The USGS Ecosystems Mission Area provides science to understand wildlife diseases, including avian influenza (AI). Avian influenza viruses occur naturally in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds but they can be highly pathogenic and cause illness and death in poultry and wildlife.

Understanding how wild birds facilitate the maintenance, reassortment, and dispersal of influenza A viruses (IAV) is key to forecasting global disease spread. The current highly pathogenic avian influenza outbreak in North America highlights the question of how viruses are transported between continents. Recent NWHC research sheds light on this question and the potential role Iceland may play.

Boxwood blight is a fungal disease that can cause the leaves of boxwood plants to fall off prematurely. ARS scientists in Fort Dietrick, MD, are studying how boxwood blight evolves and are working closely with the floriculture and nursey industry to develop methods for testing, controlling, and mitigating the disease.

A unique program run by the Agricultural Research Service in Fort Pierce, FL, uses specially trained dogs to detect citrus greening in orchards. The canine-detection method has an accuracy rate of 99 percent.

USDA Forest Service researchers are monitoring the effects of white-nose syndrome, a fungal disease from Eurasia that has decimated cave-hibernating bats across the U.S. since its arrival in 2006. "The fungus that causes white-nose syndrome grows on bats in the wintertime. It causes them to wake up during their hibernation and burn their fat reserves," says Phillip Jordan, wildlife biologist. Jordan is among the experts featured in a new video, Bats on the Brink. Forestry technician Virginia McDaniel created and produced the video.

The Maine Department of Agriculture, Conservation and Forestry has announced an addition to the state's invasive species list. Beech leaf disease, leading to the decline and mortality of beech trees from Ohio to southern New England, has arrived in Maine's forests. The disease was confirmed in leaf samples from a forest in Lincolnville (Waldo County) by Dr. Robert Marra of the Connecticut Agricultural Experiment Station. The Maine Forest Service is asking the public's help in identifying additional areas impacted by beech leaf disease. If you suspect you have found affected leaves submit photos using the MFS tree ailment form, email foresthealth@maine.gov, or call (207) 287-2431. Photos should include a clear shot of the underside of an affected leaf or leaves. However, please report concerns even if photos cannot be provided.
