Nature High Summer Camp Connects Young People, Natural Resource Professionals

USDA Blog Post:

Sierra Hellstrom, Nature High Summer Camp director, explains to student about the core sample taken from an aspen tree.
Sierra Hellstrom, Nature High Summer Camp director, explains to student about the core sample taken from an aspen tree.
In a few short years, high school students at Nature High Summer Camp on the Manti-LaSal National Forest in Utah may become newly minted natural resource professionals who make a difference in the world of natural resources.
The 30 high-school students from Utah met as strangers on a Monday morning, but left Saturday as good friends who connected with nature in a way they had never before experienced.
“It’s amazing to see the changes in the students over the course of a week,” said Sierra Hellstrom, camp director who works in the U.S. Forest Service’s Intermountain Region. “They arrive shy and scared, with little knowledge of public land management. They leave enlightened and a very tight-knit group, and have a hard time saying goodbye to one another.”
The 22-year-old camp, a partnership with several government agencies, introduces students to “a day in the life” of a natural resource professional to learn about the complexities of public land management.
They work with silviculturists – or forester – to learn how to core trees to gather information on the age of stands (grouping of trees), health of trees, and other vital information.
Working with biologists, students learn about aquatic insects and how their presence – or absence – can reveal water quality. Students don waders and spend a morning catching samples in nets to identify and then interpret what they have discovered and how that relates to the entire watershed.

A soil scientist helps the students get literally dirty by digging a plot of soil so they can study the layers, the health of the surrounding area and other variables that affect how the soil is compacted.
A hydrologist and students carrying high-tech instruments wade into the water to test stream flow, temperature and other factors to determine spring run-off numbers and how they will affect the water supply throughout the summer.
Then they hike through the forest with an entomologist to learn that a very small insect – a bark beetle – in large numbers and under the right conditions can kill millions of trees. The students collect insect samples then return to camp to study them.
The students, by working in the field with professionals, also learn how science contributes to public policy and the eventual decisions that shape the public’s use of 193 million acres of national forests and grasslands.
“We cram a lot into a small period of time,” Hellstrom said. “But each segment is important. We can only hope that during that week we planted a seed in the minds of these young people who may see natural resources as a viable career choice. At the very least, we hope that they grow into adults who understand the connection between the natural world and our everyday lives.”
The success of camp is also measured by how many students eventually find internships, summer work or volunteer opportunities with natural resource agencies.
Perhaps the success of the program can best be summed up with a written critique from a camper: “I have a new outlook on life and people in general. We really can make a difference.”

Celebrating Grey Towers' Golden Anniversary

A beautiful, blue stone mansion with its slate roof and turrets, known as Grey Towers, in Milford, Pa. has been a sanctuary for visitors from around the world to learn about conservation and natural resources.
Fifty years ago on Sept. 24, 1963, President John F. Kennedy dedicated the Grey Towers National Historic Site and the Pinchot Institute for Conservation Studies as a “living memorial” to America’s first forester and two-term Pennsylvania governor, Gifford Pinchot.
On Sept. 19-22, the Forest Service, the Pinchot Institute and the Grey Towers Heritage Association will celebrate Grey Towers’ golden anniversary with public and private events, receptions, lectures, honored guest speakers, public visitation and family programs. This commemoration is an opportunity for the Forest Service, and its partners and collaborators to celebrate Pinchot’s legacy and highlight the many contributions he made to the Forest Service and beyond. What better way to honor the conservation legacy of the father of American conservation than by offering the Pinchot home as a public center for tours, meetings, study and research.

The historical Grey Towers was first completed in 1886. Eight decades later, the site was designated as a National Historic Landmark. In 1980, more than $16 million in federal, state, and private funds were raised to complete a comprehensive restoration of the historic features and the renovation of the building and estate for “adaptive re-use” as a world-class conference center.  The Pinchot Institute for Conservation Studies, which was established on this site, has served as a center for today’s most challenging environmental issues.

