The Arkansas Department of Agriculture is pleased to announce the release of the newly created Arkansas Feral Hog Handbook, a guide to resources available in Arkansas to assist with feral hog control and eradication. The handbook includes contact information, websites, and brief explanations of the resources offered by state and federal agencies and other entities. "The Arkansas Feral Hog Handbook was made possible through a grant funded by the United States Department of Agriculture's Natural Resources Conservation Service. We appreciate their partnership and the information provided by other Feral Hog Eradication Task Force members to make the handbook a comprehensive educational resource for Arkansans," said Arkansas Secretary of Agriculture Wes Ward.

The handbooks are being distributed to the public at locations throughout the state with assistance from partner organizations, including the Arkansas Association of Conservation Districts, University of Arkansas Cooperative Extension Service, Arkansas Game and Fish, and Arkansas Farm Bureau. Copies of the handbook can be requested at lori.scott-nakai@arkansas.gov. An online version of the Arkansas Feral Hog Handbook (2020) [PDF, 4.48 MB] is also available.

The U.S. Geological Survey has released a comprehensive synthesis of Burmese python science, showcasing results from decades of USGS-funded research on python biology and potential control tools. The giant constrictor now represents one of the most challenging invasive species management issues worldwide.

On June 1, a new regulation was published in the Delaware Register of Regulations (Volume 26, Issue 12) listing potbellied pigs and feral swine of any kind as invasive. The Delaware Department of Agriculture (DDA) is providing a 30-day grace period for potbellied pig owners to apply for an Invasive Animal Permit. Owners have until August 12 to submit an application and comply with 3 DE Admin. Code 906 Possession, Sale, or Exhibition of Non-Native and Invasive Animal Species.

Whether called wild pigs, feral hogs, or wild boars, these opportunistic and invasive omnivores live in groups called sounders. Removing whole sounders is the most effective management method, but requires follow-up trapping and hunting due to their incredible reproductive potential.

Coastal marshes that have been invaded by feral hogs recover from disturbances up to three times slower than non-invaded marshes and are far less resilient to sea-level rise, extreme drought and other impacts of climate change, a new study led by scientists at Duke University and the University of Massachusetts Boston (UMB) finds. "Under normal circumstances, marshes can handle and recover from drought or sea level rise, given time, but there is no safety net in place for hog invasions," said Brian Silliman, Rachel Carson Distinguished Professor of Marine Conservation Biology at Duke, who co-authored the study.

All known feral swine have been eliminated from Colorado thanks to a near 15-year state and federal partnership comprised of the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS), the USDA Forest Service (FS), Colorado Parks and Wildlife (CPW) and the Colorado Department of Agriculture (CDA). The partnership formed in the early 2000s as a task force to manage invasive feral swine, which root up crops and pastures causing billions in damage nationwide each year. Feral swine also spread disease to livestock, wildlife and humans. Ground-nesting birds and other wildlife are easy prey for feral swine. And the swine put native wildlife at risk by competing for resources and destroying habitats and ecosystems. 

You can help keep Colorado free of feral swine:

• Spread the word that in Colorado it’s illegal to possess, transport or release feral swine, wild swine species or hybrids.
• Report sightings of feral swine or transportation activities to USDA Wildlife Services at 1-866-4-USDA-WS (1-866-487-3297) or Colorado Parks and Wildlife at 303-297-1192.
• Get more information at the National Feral Swine Damage Management Program.

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.

South Carolina has documented its first black and white tegu lizard, a species popular in the pet trade, in Lexington after a SCDNR social media post in May informed the public about the non-native lizard already established in both Georgia and Florida, likely as a result of release or escape. SCDNR staff have been monitoring the situation closely and have received multiple reports since May from Lexington and Aiken counties. No previous reports could be confirmed.

SCDNR asks people to report any sightings of black and white tegus in the wild to Andrew Grosse, grossea@dnr.sc.gov. If possible, please submit a photo, location, and time and date the individual was seen.

