Spread of the invasive emerald ash borer in urban forests

Negron, J., & Liebhold, A. M. (2025, December 16). Spread of the invasive emerald ash borer in urban forests. USDA Forest Service. https://research.fs.usda.gov/rmrs/articles/spread-invasive-emerald-ash-borer-urban-forests 

The emerald ash borer is an invasive species that attacks and kills ash trees. It was accidentally introduced into the United States from Asia and first discovered in Michigan in 2002. Since then, it has spread quickly across the eastern United States, killing most ash trees in areas it has invaded. In Colorado, the insect was found in a boulder in 2013, but later it was found along the Front Range. Scientists found that the emerald ash borer spreads faster in cities where ash trees are more common than in natural forests, making it harder for the insect to move. Insecticide treatments and Colorado’s drier climate also help slow the insect population growth.

This article shows how invasive species can cause serious damage, but also how local conditions can reduce their impacts. I think the slower the spread of the emerald ash borer in Colorado, the better, because it gives communities more time to prevent this problem and protect their trees. Ash trees provide shade, lower summer temperatures, and help reduce energy costs in cities. Losing them would be harmful to communities and also expensive. This article shows the importance of early management and planning when dealing with an invasive species. If communities act early and use scientific research, they can reduce the damage and protect the environment.

We are no match for the invasive lionfish, the feral hog of the sea

Alvarez, J. (2025, November 10). We are no match for the invasive lionfish, the feral hog of the sea. Texas Monthly. https://www.texasmonthly.com/travel/invasive-lionfish-gulf-spearfishing/ 

This article explains how lionfish, an invasive species from India and East Asia, are causing serious damage to the Gulf of Mexico’s underwater ecosystems. These Lionfish likely entered the U.S. through aquarium releases and now have spread rapidly because they have no natural predators in the Gulf. They eat almost any fish that they can get, mostly young fish. This, in turn, has led to major declines in native species and has harmed many coral reefs. Scientists have reported that a single lionfish can reduce native fish populations by up to 79%. Because Lionfish reproduce extremely quickly, removing them is impossible. Currently, the only way to control their population is to hunt them one by one.

This article shows just how dangerous invasive species can be, even when they appear harmless. I think it’s also alarming that this was most likely a human-caused problem. The damage these Lionfish cause not only affects marine life but also the fishing industry and the coral reefs that many communities depend on. The fact that scientists have to rely on divers to kill these lionfish shows just how serious an invasive species can be once established. This also underscores the importance of preventing an invasive species before it becomes detrimental.

 

Florida vs. the Burmese python: How an invasive giant is changing the Sunshine State

Hoskins, L. (2025, October 14). Florida vs. the Burmese python: How an invasive giant is changing the Sunshine State. Florida Museum UF. https://www.floridamuseum.ufl.edu/earth-systems/blog/florida-vs-the-burmese-python-how-an-invasive-giant-is-changing-the-sunshine-state/ 

This article explains how the Burmese python, which was an invasive species originally from Southeast Asia, has changed Florida’s ecosystem. It was introduced mainly through the exotic pet trade, the python has now slowly established itself throughout South Florida. As of large and highly effective predator, it has caused a massive decline in most Native wildlife, which are crucial for the ecosystem. Scientists report that some mammal populations have declined by more than 90 percent in areas where pythons are most common. A parasite called snake lungworm has made the problem even worse, now it’s killing native snakes across many Florida counties. Although more than 23,000 pythons have been removed, experts believe this represents only a small fraction of the total population. Removing them all is nearly impossible.

The article highlights how damaging an invasive species can be once it’s established and has a large population. I think the Burmese python is especially alarming because it has completely disrupted the food web of the Everglades and continues to threaten other endangered species, such as the Florida panther. It also shows how strict regulations are on exotic pet trades. Once an animal such as the pythons spreads, even advanced tools like public hunts and detection dogs are too slow to chip the problem. This example makes it clear again that early action is necessary, as are strong environmental policies, to prevent future invasions before they cause irreversible harm.

