Although birch trees can’t literally walk, warming temperatures are causing a gradual migration of these and other tree and plant species to northern or higher elevation climates. USDA photo.
With large areas of our planet heating up because of climate change, some trees (and plants) are pulling up roots and heading north, to higher elevations and to cooling climes—well, sort of.
A U.S. Forest Service-led study suggests there are a few dozen tree species in the eastern U.S. that are moving north at an unexpected rate.
“For some plants and trees, moving north is real and their only chance for survival,” said Chris Woodall, a research forester for Northern Research Station and the study’s author. “Our study confirms a link between global warming and forest migration. It’s no longer conjecture.” Read more »
Tohono O’odham Community College occupational technology students receive hands-on training using solar demo trailer that is used to demonstrate different ways that solar energy can be used, including a passive solar hot water heater as shown on the roof of the trailer. The solar demo trailer is a mobile educational resource that is used throughout the schools and communities of the Tohono O'odham Nation in Arizona.
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 USDA’s rich science and research portfolio.
A man in Arizona threw away an extension cord – and that’s a big deal for some folks who live about 100 miles west of Tucson.
The 48 families who live in the Pisinemo District of the Tohono O’odham Nation reside in an area so remote that some had to get their power by stringing extension cords to a neighbor’s house. Now, however, they have new solar panels to provide electricity for heating, cooling, and cooking. Read more »
What do Tristan Reader of Tohono O’odham Community Action (TOCA), Amy Bacigalupo of the Land Stewardship Project in Minnesota, Haile Johnston of Common Market in Philadelphia and Michael Todd’s environmental studies class at Ames High School in Ames, IA have in common? They’re all building connections between farms and consumers and creating strong local food systems in their communities. And all joined me for a Google+ Hangout – a live, virtual panel – on Thursday, November 21 to discuss their work.
There is amazing energy surrounding the development of local food systems in communities nationwide, and our discussion certainly reflected that. But it also came at a time of uncertainty. Congress has yet to pass a Food, Farm and Jobs bill, the major piece of legislation funding USDA’s local food efforts (along with many other critical programs). Until a bill is passed, many of the key resources for producers, businesses and communities engaged in local food systems are without funding. That reality lent a sense of urgency to some of the topics we discussed. Read more »
The 88-foot Engelmann spruce selected as the 2013 Capitol Christmas Tree is hoisted onto a flatbed truck, where it will be secured for the 5,000-mile journey across the country. (U.S. Forest Service photo)
More than 300 people gathered on in 25-degree weather to witness the harvesting of the 88-foot 2013 Capitol Christmas Tree from the Colville National Forest, the first step in its 5,000 mile journey from Washington State to the U. S. Capitol in Washington, D.C.
More than a dozen spotters and equipment operators manipulated the tree into position as the Mack Truck pushed the trailer underneath. The enormity of the Engelmann spruce became apparent as the tree floated above the trailer while a few extra feet from the trunk had to be removed.
Every December, the Speaker of the House hosts a lighting ceremony on the U.S. Capitol grounds. With a simple flip of a switch roughly 10,000 lights bring the tree to life. But first it has to make the journey. Read more »
USDA Census shows healthy habits are taking root across the country.
When students have experiences such as tending a school garden or visiting a farm they’ll be more likely to make healthy choices in the cafeteria. And when schools invest their food dollars in their local communities, all of agriculture benefits, including local farmers, ranchers, fishermen, food processors and manufacturers.
Good news: these healthy habits are taking root all across the country.
USDA released today results from a nationwide Census of farm to school activities. We found that 43 percent of all public school districts have an existing farm to school program in place. Another 13 percent of school districts surveyed are committed to launching a farm to school program in the near future. With purchasing local food as a primary farm to school activity, in school year 2011-2012, schools purchased and served over $350 million in local food. Read more »
Newly installed pivot irrigation lines run behind Gerry Gonzalez, NRCS district conservationist in Douglas (left) and farmer Alfredo Zamora.
Travel 30 miles south of Alfredo and Sabrina Zamora’s farm in Cochise County, Ariz., and the imposing border fence between the U.S. and Mexico rises up across the horizon. This border county is rural, arid, open land where the Zamoras have spent their lives farming.
The couple is well known in the area for their cotton, pecans and alfalfa crops and they are no strangers at the local USDA Natural Resources Conservation Service office in Douglas. They’ve worked with NRCS over the years to plan out and implement conservation on their farm, including more efficient water and irrigation practices, the use of crop residue to improve soil health and the reduction of soil erosion.
