Avoid Invasive Species
If you don't know it, don't grow it. Avoid buying or growing plants such as purple loosestrife, English ivy, ribbongrass, and butterfly bush that are known to be invasive.
Be especially careful when buying plants and seeds on the internet or by mail order. You may unknowingly contribute to the spread of an invasive species from one part of the country to another. Although some companies have voluntarily withdrawn known invasives from sale or labeled these species high risk, many have not.
What You Can do for Clean Rivers and Streams
Many of our common, everyday activities can affect the health of our urban watersheds. When it rains, stormwater runoff that isn’t properly managed can wash over streets and other hard surfaces and carry pollutants into our rivers, streams and groundwater. We can all work together to keep our watersheds healthy and our rivers and streams clean.
