Fire-friendly grasses have invaded new habitats around the world. Five species (cheatgrass, cogon grass, gamba grass, molasses grass, and buffelgrass) are considered among the most problematic grasses, threatening to transform entire ecosystems.

Invasive non-native insects have been called the "wildfires of the East," given the damage they cause to trees. One pest, the emerald ash borer, has killed hundreds of millions of rural and urban ash trees. To help arborists and city planners track and treat potential outbreaks, U.S. Forest Service scientists seek efficient monitoring techniques.

Argentine black and white tegus have spread and established populations in and around Florida at a rapid and growing rate demonstrating critical implications for native wildlife, numerous natural areas, and even restoration efforts for Everglades National Park. UF scientists at the Institute of Food and Agricultural Sciences (UF/IFAS) and partnering agencies have co-authored the “Growth and Spread of the Argentine Black and White Tegu Population in Florida” illustrating the depth and breadth of the tegu problem. The comprehensive fact sheet details the invasion of the species, the tegu population’s increase, impacts for wildlife and natural areas at stake, interagency goals and efforts to reduce the threat, and the implications of species expansion.

Fire ants cause significant harm not only to humans, but to the food we grow? Imported fire ants have invaded about 350 million acres in the U.S., and they cause approximately $8 billion in economic damages per year.

Learn more about what’s happening with this invasive species that has spread throughout the southern U.S., and what ARS is doing about it, as the Office of Communications launches a week-long fire ant campaign (June 22-28, 2024). ARS will feature videos, articles, and interviews with our scientists who are leading the fight against these tiny invaders.

ARS scientists are using a unique receptor interference technology that they have developed to target fire ants. The technology is environmentally friendly and can also be directed at other existing or emerging invasive pests to provide timely, cost-efficient pest control.

This database contains literature reviews of botanical characteristics, life cycle, habitat, succession, distribution, impacts, fire ecology, and fire effects for 1000 plant and animal species, including 67 non-native invasive species. Future plans include updating many of these "species summaries" and adding 30-40 more summaries of non-native invasives over the next 1.5 years.
