It was a phenomenal day on August 26, 2024, when Cathryn Pugh, Penn State Forestry Extension Educator, led a bunch of 25 grasp watershed stewards, trainees, and others on a stroll by Letort Spring Backyard Protect in Cumberland County, Pennsylvania. It was a day of soaking within the solar and absorbing data. The day’s purpose was to hone our native and native plant identification expertise.
Cathyrn’s data and love for flora had been evident the minute the stroll started. She began off by explaining totally different traits to search for to assist with plant identification, reminiscent of leaf sort (easy vs. compound) and leaf association (reverse vs. alternate vs. whorled). The magnitude of a distinction only one small element could make when figuring out vegetation was astounding.
As soon as we had sufficiently reviewed the traits to search for when figuring out vegetation, we walked on by the protect to our first cease – the American pokeweed. The pokeweed has easy leaves in an alternate association. The leaves are ovate, or widest within the center, they usually have a clean edge. Within the plant neighborhood, the sting of the leaf is known as the margin. A defining attribute of the pokeweed is the purplish coloration that’s current all through the totally different constructions of the plant, from stems to berries. They may look scrumptious, however the berries are poisonous to people. They make an important meals supply for birds and wildlife, although!
The following cease was not a lot additional alongside the path. Cathryn confirmed us a couple of examples of spicebush. Thought of a shrub by botanical definition, the spicebush is a tremendous plant. It is without doubt one of the earlier flowering vegetation within the spring, showcasing beautiful yellow flowers and producing vibrant purple fruits which might be beloved by wildlife. In addition they give off a scrumptious scent paying homage to lemons and citrus. To get a whiff, merely scratch the bark on the twigs or crush one of many leaves to launch the aroma. I would not advocate consuming the berries outright, although. The sturdy odor equates to a powerful style, and also you’ll be tasting spicebush for the rest of your hike. It is higher to gather berries and leaves to dry out at house and save to boost a dish later.

One other cease alongside the best way was to find out about black cherry timber. An figuring out attribute of those timber is their bark. As Cathryn places it, it appears to be like like “burnt potato chips.” One other useful however tiny identifier is the 2 little bumps, known as peptide glands, positioned on the petiole (the stalk that joins the leaf to the stem) proper earlier than the place the leaf begins. This attribute is current in all cherry species. As a part of the almond genus of vegetation nested inside the bigger Rosaceae household, the black cherry tree has a definite scent that followers of true crime would acknowledge as cyanide, and others would establish as merely “almondy.”
Through the stroll, we additionally had the prospect to find out about hackberry, honey locust, and vining vegetation reminiscent of bittersweet, grape, Virginia creeper, and poison ivy, however an article that critiques all the pieces coated on this plant identification stroll would go on for pages and pages. So as a substitute, I’ll cowl some insightful questions that had been requested alongside the best way.
Query: How do you inform the distinction between the invasive bittersweet and the native American bittersweet?
Reply: When the fruit is ripe, the capsules shall be orange on American bittersweet, and yellow on Asiatic bittersweet (Pavlovic et. al) *
Query: Are honey locusts nitrogen fixers?
Reply: Honey locusts are within the legume household, identified for fixing nitrogen with the assistance of rhizobia micro organism. Nevertheless, honey locusts don’t repair nitrogen, however black locusts do.
It was heartwarming to see contributors of all ages (starting as younger as two!) present as much as be taught one thing new. Visiting one of many extra tree-laden areas of south-central Pennsylvania gave a glimpse into the arduous work these vegetation are placing into sustaining our watershed. With out the vegetation and their soil-stabilizing nutrient-holding roots, our stunning waterways would look very totally different. Studying the specifics about most of the vegetation that work so arduous to take care of an ecological steadiness helped create an actual sense of appreciation inside the group.
By the tip of the stroll, we had scarcely made it greater than 1 / 4 of a mile by the protect. That’s the character of a naturalist hike, although. You commerce distance hiked for data realized, and it’s a commerce effectively price making!
