Landscaping with Nature

In the winter, as you drive across the American Legion Bridge or across many of our creeks, you may be startled to see large numbers of trees with bright white trunks and branches. You may worry that climate change has struck and left them bleached. Worry no more: those are American Sycamore trees, sometimes known as the Ghosts of the Woods, whose bark normally peels as the trees get taller, leaving a white and brown pattern that shows best once the leaves have fallen. These congregations of sycamores help us notice that our seventy or so locally native tree species are not randomly distributed throughout the woods but rather are living in natural plant communities. As our region ramps up the Plant NOVA Trees campaign, understanding natural communities can help us design our landscaped environments to better support our local ecosystem.

Sycamores and other trees that live in wet soil can survive there because their roots can tolerate low oxygen conditions. They don’t necessarily need a lot of water and can thrive in the low oxygen conditions of many of our dry, compacted lawns. Unlike non-natives, these native trees will provide food for vast numbers of caterpillars and thus for the birds and other critters that eat insects. The contributions of native trees to the food web, combined with the increasing numbers of beautiful species available for sale, are why they are the default choice in all but the harshest of our built environments. Planting any native tree is a very good way to contribute to our region’s effort to expand the tree canopy.

Having said that, though, is it possible for us to do even better by taking plant communities into account? Again, trees are not randomly distributed in the woods, and neither are the birds and other critters that depend on combinations of specific plants. It is not within our power to fully restore the ecosystems which we have destroyed, but we might at least nudge them in the right direction by grouping plant species that would naturally live together on the terrain we have occupied.

If your yard has wet or compacted soil, an American Sycamore could be a great choice. But what if you live on a dry hillside and your soil is not compacted? In that case, you might prefer to choose trees and accompanying understory plants that are more representative of a hillside natural community. For example, Mockernut Hickory, Flowering Dogwood and Maple-leafed Viburnum underplanted with Virginia Creeper and Blue-Stemmed Goldenrod would give you the start of an Acidic Oak-Hickory Forest, a very common plant community around here.

Dozens of plant communities have been identified in Northern Virginia, but only a few of them are very common. How can you tell which is most appropriate for your property? This is no easy task, even for experts, not only because it is highly technical but because humans have altered the landscape in many places beyond recognition. However, you might be able to make a reasonable guess based on the elevation of your yard in relation to the nearest creek. You can then look at a plant list for the relevant community and decide which ones you might like to add to your property, given its current light, soil and moisture conditions. Just as in nature, as your trees grow and shade out the understory, sun loving plants will give way to shade tolerant ones, providing future residents with a haven from the heat, far more useful than a sun-scorched lawn in this warming world.

Details about the plant community concept (and about how you can find someone to help you implement it) can be found on the Plant NOVA Natives website. Even if you have no planting plans, if you have a passing familiarity with our native trees and other plants, reading about our natural communities can add to your pleasure as you walk through our woods and notice the patterns.

Review of Storm, by George R. Stewart

Review by FMN Kristina Lansing

When was the last time you read a “thumping good read” about nature? If it’s been awhile and if you’re looking for something to really sink your teeth into, do give George Stewart’s “Storm” a try. First published in 1941, this book is considered by some to be one of the first eco-novels ever written. Roughly a decade after its publication — and influenced by its publication — the National Weather Service began naming all major storms.

The protagonist in Stewart’s narrative is Maria (pronounced “Ma-rye-a”), the storm herself, “born of a dalliance between northern and southern air off the coast of Japan. After a rapid gestation, she quickly begins to grow, devouring atmosphere.” A junior meteorologist at the Weather Bureau names her, then watches as “the baby eats and sleeps and makes babbling noises. But [she] does not stay cute for long and soon grows teeth. By the time she debuts on the Pacific Coast, she has left her youth behind.”* This captivating description in the Introduction aside, the book is deeply rooted in science.

People and organizations of course figure prominently in this book, and their stories rival the tale of the storm herself. For animal lovers, even an owl, a hog, and a coyote play important roles. “Storm” is a tale of dispassionate natural forces and of cause-and-effect. It’s also a tale of efficiency, of leadership and teamwork, of bravery, and of humanity.

In writing this novel, George Stewart collaborated with at least 15 organizations, to which the book is dedicated: he became a storm chaser; he rode locomotives, flatcars, even an engine snowplow. If you decide to read this splendid book, do try to crack it open on the eve of a big, local storm. Just make sure you have extra batteries for your flashlight in case the electricity goes out! The book’s not long, just under 300 pages.

