By the Numbers: 110,701

In a watershed whose population has expanded by more than eight million people in the last 50 years, protecting land while allowing urban and suburban growth can pose a challenge. But one piece of Maryland’s land protection puzzle has proven successful in protecting forests and, according to some, could provide guidance to other regions interested in keeping trees on land that is threatened by residential development. 

The Maryland Forest Conservation Act fosters forest retention and replanting during development. It has had a significant and positive effect on Maryland’s forest cover.

The Maryland Forest Conservation Act was passed under Governor William Donald Schaefer in late 1991 and implemented at the local level by county and municipal governments in 1993. It was designed to reduce forest loss following development and is the only statewide forest conservation regulation in the nation to focus on forest retention and replanting during the construction permitting process.

The Act affects those who propose land use changes on properties of one acre and greater in size and that require a subdivision approval, grading permit or sediment control permit: for example, a homeowner who wants to add a new residence to his property or a developer who wants to build a subdivision. These landowners must work with a licensed forester, licensed landscape architect or other qualified professional to submit their plans to protect trees during construction and to mitigate construction by retaining a portion of existing forest cover or by planting new trees.

By its nature as a required rather than optional regulation, the Act affects and engages a wide swath of landowners in planting trees and protecting land. “We’re more restrictive here [in Maryland than in other states] on what happens [to land] during development. There are a lot of environmental laws at the local level and at the state level that you need in order to get your building permits. Other states aren’t that way,” said Marian Honeczy, Urban & Community Forestry Programs Manager with the Maryland Forest Service.

Some landowners have argued against planting new trees when their proposed developments don’t involve removing them. But as Honeczy explains, the Act was meant to engage everyone in the work of environmental conservation. “Governor Schaefer felt that everyone should bear the burden of protecting the Bay, since we’re all sharing the benefits. It didn’t matter if you had a forested site or a farm field [slated for development]. Everyone had to comply with the law.”

That said, not everyone bears the same burden. Different zoning categories have different afforestation and reforestation thresholds and different forest retention amounts. In other words, those developing a farm field may have to plant fewer trees than those developing a woodlot. “But you’re still planting trees,” Honeczy said.

Healthy forests protect clean air and water and provide food and habitat to wildlife.

Healthy forests are critical to a healthy Chesapeake Bay: they protect clean air and water and provide food and habitat to wildlife. (For this reason, the Chesapeake Bay Program has committed to expanding urban tree canopy by 2,400 acres by 2025.) And for Honeczy, the Forest Conservation Act has “more than accomplished” its intended goal of conserving forests in the face of development. Indeed, research suggests the regulation has had a significant and positive effect on Maryland’s forest cover, and the numbers seem to agree: In the first 20 years of the Forest Conservation Act, 110,701 acres of forest land were put under protection from development. That area is two and a half times bigger than Washington, D.C.!

The Act does face challenges—in the form of finite land and finite funding—but it was “never intended to be the sole answer for all of our forest cover and urban tree issues,” Honeczy said. Just as protecting forests was not intended to be a burden on the shoulders of one landowner, it was also not intended to be a burden on the shoulders of one law, one program or one state agency.

Whether it is through the Woodland Incentive Program—which provides cost-share assistance for tree planting and timber stand improvement on forests between five and 1,000 acres in size—the Lawn to Woodland program—which fully funds the conversion of one- to four-acre lawns to forests—or the Marylanders Plant Trees program—which provides coupons to homeowners who want to purchase trees to plant—the Maryland Forest Service and their partners across the state will continue to connect anyone who wants to plant a tree with people and programs that will help them do so.

“Trees do so much in a cheap, efficient way to protect the Bay,” Honeczy said. “And every person can plant a tree on their property.”

Websites aim to promote planting, protection of trees in Bay region

Charlie Conklin, President of Gunpowder Valley Conservancy, cuts a protective tube from a tree planted along Dulaney Branch in Baltimore County, Md., on April 21, 2016. The trees are part of a 75-acre riparian forest buffer project planted in Baltimore County between 2005 and 2007.

Two new websites will help those working to plant and protect trees throughout the Chesapeake Bay watershed. The Chesapeake Riparian Forest Buffer Network and Chesapeake Tree Canopy Network—both launched through partnerships between the Chesapeake Bay Program’s Forestry Workgroup, the Alliance for the Chesapeake Bay and the U.S. Department of Agriculture Forest Service—were created to help communities meet their forest buffer and tree canopy goals.

