WNPS also works in cooperation with other non-profit groups, such as the Seattle Audubon Society on public education and advocacy efforts.

The founding president was Arthur Kruckeberg, author and Professor Emeritus of Botany at the University of Washington.

The society has funded and published scholarly papers, called the Douglasia Occasional Papers.^[2]