Fire ant invasion has reached a tipping point on Maui

Nolan, E. (2026, January 22). Fire ant invasion has reached a tipping point on Maui. Honolulu News from the States. https://www.newsfromthestates.com/article/fire-ant-invasion-has-reached-tipping-point-maui .

Little ants are among the world’s most invasive species and are now spreading rapidly across Maui, approaching a critical tipping point. The ants have been on the island for many years, but detections have risen in 2024 and 2025, including the recent discovery inside Waihe’e Coastal Dunes and Wetlands Refuge. These ants are a problem because they form massive colonies, deliver painful stings, and can severely harm wildlife, pets, agriculture, and also people. If they spread further and go unchecked, it could also harm Maui’s tourism industry, reduce biodiversity, and make outdoor activities unsafe. The Maui invasive species committee is working to stop the ants by using bait treatments, drones, helicopters, and even trained detection dogs. Although the work is very slow and expensive, it will pay off in the end. 

This article shows how invasive species can completely change a place if they are not stopped early. I think this situation is very alarming because the fire ants not only threaten the environment but also their everyday lives of these residents and tourists. Once these ants fully establish themselves, they are hard to get rid of, so this problem could last a very long time. This also highlights why involvement is so important. If people learn how to spot and report fire ants early, Maui still has a chance to protect its land and ecosystem before it’s too late.

‘Emerging threat’: An invasive species is upending life in the Delta, with no help on the way.

 

Becker, R. (2025, November 4). ‘Emerging threat’: An invasive species is upending life in the Delta, with no help on the way. CalMatters. https://calmatters.org/environment/water/2025/11/tiny-invaders-golden-mussels-delta/ 

 

Golden mussels, an invasive species native to Asia, have spread rapidly in the Delta in just 1 year. Thick colonies that cover boats, docks, and underwater pipes cause serious problems for water systems used by cities and farms. These muscles breed and multiply very quickly and can clog pumps and water intakes, putting many drinking water supplies and agricultural areas at risk. Farmers and water managers are now seeing many mussels piling up on equipment. The economic damage can be huge, since mussels already cost billions of dollars each year in lost productivity and repairs. Even though the invasion is growing rapidly, the state does not have a specific plan or funding to help the Delta deal with the damage.

 

The article shows how invasive species can cause major environmental and economic problems, especially when they are not addressed early on. I think it’s very concerning that this problem is being overlooked, even though it’s at the center of the invasion and a populated area with farms and ecosystems. The mussels threaten not only boats and other recreational activities, but also water supplies that millions of people rely on. If nothing is done, farmers could lose crops, cities could face higher water costs, and a lot of communities may be forced to relocate. This situation shows how important it is for the state and federal governments to act quickly and support local communities before problems become too big to handle.

 

Spread of Australia’s red fire ant population has sent 23 people to the hospital.

 Guy, J. (March 24, 2025). Spread of Australia’s red fire ant population has sent 23 people to the hospital, from https://www.cnn.com/2025/03/24/asia/australia-fire-ant-spread-hospitalization-intl 

In March of 2025, CNN reported that Australia is facing a surge in red imported fire ant attacks. In the latest month, 23 people have been hospitalized. These ants are originally from South America and are considered one of the most invasive species. These ants are capable of inflicting venomous stings that are painful while also leading to severe allergic reactions and even death. The recent spike in attacks has been connected to the torrential rains in Queensland, which forced the ants above ground, which in turn allowed them to spread into new areas. Residents have reported a lot of infestations that affect homes, farms, and pets, while the National Fire Ant Eradication program has logged over 60 severe stings that required medical attention.

