Calculcations and Benthic Macroinvertebrates

Road construction greeted us in the morning as we struggled to find open parking spaces!

A morning spent making sense of forestry data doesn't photograph well. But in the afternoon, we had an opportunity to get in the river and sample benthic macroinvertebrates.

Wading into the Jackson River.

Setting up a sampling net.

Scrub those rocks! Get all the "bugs" into the net!

Bringing the net back to the banks to collect and identify the macroinvertebrates.

Starting the long process of collecting all the invertebrates, then separating, grouping, and counting them.

Hellgrammites are among the invertebrate larvae commonly colleccted in the stream. This is an adult hellgrammite -- a Dobson fly, about 5 inches long -- on a light post in the DSLCC parking lot.
