As a science student who loves being outside, you spend most of your time exploring the docks and shorelines of local lakes. At the end of summer, you notice an abundance of mussels not previously seen. Signs also appear on the shores of stream and lakes, urging citizens to "stop the introduction of the zebra mussel." A news report explains that biologists are worried about an invasive species that might be spreading into your community. Being a concerned citizen, you enlist your friends to investigate whether this invasive species could be causing the demise of other native plants or animals. Together, you design a plan to investigate the problem, consulting with experts in the field whenever possible. You hope to present your action plan, which will include management strategies for the invasive species and a proposed recovery plan for the native species, to your local City Council and Parks and Recreation departments. |