At its February 2021 meeting, the Florida Fish and Wildlife Conservation Commission (FWC) approved staff recommendations to create new rules to address the importation, breeding and possession of high-risk invasive reptiles. The approved rule changes to Chapter 68-5, F.A.C. specifically address Burmese pythons, Argentine black and white tegus, green iguanas and 13 other high-risk nonnative snakes and lizards that pose a threat to Florida’s ecology, economy, and human health and safety.

On Jan 10, 2020, the Florida Python Challenge™ 2020 Python Bowl officially kicked off in South Florida with more than 550 people registered for the competition to remove as many pythons from the wild as possible. Native to Southeast Asia, pythons pose a significant threat to Florida’s native wildlife. Under the direction of Florida Governor Ron DeSantis, the Florida Fish and Wildlife Conservation Commission (FWC) and the South Florida Water Management District (SFWMD) have teamed up with the Miami Super Bowl Host Committee and other partners to support the Committee’s Ocean to Everglades (O2E) initiative, which features the Python Bowl. It’s not too late! People interested in taking part in the Florida Python Challenge™ 2020 Python Bowl can still register at FLPythonChallenge.org. 

Researchers have published a first- of-its-kind study that shows that near-infrared (NIR) spectrum cameras can help python hunters more effectively track down these invasive snakes, especially at night.

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.

The U.S. Department of the Interior's Office of Insular Affairs (OIA) has announced $4,095,922 million in Brown Tree Snake Control program fiscal year (FY) 2021 funding as administered through the Technical Assistance Program. An additional amount of $1,791,421 from Coral Reef and Natural Resources FY 2021 funds was also announced earlier this year for the purpose of controlling and mitigating other invasive species in the Insular Areas besides the brown tree snake. "Islands are particularly vulnerable to invasive species that disrupt natural, long-standing biological processes and threaten our unique, island eco-systems," said Deputy Assistant Secretary Keone Nakoa. "Each year, OIA provides significant funds to critical efforts seeking to help restore balance."

The Brown Tree Snake Control program FY 2021 funding was divided among several governments and federal partners to include Guam, the Commonwealth of the Northern Mariana Islands (CNMI), Hawai'i, U.S. Department of Agriculture (USDA), and the Department of the Interior.

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.

Scientists tallying the economic damage wrought by invasive pests across the world found two species are responsible for more harm than any other.

The American bullfrog and brown tree snake have collectively caused $16.3bn in global damage since 1986. In addition to ecological harm, the invasive pair have ruined farm crops and triggered costly power outages.

The Montana and Washington invasive species councils have joined forces to stop wild pigs from crossing borders. The two councils issued a report with recommendations and best management practices aimed at helping federal, state, provincial and local landowners manage wild pigs in the western United States and Canada. "Wild pig populations are expanding in the western provinces of Canada and in the United States." said Stephanie Criswell, coordinator of the Montana Invasive Species Council. "We are at a unique point in time where we can work together to prevent Canadian wild pigs from spreading across borders into unaffected states like Montana."

In early 2020, the two invasive species councils convened a working group of more than 40 federal, state and Canadian feral swine experts to discuss challenges and opportunities to prevent feral swine along interstate and international borders. Finalized this month, the report includes 22 recommendations that address five strategic areas of feral swine management. Recommendations include standardizing communications to the public, expanding monitoring networks by partnering with non-traditional organizations such as hunting groups, and formalizing notification protocols for reports that will be shared between state and provincial authorities along the international border. The complete report can be found at misc.mt.gov.

Invasive tegu lizards from South America are currently established in four locations in Florida and negatively impact native, ground-nesting animals in the Greater Everglades Ecosystem. Two newly published research studies from the U.S. Geological Survey show that, depending on their size and body condition, tegu lizards could survive in cooler, northern climates.

The Argentine black and white tegu is a large lizard from South America currently inhabiting the Florida counties of Charlotte, Hillsborough, Miami Dade and St. Lucie. Tegus are introduced to the U.S. through the pet trade and then likely released from captivity into the environment. "Several lines of evidence from recent USGS research studies published from 2018 to 2021 now provide clear indication for managers that the entire southeast portion of the United States is at risk of tegu establishment if lizard releases continue unabated," said Amy Yackel Adams, a USGS research ecologist.