The Forest Service, along with its partners, is carrying out Pinchot’s legacy of “practical idealism,” and his philosophy that in order to be effective, natural resource conservation must be not only ecologically sound, but economically viable and socially responsible. To this day, Pinchot’s philosophy of providing “the greatest good for the greatest number in the long run” is the driving principle behind the Forest Service’s approach to natural resources management.

Back to School with Statistics, Join USDA's Virtual Open House

USDA Blog Post:

A new academic year is here for millions of students and teachers across the country, and in spirit of the many back to school nights and open houses taking place, I’m encouraging you to explore USDA’s International Year of Statistics Virtual Open House.
The International Year of Statistics, sponsored by more than 2,000 organizations – including the USDA – is a worldwide event to help teach everyone about the powerful and far-reaching effects of statistics. When people hear the word “statistics,” they often think of sports statistics or the course they took and struggled to pass. While you can think of statistics in these terms, there is more to the relationship between you and statistics than you may imagine.
For agriculture, did you ever wonder about where your food is raised, how it’s produced, and by whom? How this information impacts future food prices and availability? About weather patterns and climate change and the effects they have on crops, livestock and America’s farm land? These questions and many more can be answered with statistics that are produced by USDA.
Statistics are rewarding to us not only as statisticians, economists and researchers, but also as students, teachers, parents and consumers. They arm us with the knowledge to contribute to the wellbeing of the entire human race – the people living with us at home, to our neighbors in nearby communities, to strangers we’ve never met around the globe.
Because of agricultural statistics we can make informed buying decisions for our families, we can impact societal change by supporting U.S. farm and rural policy, and we can make strides for the future by encouraging young minds to explore careers in statistics, mathematics and science.
Join the USDA’s International Year of Statistics Virtual Open House today by exploring the National Agricultural Statistics Service (NASS), the Economic Research Service (ERS) and the World Agricultural Outlook Board online. Touring these online sites, you can discover statistics, data tools and research, including:
  • Ag and Food Statistics: Charting the Essentials explores the basics of farm and food sectors with 75 charts and maps.
  • Amber Waves presents the economics of food, farming, natural resources and rural America in lay terms via engaging features, findings, and statistics.
  • CropScape, a data visualization and analysis tool with satellite derived land cover images showing the annual planted crops and the ever-changing impacts on U.S. agriculture.
  • Food Security Information and research that is helping provide access by all people at all times to enough food for an active, healthy life.
  • Quick Stats 2.0, the most comprehensive tool for accessing agricultural data published by NASS that allows you to visualize, manipulate, and export exactly the information you desire, whether it is based on commodity, location, or time period.
  • World Agricultural Supply and Demand Estimates reports which shows U.S. farmers, policymakers, and traders what’s going on in the world of farm commodity forecasts at a single moment in time.
If you have a question, you can also connect with us on Twitter by tweeting NASS (@usda_nass) and ERS (@usda_ers). Join our virtual open house today and learn how agricultural statistics enhance the work of USDA and your life – every day and in every way!

