I made a video from the benthic macroinvetebrates workshop of last week.

We're back (finally)!

Stewardship has resumed last week after six weeks of interruption due to the garbage strike. As in previous years in August, it was time for the benthic invetebrates workshop. This workshop was offered to all the stewards including those of other sites. There were about 20 people in attendance. The workshop was presented once again by a member of Citizen's Environment Watch. My post from last year's workshop explains in details the process.

Stewards getting ready to wade into the ponds.

Walking in the ponds. It's hard to keep your balance.

We applied a slightly different method for the collection of insects this year. One person was simply walking in the pond in order to bring the insects closer to the surface as they tend to remain at the bottom, while a second person was moving the net back and forth in order to collect the insects.

Among the insects collected were midges and sow bugs which are the most common.
