Western Canada Chapter Board of Directors 2017-2018


Darcy Henderson (Chair) Kelowna, BC

Darcy has 25 years of experience in the environmental field.  He is Head of Protected Areas and Stewardship (Prairies) with the Canadian Wildlife Service, and Adjunct Professor with the University of Saskatchewan where he teaches PLSC 398.3 Environmental Restoration.  His work with ecological restoration involves research, management and practical experience in prescribed burning, native seed collection, re-seeding disturbed sites, modifying grazing practices, controlling invasive alien plants, as well as survey design, monitoring, and assessment of species at risk populations, plant community diversity, soil salinity and organic matter, and health of wetlands, rangelands, and boreal forests.  He has PhD and MSc degrees from the University of Alberta, a BSc from the University of Saskatchewan, and a Diploma in Resource Management from Saskatchewan Polytechnic.


Erin Roberts (Vice Chair)


Erin is a problem-solving ecologist with professional experience in consulting and local governments Calgary and Vancouver. She is currently working in environmental assessment with Parks Canada in Banff National Park. Her roots were formed at the University of Waterloo in an interdisciplinary Environment and Business (BES) program – and she has since completed the Ecological Restoration MSc program from BCIT and SFU. For her graduate research, she investigated monitoring metrics in intertidal estuarine restoration, and is fascinated with the role of resilience and succession in ecosystems. Wetlands, watershed management and disturbance histories in Western Canada are her specialty, but she often finds herself learning and working in other ecosystems. It’s good to mix it up.

She’s excited about restoration because she believes it helps people better understand and appreciate the complexities of nature in a practical way. She’s also a sport climber, skier, and reasonably proficient pickler.

Douglas Hallet (Director)

D. Hallett (Director)Douglas is a specialist in fire, climate change, and disturbance ecology. He has published several long-term fire histories using sedimentary charcoal records to reconstruct ancient forest fire activity. This research has a regional to global scope and analyzed deposits of charcoal embedded in lake sediments, peats, and soils using chronological control by way of radiocarbon dating, volcanic tephra layers, and tree rings. As a restoration ecologist, I strive to develop a deep time look at landscapes and ecological processes to provide a richer knowledge of natural history that may help us to understand important lessons for moving forward.

Through his research, Douglas has developed a keen interest in natural hazards and extreme events linked to climate change and atmospheric processes. Natural hazards, such as forest fires, debris flows and floods, across western Canada will require long-term consideration as we continue to plan and build sustainable communities.

As a vegetation and wetland scientist he is interested in advancing ecological restoration of wetlands, developing monitoring programs, and bioengineering solutions for disturbed ecosystems. His professional activities and university teaching experiences have allowed him to study the science of landscape-level conservation, ecological restoration, and issues related to wildlife populations across the Cordillera.

The International Panel on Climate Change (IPCC) 2013-14 reports clearly demonstrate that adaptation to a changing climate system is our biggest societal concern moving forward into the new millennium. Our conservation and restoration efforts must recognize potential large-scale shifts in biological systems while being sensitive to landscape context, human activities and disturbance legacies.

Shane Byrne (New Director)


Shane Byrne is an ecologist focusing on aquatic restoration. Hailing from Maple Ridge BC, he has called the Fraser River valley home for his entire life. Being in such close proximity to a major river system provided the foundation for studying the environment and human impacts on natural systems. Shane received his BSc in applied biology from Simon Fraser University and is now working towards his MSc in Ecological Restoration from BCIT and SFU’s joint program. Ecological restoration provides an interdisciplinary approach to difficult problems and challenges practitioners to tackle projects with a scientific approach. Restoration project management is an area Shane hopes to progress into.

Throughout university Shane worked as a commercial salmon fisherman. This work experience drove his interest in restoring salmonid habitat and contributing back to a key component of BC’s environment, economy, and culture. Currently he is completing his applied research project on the Salmon River diversion dam on Vancouver Island. He will produce a restoration plan for infrastructure removal and to reintroduce salmon migration to the upper watershed.

Upon graduation Shane aims to restore streams, estuaries, and wetlands both at home and abroad. He is excited about the impacts he can have on restoring the environment and combating climate change. Outside of school Shane enjoys being active and exploring the outdoors both on land and by water.
