Reclaiming Appalachia: A Push to Bring Back Native Forests to Coal Country

Previous efforts to restore former coal mine sites in Appalachia have left behind vast swaths of unproductive land. Now, a group of nonprofits and scientists are working to restore native trees to the region — even if it means starting the reclamation process from scratch.

Near the top of Cheat Mountain in West Virginia, bulldozer operator Bill Moore gazes down a steep slope littered with toppled conifers. Tangled roots and angled boulders protrude from the slate-colored soil, and the earth is crisscrossed with deep gouges.

“Anywhere else I’ve ever worked,” Moore says, “if I did what I did here, I’d be fired.”

Moore is working for Green Forests Work, a small nonprofit, as part of a project to rehabilitate a rare red spruce-dominant forest on 2,000 acres that were mined for coal in the 1970s and 1980s. The mine became part of the Monongahela National Forest in 1989 when the U.S. Forest Service purchased more than 40,000 contiguous acres known as the Mower Tract.

Moore and other bulldozer operators hired by the nonprofit first knock down non-native Norway spruce and undesirable red pine. Then they score the heavily compacted dirt with three-foot-long steel blades; openings formed by this “deep ripping” allow newly planted native saplings, shrubs, and flowering plants to take root and thrive. The downed trees are left in place to curb erosion, build soil, and provide brushy habitat for birds and mammals.    

“Ripping so deep might seem extreme, but it’s the only way to give these native trees a chance,” says Chris Barton, co-founder of Green Forests Work and a professor at the University of Kentucky who specializes in forest hydrology and watershed management. “What’s on top of this mine site isn’t soil. It’s the spoil created when rock was blown up to expose the coal seam, and it’s really compacted.”

Such aggressive bulldozing is part of a new and evolving approach to healing forests destroyed by decades of surface coal mining in Appalachia, from Alabama to Pennsylvania. These lands were supposed to have been reclaimed in recent decades under the 1977 federal Surface Mine Control and Reclamation Act. But scientists and conservationists say that many of those reclamation efforts were failed or half-hearted efforts that did little more than throw dirt, mining debris, grass, and non-native trees over scarred lands.

Now, Green Forests Work and other groups are attempting ecological do-overs with the aim of restoring native forests on large swaths of previously reclaimed public and private lands throughout Appalachia. The deep-ripping technique developed by Barton, with support from a team of other scientists, involves uprooting the non-native trees and grasses planted by coal companies and starting the entire land restoration process from scratch.

At 2,000 acres, Cheat Mountain is Green Forests Work’s largest undertaking since it began operating as a nonprofit in 2013. Barton has partnered with public and private funders to coordinate the planting of more than 2 million trees on 3,300-plus acres in Appalachia. Other former mining sites that it is tackling include a 130-acre plot within the Flight 93 National Memorial near Shanksville, Pa., the former mine site where one of the four hijacked planes crashed on Sept. 11, 2001; a 110-acre site near Fishtrap Lake in Pike County, Ky.; and a 86-acre area within the Egypt Valley Wildlife Area in eastern Ohio. These and other planned restoration sites are part of an estimated 1 million acres that the federal Office of Surface Mining Reclamation and Enforcement (OSMRE) has designated as legacy coal mine sites.

New Healthy Soil Guide Gives Cooks a Better Recipe for Climate Change

This restaurant duo wants to spread the gospel that healthy soil on farms and ranches can play a major role in slowing global warming.

Author: Diana Donlon | Published: December 5, 2017

December 5 marks the United Nations’ World Soil Day, which recognizes the crucial role soil plays in human health, food production, and climate change mitigation. To mark the occasion, Diana Donlon, director of the Center for Food Safety (CFS)’s Soil Solutions program, spoke with Anthony Myint and Karen Leibowitz, owners of The Perennial Restaurant in San Francisco. The team is launching a Healthy Soil Guide for chefs and home cooks about they can play in promoting healthy soils and climate solutions. CFS has also released a short film today called “Chefs for Soil,” which includes Myint and Leibowitz discussing their climate-friendly restaurant; that film is embedded below.

