Bees and other pollinators, including birds, bats, butterflies, moths, flies, wasps, beetles, and small mammals, play a critical role in our food production system. A healthy pollinator population is vital to producing marketable commodities. More than 100 U.S. grown crops rely on pollinators. The added revenue to crop production from pollinators is valued at $18 billion. Pollinators also support healthy ecosystems needed for clean air, stable soils, and a diverse wildlife. That’s why USDA’s National Institute of Food and Agriculture (NIFA) partners with the Land-Grant University System, U.S. government laboratories, and private and non-profit organizations to support research, education, and extension programs advancing pollinator health.

A cargo ship was ordered to leave the U.S. waters after U.S. Customs and Border Protection (CBP) agriculture specialists at the Port of New Orleans discovered invasive insects found in the wood used to secure its previous cargo offloaded earlier in Mexico.

The wood used to pack the aluminum shipment was found to be infested with five separate pests, two of which required action. Two of the pests discovered pose an agricultural threat to the U.S. They were positively identified by USDA entomologists as Cerambyciae and Myrmicinae.

Since 2002, forests in the southeastern U.S. have struggled against a disease called laurel wilt. In 18 years, laurel wilt has spread to 11 southeastern states and killed hundreds of millions of trees. A review article by USDA Forest Service scientist Rabiu Olatinwo reflects on the origins and spread of laurel wilt throughout the last several years. Olatinwo, a research plant pathologist at the SRS, published this research with recently retired plant pathologist Stephen Fraedrich and research entomologist Bud Mayfield in the journal Forests.

A draft integrated letter report and programmatic environmental assessment has been developed to determine the economic and environmental impacts of federal participation in state-managed watercraft inspection programs along the Upper Missouri River Basin in Montana, Wyoming, North Dakota, South Dakota and Nebraska. Public comments on the draft EA were accepted until March 2, 2021.

The existing watercraft inspection programs are managed collaboratively by the states of Montana, Wyoming, North Dakota, South Dakota and Nebraska, where watercraft transported along highways are inspected for the presence of aquatic invasive species and decontaminated when detected. If approved, federal participation in the program would be cost-shared (50 percent) with each of the states, and would employ a regional strategy to identify locations that would provide the greatest likelihood of preventing the spread of aquatic invasive species to reservoirs operated and maintained by the Corps in the Upper Missouri River Basin.

Yellowstone National Park seeks public comment on proposed measures to help stop the spread of aquatic invasive species (AIS) into park waters. The proposals include a 30-day mandatory dry time for some types of motorized boats and sailboats before entering park waters and the prohibition of watercraft previously fouled by mussels regardless of dry time.

A major tool in the fight against invasive species is the Report INvasive website, hosted by Purdue College of Agriculture and the Indiana Invasive Species Council. The website includes several ways that people can report invasive species, including a smartphone app from the Great Lakes Early Detection Network. “There are not that many specialists and experts covering the state,” Sadof said. “When there are concerned citizens reporting, however, we have many more eyes and a better chance of detecting and eradicating a harmful species early.”

The Texas Parks and Wildlife Department (TPWD) reports that invasive quagga mussels have been detected for the first time in Texas. The quagga mussel discovery was made by National Park Service (NPS) staff at the International Amistad Reservoir in the Rio Grande basin along the Texas-Mexico border near Del Rio. Quagga mussels are a close relative of the zebra mussel, which has invaded 33 Texas lakes across six river basins since it was first introduced in Texas in Lake Texoma in 2009. In addition to being the first detection of quagga mussels in Texas waters, this is also the first finding of any invasive mussel species in the Rio Grande basin.

TPWD and partners monitor for invasive mussels in Texas lakes, but anyone who finds them in lakes where they haven’t been found before should report them immediately by emailing photos and location information to AquaticInvasives@tpwd.texas.gov.

Invasive aquatic species are known to be one of the biggest drivers of biodiversity loss, and their management especially in marine environments is incredibly challenging. To tackle this issue, the GloFouling Partnerships, led by the International Maritime Organization (IMO) and in collaboration with the International Council of Marine Industry Associations (ICOMIA), World Sailing, and the International Union for Conservation of Nature (IUCN), has published a new Biofouling Management for Recreational Boating Report [PDF, 13.4 MB]. The aim of the report is to stop the spread of invasive aquatic species which can adhere to hulls and other areas of recreational craft by addressing how to manage biofouling.

Biocontrol is an important management tool that utilizes one species (a biocontrol agent) to control another (a target host) and can be an effective approach for controlling populations of invasive species across broad spatial scales. There are growing concerns that mismatches between how biocontrol agents and their hosts respond to climate change could alter the efficacy of current and future biocontrol programs.

