Invasive tree conquers South

in Morning Ag Clips

The tallow tree, a “super invader” with toxic leaves and no natural enemies in North America, is conquering the South.

Overtaking forests from Texas to Florida, tallows grow three times faster than most native hardwoods, and each one casts off 100,000 seeds a year. Controlled burns haven’t stopped their spread, nor have herbicide sprays from helicopters. Cutting them down works only when each stump is immediately doused with chemicals. Harvesting them for biofuel remains more a promise than a practical solution. Continue reading

Emerald ash borer may have met its match

In ARS News

By Sharon Durham

A wispy wasp may pack a potent punch in the fight against the emerald ash borer (EAB), an insect pest that causes catastrophic ash tree losses in the United States.

EAB has wings that are deep emerald green on the outer edge and a body underneath that’s iridescent magenta. Its stunning appearance belies the fact that it is a deadly, non-native pest that has killed tens of millions of ash trees in North America since its detection in 2002 in Detroit, Michigan, and Ontario, Canada.

Drought and higher temperatures likely to bring more insects

The U.S. Forest Service today released a new report, Effects of Drought on Forests and Rangelands in the United States: A Comprehensive Science Synthesis, that provides a national assessment of peer-reviewed scientific research on the impacts of drought on U.S. forests and rangelands. This report will help the Forest Service better manage forests and grasslands impacted by climate change.

“Our forests and rangelands are national treasures, and because they are threatened, we are threatened,” said Agriculture Secretary Tom Vilsack. “This report confirms what we are seeing, that every region of the country is impacted by the direct and indirect effects of drought conditions and volatile weather patterns. Sixty million Americans rely on drinking water that originates on our 193 million acres of national forest and grasslands. They support 200,000 jobs and contribute over $13 billion to local economies every year.” Continue reading

Grants from the Forest Service

The U.S. Forest Service is requesting proposals for FY2016 in the following four special program areas administered by Forest Health Protection (FHP) within State and Private Forestry:

  1. Forest Health Monitoring Program, Evaluation Monitoring (EM) – A component of the Forest Health Monitoring program designed to determine the extent, severity, and causes of undesirable changes in forest health.
  2. Special Technology Development Program (STDP) – A program to apply research results by developing cutting edge technologies and field operation methods that improve the ability of field specialists to restore and protect America’s forests.
  3. Forest Service Pesticide Impact Assessment Program (FSPIAP) – A program to evaluate the benefits and impacts of pesticide use in forest environments.
  4. Biological Control of Invasive Plants (BCIP) – A program to develop technologies that address the spread and impacts of invasive plants.

Emerald ash borer in north Louisiana

in Delta Farm Press

Efforts are underway in north Louisiana to slow the spread of an invasive species that threatens to destroy native ash trees. The trees play an important part in bottomland ecosystems and also have an economic value to the timber industry.
