Macro Invertebrates and Stream Health with Rahway River Trout Unlimited
Please join us as Jon Dugan the NJDEP/AmeriCorps Watershed Ambassador will present to The Rahway River Trout Unlimited Chapter how certain macro invertebrates have varying degrees of sensitivity
to pollution. A macro invertebrate is a creature without a backbone that
can be seen with the naked eye.The presence of many varieties of macro invertebrate
indicates a healthy stream. Inversely the absence of macro invertebrates
indicates poor stream health. The over-all health of a stream can be
evaluated by enumerating all the
species of macro invertebrates found in samples collected from a stream
during a set time. Jon will also cover stream entomology & how to
properly i.d. insects that are in the river.
