Bright and early on a crisp Sunday morning, Jared Manzo, NMRWA’s GreenLinks Coordinator, guided participants on a tree identification walk through the lower section of Nine Mile Run. With rubber boots required, the first half of the walk traveled in or along the stream itself where no official trail exists.

Several species of trees were highlighted along the stream such as American sycamore, black willow, honey locust, silver maple, boxelder, common hackberry, and hardy catalpa. In a small patch of changing sugar maple, Jared explained what triggers dormancy in trees, the chemicals that produce fall color, and why leaves change color at all with the onset of dormancy.

Before moving back up to the Nine Mile Run Trail, Maranda Nemeth, NMRWA’s Restoration Stewardship Coordinator, took a moment to discuss a project along the run to allow fish to move further up stream. We returned to our starting point on Commercial Avenue by jumping onto the Nine Mile Run Trail. Some interesting species noted along the trail were staghorn sumac, black birch, sassafras, black gum, and bitternut hickory.

Overall, twenty-one tree species were identified. Tree identification focused on the most recognizable features of a given species to help distinguish it in the future. Leaf arrangement, simple leaves versus compound leaves, and the definition of a twig were discussed as well. Hot apple cider and muffins were great snacks given the chillier than usual October morning.
