►You have just learned how to use living You have just learned how to use living organisms to classify primary organisms to classify primary headwater streams. This is called Bio-headwater streams. This is called Bio-Assessment and is more accurate than Assessment and is more accurate than using the HHEI assessment of physical using the HHEI assessment of physical parameters. parameters.
