Echiverri, Laureen F. I.

For the purpose of informing biodiversity conservation efforts in managed landscapes, we explored whether and how understory plant communities (abundance, diversity, composition) were related to a topographic moisture index, called depth-to-water, in the boreal mixedwood forests of northwestern...

Whitebark pine (Pinus albicaulis) is declining across its range due to disturbances such as mountain pine beetle and white pine blister rust. In this thesis, I assess the response and vulnerability of whitebark pine ecosystems to multiple stressors and disturbances at the northern edge of...

Graham, Erica E.

In the boreal forest of Alberta, Canada, underplanting white spruce (Picea glauca) in aspen (Populus tremuloides) forests attempts to address concerns about "unmixing the mixedwoods". Important ecological differences exist between mixedwood, broadleaf and conifer forests. I studied changes in...

Natural disturbance emulation is being used in forest management in an attempt to mitigate the negative effects of harvesting on biodiversity. In the western Canadian boreal forest where the predominant large-scale natural disturbance is wildfire, harvests that leave live mature trees behind at...

Terrestrial gastropods are important decomposers, herbivores, and prey items in forest systems and constitute a poorly understood element of forest biodiversity in Canada. I studied gastropod assemblages in relation to forest cover type and in response to variable retention harvesting in the...

Pedersen, Jennine L.M.

Given high levels of human disturbance and projected rates of climate change, many species will be unable to keep pace with their shifting climatic ranges and thus face increased risk of extinction. This research investigated the use of assisted migrations for two rare and range-restricted plant...

Understanding the regeneration stage of any species is key to determining the processes that lead to population persistence and structure, community development, and succession. In the case of the endangered whitebark pine (Pinus albicaulis), knowledge of regeneration processes will be important...

Natural disturbances are an integral part of forest ecosystems and drive successional change. The boreal forest is adapted to stand-replacing fires, which have different ecological impacts than less severe disturbances, such as insect attacks. In recent years, mountain pine beetle (MPB), a bark...

Goehing, Jeannine

The effects of different vegetation control practices on tree-weed interactions and associated establishment and early tree growth were investigated in 1-3 year old hybrid poplar plantations containing Walker poplar (Populus deltoides x (P. laurifolia x P. nigra)) and its progeny Okanese poplar...

Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...