Chesapeake Riparian Forest Buffer Network

In recent years, the rate of streamside forest buffer plantings has been declining. But forest buffers are considered one of the most cost-effective practices for reducing pollution because of their ability to efficiently trap and filter pollutants carried by runoff. The Chesapeake Riparian Forest Buffer Network website was developed as a resource for those who are working to increase the amount of riparian forest buffers in the Chesapeake region.

The website’s features include:

  • An interactive map showing the progress of counties across the watershed in enrolling landowners in forest buffer programs,
  • Information on the importance of forest buffers and tips on how to successfully plant and maintain buffers,
  • Success stories illustrating the multitude of benefits buffers can provide, from water quality to economic benefits, and
  • Resources on funding opportunities and outreach strategies.

Chesapeake Tree Canopy Network

Trees in urban and suburban communities provide an array of benefits: cleaning the air, reducing polluted runoff, providing shade and enhancing quality of life. The Chesapeake Bay region is home to a hard-working network of champions for community trees, and the Chesapeake Tree Canopy Network was created to help them on their way toward reaching their tree canopy goals.

The website’s features include:

  • Community Spotlight stories to connect, support and showcase the existing network of tree canopy champions,
  • An interactive map showing the results of local tree canopy assessments, community tree canopy goals and points of contact,
  • Information on the importance of urban and suburban trees and how to assess, expand and maintain community tree canopy, and
  • Resources on funding opportunities and outreach strategies.

As part of the Chesapeake Bay Watershed Agreement, Chesapeake Bay Program partners committed to meeting goals for both riparian forest buffers and tree canopy. The riparian forest buffer goal is to restore 900 miles per year of streamside forest buffers, as well as conserve existing buffers, until at least 70 percent of the areas along streams throughout the watershed are forested. The tree canopy goal is to expand urban tree canopy—the layer of trees covering the ground when viewed from above—by 2,400 acres by 2025, providing air quality, water quality and habitat benefits throughout the watershed. The websites were created to support the achievement of these goals.

Discovering the hidden world of forest fungi

A walk through the 500-plus acres of woods at the Ned Smith Center for Nature & Art in late October shows the diversity of a forest ecosystem. Fungi spotted include a coral-pink merulius (top left), a blue cheese polypore (second row, second from left), and witches’ butter (third row, third from left).

About thirty minutes north of Harrisburg, Pennsylvania, the Ned Smith Center for Nature & Art sits on over 500 acres of protected forest land with the Wiconisco Creek, a tributary to the Susquehanna River, running through it. The Center offers a variety of educational programs about nature, art and conservation. But on this crisp day in October, I was meeting up with Jerry Hassinger, a volunteer at the center and a noted mushroom hunter, to see what kinds of wood-eating fungi we could find.

Often overlooked, wood-eating fungi are a key component of what keeps a forest ecosystem healthy and functioning properly. Forest land acts like a sponge, absorbing air pollution, trapping polluted runoff before it reaches waterways and stabilizing the soil while providing a habitat for a diverse group of critters. Keeping forests healthy leads to clean waterways, which in turn helps protect and restore the Chesapeake Bay.

Jerry Hassinger tries to identify a fungus on the trunk of a tree at the Ned Smith Center for Nature & Art near Millersburg, Pennsylvania, on October 28. Hassinger is retired from the Pennsylvania Game Commission and a regular volunteer at the Center.

Hassinger is a regular volunteer at the Center and has written, photographed and spoken about the importance and beauty of fungi for most of his life. His passion for fungi and background in environmental science was immediately apparent upon my arrival, when he handed me a folder containing a piece of photo paper with beautiful images of fungi we were likely to see on our hunt that day. Each photo was neatly numbered and labeled with the common name and the page number where I could look it up in his edition of the National Audubon Field Guide. Hassinger, formerly with the Pennsylvania Game Commission, humbly considers himself a “fungi enthusiast”—not an expert.

The rest of our mushroom hunting party consisted of Beth Sanders, Director of Education for the Center, and Santino Lauricella, Environmental Educator for the Center. We set off at an appropriately slow clip, looking for what I assumed would be small, ground-dwelling fungi. Hassinger said he uses looking for fungi as an excuse to hike slowly along trails, “I just crossed the eighty year mark, so I don’t walk fast.” He did, however, scramble up a few slopes and down into the creek bed with more agility than I did.

Forest at the Center shows off fall colors on October 28. Once a tree dies, wood-eating fungi recycle the fallen giants back into the forest floor.

Jerry Hassinger points out the characteristics of a wood-eating fungus called false turkey tail at the Center.

In the few miles we covered, we saw more shapes, textures and sizes of fungi than I ever expected would exist. I learned about white cheese fungus, so-named because it looks like the wet crumbles of goat cheese; ceramic parchment, which covers entire fallen trunks in small, light brown segments resembling tiles; and pear-shaped puffballs that expelled a dusty brown cloud when squeezed. We also saw false turkey tails, deadly galorina, bearded tooth and hen of the woods.

A forest ecosystem is constantly regenerating, and wood-eating fungi play a major role in recycling fallen trees. They digest the dead wood and release nutrients from the bark back into the soil, supporting new growth and reducing fuel available for forest fires.

“Beth!” Hassinger shouted across a clearing as he tromped through the leaves off trail to point out our next mushroom find. “This next one is going to blow your mind.”

Wiconisco Creek runs through the Center and empties into the Susquehanna River in Millersburg, Pennsylvania.

From a distance, I could make out an off-white mass that protruded from the bottom of a tree about a few hundred yards from the trail. Hassinger bounded over to it, obviously excited to show us this particular specimen that was about the size of a kid’s basketball. Long, white, hair-like structures covered the rounded form to make it look more like a mythical woodland creature than a mushroom.

Hassinger said it had survived for over a month already and that this fruiting body was just the visible part of what was probably a much larger web of mycelium. Mycelium is a network of millions of microscopic threads that attaches to roots and logs and grows through the soil, sometimes for miles. It forms mutually beneficial relationships: effectively expanding the reach of tree and plant root systems, protecting against some pathogens and providing minerals and water to the roots as it takes sugars produced during photosynthesis. Even more astounding is that mycelium acts as a kind of communication system for the forest. If a tree is attacked by insects, the mycelium will produce a chemical making it less desirable to eat. That chemical works its way through the network of roots and mycelium to other trees of the same species, prompting them to produce that same chemical and ward off the attack.

Walking through the forest with Hassinger, I gained a new insight on just how much is happening all at once, on so many different levels of the forest. You may be pleasantly surprised at what you find when you take the time to look closely.

Maple syrup may face not-so-sweet future in Bay region

Visitors gather for a demonstration during the 46th Annual Maple Syrup Festival at Cunningham Falls State Park in Thurmont, Md., on March 20, 2016. The region's maple syrup industry might suffer as climate change pushes the range of maple-beech-birch forests northward.

It’s a cold, overcast day in Mid-March, and dozens of onlookers are huddled around a wooden shelter, watching steam billow off the top of a cast-iron pot. The gathering is part of the 46th Annual Maple Syrup Festival, held at Maryland’s Cunningham Falls State Park, and a curious audience is listening to Maryland Park Ranger Jeremiah Corbin describe how the sweet sap produced by sugar maple trees is boiled into pure maple syrup.

Each year, volunteers and attendees at the festival celebrate all things maple syrup. Visitors can partake in a pancake breakfast, sample maple candies and creams, and watch a demonstration of the syrup-making process, from techniques used hundreds of years ago to current tree-tapping technologies.


Maryland Park Ranger Jeremiah Corbin describes the modern method of using plastic tubing to collect maple sap. "We focus on quality, not quantity," said Corbin, noting that Maryland’s maple syrup output ranks 13th in the country.

When it comes to maple syrup production, Maryland isn’t first on the list—in fact, the state ranks near the bottom of U.S. syrup production (Vermont, of course, is number one). Of the Chesapeake Bay watershed’s six states, New York ranks highest, accounting for more than 15 percent of U.S. production. Pennsylvania typically accounts for around five percent, while Maryland, Virginia and West Virginia may produce a few thousand gallons of maple syrup a year. But much of the region falls along the southern edge of maple syrup production, meaning these may be some of the first areas to experience how a changing climate affects this cultural and economic tradition.

Late-winter temperatures—warm, sunny days followed by cool nights—are crucial to start the flow of the sugar maple’s watery, slightly-sweet sap. But temperatures across the globe have been steadily rising, with 2015 the warmest year on record, and these warmer temperatures could affect the habitat and health of trees like the sugar maple.


