SER-WC Board of Directors 2020-2021

Erin Roberts (Chair) – Vancouver, BC

Erin is a problem-solving ecologist with professional experience in consulting and governments Alberta and BC. She is currently working as a Habitat Planner with the Canadian Wildlife Service, where she helps manage and restore federal protected areas for wildlife, migratory birds, and species at risk. 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 rock climber, skier, and reasonably proficient pickler.

Zachary Moore (Vice Chair) – Pincher Creek, AB

Zachary is a developing environmental professional working with Nature Conservancy Canada as an Assistant Natural Area Manager, where he helps to coordinate conservation strategies for a large buffer zone surrounding Waterton Lakes National Park. After working on several population ecology research projects in and after his undergrad, Zachary discovered his interest in how ecological theory is taken and applied by biologists working on the ground. This led him to Niagara College and a graduate certificate in Ecosystem Restoration – the “ultimate test of ecological theory”. As the Vice President of their student SER chapter, Zachary organized several small restoration projects through the college. Through this work, he developed a fascination with the multitude of public, private, and non-profit organizations that exist to further similar environmentally based goals, and how they can be better connected. Since moving to Alberta, the SER’s goal of connecting restoration practitioners the world over to share their knowledge has become one of Zachary’s true passions. His other passions include bugs of all kinds, cooking (eating), working with kids, and board games.

Dave Polster (Treasurer) – Duncan, BC

She is enthusiastic about field work and is skilled in planning and undertaking surveys for vegetation communities, terrestrial birds, amphibians, reptiles, and mammals in western Canada. Rebecca has a BSc in Forest Sciences from UBC and a MSc in Ecological Restoration from SFU/BCIT. She specialized in wildlife habitat management during both her academic programs and is passionate about using restoration as a tool for improving ecological communities for wildlife, particularly species at risk.


June Pretzer (Director) – Victoria, BC

I’ve restored natural and not so natural areas for a very long time now and see incredible potential for integrating natural systems into urban, industrial, and agricultural areas. As our knowledge increases, the benefit of integrating restoration into anthropogenic systems is more obvious and needed. I have a Graduate Certificate in Project Management to run projects more efficiently with improved stakeholder engagement and more fundraising experience than I care to think about. I’m Chair of the Coastal Invasive Species Committee whose range is Vancouver Island and the Sunshine Coast. I know a lot about invasive species identification, control, management, and legislation.

I strongly believe in the ability of just a few people to influence and direct change. As an organization of specialists with vast collective knowledge, SERWC provides the perfect home to expand our intellectual ecological landscape. We have so much more to do! Join us.

Andy Owens (Director) – Vancouver, BC

Andy has worked as Restoration Ecologist for Brinkman Restoration for the past 11 years, managing the design and implementation of terrestrial and aquatic restoration projects throughout Western Canada. His focus includes riparian and upland restoration, habitat enhancement in novel ecosystems, and restoration of soil health through microbial inoculations. Andy has a BA in Environmental Studies, Certificate in Restoration of Natural Systems and Professional Specialization Ecological Restoration. A Certified Ecological Restoration Practitioner (CERP), Andy currently sits on the Board of Directors for the Society of Ecological Restoration for Western Canada and the CERP program certification committee for SER International.

She then spent five years working in the Environmental Department at the Mount Polley Mine, BC. In 2016, she returned to UBC to do a PhD researching reclamation methods for improving recovery of the soil food web, and studying how belowground ecosystem recovery can relate to improved revegetation outcomes. Katie finished her PhD in 2020 and now works as an ecologist at Integral Ecology Group. In her spare time, Katie likes to ski, bike, bake and putter in her little garden. Katie previously worked as the SER-WC Media Coordinator in 2014–2015 and is happy to be re-joining the team.
