Humans adores trees. But humans also migrate and trade, habits that led to the accidental introduction of insects and diseases that harm trees and alter the landscape. Examples are easy to find and may be outside your front door: American elms that once dotted streets across America succumbed to Dutch elm disease. Now all colors of ash species – black, green, white, pumpkin, and blue – are threatened by emerald ash borer. The already uncommon butternut tree, also known as white walnut, faces the possibility of extinction from a mysterious attacker. Many invasive insects and fungi come from regions where native trees have evolved to resist their attacks. When these species enter the United States, they find trees that lack this resistance. There's no immediate end to this dismal pipeline, but there is hope on the horizon.

The annual Lionfish Challenge is an incentive program that rewards harvesters for their lionfish removals. With a tiered system, everybody can be a winner. The participant who harvests the most lionfish will be crowned the Lionfish King/Queen. The Challenge is open now and will run through November 1. You can register for the 2020 Lionfish Challenge and find more information at FWCReefRangers.com/Lionfish-Challenge. Questions regarding the challenge can be sent to Lionfish@MyFWC.com.

Early detection is critical to the eradication and management of invasive species, and curious members of the public play a key role by sharing observations on platforms such as iNaturalist. Integrating these sightings from a bug-curious public into ongoing biosecurity surveillance is an increasingly valuable approach for invasive species management.

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. 

The Florida Fish and Wildlife Conservation Commission (FWC) and the Southwest Florida Cooperative Invasive Species Management Area (CISMA) invite the public to participate in the 2022 Invasive Fish Roundup event, targeting freshwater invasive fish species. This event (April 28-May 1, 2022), with the weigh-in occurring on May 1 from12-3 pm at Bass Pro Shops, 10040 Gulf Center Drive, Fort Myers, Florida 33913; the weigh-in is open to the public.

The roundup is a 3-day event that is open to teams of one to four anglers, fishing from shore or boat in the Southwest Florida CISMA area (Collier, Lee, Charlotte, Hendry and Glades counties) with prizes awarded to the top team in various categories and free giveaway prizes for all participants. The goal of this event is to encourage the public to target invasive species while fishing and to promote awareness of the potential negative impacts of releasing invasive species into Florida’s waterways. This is also an opportunity for Southwest Florida CISMA and the FWC to gather information about invasive fish distribution and abundance, both of which could help with future management of invasive fish species.

Late spring heralds the start of open water fishing season. For the casual angler, it's easy to take for granted the abundance of fish this time of year. However, many species, especially native fish, can use their help. "There are so many issues affecting the health of fish populations – barriers caused by dams and roads that cross streams fragment fish habitat. Water is diverted out of streams for other uses," said Tina Hopkins, the regional fisheries program manager for the Forest Service’s Intermountain Region. "But perhaps the biggest threat across the country is aquatic invasive species."

Fisheries biologists from around the country have recommended a few ways that anglers, boaters and recreators can do their part to ensure healthy fish stocks for seasons to come. Here is their advice to recreators, in their words:

• "Consult your lawbook, know the rules, and please don’t move fish around."
• "It is extremely important that anglers clean their boats, trailers, waters, and gear when they are done fishing for the day."
• "Every drainage is going to be different, so anglers should be informed about where they are fishing."

The United States Department of Agriculture (USDA) proclaims April 2024 as Invasive Plant Pest and Disease Awareness Month. During this month, we are encouraging everyone—whether you’re a gardener or a camper, a bug enthusiast or a student, a traveler, or an online shopper—to learn about the danger of invasive plant pests and what you can do to help. During the month, we are sharing information on curbing the spread of these pests to foster a healthier environment and protect our food supply.

The Wyoming Game and Fish Department is offering training for members of the public to become a certified Wyoming aquatic invasive species inspector. The free, day-long sessions are offered throughout the spring in statewide locations and are open to anyone interested in preventing the spread of AIS through watercraft inspection. The training includes information on basic biology of invasive species, the impacts of AIS, transport vectors and distribution of AIS. It includes classroom instruction, a question-and-answer session and a hands-on watercraft inspection exercise. Those who complete the class will be certified to inspect watercraft.

