Preventing the introduction of aquatic invasive species (AIS) like zebra and quagga mussels in the U.S. is a high priority. This Capstone demonstrates zebra and quagga mussels are of concern as aquatic invasive species and a volunteer monitoring and intervention program is an effective means for early detection of AIS. This Capstone developed an AIS citizen volunteer lake monitoring program consistent with other programs concerned about AIS prevention and early detection. This Capstone concludes implementing such a voluntary program will help reduce the spread of zebra and quagga mussels and will provide early detection information to appropriate agencies empowered with response actions if species are found.

As threatened and endangered species, wild Pacific salmon are in peril. This paper discusses the differences of the five species of wild Pacific salmon. As salmon go through several stages of their lifecycles, they face a myriad of threats to their existence. Threats from humans in the form of hydropower dams, habitat destruction, harvesting issues, and hatcheries are explained. A draft recovery plan for salmon in the Puget Sound area of Washington State is used as a case study. Strengths and weaknesses of this plan are discussed. The paper then discusses the need for growth management laws supporting salmon habitat and a change in individual behaviors if wild Pacific salmon sustainability is to become a reality.
