Dr. Brad Stelfox

Founder, Landscape Ecologist

Dr. Brad Stelfox established Forem Technologies and the ALCES Group in 1995 and is the architect and developer of the ALCES model. He is an adjunct professor at the Department of Biological Sciences, University of Alberta, and the Department of Environmental Design, University of Calgary. Brad's research and teachings focus on the interface between human land uses and regional landscapes. The major development stream of Forem has been ALCES (A Landscape Cumulative Effects Simulator), a program gaining rapid acceptance by governments, industry, the scientific community, and NGO's to explore issues between landscapes, land uses (agriculture, forestry, oil and gas, mining, human populations, tourism, and transportation sectors), and ecological and economic integrity. Dr. Stelfox has received the Alberta Emerald Foundation Award (2004) and the Alberta Science and Technology Award (2003) for his contributions with the ALCES model in advancing understanding of land use sustainability issues and in seeking solutions that balance economic, social, and ecological indicators.

Brad and his wife Sarah live in Calgary. When Brad is not working on the ALCES model or guest lecturing on land use issues, he is likely on horseback exploring the mountain trails of Alberta's east slopes.

Matt Carlson


Matt is an ecologist interested in applying a systems dynamics approach to communicate land use concepts and develop pragmatic solutions to natural resource management challenges. Over the past ten years, Matt has developed and applied simulation tools to explore the future effects of land use in a variety of landscapes from the Mackenzie Watershed in northwestern Canada to the Mbaracayu Biosphere Reserve in Paraguay.  Recent projects have focused on applying ALCES to inform the development of land-use plans that appropriately balance ecological and socioeconomic objectives.  Matt is also an ecologist for the Canadian Boreal Initiative, and has a Masters of Science in Conservation Biology from the University of Alberta. Matt lives in Ottawa with his wife and two children.  When not at work Matt can be found running trails, or after his kids.

Justin Straker

Soil Scientist, Forest Ecologist

Justin Straker is a soil scientist and forest ecologist, and a principal of the Integral Ecology Group in Victoria, British Columbia. Justin has over 15 years of experience in applied terrestrial ecology, focusing on three primary areas:


 1.       terrestrial reclamation of industrial disturbances, including design, implementation, assessment, review and regulatory inspection of reclamation and reclamation-research programs for the mining and forestry sectors;

2.       terrestrial environmental-effects research/biomonitoring programs, including  design and implementation of studies on the effects of industrial atmospheric emissions and fugitive dusts (acidifying emissions, nitrogen and metals) on terrestrial ecosystems; and
3.       assessment of the interactions of human land uses and other ecosystem components, including development of land management frameworks and State-of-Environment reporting. 

In his work, Mr. Straker has provided technical advice and research support to industry, government and stakeholder clients throughout western Canada, and in Quebec and Peru.

Dr. Shanti Berryman

Vegetation Ecologist, Lichenologist

Shanti Berryman is a vegetation ecologist, and lichenologist with more than ten years of research and consulting experience related to terrestrial ecology, lichenology, biodiversity, air pollution and environmental sciences. More recently, she has been working with Aboriginal communities on environmental and land management issues in western Canada. Shanti has applied her knowledge to a diversity of projects focusing on terrestrial ecosystems, biodiversity and land‐use within the Alberta, and in Alaska, Oregon and Washington. Since 2002, Shanti has worked extensively on social‐environmental issues related to impacts of air quality and industrial development on ecosystem health in the area of oil sands development of northeastern Alberta.

Shanti is currently an adjunct professor at University of New Mexico. She provides technical advice and research support to industry, government and stakeholder clients in Alberta, British Columbia and Alaska. Shanti is currently an adjunct professor at University of New Mexico and she provides technical advice and research support to industry, government and stakeholder clients in Alberta, British Columbia, Saskatchewan, Alaska and Hawaii.

Ann Garibaldi


Ann Garibaldi has more than fifteen years of experience related to ethnobotany, traditional ecological knowledge (TEK), traditional use studies and vegetation ecology. She has worked extensively with indigenous communities in Alberta, British Columbia and Alaska on social-ecological issues in changing environmental systems.

Ann�s work explores processes to support meaningful and respectful dialogue between indigenous communities, government, industry and the private sector, with an emphasis on the interface between traditional knowledge and western science. Ann has brought her expertise and training in botany (B.Sc. Ohio University) and Ethnobotany (M.Sc. University of Victoria) to bear on issues related to: TEK and Traditional Land Use in mine reclamation processes; forest harvest management practices that support traditional land use; biodiversity and wildlife habitat reclamation and land management decisions, and more. Her approach emphasizes community participation in defining the project intent and outcomes, and she is committed to inclusive relationships with communities with whom she works. Ann has developed and executed multiple training courses on TEK discourse and applications. She has authored the book Medicinal Flora of the Alaska Natives (Garibaldi 1999) and sits on the Ethnobotany Advisory Board with the University of Alaska.

Jennifer Janzen

Alberta Tomorrow Project Coordinator

Jennifer Janzen joined the ALCES group in 2008 as the project coordinator for Alberta Tomorrow, a web-based educational land-use simulator. She holds a Bachelor of Science in Land Use & Environmental Studies and Biology, and a Bachelor of Education from the University of Saskatchewan and has worked for various government and non-profit organizations as a plant ecologist and educator in Saskatchewan and Alberta. She taught high school Biology in Alberta for 10 years while at the same time working with the Elbow River Watershed Partnership and Parks Canada to develop lesson plans on various environmental issues.   She and her husband now live in Cochrane, raising two wonderful daughters and instilling in them an appreciation for our natural world.

Dr. Michael Sullivan

Dr. Michael Sullivan

Fisheries Ecologist

Michael Sullivan's passion for wildlife has led him through three academic degrees at the University of Alberta and 25 years of fisheries, wildlife, and landuse management with the Alberta Fish and Wildlife Division. For much of this career, Dr. Sullivan's work has been focused on resolving fisheries and aquatic issues in the Lakeland and Athabasca areas of north-eastern Alberta. His successful work on restoring northern Alberta's walleye fisheries through the interaction of scientific models and public involvement has resulted in awards and recognition at local and international levels. Through close working relationships with other landscape management and research agencies (e.g., Parks Canada, Alberta Conservation Association, Alberta Cooperative Conservation Research Unit, Department of Fisheries and Oceans), Dr. Sullivan has built a network of strategic learning around the complex interplay between ecological and social systems. Michael is currently the Provincial Fisheries Scientist at Alberta Fish and Wildlife Division, Department of Sustainable Resource Development. He is also a Visiting Scientist at the Department of Renewable Resources (University of Alberta), where he is supervising graduate students, coordinating landscape-level research programs, and participating in ALCES projects with his colleagues at Forem Technologies.
