Many Miles, Many Years, Many Potential Impacts: The Mountain Valley Pipeline

By Emelia Delaporte and Sean Weinstock

After a decade filled with controversy the 303-mile-long Mountain Valley Pipeline became operational on June 13, 2024. Crossing several Appalachian counties, the pipeline has been a flashpoint for environmentalists concerned with the impact of expanding fossil fuel use on global warming, local industry and residents anxious to secure a reliable low cost energy source. This News Feed NRV mini-documentary provides an overview of the pipeline and presents both environmental and natural gas industry perspectives.

Virginia Tech professor discusses carbon project

Carbon dioxide emissions are a leading cause of global warming. Most solutions focus on reducing the use of fossil fuels. Dr. Ryan Pollyea, an associate professor in the Department of Geosciences, is pioneering research for a potential solution called carbon sequestration. This process captures carbon dioxide at the source and puts it underground.

Stomp on sight: the scourge of the lanternfly

As the New River and Roanoke Valleys embrace fall, an increasingly common pest  is laying the groundwork for its next generation. 

Why it matters: The spotted lanternfly, an invasive species, poses threats to agriculture, trade and native species. It is also a nuisance to property owners.

  • According to Virginia Tech’s Insect Identification Lab, by September lanternflies are in their adult stage and are beginning to lay egg masses. The eggs will overwinter and hatch in the late spring. 
  • They feed on grapevines and cause declines in the health, yield and sugar content of grapes intended for usage in the wine industry. They can also cause harm to stone fruit, hops and more.

The big picture: The existence of the spotted lanternfly (Lycorma delicatula) in the United States is thought to have originated from trade coming out of northern China.

  • It was first detected in the United States in eastern Pennsylvania in 2014. The first record of the species in Virginia was in Winchester in 2018.
  • Egg masses travel on pallets, ornamental rocks and shipping containers if preventative measures are not taken.
  • According to the Animal and Plant Health Inspection Service (APHIS), there are at least 17 states with recorded infestations.
  • Spotted lanternflies are well adapted to handling cold climates in this part of the United States, where there is only one generation a year, and could thrive in warmer ones similar to South Asia, where there are multiple generations in a year.

Zoom in: Spotted lanternflies are becoming established in Roanoke and Radford. Reasonably, this means there is potential for greater expansion within the New River Valley and Roanoke Valley.

  • “Radford is infested with spotted lanternfly. It’s on the edge of campus that faces towards the railroad tracks. We get reports from Fairlawn,” said Eric Day, manager of the Insect Identification Lab. “The other infestation area in Montgomery County is Ironto at that truck stop, there’s a population there as well too.”
  • One was even recently found on Virginia Tech’s campus following a tailgate. 

Zoom Out: Spotted lanternflies are adaptable and could be coming to your yard next.

  • They are effective at traveling on human transports. On their own, they may move three to five miles.
  • The preferred food source of the spotted lanternfly is tree of heaven, which is another common invasive species hailing from China. Increased presence of this tree means increased habitability of a location for the spotted lanternfly.
  • Spotted lanternfly droppings, referred to as honeydew, cause a sooty mold on other trees including maples. These droppings attract yellow jackets and other biting or stinging insects.
  • 12 counties and 10 cities in Virginia, mostly in the Shenandoah Valley and in Northern Virginia, are currently under quarantine regarding spotted lanternfly. Businesses in the area must obtain a permit from the Virginia Department of Agriculture and Consumer Services and undergo inspection for all regulated articles. 
  • “It’s that sort of unfortunate stage where they are moving into the established pest stage. It was new and we [were] looking for new reports and everything – that’s what took up a lot of time, getting the word out,” Day said. “And now, I hate to say it, it’s here.”

What we’re watching: New reports of spotted lanternflies are coming in frequently. Expansion has the potential to occur rapidly. 

  • While the most effective way to keep lanternflies away from home is to be cautious with purchases, there are also insecticides that consumers can choose to use.

If you find a spotted lanternfly in an area where an invasion has not already been identified, please be sure to report it to your local Virginia Cooperative Extension office.

Pawpaw season in the New River Valley

By Emelia Delaporte

As the first crisp notes of autumn begin to cut through the air, somewhere nearby North America’s largest native fruit falls quietly to the ground. Bewilderingly tropical and often overlooked, the pawpaw is in season and here to stay.

Pawpaws in the New River Valley – they ripen in early September. For a few weeks, they hold a cultural spotlight in the area. With festivals, tasting events and foraging available, this is possibly the best time of year to learn about this unique fruit – and why it is not commercially available. 

