Research Interests and Areas of Expertise: My research interests are in the general areas of Geographic Information Systems and cartography, and the application of this technology to land management and resource assessment. Current projects monitoring landscape diversity and change in the Sierra de Manantlan Biosphere Reserve, Mexico; modelling land use change and forest fragmentation along sections of the Niagara Escarpment, Ontario, and assessing the spatial dimensions of land use conflict in the Tianmushan Biosphere Reserve, China. Other research initiatives focus more specifically upon map communication, graphic design, and cartographic symbolization. Recent completed work has evaluated the thematic mapping capabilities of PC-based GIS software and the development of guidelines to improve these capabilities, and the use of illustration software for enhancing GIS map output, and the use of the Internet in GIS instruction.
Current Research Projects:
- Modelling Landscape Diversity and Change in the Sierra de Manantlan Biosphere Reserve, Mexico, This study applies techniques for spatial modelling and change detection, based on geographic information systems and digital image processing methods, to aid the effective and sustainable management of land in the Sierra de Manantlan Biosphere reserve in southwestern Mexico. The project involves researchers at the Universities of Guelph, Wisconsin, and Guadalajara, and provides exchange opportunities for students from all three institutions.
- Change in Land Use/Land Cover Patterns in the Credit Valley Area of the Niagara Escarpment: This study evaluates the spatial and temporal dimensions of landscape change along the Niagara Escarpment. Work focused initially on examining the changes in forest cover and fragmentation in the forks of the Credit area between 1977 and 1996. Efforts are now underway to extend this work to the entire Credit River Watershed, with involvement of researchers from Credit Valley Conservation.
- Assessing the Spatial Dimensions of Land Use Conflict in the Tianmushan Biosphere Reserve, China: Protected natural areas in the Tianmushan Biosphere Reserve include magnificent stands of ancient ginkgos, chinese cedars, and golden larch. This small Reserve also supports a Buddhist community and temple, a growing complex of tourist facilities, and local residents engaged in agriculture and the harvesting of forest products. Balancing these various land use needs is an on-going challenge, and provides an opportunity to assess the use of GIS-based land allocation models in land management decision-making.
