trees

I have a few decorative items on my desk at work, and some of those are longleaf pine cones. Even though I only learned of the rare longleaf pine forest – and the large pine cones that fall in them each year – a few years ago, it was love at first sight.

Longleaf pine forests once covered the coastal landscape of the Southeast, and they’re home to nearly 600 plant and animal species.

But over the past two centuries, development, timbering and fire suppression reduced the longleaf's range by almost 97 percent. And many groups, including USDA’s Natural Resources Conservation Service (NRCS), are working to save and restore this landscape. According to the America’s Longleaf Restoration Initiative, longleaf forests have increased from about 3 million acres to about 4.4 million acres in recent years, reversing a century-long decline across the region.

Two million seedlings will grow up one day to become the forests of our future.

The vision for all of those trees is part of the mission of the Charles E. Bessey Nursery, part of the Nebraska National Forests and Grasslands, and the oldest federal seedling nursery in the nation.

Working with the Bessey Ranger District and the volunteer group Friends of the Nebraska National Forests, the nursery recently invited the public in for a rare opportunity to see the nursery in full production; growing, packing and shipping hundreds of thousands of seedlings to U.S. Forest Service, Bureau of Land Management, conservation districts and other government agency locations. The seedlings are used for reforestation following fire and insect infestations, wildlife/habitat plantings, wind breaks, conservation plantings, and general planting.

Nature has transformers! With time and the help of bees, butterflies, birds and other critters, some flowers change into seeds. Sometimes, flowers in trees transform into nuts.

But sometimes these transformers need help. That’s where a Conservation Innovation Grant from USDA’s Natural Resources Conservation Service to The American Chestnut Foundation came into play.

The foundation competed for and was awarded a grant from NRCS to plant and grow genetically diverse, blight-resistant chestnuts and other high quality hardwoods to reintroduce and maintain forests on reclaimed mine sites in Appalachia.  The American chestnut trees were once common, but, nearly vanished from the landscape because of an accidentally introduced fungus in the late 1800s.

Over the past several years, we have seen the spread and occurrence of wildfires increase significantly. Deadly wildfires threaten our homes and communities and turn lives upside down.

USDA continues to do all that we can to protect people, homes and our forests in the face of fire. Just this week, we announced four new airtanker additions to the U.S. Forest Service’s next-generation firefighting fleet, which brings the total amount of aircraft to 21 large air tankers (with opportunities to add additional aircraft, if needed) and more than 100 helicopters. These new aircraft will enter service in the coming weeks and support over 10,000 firefighters during this year’s wildfire season.

One of the things I consider a highlight of my career and that I will always remember is our successful response to the July 2010 detection of the Asian longhorned beetle (ALB) in Boston, Massachusetts.  As I attended the May 12 ceremony commemorating the eradication of the ALB infestation in Boston and listened to the speakers share their thoughts about what it took to get us there, I had a deep sense of appreciation for the partnership among the state and federal cooperators who worked together to bring us to that day.  It was swift action and continued diligence that protected Boston’s trees from further destruction.

APHIS and its cooperators were able to accomplish the goal of eradicating ALB in Boston in less than 4 years.  Thanks also go to a community member who reported the infestation early.  That early detection and report resulted in the loss of only 6 infested trees.

But as I celebrate our first victory over the invasive pest in Massachusetts, I am compelled to ask you to remain vigilant in inspecting your trees regularly for signs of the beetle and report any suspicious damage to your State Plant Health Director.

It’s Clean Air Month, and roadside trees are cleaning the air and helping us feel better.

If you live in an area where there’s a lot of people and traffic, air quality may have crossed your mind at one point or another—and rightly so. In recent years, the health of people living, working or going to school near roads with high traffic volume has been a quickly rising national concern. All over the world, studies are finding air pollution levels especially elevated in these areas.

A multidisciplinary group of researchers, planners and policymakers from the U.S. Environmental Protection Agency, U.S. Forest Service and other organizations found that strategically planting trees near busy roadways may significantly enhance air quality. Their findings were published last year in the Transportation Research Board magazine.

This month USDA will be highlighting the value of conservation with a different focus each week.

Sometimes the benefits of conservation can be abstract. For example, think a minute about the dollar value of a single tree. Can you come up with a number?

Did you consider that the tree creates oxygen, captures carbon and provides wildlife habitat? Or that the tree serves as a windbreak, shades and cools the surrounding area, and improves water quality? Don't forget, these benefits extend for many decades over the lifetime of a healthy tree.

Residents of the Appalachian Mountains of the eastern United States have long enjoyed a rich culture of storytelling. Often rooted in a deep connection to the natural world, stories from Appalachian folklore serve to entertain as well as to educate; sometimes, important life lessons emerge, especially from tales of demise. A present-day ghost story from the southern Appalachians has captured the attention of U.S. Forest Service researchers who are using high-tech tools to follow the footprints of lost life.

The ghosts in this story are eastern and Carolina hemlock trees. Hemlocks provide valuable ecosystem services in Appalachian forests, including cover for wildlife and cooling shade along waterways. But they are being killed in increasing numbers by an exotic invasive insect, the hemlock woolly adelgid. Native to Asia, the hemlock woolly adelgid is transported through forests by animals, wind and, accidentally, by people. Often called “gray ghosts” because of their pale, skeleton-like appearance, the dead hemlocks are obvious across the mountain landscape. Using a forest monitoring tool known as ForWarn, scientists are able to see just how devastating the hemlock losses have become across the southern Appalachians, where the hemlock woolly adelgid thrives in the warmer temperatures. Here, the hemlock woolly adelgid is killing trees much more quickly than in the more northern areas of the hemlocks’ range, sometimes in as few as four years after infestation.

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

A pine cone has many purposes. It could serve as a home for birds and insects. Pine cones contain seeds to use in reforestation projects. They even can be made into fanciful ornaments to adorn the 2014 Capitol Christmas Tree.

That’s exactly what students learned during a recent Science Fusion program at the Science Museum of Minnesota.

As part of an overarching mission to the world of science, technology, engineering and math, these special Saturday programs afford underserved Minnesota youth the opportunity to interact with local scientists, engineers, inventors and science educators through hands-on activities.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine, including research into trees that could fuel new energy solutions.

A team of researchers led by the University of California–Davis has mapped the complete genome of the loblolly pine. And if you don’t think that understanding the genetic makeup of loblolly pine is a big deal, perhaps you cannot see the forest for the trees.

Loblolly pine, the most commercially important tree in the United States, is the source of most paper products in this country and 58 percent of timber. On the surface, that might be reason enough for the USDA’s National Institute of Food and Agriculture (NIFA) to invest $14.6 million in 2011 toward science that could increase the productivity and health of American forests.