Maryland-made maple syrup is offered at the Annual Maple Syrup Festival.

As temperatures warm, certain areas may no longer be suitable habitat for tree species that are common today, including the sugar maple. The Maryland Climate Action Plan suggests maple-beech-birch forests are likely to fade northward and be replaced by species currently found south of the state. Even low-range predictions from the U.S. Forest Service’s Climate Change Atlas suggest suitable habitat for sugar maples will retreat to the northern reaches of the watershed over the next 100 years.

According to scientists with the Acer Climate and Socio-Ecological Research Network, or ACERnet, the potential effects of climate change on maple syrup production could include not only the amount of trees available to tap, but also the health of those trees, the tapping season and the quality of sap. If suitable sugar maple habitat shifts northward, climate-stressed trees left in the area may become more susceptible to threats like pests and disease. And although syrup producers have already seen tapping seasons starting earlier and becoming more unpredictable, more research is needed on whether climate change will affect the sweetness of the sap.


Wooden and metal stiles, or spouts, show how maple sugaring technology has changed since Native Americans first used cutting methods to collect maple sap.

Still, there’s no need to bid farewell to locally-made syrup just yet. By adapting to a changing tapping season, producers in northern states may be able to continue collecting sap. And advanced technologies like vacuum tubing systems may help those in southern ranges continue production, at least for a little while. Either way, the maple syrup festivals of the next century may look quite different from the ones we’re used to today.

A bonsai endures, even after an atomic blast

At the U.S. National Arboretum in Washington, D.C., a diminutive Japanese white pine tree rests unassumingly on an outdoor table, its vibrant green leaves belying its age. The 390-year-old tree, first cultivated in 1625, was a mere 320 years old when it survived the atomic blast that destroyed Hiroshima, Japan, during World War II. And the tree is gaining renown this week as it is honored to commemorate the 70th anniversary of the bombing. As part of the permanent collection at the arboretum’s National Bonsai and Penjing Museum, it helps form a tiny flourishing forest.

The museum’s three pavilions, housing about 150 plants, are part of the 446 acres of lush fields, forests and gardens making up the arboretum. Home to one of the largest bonsai and penjing collections in North America, the museum was established in 1976, while the arboretum dates to 1927.

The arboretum’s research program in ornamental horticulture and plant exhibits draw more than 500,000 visitors each year, allowing the staff to showcase a repertoire of educational programs, workshops and demonstrations about horticulture, agriculture and forestry.

A 390-year-old bonsai that survived the atomic bomb blast over Hiroshima during World War II resides at the National Arboretum's National Bonsai and Penjing Museum in Washington, D.C., on July 22. The tiny Japanese white pine was first cultivated in 1625 and donated by bonsai master Masada Yamaki for America's 1976 bicentennial.

Froning, a trident maple gifted by Keizo Obuchi and cultivated since 1919, a musk maple gifted by William and Joan Clark and a trident maple gifted by Froning reside at the museum.

The National Bonsai and Penjing Museum got its start when Japanese bonsai enthusiasts in the Nippon Bonsai Association donated 53 bonsai and 6 viewing stones to the people of the United States for the country’s bicentennial.

Some of the museum’s trees have been cultivated for hundreds of years.

Restoration Spotlight: Fostering environmental stewardship through forest restoration

Forests are critical to the health of the Chesapeake Bay—they protect clean water and air, provide habitat to wildlife and support the region’s economy. However, since European settlement of the region in the 17th century, deforestation has taken a toll on the once thriving forests of the mid-Atlantic region. Human influences such as development and parcelization have reduced forest acreage from 95 to about 45 percent of historic coverage.

Deforestation in the Bay region may seem a problem that is too complex to tackle, but one man, dubbed the modern-day Johnny Appleseed, is proof that a little curiosity, passion and hard work can have profound effects on the environment. John Smucker, a Technology Education teacher at Northwest Middle School in Taneytown, Maryland, has become a catalyst for reforestation efforts, melding his engineering experience with restoration initiatives.

Smucker recalls the moment 10 years ago that sparked his interest in forest restoration. “It all started behind my house with a reforestation effort, but all of the trees that were planted slowly died. I didn’t like that so I did a lot of research to help [the trees] out and fell in love with the process, which led me to start dropping acorns into empty tree shelters,” said Smucker.

