Symbolism and conception in Cascadian Flag
Alexander Baretich who designed the flag in the mid-1990s.
He has said about the flag:
I designed the Cascadian flag, aka the Doug, way back in the mid-1990s. When I was a graduate student studying in Eastern Europe.
Though I totally love the people, cultures, and landscape of Eastern Europe.
I was deeply homesick for the forests of Cascadia, specifically the Willamette Valley forests I grew up around.
One day as I sat on a hill with my companion. I had this vision of a flag where the Cascadian landscape came to mind.
Prior to the design and its popularity, the idea of Cascadia–specifically the bioregion. It was pretty much an abstract concept reserved for radical geographers and hip sociologists.

The flag conveys something far more tangible than an abstract concept of demarcation of space; the flag captures that love of living communities in our bioregion.
Unlike many flags, this is not a flag of blood, nor of the glory of a nation, but a love of the bioregion; our ecological family and its natural boundaries; the place in which we live and love.
Basically, the flag consist of three horizontal stripes, and a Douglas fir in the middle of it stands vertically.
The flag characterizes the natural beauty of the bioregion of Cascadia. The three defining and most prominent natural elements of Cascadia are the water resources, the green forests, and the snow.

Description of the symbolism:
The blue stripe represents the sky, the Pacific Ocean, and the Salish Sea. As well as the myriad of rivers in the bioregion including the Columbia, the Snake, and Fraser Rivers.

The white represents clouds and snow and the green represents the region’s countless fields and evergreen forests.
The tree symbolizes “endurance, defiance and resilience against fire, flood, catastrophic change, and ever increasingly against the anthropocentric man”
