What lives in a stream and why?

Using biological monitoring to find problems in a watershed.

Finding and tallying what plants and animals live in a stream is called biological monitoring. Biological monitoring is like being a detective. If the living things found do not match what we’d expect to find in a stream, river or lake, there could be a problem. It’s a clue that we need to collect more data and information to find out where pollution is coming from and what to do about it.

Watch a news clip


Watch a 3-minute video that shows biologists collecting insects from streams in Minnesota. Then, investigate two streams using the activity sheet, just like these biologists would do at their job. Answer the writing prompts about what you notice, wonder and think.