George Stewart received his PhD in English literature from Columbia in 1922 and joined the English faculty at the University of California, Berkeley, in 1924. He was a sociologist, toponymist, and founding member of the American Name Society, and he wrote over 20 books.

Public-Private Partnership Leads to a Greener Springfield District

A pilot project on Arley Street in Springfield is an environmental success story. With significant community initiative and modest government assistance, 4,300 square feet of asphalt in the Springfield district was converted back to green space.

Community property within the Springfield Station Homeowners Association (HOA) included a deteriorated basketball court which was at the end of its lifecycle and no longer provided a useful benefit to the community. During planning for the community space, residents decided to remove the basketball court entirely. The HOA applied to the Northern Virginia Soil and Water Conservation District’s (NVSWCD) Conservation Assistance Program (CAP) for cost-share funding and technical assistance for the proposed conversion of the basketball court to green, open space. The community space is entirely within the Resource Protection Area (RPA) of an unnamed tributary of Middle Run (Pohick Creek) and eventually flows into the Potomac River. The community planned to remove the asphalt surface and reduce the compaction of the soil by adding at least two inches of topsoil and compost.  With this plan in mind, NVSWCD confirmed that the project was eligible for participation in CAP because it promotes infiltration, reduces the potential for nearby flooding, and improves stream health.

Through a newly established partnership between NVSWCD and Fairfax County’s Land Development Services (LDS), the project was able to receive the maximum possible cost-share amount eligible under the CAP. This partnership effectively created the new NVSWCD/LDS Water Quality Improvement Program (WQIP), whereby LDS allocates funding for eligible CAP projects with funds collected under LDS enforcement action, thus improving the environment within the impacted communities where violations previously occurred. The Springfield Station HOA project was the first recipient of funding from the newly launched partnership.

The public-private partnership is one that will be replicated throughout the county for other community association and places of worship projects approved under the CAP program. Thus the 4,300 square feet could represent the first step in projects that occur across the county, improving water quality in every district.

LDS project lead Brandy Mueller said, “Though small in terms of scale, this project was really a huge endeavor and a great benefit to the community. This new partnership seeks engagement and environmental opportunities. We hope this successful case study will encourage others to pursue similar projects.”

Replacing impervious asphalt (which does not allow water to pass through it) with green space results in multiple environmental benefits:

  • Fields absorb water, replenish the groundwater and slowly contribute to nearby streams whereas asphalt (or other impervious surfaces) divert rainwater to storm drains and sewers.
  • Fields allow the water to feed the soil supporting trees and other plants and resulting in healthier habitats for wildlife, insects and birds.
  • Fields are about 30 degrees cooler than asphalt helping cool down surrounding areas.

Review of Water: A Natural History, by Alice Outwater

Reviewed by FMN Kristina Watts

Water: A Natural History is not just about water. As naturalists, we understand that everything is connected. I teach my students that streams are like the veins and arteries of the Earth, transporting nutrients and wastes; and we all know that water is necessary for life. I picked this book up thinking it would focus on hydrology, chemistry, and provide some details on the water cycle that would be fun to share. But instead, it was deeper than that: it’s the story of relationship, of activities and consequence.

Using aquatic resources as common thread that ties it all together, Alice Outwater takes the reader on a journey through time, showing us how humans have impacted the region that is now the United States since before European discovery of the continent. Starting with the beavers and eventually wrapping her narrative around buffalo, prairie dogs, mollusks, and alligators, she emphasizes how plentiful the animals were that lived on this land throughout pre-colonized history and how their behaviors shaped the ecosystems around them. We talk a lot about keystone species and their role in food webs, but this book highlights the direct connection between animals and the shapes of streams and rivers, ground water recharge, and water quality. Then she describes how human activity has reduced the populations of animals (and plants), and the resulting effects. She takes us through the human side of each story too, explaining for example the demand for fur in Europe during the 1600s, farmers’ naïve understanding of soil structure in the grasslands, and the U.S. government’s endeavors to engineer rivers for transportation and electric power needs.

All of the changes she describes through water’s “natural history” paint a picture of loss – loss of diversity and ecosystem health. She ends with a chapter on wastewater treatment (her specialty, as an environmental engineer by profession) and hope inspired by relatively recent environmental laws (Clean Water Act, Clean Air Act, etc.). She indicates that balance can be restored, if only we allow nature to take its course, well, more naturally. This book was published in 1996; my only complaint about it is that it is “old” – almost as much time has again passed as since the 1970s statutes and when the book was written. I’d love to see an update.

At 224 pages, this book is a pretty fast, colorful read and provides long-term, holistic perspective as well as interesting stories to enhance any discussions you may have involving water resources and our impact on them.