Russell Wire, a northwest Illinois farmer, found cover crops to be an excellent option for his operation. His cattle enjoy grazing quality forage, and his soil health is improving as well.
At age 8, Russell Wire knew he liked agriculture. That was when he raised some beef cattle for a 4-H project, eventually turning that project into a herd of 40.
This natural affinity makes sense—Wire, who lives in northwest Illinois, comes from a farm family. The 28-year-old is actually a fifth-generation farmer.
Since 2005, Wire has worked 40 acres of pastureland, and he’s grown corn on another 50 acres since 2011. Recently he decided to incorporate cover crops into his operation to provide more forage for his herd, prevent erosion and improve soil health.
He sought guidance from specialists at USDA’s Natural Resources Conservation Service to help make decisions and plans for successfully growing and managing cover crops.
Late summer 2012 was Wire’s first year planting cover crops. He opted for a mix of annual ryegrass and tillage radish. He likes the fact that he is able to do something different for a conservation solution that will sustain his operation.
Wire used a no-till drill to seed the radishes. While the right soil temperatures are important for success, 2012’s drought conditions threatened good seed germination. Luckily, a late September rain saved the day and he was able to grow a good, healthy cover crop.
At the same time, Wire allowed forage on his pastures to grow to a height of about 20 to 24 inches. This made high moisture haylage available for the herd.
Because of the pasture’s location, he uses his cropland to grow hay instead of using it for livestock grazing. He cuts the forage when it’s ready, then bales it for later use.
According to Wire, the best part about cover crops is that they improve the health of his soil. He’s also happy to see fewer weeds due to the annual ryegrass’ dense foliage.
He’s found that the radishes effectively break up soil compaction and bring valuable nutrients back to the surface for other crops to use.
Wire is pleased with the results of his new techniques. He can watch his cover crops grow, provide quality hay and feed for his cattle, and hold back erosion. And he’s a pioneer in his area.
“A lot of people are watching me to see how it works,” he says.

An Interest Rate Cut Will Do Little to Solve Greek Budget Trouble - SPIEGEL ONLINE

In August, Merkel's government admitted that Greece needs billions of euros in additional aid. Some have called for a cut to interest rates on emergency loans made to Greece. But with the rates already so low, it would be but a drop in the bucket.

Forest Service Reaches Latinos through Legacy Program

USDA Blog Post:

More than 1,500 inner-city youth from Houston Independent School District gather over a week-long period at Jones State Forest – Children’s Forest each year to participate in the annual Exploring Houston’s Backyard. The Bosque Móvil-Forest Mobile is one tool the U.S. Forest Service’s Latino Legacy program uses to provide learning experience around Texas.
More than 1,500 inner-city youth from Houston Independent School District gather over a week-long period at Jones State Forest – Children’s Forest each year to participate in the annual Exploring Houston’s Backyard. The Bosque Móvil-Forest Mobile is one tool the U.S. Forest Service’s Latino Legacy program uses to provide learning experience around Texas.
Roughly a decade ago, Tamberly Conway impulsively agreed to leave Key West, Fla., with a friend to serve as crew members on a 47-foot sailboat with a captain they barely knew. But somewhere between Key West and Guatemala, she began reevaluating her decision.
They got off the boat in Guatemala and spent the next year absorbing the Latino culture and Spanish language. She turned that unexpected experience into helping the U.S. Forest Service reach out to the Latino community. Along with her multiple degrees in natural resources, Conway connects Latinos to the natural world around them through such programs as Latino Legacy.
“These programs provide avenues for students who gradually gain a sense of empowerment,” Conway said. “They understand that it’s okay to be a leader in this arena and help their community understand the need to take care of the land and conserve what they have. I tell them, ‘You can be leaders in this area so you can improve your nation’s food sources and make sure we have enough wood, water and wildlife in the future.’”
Stationed in Texas, Conway’s first project after joining the Forest Service five years ago centered on development of the Latino Legacy program, created in large part through a More Kids in the Woods cost-share initiative and partnership funds. Latino Legacy program goals are to develop, implement and evaluate culturally appropriate conservation education programs designed for urban and rural Latino communities. It has since evolved into a hub for a number of programs focusing on diversity outreach and conservation education.
Forest Service conservation education specialist Tamberly Conway talks about how to use binoculars for wildlife viewing to members of the Chikawa-Aztec Cultural Troupe during the Wild About Wings program at Jones State Park in Texas.

