About Us
History
Mike started Pearson Ecological in 2001 while a graduate student at UBC. We remain a small operation specializing in field based projects involving freshwater fish, species at risk and aquatic habitat restoration. We work primarily in the Fraser Valley and frequently collaborate with First Nations, academic researchers, and non-profit organizations.
Our Commitments
- Only take on projects that contribute to stewardship or conservation in some way
- Work collaboratively with Indigenous communities and organizations
- Develop and use minimally-invasive methods of monitoring populations and habitats
- Provide public access to our data and reports whenever possible

Fernando is not technically part of Pearson Ecological, but he is a close collaborator and certainly a part of this website! Many of the most beautiful images here are his, some taken in the field with us, and some from his other adventures as a professional photographer. More stunning images can be found in his new book, Urban Salmon and at Fernando Lessa Photography
