With our gear carefully situated, listening to the quiet of the Rattlesnake Creek, we awaited the students of Chief Charlo Elementary. The school bus entered the parking lot of Greenough Park and the 5th graders rambled out, talking excitedly among themselves. The volunteers' anticipation mounted as the teacher, Kevin Cashman, lead the students across the bridge of the creek towards the workstations. And with a rush of joy and squeals of delight the kids were upon us, eager to dive into the world of macro-invertebrates.
First, a little context. To conduct a biological assessment of the Rattlesnake Creek, 300 macro-invertebrates are gathered to determine if a stream is polluted. Macro-invertebrates are animals that do not have backbones, but are visible to the naked eye. Certain macro-invertebrates are sensitive to pollution in the streams, such as mayfly and stonefly nymphs, and their presence or absence can indicate the overall health of a stream. The Watershed Education Network collects this data to keep community members aware of the quality of the water, and to empower students to understand the importance of our watershed.
The students rushed over to the tables, bubbling with enthusiasm as Mr. Cashman directed the kids into their groups. "Tanagers, and Western Meadowlarks will go into the creek! The Clark's Nutcrackers and the Pileated Wodpeckers will collect the bugs!" And with that the 5th graders scrambled about to their respective stations.
The Tanagers, about six kids, pulled on waders and armed themselves with nets, then went to the waters edge where I told them about the crab walk. "First thing is safety", I call out, "and to be safe in the creek we will be doing the crab walk whenever we are walking in it". With exaggerated movements, I demonstrate the crab walk, where you walk sideways down the river so as to avoid slipping. The kids head into the water and I take them down to riffles where the macro-invertebrates hang out. Three of the 5th graders eagerly hold the nets, while three others stand a few feet in front and start the shimmy. The shimmying disrupts the insects, and are directed by the current of the creek into the awaiting nets. Giggles echo out of the cool afternoon as the kids trade places, the former getting ready to shimmy, and the latter taking the nets. With the nets full of bugs and debris, the Tanagers head up to tubs full of water waiting on the bank where the nets are upended. With the task of netting the bugs finished, the children take the waders off and get ready to start collecting the macro-invertebrates.
Spoons and ice cube trays have taken the place of nets and waders, as I tell the 5th graders to search for the bugs like a stork, calm and unhurried. The Tanagers set about with quite a many "oohs" and "ahs" as the macro-invertebrates that they worked so hard to collect flit about the tub, diving for the leaves and other debris. With steady hands, the kids dip the spoons in, carefully uncovering and lifting the bugs out of the tubs and into the ice cube trays. "One macro-invertebrate per cube", I tell the Tanagers, as spoons laden with treasures appear out of the tub. Once a few fine specimens are found I take out the dichotomous key, an identification tool that consist of a series of choices that lead the user to the correct name and picture of an the macro-invertebrates that we are searching for. First, we look to see if the creatures have shells or not. "No shells!", the kids cry out. Second, we look to whether legs are involved with our little friends. "Legs!", the 5th graders say, and we continue down the key to the majority of the macro-invertebrates found in the stream being mayfly nymphs. After the Tanagers enthusiastically identify the creatures they are set free back into the Rattlesnake Creek.
Today was an exciting day for me. Experiencing the joy and vigor that a child greets its world with is uplifting to say the least. Moments of a persons existence are made when introduced early to the wonders of life. I feel very proud to hopefully be a part of something so significant. Being shown the beauty and life thriving silently in the river can be sometimes all it takes for a person to become acquainted with a sense of wonder that quietly guides them through life. Perhaps this placement of wonder actually took place, or perhaps a group of 25 children just had an absolute blast. Either one I will take. One thing for sure is that I look forward to more outdoor adventures with the Watershed Education Network, where we teach kids of the unseen world bustling in our streams.