The two primary outreach tools are the “Bosque Movil,” or forest mobile, a mobile information and activity station, and the “Amigos de Bosque,” or the Friends of the Forest, a semi-bilingual conservation education and community outreach team, managed by the Friends of the National Forests and Grasslands in Texas.
The Friends organization was formed to help the Forest Service make the 600,000 acres of forests and grasslands in that state more accessible to diverse audiences. Together with strong partners like the Texas A&M Forest and Stephen F. Austin State University, the program has reached at least 250,000 people, although some supporters believe the number to be more than double that amount.
“We are able to go into schools that have high populations of Latinos and engage not only the students but also educators, administrators, parents and community partners,” she said. “Our work helps create a pathway to something more. Whether these youth choose to work in natural resources or not, they have a new excitement about the outdoors, and they share that excitement with others in their communities.  They are becoming our current and future conservation leaders.”
Conway’s next project, in a USFS partnership with a Project Learning Tree grass-roots program called Green Schools!, will result in a national model that will target early childhood through high school in an educational feeder pattern or “grapevine,” with a strong focus upon higher education and possible futures in natural resource careers.  The Green Schools! initiative helps students improve communication, civic and leadership skills, while increasing environmental awareness. The pilot project will focus on the East End community in Houston and the Houston Independent School District, which are predominantly Latino.

This week at USDA we are celebrating National Health IT week by highlighting USDA’s ongoing efforts to expand modern health care access to rural America. Yesterday, we announced two new steps to improve health care for rural Americans – both through new investments in health infrastructure and ongoing interagency partnerships designed to better focus Federal efforts on rural health care.
USDA is expanding a partnership with HHS and the Department of Veterans Affairs, as part of our work together on the White House Rural Council, to leverage funds and other efforts that will support advanced health care technology in rural hospitals. This partnership is an extension of a successful pilot launched in five states – Illinois, Iowa, Kansas, Mississippi and Texas – to identify rural critical access hospitals in persistent poverty areas in need of advanced health care technology. For example, during the pilot phase of this partnership, the USDA Rural Development Iowa State Office, the Iowa Regional Health IT Extension Center (REC) and the Iowa State Office of Rural Health convened the first Iowa Rural Health IT Forum to expand care for Critical Access Hospitals.
Meanwhile, we are continuing to let folks know about HHS and VA health care initiatives. This has included the Department of Veterans Affairs Rural Veterans Coordination Pilot Program, to empower rural organizations in promoting high-quality health care and mental health services for our veterans. And last week, The Department of Health and Human Services Office of Rural Health Policy announced grants to build telehealth networks, delivering mental health services to rural veterans as well as funds that will recruit and train a workforce with expertise in Health IT.
We also continue to strengthen partnerships with rural communities by investing in high-quality health care infrastructure. Yesterday, USDA announced loans and grants that will help improve health care facilities – providing assistance with everything from building a new critical access hospital building, to modernizing surgical equipment and improving patient registration. These new investments complement efforts that USDA has already made, since 2009, that have expanded distance health care tools to more than 1,600 health care institutions and provided support for more than 1,000 health care facilities.
All of these efforts are helping to create a modern health care infrastructure to better serve rural Americans. At the same time, we are working together to be sure that all Americans have access to affordable health care – in particular by reminding folks across the nation that new opportunities for coverage under the Affordable Care Act will soon be available through new Health Insurance Marketplaces. Beginning in 2014, more than 7.8 million uninsured rural Americans under age 65 will have new opportunities to enroll in affordable health care.
This is critically important in rural America, where nearly one in five uninsured Americans lives and where a greater share of residents lack health insurance.  A large proportion of folks in rural America will be eligible for discounted insurance coverage through their states’ Health Insurance Marketplaces, so we’ll continue helping to get the word out in rural America. The Department of Health and Human Services provides a wide range of information on the benefits of the Affordable Care Act – and how to obtain coverage if you’re not insured – on www.healthcare.gov.
Rural America faces unique barriers to health care, but together we can meet these challenges. I’m looking forward to continuing USDA’s work alongside our interagency partners that will further expand health care for rural Americans in generations to come.