Learn simple steps you can take to prevent the spread of invasive species when you recreate outdoors.

We need your help to monitor for and report northern giant hornet sightings. By participating in a northern giant hornet citizen scientist project, you are helping protect your community from northern giant hornets.

Since the first report of a northern giant hornet in Washington in 2019 (known as the Asian giant hornet or the “murder hornet” back then), the Washington State Department of Agriculture’s (WSDA) Pest Program has been working to eradicate northern giant hornets. The best time to participate is from July through November. You are most likely to see or catch a northern giant hornet during this timeframe because colonies are established, and workers are out hunting.

People ship and receive packages using express courier companies—like FedEx, UPS, DHL, and others—all the time. But when the package includes an agricultural item, things could get dangerous for U.S agriculture and natural resources.

“You should know what could be hitchhiking in or on those items—invasive plant and animal diseases and pests,” said Dr. Mark Davidson, Deputy Administrator of USDA’s Plant Protection and Quarantine. “Once these threats enter our country, they could harm our crops, livestock, and ecosystems. Left unchecked, they could devastate entire agricultural industries, eliminating jobs, threatening our food supply, and costing billions of dollars in losses and response costs.”

The annual PlayCleanGo Awareness Week (June 1-8, 2024) will be held across North America. The goal of the campaign is to show outdoor enthusiasts how they can stop invasive plants and pests from spreading — while enjoying the great outdoors.

PlayCleanGo is an education and outreach campaign for outdoor recreationalists in North America. The goal is to encourage outdoor recreation while protecting valuable natural resources. The objective is to slow or stop the spread of terrestrial invasive species (those that occur on land) through changes in public behavior. See how you can take action and stop invasive species in your tracks.

As a resource professional (construction, agriculture, horticulture/growers, road crews) you see firsthand what invasive species can do to the landscape, so it is important that you remain vigilant in your own prevention actions. You and the work that you do as an outdoor professional play a crucial role to the success of biodiversity and reducing the spread of invasive species. Learn how you can prevent the spread of invasive species.

Discover Life in America, the nonprofit research partner of Great Smoky Mountains National Park, is inviting the public to participate in its latest project, Smokies Most Wanted, an initiative that allows visitors to help conserve park species by recording sightings of animals, plants and other organisms from their smartphones. Powered by the nature app iNaturalist, Smokies Most Wanted encourages park visitors to document any organism they encounter while hiking, camping, or otherwise enjoying the park — from birds to wildflowers, insects to lichens. DLiA then uses the data collected through iNaturalist for a variety of functions, like recording new park species or detecting invasive ones, learning about under-studied or rare species, and mapping species across the park.

Washington state agencies are asking people to clean their gear, pets and clothing this spring to prevent invasive plants from establishing here.

Washington state agencies are asking for your help to check your trees for signs and symptoms of invasive insects. Damaging invasive insect species, such as spotted lanternfly, longhorned beetles, and emerald ash borer, are emerging in their adult form. ate summer is often the peak time for these invasive insects to emerge from trees in their adult stage. If you see or suspect you see an invasive insect, report a sighting.

If you are moving this year from a location within the gypsy moth quarantine area to a location outside the quarantine area, please inspect outdoor household items for pests. This is a federal requirement for homeowners moving from gypsy moth quarantine areas.

By complying with the law, you may also save a forest. Gypsy moths are destructive, invasive pests! European gypsy moth larvae feed on over 300 plant species including oak, aspen and elm. Gypsy moths have defoliated more than 83 million acres in the United States since 1970. About 70% of susceptible forests have never been infested and are at risk.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is asking the public to look for and report the Asian longhorned beetle (ALB). APHIS declares every August Tree Check Month and is asking you to look for this destructive, invasive beetle by checking trees on your property and in your community for damage. Left unchecked, the ALB can cause infested trees to die. August is an ideal time of year to look for the beetle and the damage it causes.