You’re a couple of city-dwelling restaurateurs with businesses in San Francisco and Manhattan—how did you find out about the connection between healthy soil and a stable climate?

Karen Leibowitz: We’d been working together in the restaurant business for a few years, starting with Mission Chinese Food and Commonwealth, both in San Francisco, when we had a daughter and started to think more concretely about the future with a capital F. That’s when we realized what a big impact the food system has on climate. We committed to the idea of making a sustainable restaurant, and when a friend of ours suggested we visit a rancher in Marin County—John Wick [of the Marin Carbon Project], who pretty much blew our minds.

Anthony Myint: John talked a mile a minute and offered us a reason to feel hopeful for the first time in our lives about reversing climate change. He explained the importance of perennial plants, particularly grasses, to “drawing down” carbon dioxide and return it to the soil, and we got so excited. We were still on our way home from Wick’s ranch when we decided to name our latest restaurant The Perennial.

Healthy Soils Program: Diversity of Farms Awarded, Cover Crops and Compost Most Popular Practices

Author: Brian Shobe | Published: December 13, 2017

The California Department of Food and Agriculture (CDFA) announced its first round of grants for the Healthy Soils Program last week. In our first blogpost about the awards, we shared a summary of the awards by project type (incentives versus demonstration) and a breakdown of the awards by county. In this blogpost, we share a preliminary analysis of the distribution of the awards based on land use type and the practices projects plan to adopt.

This preliminary analysis is based on our interpretations[i] of the one-paragraph project descriptions provided by applicants, which you can read here:

Incentives Projects

The 64 incentives projects are fairly well distributed across the major agricultural land use categories in California, with a quarter of the awards going to orchards, a quarter to annual cropland, and 13-14% each to vineyards, grazing/range lands, and mixed land use operations. Nine percent of project descriptions were too vague to determine their land use.

We were excited to learn that nearly three out of four projects awarded will be adopting more than one practice; furthermore, nearly one in four projects will be adopting four or more practices! Numerous studies have demonstrated that combining Healthy Soils practices has a synergistic effect on soil health and GHG emissions.

Cover cropping is by far the most popular practice with more than half (39) of the projects planning to adopt it. Compost applications to perennial crops (21) and annual crops (18), mulching (14), and hedgerow planting (16) are also quite popular, with more than a quarter of projects including those practices. The “herbaceous cover practices” (e.g. contour buffer strips, field border, filter strip, etc.) seemed to be the least popular, with at best a handful of projects planning to adopt those practices. However, it is important to remember that in order to be eligible for any of the “herbaceous or woody cover practices,” an applicant had to adopt or maintain an existing “soil management practice.” This likely prevented some farmers and ranchers who were interested solely in the “herbaceous or woody practices” from applying.

New Research: Synthetic Nitrogen Destroys Soil Carbon, Undermines Soil Health

Author: Tom Philpott | February 24, 2010

“Fertilizer is good for the father and bad for the sons.”
–Dutch saying

For all of its ecological baggage, synthetic nitrogen does one good deed for the environment: it helps build carbon in soil. At least, that’s what scientists have assumed for decades.

If that were true, it would count as a major environmental benefit of synthetic N use. At a time of climate chaos and ever-growing global greenhouse gas emissions, anything that helps vast swaths of farmland sponge up carbon would be a stabilizing force. Moreover, carbon-rich soils store nutrients and have the potential to remain fertile over time–a boon for future generations.

The case for synthetic N as a climate stabilizer goes like this. Dousing farm fields with synthetic nitrogen makes plants grow bigger and faster. As plants grow, they pull carbon dioxide from the air. Some of the plant is harvested as crop, but the rest–the residue–stays in the field and ultimately becomes soil. In this way, some of the carbon gobbled up by those N-enhanced plants stays in the ground and out of the atmosphere.

Well, that logic has come under fierce challenge from a team of University of Illinois researchers led by professors Richard Mulvaney, Saeed Khan, and Tim Ellsworth. In two recent papers (see here and here) the trio argues that the net effect of synthetic nitrogen use is to reduce soil’s organic matter content. Why? Because, they posit, nitrogen fertilizer stimulates soil microbes, which feast on organic matter. Over time, the impact of this enhanced microbial appetite outweighs the benefits of more crop residues.

