The Bureau of Land Management has released the final programmatic environmental impact statement for fuels reduction and rangeland restoration in the Great Basin. This programmatic environmental impact statement (PEIS) is intended to further efforts to conserve and restore sagebrush communities within a 223 million-acre area that includes portions of Idaho, Oregon, Washington, California, Nevada and Utah.

Sagebrush communities in the Great Basin are a vital part of Western working landscapes and are home to over 350 species of plants and wildlife. Intact sagebrush communities are disappearing within the Great Basin due to increased large and severe wildfires, the spread of invasive annual grasses, and the encroachment of pinyon-juniper. The Great Basin region is losing sagebrush communities faster than they can reestablish naturally. Fuels reduction and rangeland restoration treatments can reduce fire severity, increase sagebrush communities' resistance to invasive annual grasses and improve their ability to recover after wildfires.

DHS. Customs and Border Protection.

U.S. Customs and Border Protection (CBP) agriculture specialists have already intercepted a dozen significant and potentially destructive pests this year at various ports of entry in Florida as part of the agency's all-encompassing efforts to safeguard American agriculture.

Unknown pests pose a significant risk in agriculture due to a lack of knowledge in controlling the pests and the extent of damage they can cause to crops. U.S. Department of Agriculture (USDA) entomologists recently classified eight pests discovered by CBP agriculture specialists in Florida as first-in-the-nation interceptions and another pest as a new species.

Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

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.

The National Park Service (NPS) has finalized a long-term strategy to reduce the impacts and threats from invasive plants and to restore native plant communities and historic landscapes for 15 national park areas in D.C., Maryland, Virginia and West Virginia. The Invasive Plant Management Plan will guide park staff in standardizing and streamlining their treatment of non-native invasive plants. The plan will also help the NPS identify areas with the most urgent needs in order to address the most immediate threats to park resources. Each of the 15 area parks will develop an annual non-native invasive plant treatment strategy that is based on science, is cost effective, and poses the least amount of risk to people and park resources.

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.

White-nose syndrome (WNS) has killed more than six million bats over the past decade. WNS is caused by the fungus Pseudogymnoascus destructans (Pd). Studies show that bats eat enough insect pests to save the U.S. corn industry more than $1 billion a year in crop damage and pesticide costs, and more than $3 billion per year to all agricultural production including forests.
 

To help fund the research needed to combat this deadly disease, the U.S. Fish and Wildlife Service announced $2.5 million in grants for research of high priority questions about WNS that will improve our ability to manage the disease and conserve affected bats.

Laurel wilt has devastated plants in the Lauraceae family – redbay, sassafras, pondberry, avocado, and others – since it was first detected in the southeastern U.S. around 2002. There is no widespread, effective treatment for laurel wilt. Genetics research is focused on learning more about the pathogen's genetic structure in order to improve detection methods and screening for possible resistance in Lauraceae host species. "We have developed genetic markers to describe the population of the pathogen in the U.S.," says USDA Forest Service plant pathologist Tyler Dreaden. "Knowing which genotypes to use contributes to a quicker, more cost-effective resistance screening process." Dreaden led a new study to shed light on the genetic structure of the pathogen and its reproductive strategy. The research team included Marc Hughes at the University of Hawaii at Manoa, Randy Ploetz and Jason Smith at the University of Florida, and Adam Black, horticulture director of the Peckerwood Garden Conservation Foundation in Texas. Their findings were published in Forests.

The Administration announced a new interagency conservation agreement to protect western water supplies, power generation, outdoor recreation and aquatic ecosystems by strengthening efforts to combat invasive mussels.

A Memorandum of Understanding (MOU) among the U.S. Army Corps of Engineers, U.S. Department of Agriculture Forest Service, and six Department of the Interior bureaus focuses on boosting federal coordination, communication and collaboration to enhance the capacity of federal, state and tribal agencies to rapidly respond to discoveries of invasive mussels in western states.

DOD. USACE. Buffalo District.

The U.S. Army Corps of Engineers Buffalo District is on a mission to fight hydrilla, an aggressive plant species that has wreaked havoc from Asia to every continent except Antarctica. "Hydrilla completely chokes out our waterways and impacts all the things we enjoy,” said Michael Greer, USACE Buffalo District project manager." It affects water quality, the economy, businesses, hydropower and flood reduction - ultimately our health and our wallets." Buffalo District’s main projects to eradicate hydrilla are at the Erie Canal and Tonawanda Creek, Tonawanda, NY, as well as on Cayuga Lake near Aurora, NY and Ithaca, NY. The District provides assistance on Pymatuning Lake which borders Pennsylvania and Ohio, and at Raystown Lake in south central Pennsylvania. Buffalo District is also lending expertise to a project on the Connecticut River. Funding for the project is available through the Corps of Engineers Aquatic Plant Control Research Program and Great Lakes Restoration Initiative.

Early in October 2016, the U.S. Department of Agriculture (USDA) was faced once again with New World screwworm, which had been eradicated from the United States more than three decades ago. Infestation of this flesh-eating parasite was confirmed in deer from the National Key Deer Refuge in the Florida Keys.

 

USDA’s Animal and Plant Health Inspection Service (APHIS) immediately began releasing sterile male flies in Florida’s affected areas as part of an aggressive eradication campaign. By March 2017, the screwworm had been successfully eradicated from Florida.
