WATER QUALITY: WHEN IT’S NOT CLEAN AND HEALTHY
|
|
How do invasive species influence—both positively and negatively—the world’s water systems?

This session will take place online on May 16th, 2012 at 11 am ET (Washington, DC) / 4 pm UTC/GMT and last approximately one hour. See the date and time of this event in your time zone. If you cannot participate live, a recording will be made available following the live event for your enjoyment at any time.
Join a discussion of the effects of invasion species on water quality around the world. Some invasive species have had a positive effect. Introduced zebra mussels, for example, have reduced algal growths in the Great Lakes. Other species, such as exotic plants, can drastically alter soil nutrient dynamics and ecosystem processes in terrestrial systems.

In this session, we discuss what forests do with the precipitation they receive and how those forests can alter water flows in soil and streams. Using long-term data, Jess discusses the ways in which these processes are dependent on forest management.

Nitrogen and phosphorus are necessary to all living things, and we work hard to supply enough of them to crops, gardens, and lawns. These elements, however, can cause health and environmental problems when they get into our water. We’ll talk about how research helps us understand where these elements come from, the problems they cause, and ways to reduce those problems.
