When winter weather arrives, most bats hibernate in caves, but a few species migrate to warmer areas. Warmer being relative, the migrating bats may still end up in places that are too cold for comfort, and sometimes hibernate under leaf litter for short periods of time.
Roger Perry, a wildlife biologist at the U.S. Forest Service’s Southern Research Station, studied these temporary hibernation sites to find out how much protection they offered bats, and how much energy bats expend to stay alive.
The leaf litter study took place in and around the Alum Creek Experimental Forest of the Ouachita National Forest in Arkansas, and focuses on eastern red bats, a migratory species that remains active through most of the winter. When winter temperatures are not too cold the bats roost in trees, but when temperatures plunge, the bats temporarily hibernate underneath leaf litter. Read more »

Note: Three projects funded by a USDA Conservation Innovation Grant were recently honored by the American Carbon Registry for innovative approaches to environmental stewardship. The winners included Ducks Unlimited, Delta Institute and Terra Global Capital. Ducks Unlimited’s work aimed to generate a carbon credit system for North Dakota landowners, which not only reduces greenhouse gas emissions but also restores wetlands and grasslands that are crucial to waterfowl. Delta Institute is working with farmers to reduce use of nitrogen – one of the largest sources of greenhouse gas emissions. Finally, Terra Global Capital and many others partners are working on a credit system for rice growers in California and the Midsouth. The below post provides more information on this project.
USDA is helping to provide rice growers in California and the Midsouth with new opportunities to voluntarily execute conservation practices that reduce greenhouse gas emissions while cultivating a new income stream.
The California and Midsouth rice projects are funded by a Conservation Innovation Grant from USDA’s Natural Resources Conservation Service, which is providing more than $1 million to help identify and develop new conservation methods. The grant also leverages new and emerging ecosystem income for landowners while addressing climate change. Read more »

Rice producers recently honored Dave White, former chief of USDA’s Natural Resources Conservation Service, for his innovative conservation achievements.
White was presented with the fourth annual USA Rice Federations’ Distinguished Conservation Achievement Award at the 2013 USA Rice Outlook Conference held in Saint Louis, Mo.
“Dave worked very closely with the rice industry during his tenure as NRCS chief,” said Leo LaGrande, a California rice producer and chairman of the USA Rice Producers’ Group conservation committee. “His vision and foresight led to the development and implementation of the Migratory Bird Habitat Initiative (MBHI) in several mid-South and Gulf of Mexico coastal states, including the five rice-producing states of Arkansas, Louisiana, Mississippi, Missouri and Texas.” 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 »
Stanley Lee has put more efficient light bulbs in his chicken houses and made other updates that lower his carbon footprint.
It can take a lot of energy to raise chickens as farmers have to control the temperature and lighting in houses, meaning high costs and high energy use.
But with help from USDA’s Natural Resources Conservation Service, poultry producers can cut their costs while conserving energy.
One Benton County, Ark. producer is cutting his gas and electric bills while decreasing greenhouse gas emissions. Stanley Lee did this by installing radiant heaters, light-emitting diode light bulbs, or LEDs, and attic insulation in his six chicken houses that shelter 890,000 chickens each year. Read more »

2013 is the International Year of Statistics. As part of this global event, every month this year USDA’s National Agricultural Statistics Service will profile careers of individuals who are making significant contributions to improve agricultural statistics in the United States.
Growing up in Texas, you’re never far removed from agriculture. Even though I grew up in Houston, my grandparents had a beef operation and I’ve always believed that agriculture is simply in my blood. I also knew that I had a passion for numbers, so when time came for me to pick a college major, Agricultural Economics seemed like a great combination of my two passions.
I earned my degree from Prairie View A&M University in Texas. During my junior year, I joined USDA’s National Agricultural Statistics Service (NASS) Texas Field Office as an intern, which ended up transforming into a full time position with the agency’s Arkansas office after my graduation.