In Water as In Love, Likes Can Attract

This model of the guanidinium chloride salt (blue and silver) in solution shows carbon (yellow) and water (green) surrounding the cations and demonstrates cation-cation pairing.
At some point in elementary school you were shown that opposite charges attract and like charges repel. This is a universal scientific truth – except when it isn’t. A research team led by Berkeley Lab chemist Richard Saykally and theorist David Prendergast, working at the Advanced Light Source (ALS), has shown that, when hydrated in water, positively charged ions (cations) can actually pair up with one another.
“Through a combination of X-ray spectroscopy, liquid microjets and first principles’ theory, we’ve observed and characterized contact pairing between guanidinium cations in aqueous solution,” Saykally says. “Theorists have predicted this cation-to-cation pairing but it has never been definitively observed before. If guanidinium cations can pair this way, then other similar cation systems probably can too.”
Guanidinium is an ionic compound of hydrogen, nitrogen and carbon atoms whose salt – guanidinium chloride – is widely used by scientists to denature proteins for protein-folding studies. This practice dates back to the late 19th century when the Czech scientist Franz Hofmeister observed that cations such as guanidinium can pair with anions (negatively charged ions) in proteins to cause them to precipitate. The Hofmeister effect, which ranks ions on their ability to “salt-out” proteins, became a staple of protein research even though its mechanism has never been fully understood.
In 2006, Kim Collins of the University of Maryland proposed a “Law of Matching Water Affinities” to help explain “Hofmeister effects”. Collins’s proposal holds that the tendency of a cation and anion to form a contact pair is governed by how closely their hydration energies match, meaning how strongly the ions hold onto molecules of water. Saykally, who is a faculty scientist in Berkeley Lab’s Chemical Sciences Division and a professor of chemistry at the University of California Berkeley, devised a means of studying both the Law of Matching Water Affinities and Hofmeister effects. In 2000, he and his group incorporated liquid microjet technology into the high-vacuum experimental environment of ALS beamlines and used the combination to perform the first X-ray absorption spectroscopy measurements on liquid samples. This technique has since become a widely used research practice.
Berkeley Lab’s Rich Saykally has spent much of his career investigating the amazing chemistry of water.

“The XAS spectrum is generally sensitive to the changes in the local solvation environment around each atom, including potential effects of ion-pairing,” Saykally says. “However, the chemical information that one can extract from such experimental data alone is limited, so we interpret our spectra with a combination of molecular dynamics simulations and a first principles theory method.”
Development of this first principles theory method was led by Prendergast, a staff scientist in the Theory of Nanostructures Facility at Berkeley Lab’s Molecular Foundry. Computational resources were provided by the National Energy Research Scientific Computing Center (NERSC). The Molecular Foundry and NERSC, as well as the ALS, are all U.S. Department of Energy national user facilities hosted at Berkeley Lab.
With the liquid microjet technology, a sample rapidly flows through a fused silica capillary shaped to a finely tipped nozzle with an opening only a few micrometers in diameter. The resulting liquid beam travels a few centimeters in a vacuum chamber and is intersected by an X-ray beam then collected and condensed out. In analyzing their current results, which were obtained at ALS Beamline 8.0.1, the Berkeley Lab researchers concluded that the counterintuitive cation-cation pairing observed is driven by water-binding energy, as predicted by theory.
Orion Shih, a recent graduate of Saykally’s research group, is the lead author of a paper describing this study in the Journal of Chemical Physics. The paper is titled “Cation-cation contact pairing in water: Guanidinium.” Saykally is the corresponding author. Other co-authors are Alice England, Gregory Dallinger, Jacob  Smith, Kaitlin Duffey, Ronald Cohen and Prendergast.
“We found that the guanidinium ions form strong donor hydrogen bonds in the plane of the molecule, but weak acceptor hydrogen bonds with the pi electrons orthogonal to the plane,” Shih says. “When fluctuations bring the solvated ions near each other, the van der Waals attraction between the pi electron clouds squeezes out the weakly held water molecules, which move into the bulk solution and form much stronger hydrogen bonds with other water molecules. This release of the weakly interacting water molecules results in contact pairing between the guanidinium cations. We believe our observations may set a general precedent in which like charges attract becomes a new paradigm for aqueous solutions.”