The moment created a ripple effect that resulted in Smucker spearheading forest restoration by organizing volunteer plantings and entering into a partnership with Mount Saint Mary’s University and the Francis Scott Key Center. Both locations provide space for Smucker to grow the thousands of trees he uses for plantings. 

Smucker spends about 700 hours every year in all aspects of creating riparian buffers, like meeting with landowners, auguring the holes, organizing the volunteers and also conducting the most critical part of the process Smucker says, maintenance. Plantings are held on Saturdays during April, May and October – the most opportune months for tree survivability and comfortable outdoor temperatures for volunteers to work.

When choosing planting locations, Smucker explains, “Being a grower really is a game changer for me, because I can fully understand what the trees need to survive.” Once a site is selected, he samples the soil, observes what plant species are in the area, spends time in his greenhouses flagging all of the appropriate trees for the site and rallies his volunteer base around the planting.

When it comes to tree plantings, the name of the game is fun and education. Many of his volunteers are young people who are in a mindset to learn. Each planting is preceded with an ecology lesson highlighting the importance of riparian zones, stream shading and nutrient removal. “As a middle school teacher it is important to organize the event so it’s fun and rewarding, because if they get frustrated, they will associate that frustration with tree planting. If they associate it with fun, then the environmental stewardship will perpetuate a lot better. If it’s organized right and goes smoothly then it’s a feel-good thing, just like in the classroom,“ Smucker explained.

Smucker encourages his students to work out solutions to engineering problems with the tree plantings and challenges them to think up innovative ways to overcome obstacles. “Tree planting and technology education are really the same thing. It’s problem solving and the engineering design process. What is the problem? What is the solution? Evaluate and modify,” said Smucker.

Over the years, Smucker’s volunteer base and partner organizations have expanded to the point where he has been able to launch an organization of his own, Stream Link Education, a nonprofit that organizes and leads tree plantings with local community members, organizations and businesses. “The coolest thing I think we do is Natives for Nonprofits. We grow trees for giveaways to other organizations, which is great because budgets are really tight and donations are hugely welcome. It also helps establish partnerships, not because I want something in return but because it’s neat to make connections,” said Smucker.

Smucker aims to perpetuate choices and actions by providing people with hands on educational experiences. “If you’re excited about something and value it, then demonstrate the value, they [the volunteers] will see it. The excitement can be catching,” he said. He continued to explain that in addition to educating others and improving the environment, his enthusiasm for restoration remains strong because he is still able to grow as well, “I’m going to turn 50 in January and I’m thinking, ‘if I do this right, I’ve got my 50’s and 60’s and if I can stay healthy, I can do this for a long time.’ And that’s great. There is always something to learn.”

Forests clean our air, save our lives

The nation’s forests save more than 850 lives each year, according to a new report from the U.S. Forest Service.

In a study that will be published in the October issue of Environmental Pollution, scientists with the U.S. Forest Service have determined the magnitude and economic value of the effects trees have on air quality and human health. While we have long known that trees remove pollutants from the air, this study shows that in 2010, trees in the conterminous United States removed 17.4 million tons of pollution, with a human health value of $6.8 billion.

In addition to saving more than 850 lives, these trees reduced more than 670,000 incidences of acute respiratory symptoms and 430,000 incidences of asthma exacerbation. Trees also saved 200,000 lost days of school.

A forest’s pollution removal rates can be affected by pollution concentrations, tree cover, weather conditions, length of growing season and other environmental stressors. In general, scientists found that while trees’ pollution removal was greater in rural areas, the economic value of this pollution removal was greater in urban areas. In other words, because of their proximity to people, trees in urban areas have a greater impact on human health.

“More than 80 percent of Americans live in urban areas containing over 100 million acres of trees and forests,” said Michael T. Rains, director of the Forest Service’s Northern Research Station in a media release. “This research clearly illustrates that America’s urban forests are critical capital investments [that are] helping produce clean air and water [and] reduce energy costs and making cities more livable. Simply put, our urban forests improve people’s lives.”

The Chesapeake Bay Program has set a goal to expand urban tree canopy by 2,400 acres by 2025. Indeed, trees can improve air quality, water quality and habitat in ways not discussed in this study. Trees near buildings, for instance, lower energy use. Trees along rivers and streams reduce the amount of nutrients entering local waterways. And trees provide food, shelter, nesting sites and safe migration paths for critters in the water and on land.

