Generate High-Quality PDF

The Portland/Vancouver Basin ecoregion is composed of undulating terraces and floodplains with numerous wetlands, oxbow lakes, and ponds. Historically, prairie and oak woodland grew on better drained sites while wetlands, Oregon ash, and Douglas-fir occurred elsewhere in the fault block basin. Today, The Portland/Vancouver Basin ecoregion is dominated by urban and suburban development, pastures, and nurseries. Weather here is often affected by cold or warm easterly winds that blow through the Columbia River Gorge.