And their analysis gets more alarming. Synthetic nitrogen use, they argue, creates a kind of treadmill effect. As organic matter dissipates, soil’s ability to store organic nitrogen declines. A large amount of nitrogen then leaches away, fouling ground water in the form of nitrates, and entering the atmosphere as nitrous oxide (N2O), a greenhouse gas with some 300 times the heat-trapping power of carbon dioxide. In turn, with its ability to store organic nitrogen compromised, only one thing can help heavily fertilized farmland keep cranking out monster yields: more additions of synthetic N.

The loss of organic matter has other ill effects, the researchers say. Injured soil becomes prone to compaction, which makes it vulnerable to runoff and erosion and limits the growth of stabilizing plant roots. Worse yet, soil has a harder time holding water, making it ever more reliant on irrigation. As water becomes scarcer, this consequence of widespread synthetic N use will become more and more challenging.

In short, “the soil is bleeding,” Mulvaney told me in an interview.

Experiencing a Healthy Ecosystem in Spanish Altiplano

Author: Ashleigh Brown | Published: November 6, 2017

I have been in the remote area of the Murcian Altiplano for two months. It has been a life changing experience, living in an area so degraded. Every day the sheep walk past our bedroom window, followed closely by a huge cloud of dust that used to be fertile soil. You notice the dryness everywhere. My skin, hair, throat, everything feels parched, desperate for moisture. And the reasons for this dryness are everywhere too. Huge ploughs litter the farm, and it is a regular sight to see tractors, pulling these ploughs in the fields, also surrounded by huge clouds of dust.

All the life in the soil died long ago. Going for a walk around these parts is a surreal experience. It is often deafeningly quiet, it almost doesn’t seem real.

However, there are still small patches of land that have not been ploughed or over grazed. They are mini oases, where rivers flow, birds sing, butterflies flutter by, and wild boar roam. These patches give me a sense of what the damaged land could become, and motivate me to get up in the morning and continue with this mission.

Last weekend, we decided to venture into one of the largest patches of in-tact land in the area, a small mountain which the locals call ‘El Gato’ (the cat). We left the house just after dawn, and travelled as the sun rose to the foot of the mountain.

To get there, we had to walk across ploughed fields, with soil as pale and fine as sand. However, once we got to the foot of the mountain, Spanish Oak trees, surrounding by wild juniper, rosemary, thyme and a host of other plants were happily growing, giving homes to birds, insects, wild boar, squirrels, partridges, and more.

The Ground Beneath Our Feet

Published: December 4, 2017

During a major soil catastrophe — the Dust Bowl — President Franklin Roosevelt told state governors, “The nation that destroys its soil destroys itself.”

Still, we treat our soil like dirt. By growing food and storing carbon dioxide and water, the loam and peat that coats the earth sustains us all. In return, we till it, treat it with chemicals and generally walk all over it.

Without healthy soil, food becomes less nutritious and crops become harder to grow. If the crops aren’t healthy, then the 70 percent of the world’s fresh water that’s used for agriculture will be wasted.

2012 study found that about a third of the planet’s topsoil is degraded and that without action, the world will be out of soil suitable for farming within 60 years.

Why Fungi Rule the World

While many people associate fungi with mushrooms alone, those familiar stems and caps are merely the fruit, like an apple on a tree. The real action is underground.

Author: Barbara Moran | Published: November 2016

alking through the woods with Jennifer Talbot (CAS’04) means seeing the forest with fresh eyes. But not the way you might think. Those tall, trembling pines stretching into the azure sky? Meh. The autumn sunlight dappling the canopy? Whatever.

The stick stippled with brown and white rot?

“Oh, YEAH!” shouts Talbot, stooping to grab the crumbly branch from the forest floor. She points to a cluster of gelatinous yellow blobs on the bark—a fungus called witches’ butter. “We used to think this was a slime mold, but it isn’t,” she says, pausing to admire the goo. “It’s actually edible, if you want to go there.”