By: Mary Jane Poulter, Central Piedmont Chapter and
Marilyn Parks, Fairfax Chapter

At the annual Virginia Master Naturalist conference this year, a favorite activity was the chat room. The chat room was a sub-area of the conference where attendees could start discussions on topics of interest. Since the conference was virtual, discussions could occur in real time or asynchronously.

Mary Jane had already been thinking about possibly writing an article for Central Piedmont about a naturalist’s toolkit – “What do you carry when you go out into the field?” Marilyn Parks reached out to Mary Jane via the chat room and said she had been collecting information and was also thinking of writing a “What’s in your backpack” article for the Fairfax Chapter!

The two shared emails and decided going forward with an article that should be less of a story and more of a list.

Here is the list that they developed. The items that you decide to pack in your knapsack will vary with the focus of the activity, with the environment where the activity is occurring, with the time of the year, and with the planned length of the activity. Sometimes you may only need a light knapsack and other times you may want a backpack. Whatever the plan is for the activity, you should always plan for the unexpected!

Party Time on the Disc Golf Course

Photo courtesy of Plant NOVA Natives

We don’t usually associate the native plant movement or a tree campaign with sports, but players at the Giles Run Disc Golf Course see it as a natural connection. Their course, about a third the size of a regular golf course, was created in 2008-2009 by the Fairfax County Park Authority on land that was formerly mowed grass around the Lorton Prison. Unfortunately, disturbed land with a lot of edge habitat is an invitation to invasive non-natives plants to move in, and move in they did with a vengeance after the prison closed in 2000. The Oriental Bittersweet vine has been particularly problematic, turning the areas next to the fairways into a tangled mess and swallowing up the native trees and shrubs as well as the players’ discs.

Most people would probably just expect someone else to fix the problem, but disc golfers turn out to be a different sort. Organizers Tommy Donelson and Kemper Pogue started recruiting players to participate in invasive removal parties, complete with music from a portable speaker. Forty or fifty club members have joined in this fun and free way to build upper body strength, clearing out large swathes of invasives. They have also recruited other volunteers to help, starting the sessions with half an hour of education before tackling the job. Altogether, they have been putting in a hundred hours in nine sessions every month, year round.

Oriental Bittersweet is a particularly troublesome plant when taken out of its native habitat in East Asia and imported elsewhere, as it was for its pretty red and yellow berries which are used for decorations. It twines around trees, strangling them and bringing them down. It curls itself into impenetrable thickets. When cut down, it simply regrows stems that can reach high up into trees to latch onto the branches and keep going up from there. Eliminating it requires either pulling it up by its roots, some of which can be several inches thick, or using herbicides.

It did not take long for the disc golfers to understand that the invasives issue on their course is just one example of a much greater threat to our ecosystem in Fairfax County and the world in general. They are planning to eventually replant with native plants and have been spreading the word about how important it is for residents to take out invasive ornamentals from their own yards and use more natives to support the struggling ecosystem. Information about garden-friendly native plants can be found on the Plant NOVA Natives website. Meanwhile, they would be happy to invite others to their work parties. They can be contacted at [email protected]. There are plenty of opportunities in other parks as well to help with invasive removal. Cold weather (within reason) is no obstacle, since this is warm work.

Alexandria Neighbors Bring Trees to Their Community

Photo:  Plant NOVA Natives

Trees plant themselves and replace themselves – except in our lawns. Many Northern Virginia neighborhoods that are graced by magnificent mature trees are now slowly losing their canopy as those trees die from old age or disease (or are cut down while still healthy by humans.) Each lost tree means higher temperatures and air conditioning costs on that property, more stormwater runoff, and in the case of native trees, the loss of a home and food supply to thousands of our smallest neighbors including caterpillars and songbirds.

City of Alexandria residents Lynn Gas and Jane Seward were bemoaning the fact that their neighborhood of over 30 years was so much hotter than it used to be due to the loss of tree canopy. They decided to do something about it and started the Canopy Tree Restoration Campaign. After educating themselves about trees, they talked to their neighbors and got each to sign up to have a tree installed at a deep discount. They helped each homeowner select and mark the site. They then contracted with a landscape company to install all the trees on the same day. Each of the selected tree species was indigenous to the area and thus able to contribute to the local ecosystem. They planted 140 trees that first year.

