During the past week, Uncle Tyler Dyer has been out searching for autumn leaves to add to his collection. One of the species he had not encountered in previous outings was the American Elm (Ulmus americana), so he made a special trip to see a rare mammoth specimen in a small neighborhood park (Park Place) along Chestnut Street between 5th and Quince Streets in Lebanon, Pennsylvania.
Possibly the largest and oldest remaining American Elm in the lower Susquehanna watershed, the Park Place tree in Lebanon exceeds 60 feet in height and may be more than 300 years of age. In the nearly one hundred years since Dutch elm disease (DED) first began killing elms in eastern North America, this tree has been spared the fatal effects of the infection. DED is caused by several species of microfungi (Ophiostoma ulmi, O. himal-ulmi, and O. novo-ulmi) spread by numerous bark beetle (Curculionidae) species. As early as 1928, infected beetles arrived in the United States from the Netherlands among shipments of logs.Leaves of the American Elm.
There’s still time to get out and see autumn foliage. With warmer weather upon us—at least temporarily—it’s a good time to go for a stroll. Who knows, you might find some spectacular leaves like these collected by Uncle Ty earlier this week. All were found adorning native plants!
Winged Sumac (Rhus copallina), a small native tree. In case you’re wondering, it’s not poisonous.Black Chokeberry (Photinia melanocarpa), a native shrub also known as Aronia. It produces black-colored fruits in summer.Red-osier Dogwood (Cornus sericea), a shrub that prefers wet or damp soils. It yields white fruits.Maple-leafed Viburnum (Viburnum acerifolium), a native shrub of upland forest understories.Highbush Blueberry (Vaccinium corymbosum), a native shrub and the source of many cultivated forms of the popular fruit.To identify your finds, be certain to click the “Trees, Shrubs, and Woody Vines” tab at the top of this page to check out Uncle Ty’s extensive collection.
Let’s have a look at some of the magnificent native wildflowers blooming on this Mother’s Day in forests and thickets throughout the Lower Susquehanna River Watershed.
Rue Anemone (Thalictrum thalictroides) is a fragile little wildflower of open woods.The Blackhaw (Viburnum prunifolium) is a shrub of thickets and forest borders. The flower clusters mature into an abundance of berries relished by birds and other wildlife.A large Black Cherry tree adorned in white blossoms can be pleasing to the eye and very beneficial for pollinating insects.The Common Pawpaw is a small tree of damp well-drained soils. Where conditions are ideal, it may form clonal colonies in the forest understory. The deep maroon blooms mature into banana-like fruits, hence its alternate common name “Custard Apple”.The Mayapple or Mandrake (Podophyllum peltatum) commonly blankets the forest floor. It, like other ephemeral wildflowers, is vulnerable to invasions by non-native shrubs that leaf out earlier in spring than native species and rob them of sunlight during their already abbreviated growing season.
Aren’t they spectacular?
Why not take a stroll to have a look at these and other plants you can find growing along a nearby woodland trail? You could check out some place new and get a little exercise too!
If you go, please tread lightly, take your camera, mind your manners, and…
From a lookout atop an Eastern Hemlock, a Northern Mockingbird maintains a vigil over a garden full of berry-producing plants. To assure their survival during cold weather, these bold birds will vigorously defend winter food supplies on hollies, viburnums, poison-ivy, bittersweet, and other fruit-producing trees, shrubs, and vines, often swooping in to startle and flush birds and other animals that approach its stores too closely.
Migrating American Robins feast on the juicy red fruits of a Guelder Rose (Viburnum opulus), a European shrub distributed for conservation plantings under the name Highbush Cranberry. The North American version of Highbush Cranberry (Viburnum trilobum), is very similar and is considered by some authorities to be a subspecies of V. opulus.
On a snowy winter day, it sure is nice to see some new visitors at a backyard feeding station. Here at the susquehannawildlife.net headquarters, American Robins have arrived to partake of the offerings.
American Robins feed on peanut hearts and chopped apples.
For this flock of robins, which numbered in excess of 150 individuals, the contents of this tray were a mere garnish to the meal that would sustain them through 72 hours of stormy weather. The main course was the supply of ripe berries on shrubs and trees in the headquarters garden.
Their first choice—the bright red fruits of the Common Winterberry.

After cleaning off the winterberry shrubs, other fruits became part of the three-day-long feast.

This European shrub is often distributed for conservation plantings as Highbush Cranberry, a common name shared with the very similar native species Viburnum trilobum.The blue-gray berries of junipers are attractive to robins, waxwings, and bluebirds.The American Holly (Ilex opaca) is a favorite of berry-loving birds. Its evergreen foliage provides cover and roosting sites for wintering birds.
Wouldn’t it be great to see these colorful birds in your garden each winter? You can, you know. Won’t you consider adding plantings of native trees and shrubs to your property this spring? Here at the susquehannawildlife.com headquarters we mow no lawn; the lawn is gone. Mixing evergreens and fruit-producing shrubs with native warm-season grasses and flowering plants has created a wildlife oasis absent of that dirty habit of mowing and blowing.
You can find many of the plants seen here at your local garden center. Take a chunk out of your lawn by paying them a visit this spring.
Want a great deal? Many of the County Conservation District offices in the lower Susquehanna region are having their annual spring tree sales right now. Over the years, we obtained many of our evergreens and berry-producing shrubs from these sales for less than two dollars each. At that price you can blanket that stream bank or wet spot in the yard with winterberries and mow it no more! The deadlines for orders are quickly approaching, so act today—literally, act today. Visit your County Conservation District’s website for details including selections, prices, order deadlines, and pickup dates and locations.
Evergreens like this Eastern Hemlock (Tsuga canadensis) are essential to the survival of many species of wintering birds. Plant evergreens in clumps, the bigger the better, to provide birds with thermal protection against the cold winds of winter nights.County Conservation District Tree Sales offer bare root evergreens like this Eastern White Pine (Pinus strobus) in packs of five or ten. Buy a bunch. Spend this year’s lawn treatment money on them. Then, get them planted immediately after pickup in the spring and in a few years you’ll have a nice grove of evergreens for wildlife habitat, a wind break, or a privacy screen.Groves of mixed evergreens among deciduous woods, grasslands, farmlands, or suburbs are ideal cover for wintering wildlife. These stands attract many species of migrating and nesting birds as well. Seen here, left to right, are Eastern White Pine, Norway Spruce (Picea abies), and Eastern Red Cedar. Though not a native species, the Norway Spruce is frequently used for conservation and ornamental plantings in the northeastern United States due to its appealing attributes and lack of invasive characteristics.Feeding wildlife is great fun. But remember, if you’re running a hotel for animals, you’ve got to offer more than an after-dinner mint to your tired and hungry guests. Let’s get planting!
