Suction Dredge Mining Impacts On Pacific Lamprey Populations And Habitat In Washington State: A Case Study Of The Entiat River, Jaime Liljegren
Suction Dredge Mining Impacts On Pacific Lamprey Populations And Habitat In Washington State: A Case Study Of The Entiat River, Jaime Liljegren
All Master's Theses
Suction dredge mining is a largely unregulated recreational activity in Washington State with potentially significant impacts to aquatic habitat. Although dredging has the potential to cause widespread ecological effects, only impacts to select species have been thoroughly assessed. Due to their reliance on freshwater habitat throughout multiple life stages, Pacific lamprey are significantly vulnerable to impacts from dredging practices. This thesis focuses on assessing the effects of dredging to lamprey habitat within state-owned aquatic lands of Washington. Pacific lamprey are anadromous, utilizing freshwater habitat throughout key life stages including spawning in substrate ranging from coarse gravel to fine sand, and …

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …
