Remembering Nature Discovery Day

By Edie Parnum

For eight years I have been gardening for nature on my ¾-acre suburban property. My yard with its abundance of native plants teems with birds, butterflies, bees, beetles, moths, and other creatures both big and small.  On August 29 my property abounded with people, too.  I had invited nature-loving friends to enjoy my native plants and discover the creatures they support.

Some people came for just an hour, others stayed all day.  Most participated in one of the three guided yard tours.  The insect and pollinator walks were popular, too.  Kids enjoyed their own nature and insect events.  A sizable group drove to Barb Elliot’s nearby property and saw her pond and thriving native plant habitat.  Some truly nature-crazed individuals stayed after dark for moth night.

Unquestionably, the native plants were a hit. All the species were labeled for easy identification. Many of my favorite plants (Short-toothed Mountainmint, Grass-leafed Goldenrod, Upland Ironweed, Cardinal Flower, Great Blue Lobelia, Garden Phlox, Trumpet Vine, Trumpet Honeysuckle, Large-leafed Aster, and Sneezeweed) were in bloom. Berries on woody plants (Nannyberry and Blackhaw Viburnums, Flowering and Silky Dogwoods, Winterberry Holly, Black Chokeberry) and a vine (Virginia Creeper) were ripe and ready for the fall migrants.   (Click here for my complete yard plant list.)

Insects attracted notice and won new converts.  Many admired the Monarch and Black Swallowtail caterpillars.  The pollinators were active on the flowers.  We saw native bees (European Honey bees, too), wasps, flies, beetles, day-flying moths, as well as Ruby-throated Hummingbirds spreading pollen while feeding on the nectar.   Our entomologist, Dan Duran, PhD, identified a large blue-winged wasp (Scolia dubia) nectaring on mountainmint.  This wasp, a parasite on the larvae of Japanese Beetles, is now a favorite of mine.

The sharp-eyed kids on Debbie Beer’s nature walk saw a migrant American Redstart.  By turning over rocks and logs, they discovered slugs and other creepy-crawlies. They also found spiders (the wolf spider was popular), beetles, and a cicada shell—goodies the adults missed.

Vince Smith gave us a geology lesson.  My property is composed of Precambrian gneiss and schist, one of the oldest soils on the planet.  Because it’s well-drained, the Tulip Poplar, Black Gum, and various oaks I’ve planted will develop deep roots.   They should become massive trees and provide wildlife value for decades, perhaps centuries.

Usually I merely write about my yard’s plants and animals and post photos on the Backyards for Nature blog.  However, neither words nor pictures are enough.  Seeing the natural beauty of my yard and discovering the creatures living there is more powerful.

Many people told me they were inspired to create their own backyard ecosystems.  Others vowed a renewed commitment to enhance their developing habitats.

They said Nature Discovery Day was fun. I could see it on their smiling faces.

Edie’s Garden—A Place to Discover Nature

By Barb Elliot

Wildlife is abundant in Edie’s yard.  She finds birds, butterflies, moths, dragonflies, bugs,

beetles, bees, wasps, flies, and more – creatures she loves – living among her native plants.

It wasn’t always this way.  I saw the yard when Edie moved to this ¾-acre property in 2007. It was mostly turf grass. Except for a few native trees (Black Cherry, Red Maple, White Pine), no native plants grew here. Consequently, we observed few birds—just an occasional robin or starling—no other wildlife.  She knew she could transform her lifeless property into a healthy habitat for wildlife by reducing the lawn and planting native plants. It could become a place where she could discover, learn, and enjoy nature.

To create a healthy ecosystem on her property she wanted to:

  • Plant a diversity and multitude of native plants
  • Offer conditions for birds and other creatures to thrive and reproduce
  • Provide year-round food sources, water, cover, and places to raise young for wildlife
  • Welcome lots of birds—certainly hummingbirds
  • Create a place of beauty where she could be immersed in nature
  • Learn the species of flora and fauna and how they interact and depend on each other
  • Leave a legacy of nature for future generations with long-lived trees and shrubs

Gradually, year by year, she has succeeded in creating this haven for wildlife.  Eight years later I see thousands of native plants.  They include perennials, grasses, vines, ferns, and woody plants, i.e. shrubs and trees.  She planted densely, letting the plants touch each other as they do in the wild.  Her canopy trees are young, but the oaks and others will be massively productive for wildlife for decades.  Eastern Redbud, Flowering Dogwood, and Shadbush are already filling the understory.  The mature shrubs like Spicebush, Elderberry, and several viburnum species are now luxuriant.  At the ground

level perennials, vines, ferns, sedges, and grasses, are profuse. This diversity of plants offer nuts, seeds, berries, nectar, and pollen.  Even the foliage of the native plants is indirectly a source of food.  Insects eat the leaves and become food for birds and other creatures.

Birds now find what they need to live and thrive. They eat the fruits, nuts, seeds, and nectar produced by the yard’s native plants.  Resident and migrating birds eat the insects hosted by her native plants. For example, Carolina

 

Chickadees can locate the 6, 000-plus caterpillars required to feed their young.  Of course, no pesticides are ever used.

Edie has added other features for birds.  She installed nest boxes for cavity-nesting House Wrens and Tree Swallows.  She allows fallen leaves to lie in many places. Eastern Towhees and Brown Thrashers rummage in this leaf litter to find insects. Carolina Wrens

often locate their insect delicacies in the brush pile. On a snag (dead tree) woodpeckers, including a Pileated Woodpecker, forage for insects in the decaying wood. A Trumpet Vine grows on this snag and attracts hummingbirds seeking nectar from its flowers. A bird bath and small pond offer birds water. The bird feeders supply a small proportion of food needed by some of the birds. Many, many birds (106 species) love this yard.

Her meadow, in my opinion, is the crown jewel of her property.  It is chock full of colorful perennials and grasses.  Birds forage for seeds in late summer, fall, and winter. Numerous butterflies (30 species so far), bees, beetles, and other pollinators are active on flowers

blooming from April through October.  Even at night the meadow is alive with moths, beetles, and other insects and spiders.  Aiming a flashlight into the dense meadow plants, she can see the tiny, shining eyes of moths and other insects.  Bumble bees, too, sleep on the flower heads, resting for the next day’s work.

Edie has created a paradise for herself as well as the creatures that call her yard home. With binoculars and camera, she frequently takes nature walks around the yard.  The birds, whether eating, preening, feeding young, are always interesting.  Mating foxes are less expected.  Mating Garter Snakes, too. Even

better, she loves to discover a caterpillar eating leaves. When she locates other tiny creatures—bees, beetles, wasps, and others—she takes their photos.  At night she uses lights to attract moths.  She photographs these creatures, too.

Using the photos of insects, she can usually make identifications and then figure out their role in this ecosystem. What plants do they depend on?  What plants depend on them? What do they eat?  Who eats them?  Are they parasites?  Predators?

The possibilities for discovery are endless.  Mostly, she revels in success of the healthy ecosystem she has created.

Nature Discovery Day, August 29, 2015

Edie enjoys showing her garden with its native plants, birds, butterflies, moths and other creatures to nature-loving friends. On August 29th she will host Nature Discovery Day.  Throughout the day you can explore her yard, discover nature in action, and learn about habitat gardening. Guided walks for children and adults will be offered, too.  In the evening it’ll be Moth Night.

This event will be for a limited audience by invitation only. She’s inviting Backyards for Nature blog readers and their interested family and friends.  Save the date and watch for an invitation coming to you in late July or early August.

Looking for Nests

By Edie Parnum

Nests are hard to find.  Sure, it’s easy to see the House Wrens and Tree Swallows come and go from the nest boxes I have provided.  Most songbirds, however, build and raise

their young in well-concealed cup nests.  Paying particular attention to the dense areas, I examine my trees and shrubs. I look, too, for lumps in the crotches of trees. I strain to see high in the canopy.  The breeding season is well underway, but I’ve found only two cup nests on my ¾-acre property.

Early this spring a female Robin built a nest out of grass, sticks, and mud in a dense holly below my raised deck.  I could look down and see her settled in the nest. Once I glimpsed four pale aqua eggs. Here was an opportunity to learn more about the nesting behaviors of the American Robin. From a comfortable but hidden vantage, I planned to observe the mother robin incubate her eggs, then watch both parents feed the nestlings.  Not so. One day the female and the eggs were gone.

Plenty of predators prowl around my yard.  A ravenous jay, crow, raccoon, possum, snake, or even chipmunk might have devoured the eggs and destroyed the nest. Last year Gray Catbirds screeched hysterically when a Blue Jay ate their eggs.

Besides the Robin’s, a Mourning Dove’s nest was high in my in my crabapple tree this spring.  While my nature-loving arborist was removing winter-damaged limbs, he exposed a flimsy nest with two eggs in the crevice of a broken branch.  He left it undisturbed.   From the ground I could glimpse a Mourning Dove’s eye peering at me from above the

limb.  Again, I hoped to watch and study the birds’ breeding routine.  After a few days of viewing the brooding dove, however, I could no longer see the bird nor any activity.  Why did the nest fail?  Perhaps the arborist’s intrusive activity caused delayed nest abandonment.  Of course, a predator could easily have seen and raided the exposed nest. Thankfully, both the doves and robins will nest again—successfully, I hope.

Besides searching for nests, I’m also watching for signs of breeding.  Catbirds, cardinals, house finches, song sparrows must be breeding here. Pairs of birds, singing loudly and persistently, cavort in my yard.  Some birds carry nest material.  Others have insects in their beaks. When they don’t eat the food, they’re carrying it to a nest—a sure sign of breeding. I hope to discover the nest where nestlings are being fed.

Though I have not seen it, I believe a pair of Brown Thrashers has a nest on my property.  Most suburban yards don’t host Brown Thrashers, especially not a breeding pair.  Thrashers like dense shrubbery, not the typical manicured landscape. With their bills they sweep and probe the ground searching for insects and spiders in last year’s fallen leaves. I was plenty pleased when a Brown Thrasher spent the winter in my yard.  This reddish-brown, jay-sized bird with a streaked belly stayed silent and sheltered in the arborvitae and other dense vegetation. Every few days I saw it stray from its hiding place and feed on exposed ground.  I assumed it would move on in the spring to breed elsewhere.

In mid-May, a Brown Thrasher, possibly the same bird, sang vociferously from the treetops.  Its loud doubled phrases are different from its close relative, the smaller Northern Mockingbird.  The purpose of the song is to attract a mate and defend a breeding territory.  Even so, I assumed my wintering bird (or new arrival) was just practicing and would not stay to breed here.  When the singing stopped a week later, I concluded it had departed.

To my surprise in late May and June I’ve occasionally glimpsed a soundless thrasher. Males and females are indistinguishable, but sporadically I have seen two birds together.  Could a pair be breeding after all? The thicket of forsythia and blackberries at the back of my property is perfect for thrashers. Every few days I spend a few minutes peering into the undergrowth and listening.   Once I saw it deep, deep inside the dense vegetation.  On another occasion I discerned a barely audible whisper version of the thrasher song. According to my research, thrashers are mostly silent during the nesting season but sing softly in the vicinity of a nest.

Surely thrashers have a nest in my shrubbery.  It is probably just a few feet off the ground, but hidden in the impenetrable thicket. My chances of discovering it are slim.  Because they consider me a potential predator, the birds probably engage in evasive behavior to lead me astray.  Undeterred, I keep looking and listening.

I need a vigilant, alert ornithology student to help find the nest. A sharp-eyed young person could spot the bug in the thrasher’s beak.  Together we could find the nest.  See the baby birds. Watch their parents put insects into gaping mouths.  Observe the naked babies grow pinfeathers followed by juvenile feathers.  We would thrill to witness them fledge and take flight into the world of my backyard.  Alas, without my student, I evidently can’t be a voyeur of birds’ private lives.

By searching for nests, I’ve learned more about helping breeding birds succeed. I’ll plant more dense shrubs where birds can build and protect their nests. These shrubs will be insect-hosting natives instead of the non-native forsythia. Already I do not tidy up the thickets and corners of the yard.  Thrashers and other ground-feeding birds require the leaf litter to feed themselves and their offspring. Next fall I’ll welcome leaves into the perennial beds, too. And, most important, I’ll grow more native plants where birds can find plentiful insects to feed their young.

In some ways I’m unable to help and must trust the birds’ own survival abilities.  Predators abound, but the birds possess skills to protect their nests, eggs, and nestlings.  Vigilant and ingenious, they know how to keep their nest locations secret.  Thankfully, when a nest fails, most are able to produce a second brood.

It’s summer now, and I see lots of baby birds around the yard.  The nests are somewhere nearby. Birds are breeding here successfully.

 

Prime Plants for Nature: Backyards for Nature 2014 Native Plant Awards

By Edie Parnum

Each year we select two native plants with exceptional ability to support wildlife. These plants will contribute significantly to the web of life in your yard. They host insects, offer nectar and pollen, and produce fruits, seeds, or nuts. Birds, butterflies, and other insects and animals will feed and prosper.  Most provide shelter and nesting places, too.  Our selections, all native to southeastern Pennsylvania, are easy to grow and readily available at native plant nurseries or native plant sales. Our Prime Plants make attractive additions to your landscape.  We offer awards in two categories: Trees and Shrubs and Perennials.

Our selections for the 2014 Prime Plants for Nature Awards are:

Eastern Red Cedar, Juniperus virginiana                                                     

Wildlife Value: This small evergreen tree is a powerhouse for nature.  Yellow-rumped

Warbler, Eastern Bluebird, and Northern Mockingbird are among the 54 species of birds that eat its long-persisting berry-like cones during the cold months.  Cedar Waxwings areso-named because they’re fond of cedar cones. The foliage hosts the Juniper Hairstreak butterfly, a vulnerable species in Pennsylvania, and several species of moths such as the Curve-lined Angle.  Song Sparrows and other

birds use the dense foliage for nesting places and shelter. Don’t be tempted to buy the similar-looking Leyland Cypress, a non-native that offers little for wildlife.

Growing Conditions: The Eastern Red Cedar tolerates a wide variety of soils and dry to moist growing conditions.  It prefers a sunny spot. These trees are either male or female.  Only the female trees produce fruits, but you’ll also need a male for pollination.

By planting at least three of these trees, you will enhance their wildlife value.    A row of cedars will provide dense shelter for birds. From the human perspective, the cedars can offer privacy. If planted on the north side of your house, they will create a windscreen.

Appearance: This evergreen has a pleasing conical shape.  It grows at a moderate rate (1-2 feet per year) and reaches 15-40 feet at maturity.

Short-toothed Mountain Mint, Pycnanthemum muticum

Wildlife Value: This perennial is a magnet for pollinators.  Butterflies, bees, wasps, and flies are attracted to the copious nectar and pollen this lovely plant produces.  Because it

flowers over a long period of time, it may host thousands of visits by pollinators each season.  With this plant in your yard, you can introduce children to pollination and teach them not to be afraid of bees and wasps.

Growing Conditions: Mountain Mint is a tough plant and will grow well in dry to moist soil in full to part-sun. Like other members of the mint family, it spreads but can easily be controlled, especially early in the growing season. It’s easy to transplant and share with other native plant gardeners.  This perennial is deer-resistant, too.

Appearance:  Mountain Mint grows to about 3-feet tall.  Although the numerous flowers are small and inconspicuous, the foliage is an attractive silvery grey.  The leaves complement other brightly colored flowers in the garden and in flower arrangements, too. This plant’s attractiveness is enhanced by the beautiful butterflies and other pollinating insects that visit.

Resolutions to Bring Nature to Your Yard in 2014

By Edie Parnum

Oh, no, you say.  I never make resolutions—too much self-denial and discipline.

Here are some resolutions that don’t require much work.  And, in fact, they’ll add pleasure to your life. Pick one of these to get started. Birds, butterflies, and other creatures will visit your yard.  Pick three, and you’ll see nature flourish abundantly–guaranteed.

  1. Plant a tree.  Adding a native (historically part of our local ecosystem and food web) tree is the single best contribution you can make to your property’s habitat.  It will offer more food, shelter, and nesting places than any other plant.  Besides providing seeds, fruits, or nuts directly to birds and other animals, the tree’s leaves host native insects.  Birds and other small animals eat native insects in

    large quantities. The small animals are prey to larger ones.  Thus, this native tree and its insects contribute enormously to fuel your yard’s ecosystem.  It’s easy and inexpensive to plant a sapling tree.  It will establish quickly, grow fast, and sustain wildlife for decades.  Surely you have room for one tree (small or large), perhaps several of them.  Native oaks offer the best wildlife value but check our website for other valuable native trees.

  2. Plant shrubs.  Requiring less space than a tree, they offer nearly as much value to a healthy habitat. Besides the nutritious fruits these woody plants produce, insects eat their leaves.  As with trees, these insects sustain birds and the other animals in the web of life.  Also, dense deciduous and evergreen shrubs provide

    cover and places for nesting birds.  Highbush Blueberry (Vaccinium corymbosum), Red and Black Chokeberry (Aronia sp.), Northern Bayberry (Morella pensylvanica), and various native dogwoods (Cornus sp.) and viburnums (Viburnum sp.) are excellent choices. Plant three or more of each species.  See our website for recommended shrubs.

  3. Plant perennials, not annuals.  Annual flowers are so much trouble to put in each year, fertilize, and keep watered.  Forget the bothersome begonias, impatiens, marigolds, coleus. petunias, and the like.  Native perennials will grow

    Hummingbirds, bees, butterflies, and other pollinators feed on Wild Bergamot’s nectar.

    and bloom beautifully for years without any extra care. My favorites are Butterfly Weed (Asclepias tuberosa), Summer Phlox (Phlox paniculata), New England Aster (Symphyotrichum novae-angelae), Bee Balm (Monarda didyma), and Mountain Mint (Pycnanthemum muticum), but there are many other beautiful native perennials. All provide nectar and pollen for bees, butterflies, and other pollinators. Like other native plants, they host native insects, too.

  4. Plant a vine.  If you want hummingbirds in your yard, plant a Trumpet Honeysuckle (Lonicera sempervirens) (not the invasive Japanese Honeysuckle, of course) or Trumpet Vine (Campsis radicans).  Virgin’s Bower (Clematis virginiana) is a magnet for bees, moths, and other pollinators.
  5. Plant groundcovers.  Minimize weeding.  Instead, cover the ground with native groundcovers like Allegheny Pachysandra (Pachysandra procumbens), Green and Gold (Chrysogonum virginianum), and Golden Ragwort (Packera aurea).
  6. Take out a patch of lawn.   It’s the most biologically deficient part of your yard—not much better than your driveway.  Every year decrease the size of your lawn
    Great-spangled Fritillary nectaring on False Sunflower.  Click to enlarge.

    Great-spangled Fritillary nectaring on False Sunflower.

    and keep only what you use for family activities, dog play, and other outdoor activities.  Instead of turf grass, plant any and all of the above: trees, shrubs, perennials, vines, groundcovers.

  7. Take out invasives.  Invasive plants spread aggressively and crowd out desirable native vegetation.  Yes, whether you cut, pull, or smother the invasives, it can be a lot of work.  Plus, if you leave the ground bare afterward, of course they’ll come back.  Immediately fill in the cleared area with native plants.
  8. Learn native plants.  You can attend botany walks at Bowman’s Hill Wildflower Preserve, Heinz National Wildlife Refuge, and Tyler Arboretum.  Visit a botanical preserve where native plants are labeled such as Bowman’s Hill and Jenkins Arboretum. When buying plants at native plant nurseries like Redbud Nursery and Yellow Springs Farm, you’ll see labelled plants and learn growing tips from their knowledgeable staffs.  Use the internet photos and gardening information, too.
  9. Read a book.  I recommend Bringing Nature Home: How You Can Sustain Wildlife with Native Plants.  The author, Douglas Tallamy, professor and chair of the Department of Entomology and Wildlife Ecology at the University of Delaware, will inspire you to plant native plants and increase your determination to host native insects, birds, and butterflies in your yard.

  10. Walk around and enjoy nature in your yard frequently.  Take your binoculars to better see and learn about the birds, butterflies, and other creatures that live in your garden.  With a camera you can take photos of your plants and wildlife sightings.   You’ll be inspired to become more familiar with your own wildlife preserve. Spread your enthusiasm: take a child with you on your backyard adventures.

Personally I will do all ten of these—with pleasure.

If you’re a beginner to habitat gardening, pick one of these ideas to get started.  Perhaps you can tackle two or three this year, but don’t get overly ambitious.  Start planning now in the dead of winter. Time and money may be limited, but you can start small and keep improving your habitat each year.  Before long you’ll notice more insects including butterflies and moths, more birds, and, indeed, much more wildlife activity in your yard.

Do something for nature in 2014.

 

Native Berries for Fall Migrants

By Edie Parnum

Birds were dropping out of the sky into the trees and shrubs around me. It was daybreak on a fall morning in my backyard.  Though I could see only silhouettes, I recognized the chips of robins and Swainson’s Thrushes.  In the dim light I couldn’t identify the other numerous birds but knew these were migrants that had flown non-stop from the north during the night.

After their nighttime exertion, they were exhausted and ravenously hungry. They needed to find high-energy food and to revive in a habitat offering shelter from predators.  With most of the surrounding area covered with buildings, roads, parking

lots, and sterile lawns, they were desperate for sustenance.  From above, the migrants probably see the local parks as deceptively inviting, but the grass and other non-native vegetation provide little nutritious food.  Their energy depleted, these migrants need familiar and nourishing native plant food.  Otherwise they are in trouble.

Watching these migrants, I imagine myself on a road trip, one I’ve done many times.  After hours of driving, I’m hungry, tired, and low on gas.  I’m looking forward to Rosie’s Restaurant, a favorite stop for good food, gas, and a respite from the journey.  To my dismay, the restaurant and adjacent gas station are gone.  Wasting time and energy, I must drive around randomly to locate what I need before resuming my trip.

Migrants often find my yard and use it to rest and refuel.  During fall migration, especially after a cold front, I search for recent arrivals.  Sometimes I find thrushes, tanagers, grosbeaks, and warblers eating berries on the Virginia Creeper, Arrowwood Viburnum, Winterberry Holly, Spicebush, Black Chokeberry, Flowering Dogwood, Crabapple, and Northern Bayberry I’ve planted for them. One winter a southbound Hermit Thrush stayed in my yard all winter eating American Holly berries.

This fall I’ve been watching a Gray Catbird eating berries on the Virginia Creeper

hanging above my deck railing.  Because the bird is just a few feet away, I don’t really need my binoculars.  It lands on a branch, leans forward, grabs one of the blue-black berries, then quickly swallows—again and again, all day long.  Either a resident breeder soon to migrate or a recent arrival using my yard as a stopover, this bird needs these berries. Besides Gray Catbird I’ve seen Red-bellied Woodpecker, Northern Flicker, Brown Thrasher, Cedar Waxwing, Eastern Bluebird, Swainson’s Thrush, American Robin, Cape May Warbler, and Yellow-rumped Warbler eating Virginia Creeper berries.

Prior to migration, songbirds must increase their weight by 50-100%.  Thrushes, grosbeaks, waxwings, orioles, tanagers, and other songbirds switch from a diet of insects to mostly berries.  Finding berries consumes less energy than pursuing insects.  Scott McWilliams and Navindra Seeram, researchers at the University of Rhode Island, are studying the diet of birds preparing for migration on Block Island.  According to this new research, birds select deeply-pigmented berries

that are high in antioxidants and fat prior to migration.  Antioxidants help birds(as well as humans) handle stress.  Because migration is certainly stressful, birds need to find nutrient-rich berries at stopovers along their migratory routes.

Migration is hazardous for birds.  On their southward journey they fly at night for four to six hours without a break. They must stop and refuel several times before reaching their wintering grounds, especially if their final destination is the tropics.  They spend four to five days at each stopover where most consume nutrient-rich berries.  If they fail to find sufficient fuel for the next leg of their journey, they become weak and vulnerable to hawks, owls, and other predators.

Scientists tell us even small patches of native plants can provide food and shelter for migrating birds.  On my three quarter acre property, I’ve planted scores of fruit-bearing native shrubs, trees, and vines.  Besides the shrubs mentioned, I’ve recently planted Black Gum, Hackberry, Sassafras, and Spicebush that will offer fruits in future autumns.  Also, in a few spots I allow Pokeweed (regrettably considered a weed by most gardeners) to grow and produce beautiful dark purple berries irresistible to birds.

Since many ornamental and invasive non-native plants produce berries, why are native plants so important for migrating birds?  With their high fat content and extra antioxidants, native berries are highly nutritious.  Because the natives usually have

strongly-colored berries, either black or red, or have leaves or stems that are bright red, birds can easily find them.  Also, the native berries ripen at the right time.  Many migrants, especially warblers, continue to eat insects as well—found primarily on native plants.  If necessary, of course, birds will also eat the less nutritious fruits of non-native plants.

Most yards have room for shrubs.  You can plant native fruit-bearing shrubs and small trees around your property’s perimeter to create a hedgerow laden with nutritious fall fruits.  You can also group them around isolated trees.  By reducing your lawn, you’ll find room for more shrubs and other fruiting plants.

Birds, especially those that migrate to the tropics, are in trouble.  On average, the populations of long-distance migrant species drop 1% each year. We assume we can do little except give money to organizations that preserve land.  However, we can help migrating birds survive their perilous and crucial journeys by growing the plants they need and love.

Fall: Time for Planting Trees and Shrubs

By Edie Parnum

I thrust my spade into a patch of my lawn.  It’s fall, and I’m planting a 4-foot Chestnut Oak.  As I dig, I imagine this young tree next spring with its new green leaves.  Even as a young sapling, it will host insects and birds.  Looking into the future, I imagine this stately native tree a century from now.  It has given life to thousands of birds and other animals.

My neighbors, I’ve noticed, aren’t thinking about spring.  They are clearing their yards of leaves and the dead vegetation from last year’s ornamental plants.  They are putting this unwanted garden debris out on the curb along with the cocoons and eggs of next year’s insects. They are getting ready for winter. Fall is the best time for planting trees and shrubs, any time before the ground freezes. During the autumn rains, the new plants aren’t asleep. They’re putting energy into their roots for a spurt of growth next spring.This fall, as usual, I will plant several trees and shrubs.  When I bought this ¾-acre property five years ago, it was mostly grass with just a few trees, mostly non-natives.  Since then I’ve planted 39 native trees and 45 native shrubs. It’s still not enough.

I keep planting native woody plants because they support wildlife.  Certainly non-native woodies offer fruits birds will eat—witness the bird-spread proliferation of invasives like Multiflora Rose, Burning Bush, and Japanese Barberry.  Natives, however, offer fruits of optimum size and superior nutrition. The fruits of the dogwoods, blueberries, winterberries, viburnums, spicebush, and sassafras I’ve planted ripen just in time to nourish hungry migrating birds in fall. Now in late October most of the berries are gone—consumed by thrushes, catbirds, mockingbirds, waxwings, and warblers.

The main reason I plant native woodies, however, is for the caterpillars and other insects these plants support.  I’m inspired by Doug Tallamy, Professor and Chair of Entomology and Wildlife Ecology at the University of Delaware.  His research shows

that native plants host 29 times more of the native insects essential for our birds. After all, 96% of terrestrial birds feed their young exclusively insect food.

This year to augment what I’m already growing, I’ll plant ten small trees and shrubs.  I’m planting the Chestnut Oak, Quercus prinus (according to Tallamy, oaks host 534 species of caterpillars); American Elm, Ulmus Americana (hosts 213); and Pawpaw, Asimina triloba (host plant for Zebra Swallowtail butterfly, a species I covet for my yard butterfly list).

Planting a tree or shrub is easy.  For my Chestnut Oak and the other trees and shrubs, I don’t need to dig a huge hole.  I make my hole only as deep as the soil in the plant container and twice as wide.  After putting the plant into the hole, I make sure the soil line of the plant is level with the ground. Then I use the soil that was removed from the hole to fill in around the plant.  Because my oak is a local native adapted to our soil, I am not tempted to add special topsoil, fertilizer, or any other enrichment.  That would stimulate fast but weak growth.   A hole filled with artificially enriched soil encourages the roots to stay confined rather than to reach into the ground below for nourishment.  Next, I push down on the loose dirt with my hands, but avoid stomping on it with my feet.   I spread a one-inch layer of my compost (last year’s leaves and garden debris) on top to provide some extra humus not available in the turf grass.  Then I give my oak a good watering.  That’s it for this tree.  I’m ready to plant more.

Newly planted trees and shrubs may need extra water.  During any week without significant rain, I put a leaky watering can next to each plant and let the water drip slowly into the soil.  A 1-2” layer of mulch will help retain the moisture, but I never let the mulch touch the trunk.  Once established, these woody plants, situated appropriately for light and moisture, should thrive without any additional help from me.

The trees and shrubs I plant are usually small.  They are cheaper and suffer less transplant shock than a big tree or shrub.  These smaller saplings start to grow more quickly and in a few years usually out-compete larger nursery stock.  To save money, I also frequently transplant volunteer trees and shrubs in my yard to more appropriate locations.  Some of my shrubs—virburnums, for instance—send out shoots that I dig up and plant elsewhere.  I also accept gifts from my native plant gardening friends.  As I say, there’s always room for more.  Anyway, I’m not growing ornamental specimens.  The plants can touch each other and offer extra shelter, just as they do in the wild.

My trees and shrubs are still small, but they already support birds and other wildlife.   Next spring I’ll see warblers and other hungry migrants eating caterpillars on the leaves of my native woody plants.  The remaining areas of grass are begging to be planted with additional native trees and shrubs.  Next fall I won’t resist planting more.

Create a Living Legacy: Plant an Oak

By Edie Parnum

dd

Planting an oak is the single most important thing we can do to support wildlife.

As a birder who loves spring migration, I have long noticed that my beloved warblers and other colorful birds prefer the native oak trees.   On May mornings, just when their foliage is emerging, I scan the oaks.  That’s where I find American Redstarts, Blackburnian Warblers, Scarlet Tanagers and other favorites in their resplendent spring plumage.  Only recently have I learned why these birds are in the oaks.  I credit Doug Tallamy, Professor of Entomology at the University of Delaware and author of Bringing Nature Home.  Oaks, according to Tallamy, support 534 species of lepidoptera (butterfly and moth) caterpillars– more than any other native tree or plant. These caterpillars are not only the primary food source for migrating and breeding birds, but are essential food for baby birds. Other native plants support caterpillars, too, but non-native plants host very few at all.

I’ve always known that acorns are important food for turkeys, woodpeckers, jays, nuthatches, squirrels, chipmunks and other animals.  However, birds and other animals are even more dependent on the insects that munch on the oak leaves.  According to Tallamy, in addition to myriad lepidoptera species, oaks host aphids, leafhoppers, thrips, and other bugs–all target foods for animals throughout each growing season.

Professional landscapers may try to dissuade you from planting an oak.  They’ll tell you it grows too big for the average-sized yard, though most yards are big enough to support a full-sized mature oak.

Perhaps, without any sense of irony, they will say that an oak will grow too slowly.  Certainly most oaks will be small for many years, but even young trees will support lots of insects.

While there are many local, native oaks to choose from, the handsome White Oak (Quercus alba) is my personal favorite.  From my childhood days in Salem County, NJ, I have fond memories of a nearby magnificent, ancient White Oak.  John Fenwick, an early settler, signed a treaty with the Lenape Indians in 1676 under this tree, now approximately 425 years old.  This species grows slowly (about a foot per year), but can live for centuries.

Other recommended oak species include Scarlet Oak (Q. coccinea),  Chestnut Oak (Q. montana),  RedOak (Q. rubra), and Black Oak (Q. velutina). These oaks are available at native plant nurseries and native plants sales. Since oaks have long tap roots, choose a small specimen (4’ or less) or grow your own from an acorn.  Because they are adapted to our soils and climate, no fertilizer or other amendments are needed.  However, regular watering during the first year helps the root system get established.

An oak is your personal legacy.  Your oak can live for centuries. It will host an inestimable number of birds, insects, and other wildlife during your own lifetime and for generations to come.
