Why are white sturgeon endangered?
The reasons upper Columbia white sturgeon are endangered are not fully understood however in the last 125 years, human development, loss of habitat, pollution, construction of hydroelectric dams and changes in flow patterns, the introduction of exotic species and harvesting in the upper Columbia River has led to the sturgeon’s decline. Collectively, these factors have endangered the white sturgeon by reducing their reproductive success, restricting their distribution and degrading their habitat.
