harvest track population cycles? A review of data from 1973 to 2016 in Ontario's sixteen northern forest districts
(2019)
The Canada lynx (Lynx canadensis) has been widely studied for its strong
interaction with the snowshoe hare (Lepus americanus), and the lynx exhibits a slightly
lagged, 10-year population cycle dependent on the hare ...
