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.
To raccoons, snakes and opossums, crayfish look pretty tasty, and large crayfish will even cannibalize their smaller kin. Crayfish, which live in rivers and streams, need instream cover to hide from all their predators. They also use cover to find food, to shelter while incubating eggs, and to keep themselves from being washed away in floods.
Susan Adams, a fisheries research scientist for the Forest Service’s Southern Research Station, examined different types of cover in the Yazoo River basin of Mississippi to see whether crayfish used large pieces of household trash for shelter when natural cover was limited. Her findings recently appeared in the journal Environmental Management. Read more »
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. Read more »
Warm Fire, 2006. Over the last three decades, fire season lengths have increased by 60-80 days and annual acreages burned have more than doubled to over 7 million acres annually. In addition, growing housing development in forests has put more people and houses in harms’ way, also making firefighting efforts more expensive.

Forests significantly contribute to our quality of life, but climate change is adversely affecting natural resources in rural and urban areas across the U.S. A new report released by the White House, the National Climate Assessment, explores many related issues including how a warming planet affects our forests.
With contributions from U.S. Forest Service scientists, the report is one of the most comprehensive examinations of climate change and its effects on forested land. It concludes that a warming climate will complicate future management of public, private and tribal forests. Read more »

The recent tragedy involving U.S. Forest Service Law Enforcement Officer Jason Crisp and his K-9 Maros brought to light the close bond between an officer and his dog and the dangers they face.
Crisp and K-9 Maros were killed in the line of duty on March 12, 2014 in Burke County, North Carolina. The efforts of officers and K-9s are crucial to the mission of Forest Service law enforcement and a well-trained K-9 team is vital to the protection of people, property and resources on U.S. Forest Service-managed lands. Not only are the highly trained dogs involved in the apprehension of suspects and the detection of narcotics, but they also locate evidence, track individuals and provide community demonstrations.

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.

Check into any hotel in Connecticut and look around the front desk or the gift shop, and you’ll see postcards with pictures familiar to all “Nutmeggers” – the ones that let Connecticut residents know they’re home. They often show scenic vistas filled with assorted shades of yellow, gold, and red of trees during fall – a paradise for the “Leaf Peeper.”
But it isn’t only about beauty. The residents of Connecticut depend on the state’s woodlands every day to build and heat homes, take hikes, observe wildlife and breathe air. We need the goods, service, and protection trees provide.
That’s why USDA’s Natural Resources Conservation Service (NRCS), U.S. Forest Service and other conservation partners work to protect forests. Read more »