The campaign has been a labor of love for Lynn and Jane, who have learned a lot in the process. Since the project began in 2017, they have planted around 280 trees. They often send out emails to remind people to water, since landscaper-sized trees must be watered regularly until they get established, a process that takes two or three years. They have used different nurseries and landscapers, trying to find the best trees at the best prices. It took a while to understand how nurseries work and to identify landscapers that know how to properly plant trees and are willing to give a good price. It is important when planting in many different yards to organize the planting so that landscapers can plant fast without losing time on logistics. They need to make money, so Lynn and Jane think of their coordination efforts as facilitating their work.

Lynn and Jane do not describe their initiative as selling trees. Rather, they ask people to participate in the neighborhood reforestation campaign, using phrases such as “A tree in your yard benefits all of us.” They also have received generous donations which allow them to donate trees to churches, playgrounds and schools as well as to neighbors lacking funds. When they donate a tree to someone, they thank them for participating in the campaign.

This Alexandria neighborhood campaign represents one model for how to organize a local tree drive. Other neighborhoods have come up with their own plans. Neighborhoods across Northern Virginia are starting to think about how they can participate in the five year Plant NOVA Trees campaign. Some may want to emulate the professional installation approach. Others might prefer to plant smaller specimens, which are less expensive (sometimes even free) and require less watering, though they need careful protection from lawn mowers and deer and will need some simple pruning to direct their growth after a couple years.

The first step will be for residents to take the initiative to create a project for their own neighborhood. It helps to plan well in advance of a spring or fall planting, because it may take time to source the trees as well as to create enthusiasm in the community and work out a plan for watering and maintenance. Tips on how to organize can be found on the Plant NOVA Trees website. Plant NOVA Trees is the collective effort of thousands of individuals across the region pitching in to get thousands of trees into the ground.

Arlington National Cemetery Treasures its Trees

Article by Plant NOVA Trees

Arlington National Cemetery is a place to honor, remember, and explore. The beauty of the grounds and the comfort of its visitors is enhanced by close to 10,000 trees, some dating back to before the Civil War. The diverse collection of this Certified Level III Arboretum include many species native to Northern Virginia including the state co-champion Pin Oak, near the Memorial Amphitheater. (A champion tree is the largest representative of its particular species within a geographic area.)

Arlington National Cemetery is dotted with native trees such as Redbuds with their lavender flowers in spring, Black Gum with its bright red fall foliage, and American Hollies that shelter the birds. Oaks are the most common species, which reflects their predominance in the Eastern forest.

Forester Greg Huse gives tours of the arboretum to visitors four times a year and points out the ecosystem services provided by mature trees. That Pin Oak, for example, not only supports the caterpillars that are the food for baby songbirds – a feature intrinsic to native plants but nearly absent in non-native ones – but also absorbs 1,400 pounds of atmospheric carbon and intercepts 23,000 gallons of storm water every year.

After President John F. Kennedy was assassinated in 1963, a landscape architect firm designed the Kennedy memorial site, home of the Eternal Flame. The designers worked around a 200 year-old Post Oak, 60 inches in diameter, which later became known as the Arlington Oak. In 2012, this massive tree was blown down by Hurricane Irene and could not be rescued. By good fortune, though, its acorns had been collected by American Forests as part of their historically significant trees project. Three of those saplings were donated back to Arlington Cemetery and planted in the same plaza, where they are now ten to twelve feet tall and thriving.

Trees are not the only native plants at the cemetery. Horticulturalist Kelly Wilson has been steadily adding a diversity of herbaceous and woody plants throughout the last decade, especially in the newer bio-retention areas (rain gardens). In these public areas, she designs with a small number of species to keep a neat-and-clean look, while in a staff parking area, she allows for more exuberance. Favorite natives utilized are the purple-flowering Ironweed which attracts many pollinators. Monarch caterpillars have taken advantage of the Butterflyweed. River Birch with its beautiful peeling bark does very well in rain gardens.

The 639 acres of Arlington National Cemetery, which is the resting place for 400,000 American servicemembers and family, are cared for by five permanent staff members who supervise the work of 90-100 contractors. The trees that grace this National Treasure are an essential feature, just as they are in any neighborhood where residents value the beauty and services they provide.

To learn what you can do to plant and protect trees on your own property, visit www.plantnovatrees.org. Many of the trees will still have their fall colors in November when Arlington National Cemetery hosts the Centennial Commemoration of the Tomb of the Unknown Soldier. On November 9-10, a flower ceremony takes place where the American public will be able to place a flower at the Tomb of the Unknown Soldier. On November 11, an Armed Forces full honors procession takes place as it did a hundred years ago on November 11, 1921. Find out more about the Tomb of the Unknown Soldier Centennial Commemoration at www.arlingtoncemetery.mil.