“Urban tree planting is part of the Watershed Improvement Plan for six Bay jurisdictions,” said U.S. Forest Service Chesapeake Liaison Sally Claggett. “To reach water quality goals, these jurisdictions are targeting nearly 20,000 acres of new tree canopy by 2025—so the goal of 2,400 acres may be reached early. Partners are planning an Urban Forestry Summit in fall 2014 to help make that happen.”

Photo Essay: Walking the woods of the Chesapeake Bay watershed

For close to 50 years, Nick Carter has owned 33 acres on Maryland’s Eastern Shore. Aside from a houses, a few sheds and a trail or two, much of this land has returned to its natural state: former farm fields have become bogs, wetlands and forests, pushed along by natural growth and Carter’s deep-seated desire to create healthy habitat and clean water.

Carter’s property runs next to the Choptank River, which flows into the Chesapeake Bay. Close to one-third of the Choptank watershed is forested, covered with the tree-and-shrub-filled habitat considered the most beneficial land use for the Bay. Forests absorb airborne pollutants, keep nutrients and sediment from entering our rivers and streams, and provide food, shelter and safe migration paths for wildlife. It is for these reasons that Carter has allowed forests to dominate his land.

“I’d like to see this little bit of property go back to old growth,” Carter said, referring to a type of forest that has evaded unnatural changes for a century or two. Carter and his wife purchased their property when he finished graduate school in 1966. For 35 years, Carter worked as a fish biologist with the Maryland Department of Natural Resources (DNR). Now, he offers informal tours to naturalists, native plant societies and school groups, carrying along a walking stick that effectively points out the things visitors might not notice.

Take the plants, for example. There are 250 species on Carter’s property, and in one two-hour walk it seems he can point out most of them. There are spring ephemera like jack-in-the-pulpit and pink lady’s slipper, the latter of which has a relationship with underground fungi that make them almost impossible to transplant. There are cinnamon ferns and sphagnum moss in a bog that Carter is particularly proud of because he created it with the simple act of laying down a few logs to form a makeshift dam. And there are the pine and oak trees that dominate the upland woods, including the willow oak whose acorns are so small that blue jays can pick them up and carry them in their beaks.

Then there are the reptiles and amphibians. Carter has counted 30 species of these, from the tree and wood frogs that favor damp habitat to the broad-headed skink and Eastern fence lizard that like forests with abundant leaf litter. Leaves that litter the ground conserve water, recycle nutrients and offer shelter to small critters. Its presence on Carter’s land can be felt as soon as you step from the hard pavement of Draper’s Mill Road to the soft, spongy forest floor.

Carter’s woods are home to charismatic fauna, too, including 30 species of mammals and 85 species of birds. Because so much of the property is forested, it serves as suitable habitat for “forest interior dwelling” birds, or those birds that need the moderate temperatures and light levels found deep within the woods. Carter has spotted pine warblers, prothonotary warblers and ovenbirds, but on our walk we spotted a bird that was much bigger and a little less particular about its habitat: a female wild turkey on her nest in a grove of skunk cabbage.

These critters flourish here because Carter has done so little to disrupt the natural processes of the world around him, aside from building the dam that led to the bog and managing some invasive species. While Maryland’s white-tailed deer often chew up low-growing plants, changing the structure of area forests, Carter’s dogs have warded them off with their loud howls. And when invasive plants like autumn olive, oriental bittersweet, English ivy and bush honeysuckle start to grow, Carter steps in to exert control. “Some I spray, some I cut, some I pull,” he said.

The changes that have taken place on Carter’s land present a classic case of succession: disturbed ground is replaced by shrubs, shrubs are replaced by pines and pines are replaced by hardwoods. In other words, this land works “the way it ought to work,” Carter said. And it reminds us of the habitats the Maintain Healthy Watersheds Goal Implementation Team is working to preserve in order to demonstrate the challenge of protecting streams.

Carter’s work to bring people onto his property could help further this goal, as he shares knowledge that can inform and inspire his visitors. “Here’s a little piece of land on which I can make all the rules,” Carter said. “Here, I can make this land good for the Bay and its rivers. And I can show people what’s good for the Bay and its rivers.”