For Talbot, all the action is underfoot. The assistant professor of biology studies a group of organisms called mycorrhizal fungi, which infect the root tips of over 90 percent of plant families on earth—in a good way. The fungi supply nutrients to the plants and get food in return. “The vast majority of plants you see outside could not live where they do without mycorrhizal fungi in the soil,” says Talbot.

Mycorrhizal fungi also have an outsize role in the decomposition of dead plants and the release of carbon. And since Earth’s soil contains more than three times as much carbon as its atmosphere, what fungi do in the soil could dramatically affect climate change. But nobody knows exactly how, and climate models are woefully fungus-free. Talbot, trained in analytical chemistry and working in biology, is particularly well positioned to fill this knowledge gap, and she’s using genetic sequencing, computer modeling, and ecosystem measurements to uncover fungi’s role. Kathleen Treseder, a professor of ecology and evolutionary biology at the University of California, Irvine, and Talbot’s PhD advisor, says Talbot is “doing stuff that no one else can do.”

One conclusion: humans have underestimated the humble fungi. Not Talbot. As she puts it, “Mycorrhizal fungi are running the world.”

‘Re(store) It’: Green America Launches Campaign On World Soil Day To Save The Earth … Literally

Author: Green America | Published: December 5, 2017

WASHINGTONDec. 5, 2017 /PRNewswire-USNewswire/ — Green America today launched the Re(store) It campaign to educate the public and U.S. corporations about the benefits of regenerative agriculture, an approach to farming which uses methods that rejuvenate the soil and trap greenhouse gases. The campaign will educate consumers about the importance of regenerative agriculture and offer ways to support it.

 

“We are in a farming crisis and we can no longer continue with our current industrialized, chemical-intensive system of agriculture,” said Anna Meyer, the food campaigns director at Green America. “If we want to sustain farming for future generations and reverse climate change, we must save the soil by adopting regenerative practices.”

“We have already seen the power of consumer voice to push for more organic and non-GMO products,” said Jes Walton, food campaigns specialist at Green America. “Now it is time for consumers to demand a major shift in our food system and push for the mass adoption of regenerative agriculture, which has the potential for even more widespread benefits.”

Regenerative agriculture harnesses the relationships between plants and soil microbes to pull excess carbon dioxide out of the atmosphere and store it in plants and soils where it is a useful nutrient for farmers. These farming methods of storing carbon and re(storing) agricultural soils include: 

  • Crop Rotation and Cover Cropping 
  • Composting
  • Zero to Low Tillage and Mulching
  • Planting Perennials and Diverse Crops 

The Re(store) It campaign will release a series of blogs on topics ranging from carbon farming to Christmas Trees, all available at https://www.greenamerica.org/restore-it. The campaign will help individuals to promote regenerative agriculture in their communities, support farmers who are leaders in restoring soil health, and encourage food companies to support regenerative agriculture through their supply chains.

Regenerative Agriculture Is Essential to Our Sustainability Goals

Iain Watt shares signs of momentum in regenerative agriculture, and calls for greater commitment from corporates.

Author: Iain Watt | Published: December 4, 2017

In amongst all the worrying trends and ominous signals that keep us on our toes here at Forum for the Futurethe potential for the world’s soils to suck up some of the excess carbon that’s currently making mischief in the atmosphere shines as a genuine ray of hope.

The various approaches and technologies that might be used to return carbon to the planet’s soils (from no-till agriculture; through compost- and biochar-application; to agro-forestry and innovative livestock rotation practices) also promise a wide range of further benefits — from improved soil health through to better water management, via a significant boost to biodiversity.

Moreover, if we embrace an approach that treats farmers, rural communities and indigenous peoples fairly, and which ensures a living wage, we move into win-win-win territory.

All of which means that regenerative agriculture — agriculture which aims to put more into the environment and society than it takes out — is now near the top of the list of things that society should be exploring and embracing.

Regenerative agriculture takes advantage of soil as a carbon sink, improves soil quality, and produces more nutritious food in ways that make it not only better for the people who consume it, but also for those working to produce it.
