The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental effects of establishing an integrated management strategy to control cogongrass in Alabama, Georgia, Mississippi, and South Carolina. The draft environmental assessment is now available for comment. Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. Because of cogongrass' impact on agriculture and forest industries, Congress has given APHIS funding to partner with Alabama, Georgia, Mississippi, and South Carolina to control the spread of this weed. APHIS is proposing is an integrated management strategy that uses preventive, cultural, mechanical, biological, and chemical methods to control cogongrass in key areas of its distribution. APHIS invites the public to review and comment on this environmental assessment by April 1, 2020.

Cattle grazing on a nearly half mile wide targeted strip of cheatgrass near Beowawe, Nevada, created a firebreak that helped limit a rangeland fire to just 54 acres this past August compared to rangeland fires that more commonly race across thousands of acres of the Great Basin. This "targeted grazing" firebreak and eight others are part of an evaluation project being managed by the Agricultural Research Service (ARS), partnering with other federal, state and local agencies and local cattle ranchers in Idaho, Nevada and Oregon. These demonstration sites are being studied so the concept's efficacy and environmental impacts can be uniformly evaluated and compared.
Cheatgrass, also known as downy brome, is an invasive annual that dominates more than 100 million acres of the Great Basin in the western U.S. Germinating each winter, cheatgrass grows furiously in spring and dies in early summer, leaving the range carpeted in golden dry tinder. The Great Basin now has the nation's highest wildfire risk, and rangeland fires are outpacing forest fires when it comes to acreage destroyed.

U.S. Department of the Interior Assistant Secretary, Insular and International Affairs, Douglas W. Domenech announced $942,206 in fiscal year (FY) 2020 Coral Reef and Natural Resources Initiative grants to eradicate and control the spread of invasive species in the U.S. territories of Guam and the Commonwealth of the Northern Mariana Islands (CNMI), as well as in the Republic of Palau, and Yap, in the Federated States of Micronesia (FSM). Funding will be used to introduce biological control of coconut rhinoceros beetles, control and eradicate feral cats and monitor lizards, and destroy wild vines, all of which are disruptive to ecological systems and impacting communities and livelihoods in the islands.

Forest Service scientists have published a guide synthesizing best practices for controlling these tiny bugs. It promotes a strategy of combining insecticide use with adelgid-eating insects.

Watercraft Inspection and Decontamination Programs - Many Western states instituted watercraft inspection and decontamination programs after the discovery of invasive mussels in Lake Mead in 2007. This section provides resources on mandated watercraft inspection and decontamination programs, as well as some non-mandated but state-funded watercraft inspection efforts.
Aquatic Invasive Species Decals - Some U.S. states require that boaters purchase an aquatic invasive species decal (sometimes called a stamp, sticker, or permit) before operating watercraft in that state. Many of these regulations were instituted as a response to the spread of zebra mussels and quagga mussels into the Western U.S. Fees from the purchase of these decals are typically used to fund local aquatic invasive species outreach and prevention activities.

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch. The research, appearing online in the journal Biological Invasions, is based on a new model that simulates interactions between the bigheaded carps and a range of fish species, including walleye, yellow perch, and groups lower on the food web over a time period of 50 years. Over 180 non-indigenous aquatic species have already become established in the Great Lakes, with a handful of these producing substantial negative impacts. While bigheaded carps are established in watersheds near the Great Lakes, they have not yet become established in the Great Lakes.
