The Squamish Environment Society (SES) is a community-based volunteer organization working in the upper Howe Sound region of southwestern British Columbia. Our roots are deep in providing opportunities for members and others to enjoy and explore nature. We are dedicated to conserving wildlife and habitat confronted with the negative impacts of human disturbance and a changing climate.  We progress by blending field-based research, educational outreach, and engagement with others who share our mandate for biodiversity conservation and stewardship.  Contact Us

SES is a member of BC Nature, an affiliation of more than 50 natural history clubs province-wide.

We are a registered charity #860249630  RR0001.


SES was formed in 1982 as a result of a proposal by BC Rail to construct a port facility that would have reduced productive estuarine habitat to zero. SES members have spent countless hour at meetings, written hundreds of letters, conducted tours for residents, visitors and politicians advocating for the preservation of large areas of the estuary. This effort has resulted in improvements to the Squamish Estuary Management Plan and the creation of the Skwelwil’em Wildlife Management Area. Development pressures are relentless, so community vigilance is more important than ever.

Our original name was Squamish Estuary Conservation Society. In 2002, we changed our legal name to the Squamish Environmental Conservation Society to better reflect our concern for environmental issues beyond the needs of the Squamish Estuary. Our operating name is the Squamish Environment Society (SES). SES Constitution

We became a registered charity in 2020.
