The Squamish Environment Society (SES) is a grassroots non-profit organization dedicated to wildlife and habitat preservation. We are committed to achieving balance between the needs of wildlife and human desires in order to achieve long-term sustainability of natural ecosystems in the Squamish area. We seek to engage the community in enjoyment, respect and responsibility for the natural world, through advocacy, research and education.

We are based in Squamish, British Columbia and focus our efforts in the upper Howe Sound area and the watersheds that feed it. 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.
