With support from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA), the National Plant Diagnostic Network has grown into an internationally respected consortium of plant diagnostic laboratories dedicated to enhancing agricultural security by protecting health and productivity of plants in agricultural and natural ecosystems.
Dr. Ray Hammerschmidt, President of the National Plant Diagnostic Network, discusses this partnership and the benefits all Americans receive in the following guest post:
Superheroes really do work among us. But, instead of capes and cowls and ice palaces and caves, they are often found in a lab at a public university or state agriculture department, wearing lab coats and working over a microscope.
These men and women work daily to protect our communities and crops from dangerous pests and pathogens. They are plant pathologists, entomologists, nematologists, weed scientists, and other plant scientists who work diligently to mitigate the impact of endemic, emerging, and exotic pathogens and pests that attack agricultural, forest, and landscape plants in the United States.

This month USDA highlights some of the important partners that work with us to care for our land, air, water, and wildlife. The National Invasive Species Council is one such group.
When you hear the word “invasive,” most people automatically think of bugs and weeds. Unfortunately, invasives (or non-native pests) can also include wildlife, such as birds, reptiles, amphibians, and mammals. Read more »
Forest Service scientists use a greenhouse in Washington State to grow bluebunch wheatgrass as part of their current reciprocal transplant project. It is one of the largest and most intensive projects of its kind ever attempted.
Wildfires in sagebrush and other range ecosystems are increasing in frequency and severity, often in relation to drought conditions and intrusive species like cheatgrass, a non-native, highly flammable invasive species that establishes itself as a monoculture and crowds out native grasses and forbs.
“What’s preferable to a monoculture is a diverse plant community that includes native grasses, forbs and shrubs,” said Francis Kilkenny, leader for the Great Basin Native Plant Project, a joint effort of the U.S. Forest Service and the Department of Interior’s Bureau of Land Management, or BLM.

USDA Wildlife Services research has led to the development of an aerial bait to control invasive brown tree snakes on Guam. The effort was awarded the Department of Defense’s 2015 Project of the Year Award for Resource Conservation and Climate Change.
This month USDA highlights some of the important partnerships that work with us to care for our land, air and water. The work stretches into areas and takes USDA employees to places you wouldn’t suspect.
For example, the damage wreaked by invasive brown tree snakes on Guam is hard to imagine.
Infestations of the snake have led to the loss of all but two of the twelve native forest birds on the island, millions of dollars in damages to the island’s electrical power grid, and physical injuries to residents from snake bites. Read more »
The Asian Longhorned Beetle has killed more than 100,000 trees since it was accidentally introduced to this country about 20 years ago.
USDA APHIS is deeply involved with mitigating invasive pest issues, along with State and local governments. Invasive pests cost the U.S. an estimated $120 billion each year in damages to our environment, agriculture, and native species. The five invasive species described here are a few of the damaging invasive pests of concern to the Animal and Plant Health Inspection Service. You can help detect these pests and take actions to reduce their spread. Read more »
U.S. Department of Agriculture (USDA), Animal Plant Health Inspection Service (APHIS), Wildlife Services program specialist Mario Eusi and his dog Cain at their graduation ceremony certifying them for Nutria Detection at the Blackwater National, Wildlife Refuge, MD.
Mya, Hektor and Cain are seated on the floor, next to their handlers and partners, waiting for their names to be called. It’s a big day for the three shelter dogs and their handlers. You may be surprised to learn that many of the dogs trained at APHIS’ National Detector Dog Training Center are rescues. Mya and Cain are from Maryland’s Montgomery County Animal Services & Adoption Center and Hektor is from the Fulton County Animal Shelter in Atlanta. They are all officially graduating from the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service’s (APHIS) detector dog training program, and will join two other rescue dogs trained last year and currently part of other detector dog teams as part of the effort to find and eliminate the last of the nutria from the Delmarva Peninsula.
Nutria are invasive, semi-aquatic rodents that live in marshes throughout the country. They weigh between 12 and 20 pounds and were brought to Maryland’s Lower Eastern Shore from South America for their fur in 1943. However, their dark brown pelts were not profitable, and they were either released or escaped from fur farms. With no natural predators, the nutria population at Maryland’s Blackwater National Wildlife Refuge exploded. Read more »
