In Memoriam: Cass Turnbull and Mike Bowman

Cass Turnbull

February 7, 1951 – January 26, 2017

In late January, we were all saddened to learn of the sudden and unexpected death of well-known PlantAmnesty founder Cass Turnbull. While vacationing in Hawaii with her husband, she suffered a fatal heart attack after a swim. Cass was the power, the energy, the humor, and the magic behind PlantAmnesty, a long-time member of ISA and the PNW Chapter, and she will be missed by all who knew her.

PlantAmnesty is organizing a public celebration of her life called “The Life and Times of Cass Turnbull” at 1 PM on Saturday, March 25, 2017 at Shoreline Community College Theater in Shoreline, WA. Further information can be found at

In lieu of flowers, contributions in memory of Cass may be made to PlantAmnesty or TreePAC.

An obituary that was published in The Seattle Times on February 5, 2017 is available online.

Other tributes include an online article by Lynda Mapes of the Seattle Times and an article by Peggy Sturdivant in the Ballard News-Tribune.

Mike Bowman

September 12, 1935 – January 23, 2017

Sadly, the PNW Chapter lost another champion of trees and urban forestry this past January. Mike Bowman, of Moscow, ID, spent 15 years as the City Forester in Lewiston, ID, and served one year on the PNW Board of Directors, as Secretary.

David Stephenson, Community Forestry Coordinator for the Idaho Department of Lands, paid tribute in “Farewell to an Idaho Tree Man,” in the most recent issue of the Idaho Community Trees newsletter ... be sure to turn to page 2 of the newsletter to see a photo of Mike.
