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 the release of $3,442,389 in fiscal year (FY) 2020 grant funding to suppress and control the brown tree snake (BTS), Boiga irregularis, primarily on Guam. Funds also support prevention, detection, and rapid response efforts in the Commonwealth of the Northern Mariana Islands (CNMI) and Hawaii, in addition to research and development on how to improve suppression methods and potentially eradicate the snake on Guam. The Office of Insular Affairs (OIA) Brown Tree Snake Control program FY 2020 funds are divided among several federal, state, and territorial agencies that collaborate in support of the three pillars of BTS suppression: $1,229,296 is used for control in rapid response and research activities, $1,724,210 is used for interdiction, and $488,883 is used for prevention through coordination and outreach.

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.

For the first time, an invasive brown treesnake population has been found on Cocos Island, an 83.1 acre atoll located 1.5 miles off the southwest coast of Guam. The brown treesnake was a major contributor to the loss of nine of 11 native forest birds and significant population declines of several native lizards, bats and other bird species on Guam. They now pose a threat to the wildlife of Cocos Island. Guam Department of Agriculture Division of Aquatic and Wildlife Resources is working with partners to better understand how many brown treesnakes are on the island and the best way to remove them.

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.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) in New York, Massachusetts, and Ohio in 2020. "Just last year we declared eradication of ALB from Brooklyn and Queens in New York City, ending the city's 23-year-long battle with the beetle," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "This year, we've mapped out a sound strategy that will further our efforts to eliminate this pest from the remaining areas of this country where it still has a foothold."

Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication. In 2020, the ALB program will focus on inspecting trees in quarantined areas in New York, Massachusetts, and Ohio, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. In addition, program officials will monitor for the beetle’s presence inside and around each area, respond to service calls, conduct training sessions for compliance agreement holders, and perform outreach.

The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) is announcing that effective today, we are transitioning our virulent Newcastle disease (vND) efforts in southern California from a response focus to implementing a prevention plan aimed at keeping vND from recurring in the region. Even with extensive testing taking place, APHIS has not confirmed any new vND cases since February 1, 2020. As a result, the California Department of Food and Agriculture (CDFA) is removing its vND quarantine.

USDA's Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a commercial chicken flock in Riverside County, California. This finding is part of an outbreak in southern California that began in May 2018 in backyard exhibition birds. This is the first case in commercial poultry since 2003.

Virulent Newcastle disease is not a food safety concern.  No human cases of Newcastle disease have ever occurred from eating poultry products.

On October 10, 2019, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) in coordination with the New York State Department of Agriculture and Markets, New York State Department of Environmental Conservation, and New York City Department of Parks and Recreation announced that they have eliminated the Asian longhorned beetle (ALB) from the New York City boroughs of Brooklyn and Queens. "I am proud to say that we have eradicated Asian longhorned beetle from Brooklyn and Queens," said Greg Ibach, USDA's Under Secretary for Marketing and Regulatory Programs. "This officially marks the end of our 23-year long battle with this pest in New York City."

Secretary Perdue is making available an additional $45 million to the Animal and Plant Health Inspection Service (APHIS) and its partners to address the ongoing virulent Newcastle disease (vND) outbreak in southern California. This funding will allow APHIS and the California Department of Food and Agriculture (CDFA) to strengthen their joint efforts to stop the spread of this disease and prevent it from affecting additional commercial flocks. vND has been confirmed in more than 435 backyard flocks since May 2018. It was also confirmed in four commercial flocks in December 2018 and January 2019.

On May 14, Director Reilly signed a Memorandum of Agreement with the Department of the Navy and the U.S. Fish and Wildlife Service. The MOA provides for continuity of operations for the USFWS and the USGS with construction of new office and lab facilities on the Guam National Wildlife Refuge in conjunction with DOD’s construction of a Marine Corps firing range. "The USGS has a long history of collaborating with the Department of Defense in support of U.S. facilities and force readiness in the INDOPACOM Area of Responsibility. One of our signature efforts ongoing today is a collaboration with DOD, the U.S. Fish and Wildlife Service, and the local government in minimizing the impacts of the invasive Brown Treesnakes (BTS) and improving BTS controls on military lands on Guam," said Jim Reilly, director of the USGS.
