Last autumn, on a hot, humid Sunday afternoon in early October, my son Dave and I led a Walk in Penn’s Woods on our property. This program, begun in 2017 by the Center for Private Forests at Penn State, has attracted support from both private and public land owners eager to share their forests and the trees, shrubs, wild flowers and wild creatures that inhabit them.
Our walk was the only one scheduled in Blair County, and we did not advertise it ahead of time. Still, we had one man from Centre County, another from our county, and a couple from Indiana County.
From our 10 miles of trails, Dave and I had chosen the walk up our mile-and-a-half entrance road paralleling our Plummer’s Hollow stream, through a mostly diverse hardwood forest that also has a stand of hemlocks affected by hemlock woolly adelgids. Many of the trees in the hollow date from the 1840s when it was last clearcut to feed the iron furnace at the base of our road known as Upper Tyrone Forge.
Since visitors to our property first drive across an old couty bridge over the Little Juniata River and then bump across the main railroad line from New York to California, we are able to point out the remnants of the watering tank near the bottom of our stream which was used by the steam locomotives beginning in 1850. It was first overseen by the original William Plummer who came here in 1832 to work as a forge man and ended his life working on the railroad.
Human history that impacted our forest was important, but so was learning about our forest today and the plants and animals that live in it. Because the trees are old and the understory on the steep slopes of Laurel and Sapsucker ridges fairly diverse, we were able to show our visitors a wide variety of native tree species and their fruits from cucumber-tree and American basswood to American beech, red, black, white, chestnut and scarlet oaks, white pine, sugar and red maples. All of these species and more provided dense shade that made the walk pleasant.
A Sunday afternoon in early October was not the best time to see or hear the many songbirds that live in this forest, but we could at least mention the red-eyed and blue-headed vireos, ovenbirds, scarlet tanagers, Acadian flycatchers, Louisiana waterthrushes, wood thrushes, black-throated green, hooded and worm-eating warblers and other birds nesting here in spring and summer, and the year round species such as black-capped chickadees, white-breasted nuthatches, and downy, hairy, red-bellied, and pileated woodpeckers, for instance.
The wildflower season was also waning, but I did show them blooming beechdrops, wavy-leaved asters, and blue-stemmed goldenrod. In addition, I identified native shrubs—maple-leaf viburnum, red-berried elder, wild hydrangea, spicebush, mountain laurel, and my favorite rhododendron–while Dave pointed out the various tree species.
Halfway up the road we were able to feature a large white oak growing atop the flat remains of a charcoal hearth as well as the chunks of charcoal beneath the thin layer of topsoil.
Since our goal is to let our forest mature into old growth, when trees die, we let them fall and rot to provide more soil and have so many dead snags that birds, bats, gray, fox and flying squirrels and other mammals have no trouble finding nesting holes. We also told our bear, fisher, and coyote stories and mentioned the success of the Game Commission’s program to bring back the extirpated fishers. In addition, the Commission’s efforts to increase bald eagle numbers has led to nesting bald eagles on game lands at the other end of our mountain. This was a gift we had never expected to see in our lifetimes.
We led our visitors to the base of Guesthouse Trail to point out the small rhododendron exclosure Dave had built to keep the deer away from this shrub that is a favorite of theirs especially during the winter months.
And finally we went on to our three-acre exclosure in a part of our forest with a white oak and several red oak trees that date to 1812. Despite our successful hunter program with excellent hunters on our land from the beginning of archery season in October to the end of flintlock in mid-January, our visitors could still see the difference between the open forest outside the exclosure and the dense understory inside including the numerous oak, white pine, black gum, and maple saplings.
In the heavily forested portion of our property, primarily on Laurel Ridge, we have little trouble with invasives, but our 37-acre meadow and the 125 acres we purchased on Sapsucker Ridge after it had been high-graded back in 1991 are infested with barberry, mile-a-minute, stiltgrass, multiflora rose and other pernicious non-native plants, most of which provide little or no nourishing food for birds and mammals, unlike our native trees and shrubs.
Invasive plants and diseases, tree, shrub, and wildflower identification, wildlife, including birds, mammals, reptiles and amphibians, and forest management seemed to be the dominant themes in the 68 walks in 48 counties attended by 1,136 people last autumn.
For instance, at the 50-acre Laura Olsen Memorial Sanctuary walk in Crawford County, hosted by Presque Isle Audubon Society and the Foundation for Sustainable Forests, they entitled their walk “Exploring Forest Bird Habitat” where as many as 51 species have been documented in this forested wetland.
The Musser Gap walk in Centre County, which attracted 66 participants, had 10 stations leading into Rothrock State Forest. There were handouts at the parking lot and leaders at every station that covered forest management, natural or cultural topics.
The Pennypack Ecological Restoration Trust in Montgomery County led a walk around the wooded areas of Pennypack Creek that featured a native persimmon tree with fruit and the fruit of a black walnut tree. Visitors saw an American kestrel and sharp-shinned hawk and identified bird and animal calls. The leaders explained why they had wrapped trees in preparation of the deer rut. At a pond everyone heard frogs and saw a beaver lodge.
In Bedford County, Mike and Laura Jackson led 22 people over their mostly wooded property. They walked through part of their woods that was high-graded back in the 1980s and talked about how that type of logging creates an unhealthy forest. They pointed out invasive species and the impact of too many deer on the forest even though Mike does his best during hunting season.
They also have a shelterwood cut that was done in the autumn of 2014 and enclosed by an eight-foot-high fence. On a trail through the exclosure, they identified the native trees and shrubs that have appeared such as sassafras, both hornbeam species, and quaking aspen in addition to stump sprouts of tulip poplar, black cherry, oak, elm and red maple that are already almost 20 feet tall.
The large seed trees that were left after the shelterwood cut included shagbark and pignut hickory, black cherry, sugar maple, tulip poplar, white and red oaks, butternut and American basswood, all of which provide excellent wildlife food.
That was the second Walk in Penn’s Woods the Jacksons’ hosted. On each walk, like most folks on these walks throughout the state, walkers were interested in learning how the Jacksons have managed their woods for wildlife and what birds and animals live there.
In Lancaster County the Game Commission’s Middle Creek Wildlife Management Area sponsored a walk on a nature trail with 10 stations featuring wildlife and forest management techniques and tree identifications.
State Game Lands #37 in Tioga County, hosted by the Tioga County Group Effort, attracted 27 people who learned about game food plots, timber harvesting, wildlife and general forest management principles.
A few of the walks were stroller and wheelchair accessible and, as such, attracted over 30 people. One was in Montour County at the Montour Preserve where they were led on the Goose Woods Trail by Jon Beam who has been associated with this preserve for decades and once showed me the signs of American woodcock during a visit.
At Tuscarora State Park in Schuylkill County 33 people walked on a wheelchair-accessible paved path around Tuscarora Lake where they learned to identify the trees and shrubs of this forest and were told about the forest benefits to humans and wildlife.
Because of the popularity of wheelchair and stroller accessible walks, this year’s organizers of the Walk in Penn’s Woods on October 6 hope to have more such walks in what they are calling Walk and Roll in Penn’s Woods. But many of the same walks as last year plus new walks are featured on their website.
For most walks there is no reason to sign up ahead of time. Just pick your walk anywhere in the commonwealth and go. You are bound to learn something new about Penn’s Woods and meet knowledgeable people both leading and attending the walks.
