FRESHWATER
STREAM
It's no problem at all at
Nerringillah to find examples of nearly all types of freshwater organisms,
even in a short twenty minute collection time. Using Sydney Water's Streamwatch
indicator species bug guide, students usually classify Nerrindillah stream
as excellent.
Using nets provided, students
usually find examples of stonefly larvae, mayfly larvae, shrimps, frogs,
beetles, spiders, mites, copepods, brown algae and green algae to name
but a few. All live specimens are returned to the stream to help ensure
it's continuing health. |

Students learn to identify
with keys, pictures, hand lenses and binocular microscopes all the life
they find. With a little help they can then draw a complete food web for
the stream, all in one session.
