The first part of the day was spent examining rocks in the Doe Run stream. The students were looking for aquatic insects.
They were given a demonstration and shown pictures of various types of insects they might see.
Some species can only survive in very clean water, so their presence is an indication that the stream is not polluted.
The students were shown how to use paintbrushes to collect insects, so that they would not harm them.
Sam S. waded right in to find some rocks for his classmates to study.
He told us the water was cold!
He discovered just how cold it was when he slipped!
He was a good sport about it!
The specimens were collected in cups.
Everyone found a lot of insects.
The insects we found included lots of Mayflies, one of the sensitive species, so that is an indication that the Doe Run is a healthy stream.
The students had a lot of questions for the Conservators.
After the stream study, it was time to create a riparian buffer. Here are a few of the trees that we would plant.
One of the Brandywine Conservancy's staffers demonstrated the proper way to plant a sapling.
Then the 8th and 9th graders got to work. They had to carry the trees to their sites, and dig holes.
After taking the trees out of their pots, they loosened the roots.
They had to be sure to eliminate air holes as they filled dirt in around the roots.
Some of the boys worked in pairs.
Mrs. Anderson, an experienced gardener, worked alongside the boys.
Thanks in part to the efforts of the 8th and 9th grade boys, the Doe Run stream at the Laurels preserve will remain a healthy aquatic habitat.
