Job/Research Area: Forest Land Reclamation and Applied Forest Ecology


Major Responsibilities/Research Interests

My research addresses questions related to the reclamation of disturbed lands to self-sustaining boreal forest ecosystems common to the boreal forest region. The research program focuses on the function and underlying processes of forest canopy cover as a prime factor in determining forest successional pathways. Key research activities are the development of innovative strategies and techniques for the re-establishment of forests on surface mined lands and determining whether these forests develop and display processes and functions comparable to natural ecosystems. Currently the research focuses on the establishment of trembling aspen (an early successional fast-growing tree species native to the boreal forest) and its use as a nurse crop for forest development. Other active research and research interests are: ecophysiology (growth, photosynthesis, water relations, and carbon allocation) of boreal forest species in response to different abiotic and biotic factors, the effects of forest practices on aspen regeneration and boreal forest vegetation management, and the role of disturbance on forest establishment and tree species distribution.


REN R 120 - Introduction to Plant Identification

Introduction to the classification, identification, distribution, habitat, and ecology of common trees, shrubs and herbaceous species typically found in Alberta and beyond. Lecture and labs emphasize the recognition of identifying characteristics and the use of dichotomous keys to identify about 250 plant species including higher taxa. A self-directed plant collection is mandatory and registered students are encouraged to contact the instructor during the summer months for instructions. Field exercises may take place off campus. This course requires payment of additional student instructional support fees. Refer to the Tuition and Fees page in the University Regulations section of the Calendar.