Both scientists and regulators have had a lot to say about the growing problem of herbicide resistance and how weed management techniques need to change in response. But there have been few organized opportunities for farmers to make their voices heard and to share their experiences in managing herbicide-resistant weeds.

The European Commission has adopted a comprehensive new Biodiversity Strategy to bring nature back into our lives and a Farm to Fork Strategy for a fair, healthy and environmentally friendly food system. The two strategies are mutually reinforcing, bringing together nature, farmers, business and consumers for jointly working towards a competitively sustainable future. The new Biodiversity Strategy tackles the key drivers of biodiversity loss, such as unsustainable use of land and sea, overexploitation of natural resources, pollution, and invasive alien species. The strategy proposes to, among others, establish binding targets to restore damaged ecosystems and rivers, improve the health of EU protected habitats and species, bring back pollinators to agricultural land, reduce pollution, green our cities, enhance organic farming and other biodiversity-friendly farming practices, and improve the health of European forests. The strategy brings forward concrete steps to put Europe's biodiversity on the path to recovery by 2030, including transforming at least 30% of Europe's lands and seas into effectively managed protected areas and bringing back at least 10% of agricultural area under high-diversity landscape features.

The Aquatic Invasive Species Commission and key partners received input from and engaged in dialogue with key stakeholders, federal and state decision makers, and leading experts. Recommendations focus on modernizing marine fisheries laws, making strategic investments, and improving collaboration among federal, state, local, and tribal agencies. The purpose of this collaborative process was intended to assess the current threat from aquatic invasive species (AIS), explore gaps in public policy and funding, and offer recommendations for how AIS can be addressed more effectively at the federal, state, tribal and regional levels.

A new report has identified an international 'bug superhighway' capable of carrying a large variety of environmentally destructive overseas insects into Australia. The study, led by Monash University, rated the environmental harm being caused by 100 of the worst overseas insect species and recommends a string of actions to keep them out of Australia. The most dominant group of invasive insects by far are the hymenopteran insects – ants, bees and wasps – making them the world's most environmentally harmful invasive insect species.

"Our report found that environmentally harmful bugs, beetles, ants and moths are most likely to hitch a ride into Australia along an international bug superhighway made up of imported plants, nursery material and the timber trade," said report author Professor Melodie McGeoch from Monash University. The report identifies the international trade in cut flowers and foliage as a high-risk pathway for more than 70 of the species studied. Invasive Species Council CEO Andrew Cox said this is the first time Australian and international scientists have comprehensively analysed which invasive insects overseas are doing the most environmental harm and could therefore threaten Australia's natural environment if they breach the nation's borders.

Widespread sampling for invasive crayfish had never occurred in Kansas lakes – that is, until the Kansas Department of Wildlife and Parks (KDWP) recently funded a university project focused on the freshwater crustacean. KDWP's Aquatic Nuisance Species Program and Ecological Services section funded the project with the overarching goal of establishing sampling protocols that could then be used for long-term monitoring of both native and invasive crayfish in Kansas. During capturing efforts at McPherson State Fishing Lake – one of several small waterbodies slated to be inspected in the state – university researchers collected multiple Rusty Crayfish. Rusty Crayfish have not previously been documented in the wild in Kansas, making this official "discovery" the first of its kind.

Anglers, boaters and watersport enthusiasts are encouraged to keep their eyes open for this invasive species, which can be identified by its trademark large, black-tipped claws and rust-colored spots on its upper shell. If one is discovered, freeze it in a sealed plastic bag, note the date and location of capture, and contact KDWP's Emporia Research and Survey Office at (620) 342-0658.

The $900,000 grant will help Virginia Tech researchers see if the spotted lanternfly can help spread a fungus that kills the tree-of-heaven. The goal of the grant is to develop a native fungus as a biocontrol for the tree-of-heaven. Researchers are investigating whether the spotted lanternfly could help transmit the fungus from tree to tree, reducing the need for human intervention.

The Lionfish Challenge 2022, the seventh annual, is a summer-long tournament that rewards divers for their lionfish harvests. The tournament boasted a total of 707 registered participants, the most in the program’s history. 196 divers conducted a total of 676 trips throughout the state during the 3-month tournament and brought in a whopping 25,299 lionfish.

The widely cited “tens rule” in invasion ecology suggests that approximately 10% of established, non-native species will become invasive–or display negative impacts—when introduced to new environments. This study demonstrates that the tens rule is a poor estimate of invasion rates on a global scale. Instead, a ‘twenties rule’ is a better rule of thumb, meaning that roughly 20% of all established, non-native species eventually become invasive

The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.
