Ms. Shannon Gavin earned a Master’s degree in Conservation Ecology from the University of Calgary (Canada) where her research focused on the effects of linear disturbances on wildlife habitat and behaviour.  She has over ten years of academic and environmental impact assessment experience in wildlife biology with a specialization in human development impacts to wildlife and landscapes.    Ms. Shannon Gavin has provided scientific expertise on a range of projects with Aboriginal communities, regulators and developers in B.C., Alberta and Saskatchewan.  She has extensive experience in project management, technical workshops and providing expert technical reviews for wildlife and biodiversity ranging from small local development projects to large multi-disciplinary third party reviews.

Dr. Brian Kopach
Quantitative and Spatial Ecology

Dr. Brian Kopach is a broadly trained ecologist with over ten years of academic research and resource management experience in ecosystems across western and northern Canada. He has extensive experience designing ecological field studies, and in the collection and analysis of data for both vegetation and wildlife studies. He has led, or assisted with, research and conservation related projects for public and private sector organizations in Canada and the United States, including the Canadian Wildlife Service, the US National Oceanic and Atmospheric Administration, and Ducks Unlimited. Mr. Brian Kopach earned a Master’s degree in Biogeography from the University of Victoria (Canada), and a PhD at the University of Calgary (Canada) examining the ecological and evolutionary consequences of species interactions among alpine plants.


Dr. Sheri Gutsell
Plant Population and Community Ecologist

Dr. Sheri Gutsell is a plant ecologist with interests in plant population and community ecology. She earned a PhD. from the University of Calgary, where her research focused on understanding the mechanisms that drive ecological patterns at individual, population, and community scales. Over the past 17 years, she has worked as a scientific advisor and technical reviewer for various Indigenous communities across Canada on a wide variety of industrial and infrastructure development applications. She has reviewed, advised, and testified at hearings on assessments of project impacts on vegetation components (wetlands, forestry, old-growth forests, rare and sensitive plant species and communities, and plant species of traditional importance) and on cumulative effects, mitigation, monitoring, and reclamation. She also reviews and advises on vegetation, wetland, and reclamation research plans.

Joanne McCallum MSc. P.Chem
Hydrogeochemistry and Hydrogeology

Ms. McCallum is a hydrogeochemist with over 13 years of experience as a Hydrogeochemistry / Hydrogeology consultant in the environmental field, with a focus on aqueous geochemical data interpretation, aquifer characterization and water supply studies.  She has earned a Master’s degree in Hydrogeology from the University of Calgary (Canada).  Ms. McCallum has provided technical guidance and expertise in the interpretation of physical, chemical, stable isotope and hydrogeological data for various projects in the sectors of Oil and Gas Industry, Agriculture, Environmental Firms, Government Agencies and Private Landowners.  She has worked as a lead scientist in the development of local to regional scale hydrological/hydrogeological assessments, water management plans, groundwater monitoring and water sourcing studies.

Dr. Stefan Kienzle
Geographic Information Systems and Water Resources
As a GIS and water resources specialist involved in a wide range of projects through academia and consulting in Canada and internationally, Dr. Kienzle has extensive experience in the areas of GIS data integration, database design, spatial analysis, geostatistics, terrain modeling, water resources analysis, and automatic mapping.
Dr. Masil Khan
Soil Scientist
Dr. Khan is an environmental soil scientist with key experience in soil quality assessment and management within Alberta and internationally. Dr. Khan’s research work focused on responses of soil microorganisms to potentially toxic elements (heavy metals) in sewage sludge/ biosolids-treated soils. He has worked on developing sustainable agriculture practices and how point and non-point pollutants affect freshwater ecosystems. Dr. Khan has also worked on bio-conversion of organic wastes with the multiple purposes of plant nutrient recycling and protection of soil and water quality. He has published most of his research findings in peer reviewed journals and presented his project findings in international conferences and workshops.
Dr. Ave Dersch
Traditional Land Use, Archaeology, Aboriginal Consultation

Dr. Ave Dersch has extensive traditional knowledge experience through her work and research with several First Nation communities. Her Ph.D. dissertation research involved looking at the application of traditional knowledge to past, present and future land use with the Swan River First Nation. Over the years, she has assisted with traditional land use studies, archaeological assessments and research examining contaminants in key cultural plant resources and water.