Despite their lack of year-round availability, and their lack of availability in stores in general, the pawpaw has a loyal following as an edible native. People want it in their hands, in their kitchens and in their yards. Passionate growers like Jesse Kelly are working to make that possible. 

“Just in Virginia, the extremes of flavor…. [It’s] often described from banana to mango to cardamom, almost,” said Kelly, executive director of the nonprofit Nursery Natives. “Or a caramel-type flavoring.”

While there is not an abundance of pawpaw-related recipes, due to their lack of longevity, fans find them great to eat as they are or find new ways to use them. Common recipes include pawpaw bread, pawpaw ice cream, pawpaw salsa and more. 

Ava Pope, a landowner in Giles County, sources her pawpaws from two trees that her partner planted around 25 years ago. Purchasing saplings has the potential to be wildly successful. With six or seven years of patience, a healthy tree can produce hundreds of fruit with each harvest.

“Trees that produce, we have two,” Pope said. “Between those two trees, we’ve gotten anywhere between 100 and 200 pounds per season.”

Her average pawpaw weighs about a third of a pound, and her biggest one weighs three quarters of a pound. Her two producing trees are six to eight inches in diameter at breast height and around fifteen feet tall.

Pope also has pawpaw trees on her property that were not human-planted. She is not sure whether these other trees were completely wild or whether they sprouted from seeds dispersed from her planted trees. 

Either way, typically these other trees do not produce. This could be for a variety of reasons; for starters, they receive less light than the two fruiting trees, which were carefully positioned. These other trees are smaller, potentially from being of a more wild stock, or also due to lack of sunlight, or both. 

Additionally, they might be clones of each other, which would limit fertilization necessary to produce fruit. Wild pawpaws sprout most often from suckers instead of seeds. Suckers are sprouts from the roots of an existing tree, resulting in a genetic clone of the original tree. To that end, pawpaws in the wild often exist in colonies, or clonal stands. For those stands to bear fruit, pollen must come from pawpaws outside of the colony. 

The two fruiting trees are enough for Pope, though. For her and her eight year old son, Onyx, their fruiting trees are fun to eat fresh, to give away to loved ones and to sell to festivals, farms and more.

“Before we realized that lots of people liked them, they would just rot in the backyard. I think it was five or six years ago I realized, oh, maybe we should do something with these,” Pope said.

Growing your own pawpaws is not always easy, but it does not need to be complicated. John Peterson, an advanced lab specialist at Virginia Tech, grows saplings at his farm.

“I have had really good luck planting larger pawpaws. If they’re three feet high, containerized – almost guaranteed success,” Peterson said. “ Eight inch high, bare root? Almost guaranteed they’ll die. All my successful pawpaws were tall when I planted them.”  

If starting from seed, prospective growers will need to wait a while. Pawpaws need a cold, moist stratification period to complete their embryo dormancy period. Putting fresh seeds in damp paper towels in the fridge through the winter will mimic them spending the winter in the ground. Once the stratification period is over, the seeds will be better able to sprout. 

Pawpaws do best in a rich, moist soil. According to Peterson, much of their range is underlaid by limestone. This indicates also that they do better with a less acidic – or, sweet – soil. Trees like sugar maple, bitternut hickory and American basswood are possible associates. 

They have an expansive range – most of the eastern United States, the southern United States and the midwest have pawpaw species native to them. They even grow north into Canada. Asimina triloba, the common pawpaw, is the local species to the New River Valley and has the greatest range of the multiple species in the Asimina genus. 

So far, Peterson says, the range is not contracting or expanding with climate change. However, the tree seems to be proliferating within its pre-existing range. Human development practices like clear-cutting are creating much more space where sunlight reaches the ground, and that is what pawpaw loves most. 

This increasing availability of the fruit itself does not mean that shoppers will see pawpaws on grocery store shelves any time soon. 

“In order to make [pawpaws] a marketable product, we have to figure out how to store them and ship them… once you’ve picked them, the fruits are only good for like, two days,” Peterson said. “They really fall apart fast, they bruise easily – they are, I think, a terrible marketable product.”

For the coming month, though, they will be marketed at festivals. The two festivals being advertised in the New River Valley are the 2024 Paw Paw Festival in Pearisburg on Sept. 28 and 29 and the New River PawPaw Fest in Radford on Oct. 5. 

Hopefully someday, growers and scientists will figure out how to make the fruits last longer. Until then, the most reliable way to get pawpaws will be to know where to forage, to go to festivals or to grow them in your own backyard.