New strategy to guide forest restoration across watershed

Clean air, clean water and healthy communities: the benefits of forests are vast. But as populations rise and development pressure expands, forests across the Chesapeake Bay watershed are fragmented and cut down.

In an effort to slow the loss of Chesapeake forests, the U.S. Forest Service has released a restoration strategy that outlines how officials and individuals alike can improve the environment and their communities by planting and caring for native trees.

According to the strategy, which has been endorsed by each of the watershed's seven State Foresters, expanding forest cover is critical to improving our air and water, restoring wildlife habitat, sequestering carbon and curbing home energy use.

To ensure we get the most “bang” for our tree-planting buck, the strategy targets restoration efforts toward those places in which forests would provide the greatest benefits, from wildlife corridors along streams and rivers to towns, cities and farms.

Trees along the edges of streams and rivers—called a riparian forest buffer—can keep nutrients and sediment out of our waters and nurture critters with vital habitat and food to eat. Trees in towns and cities—called an urban tree canopy—can clean and cool the air, protect drinking water and boost property values, improving the well-being of an entire neighborhood at a low cost. And trees on farms—in the form of wind breaks, forest buffers or large stands of trees—can protect crops, livestock and local wildlife while providing a farmer with a new form of sustainable income.

Other areas targeted for forest restoration include abandoned mine lands in headwater states and contaminated sites where certain tree species could remove toxic metals from the soil.

Maryland homeowners plant big trees for big Chesapeake Bay benefits

Sometimes, even a single tree can make a difference. And it helps when that tree is a big one. 

For six seasons, Baltimore County has held a Big Trees sale in an effort to put big, native trees in Maryland backyards. Since its inception in 2009, the program has sold more than 750 trees to Maryland residents, augmenting the state’s existing forests and moving Baltimore County closer to its pollution reduction goals.

Big trees are integral to the health of the Chesapeake Bay. Forests clean polluted air and water and offer food, shelter and rest stops to a range of wildlife.

But big trees can be hard to find. To provide homeowners with the native trees that have high habitat value and the heft that is needed to trap polluted runoff, species like pin oak, sugar maple and pitch pine are grown in a Middle River, Md., reforestation nursery. The one-acre nursery, managed by Baltimore County’s Department of Environmental Protection and Sustainability (EPS), began as a staging ground for large-scale plantings but soon expanded to meet a noticeable residential need.

“We used to give incentives to homeowners to buy large trees at retail nurseries,” said Katie Beechem, Environmental Projects Worker with the EPS Forest Sustainability Program. “But we found that homeowners were buying smaller species—flowering dogwood, crape myrtle—that didn’t achieve the same benefits…that large native trees like oaks and maples and river birch can provide. We were able to fill this big tree niche.”

Emails, signs and word-of-mouth spread news of the sale to homeowners. Some travel from the next town over, while others come from as far as Gettysburg, Pa., to walk among rows of seedlings in black plastic pots.

Staff like Jon-Michael Moore, who supervises the Baltimore County Community Reforestation Program, help residents choose a tree based on growth rate and root pattern, soil drainage and sunlight, and even “urban tolerance”—a tree’s resistance to air pollution, drought, heat, soil compaction and road salt.

One Maryland resident picked up 15 trees to line a fence and replace a few that had fallen. Another purchased two trees to soak up stormwater in his one-acre space. And another chose a chestnut oak simply because she had one when she was a kid.

Out of the 12 tree species that are up for sale, oaks remain the favorite.

Whether red, black, white or pin, oaks are often celebrated as the best big tree. Oaks thrive in a range of soils, drop acorns that feed squirrels, woodpeckers and raccoons and create a home for thousands of insects.

Discussing the oak, Moore mentions University of Delaware professor Doug Tallamy. The entomologist once wrote that a single oak tree can support more than 500 species of caterpillars, which will in turn feed countless insect-loving animals.

But can one big tree make a difference for the Bay? Moore nodded: “Every little bit helps.”

Watershed Wednesday: Restore Mass Ave (Washington, D.C.)

The above 1913 photograph depicts rows of American lindens planted along Washington D.C.’s Massachusetts Avenue, west of Dupont Circle. The “double rows” of trees were planted in the 1880s, but many disappeared as the street was developed, new embassies were built, and utility lines installed. As a street that has historically been an international relations hub (it is home to major embassies), the loss of trees along Massachusetts Avenue seemed to represent the worldwide preference of commercialism over nature.

