Over the past decade, USDA Forest Service researchers have been working with university cooperators to find some way to slow down or stop the relentless spread of cogongrass.

Much as the Asian long-horned beetle attacked maple and elm trees on the East Coast, the coconut rhinoceros beetle could devastate Hawaii's palm trees and move on to bananas, papayas, sugar cane and other crops afterward. Adult beetles burrow into the crowns of palm trees to feed on their sap, damaging developing leaves...

For some animals, there’s no such thing as a dog-eat-dog world. They rule. Animals from around the world that stow away in airplanes, ships and the luggage of some smuggler become almost bulletproof when they make their way into the American wilderness as invasive species.

A Michigan State University scientist has developed a smart phone application to help keep track of invasive species. The free app is part of the Midwest Invasive Species Information Network developed by bio-geographer Amos Ziegler. It enables people who think they’ve spotted an invasive critter or plant to photograph it...