Today, the climate has shifted, and politicians jump at the chance to get their photo taken in front of a newly planted tree; but long before the diplomats grabbed their shovels (and press staff), Deborah Shapley was walking up and down Massachusetts Avenue, knocking on her neighbors’ doors, and asking them how far their hoses could stretch to water parched trees in the sidewalk.

Washington’s D.C.'s Department of Transportation's Urban Forestry Administration has taken the important step of planting trees along streets throughout the city, but it did not have the resources to water them. For young trees, lack of water lowers their chances of survival in Washington’s hot summers. Instead of complaining, Deborah encouraged her neighbors to take on the responsibility of watering their nearest city sidewalk tree as if it were their own.

“I started Restore Mass.Ave to be a model of how to get local property owners excited about taking care of the city trees near them.”

But convincing property owners to take care of a tree that isn’t technically in their yard is not so easy.

“People tend not to care about the landscape that is more than a house or two away,” explains Deborah. “So the cry for them to take care of trees beyond a certain distance, that’s just not practical to them.”

But since Deborah began Restore Mass Ave in 2007, more and more residents and embassies along the street have come to understand that these trees are dually beautifying their community and helping to absorb stormwater runoff.

In addition to caring for the 100 sidewalk trees installed by the city, Restore Mass has worked with Casey Trees to plant 125 new trees since 2007. Most of the 225 total trees are large shade trees, which absorb stormwater and lessen pressure on the neighborhood's combined sewer system.

Like most of downtown Washington D.C., Massachusetts Avenue has a combined sewer system (css), which collects water from both stormwater runoff and household’s sanitary sewage. The CSS conveys this to treatment plants to be cleaned before it flows into the Chesapeake Bay.

But during heavy rain events, the combined sewer system often overflows; the stormwater and sanitary wastes flow directly into the Anacostia or Potomac River. This can cause an excess of bacteria and other pollutants in Washington D.C.’s tributaries, rivers and the Chesapeake Bay.

While it is always important to find ways to decrease the amount of stormwater runoff flowing into storm drains, it is particularly crucial in neighborhoods with combined sewer overflows (roughly one-third of the District of Columbia).

“The city is under requirements from the EPA to rebuild the underground tunnels and pipes” associated with the combined overflow system, explains Deborah. “They’re only able to do a certain amount per year of underground infrastructure. But large trees naturally conduct precipitation down into the soil and lowers the burden the underground pipes.”’

Stormwater will instead be absorbed by trees, and help to recharge the groundwater so more plants can grow.

“If you have a continuous line of shade trees alongside of a gutter, less water flows into that storm drain, and less water is barreling around in the tunnels of the combined stormwater system,” Deborah says.

While trees help to absorb stormwater during rain events, they do need to be watered when it is not raining. Droughts and heat waves make it difficult for young trees to survive on their own. Luckily, Restore Mass Ave’s volunteers, known as “Treekeepers,” make sure care is given to every sidewalk tree.

Since roughly one-third of Mass Ave properties are foreign-owned, the organization works with embassies to plant trees on their grounds.

While it was once typical for embassies’ groundskeepers to maintain flowers the colors of the nations’ flags, it is now popular for embassies to also maintain the surrounding trees. Governments relate the activity to their climate change agendas. Groundskeepers become, in effect, "Treekeepers."

“They have a sense of ownership that they didn’t have before,” says Deborah. “When you give people who care for plants the chance to grow nearby sidewalk trees, they are delighted.”

As Restore Mass Ave encourages private homeowners and embassy staffs to care for trees in public space, the sense of shared community and stewardship multiplies.

“As in many neighborhoods, we found that the embassies don’t often talk to each other, but when you point out the common trees, and you engage all the staff, it becomes their common garden,” explains Deborah.

While Restore Mass Ave may have found a way to create a sense of an international environmental stewardship, Deborah, founder and president of the all-volunteer organization, concedes that the nonprofit would like to expand its influence, but not its area.

“The idea is to not take over a bigger and bigger area, but to get other people to start their own groups, such as Restore Georgia Avenue or Restore Connecticut Avenue. Only as more people here understand the importance and fun of growing trees, will DC become the ‘City of Trees’ as it was known a century ago."