This article highlights the broader threat that fire ants pose to Australia and its health, whether that be environmental or economic. The Queensland government has pledged 24 million Australian dollars to suppress the outbreak. They also warn that if an infestation is left unchecked, it could lead to devastating consequences for crops, wildlife, and outdoor lifestyles. Experts give caution that without an intervention, the ants could spread across the whole country, as modeling suggests they have the potential to colonize everywhere in Australia. Given their history of disrupting communities all over the world, the urgency of containing them in Australia also represents a global challenge.

 

. Federal cuts could impact Hawaiʻi’s ability to keep the brown tree snake away.

 Ladao, M. (March 4, 2025). Federal cuts could impact Hawaiʻi’s ability to keep the brown tree snake away, from https://www.hawaiipublicradio.org/local-news/2025-03-04/federal-cuts-could-impact-hawaiis-ability-to-keep-the-brown-tree-snake-away 

In March 2025, Hawai’i Public Radio reported that federal staffing and funding cuts threatened the state’s ability to keep the brown tree snake from going into the state. The Brown Tree snake was introduced to Guam in the 20th century, and this caused devastating ecological damage there. The snakes wiped out most of the native bird species and several lizard species, while also creating a lot of infrastructure problems, like power outages. If introduced to Hawai’i, the snake could do the same ecological damage as it did to Guam, with an estimated $593 million of economic losses. The snakes would have impacts on power, agriculture, tourism, and ecosystems. Efforts to prevent this from happening are already taking place, with most of the efforts being heavily contracted on USDA employees who are stationed in Guam and trap and remove snakes from cargo going to the US and Hawai’i.

This article shows the connection between invasive species control and a lot of broader federal policies. While some invasive species mitigation jobs were saved because of the connection to public safety and national security. Expats say that reduced federal support could increase risk not only from the brown tree snakes but also from other invasive species. The article highlights the fragility of prevention systems and the importance of consistent funding, while also having coordination and vigilance to protect Hawai’i’s ecosystems and economy. 

The Colorado River is officially positive for invasive zebra mussels.

May, H. (2025, July 22). The Colorado River is officially positive for invasive zebra mussels. Colorado Public Radio. https://www.cpr.org/2025/07/22/colorado-river-zebra-mussels/ 

 

Colorado Parks and Wildlife announced on July 3, 2025, that several new colonies of invasive zebra mussels were found in Eagle County along the Colorado River near New Castle and Highline Lake State Park, marking the river as officially positive for the species from Roring Fork River, which is north of Aspen, to the Colorado-Utah border. Zebra mussels, native to eastern Europe, first arrived in the U.S. in the late 1980’s are notorious for clogging water intake systems and altering ecosystems. They Reproduce Prolifically, can filter large volumes of water, which affects phytoplankton, and outcompete native species, threatening both the agriculture and recreational fisheries. Efforts to eradicate them, including lowering the water levels, applying EPA-approved molluscicides, and fully draining Highline Lake in 2024-2025, have met with limited success, demonstrating how difficult these invasive species are to control.

 

The article highlights the broader challenges of invasive species management and the importance of preventative measures. Colorado Parks and Wildlife continues to inspect boats, clean gear, and conduct regular testing to mitigate any further spread, and while federal funds from the EXPLORE Act could support any ongoing efforts. Zebra mussels’ impact extends beyond Colorado, affecting millions of people who rely on the Colorado River for clean drinking water, irrigation, and ecosystem health. The article underscores that vigilance, early detection, and consistent mitigation are essential to prevent any long-term ecological and economic damage from these invasive species.

Invasive carp threaten the Great Lakes − and reveal a surprising twist in national politics.

The Conversation (July 1, 2025) Invasive carp threaten the Great Lakes − and reveal a surprising twist in national politics, from https://theconversation.com/invasive-carp-threaten-the-great-lakes-and-reveal-a-surprising-twist-in-national-politics-233648 

 

In May 2025, President Donald Trump issued a memorandum supporting the construction of a $1.15 billion barrier at the Brandon Road Lock and Dam in Illinois. This barrier is designed to prevent invasive Asian carp from entering the Great Lakes. These carp, which have spread up the Mississippi River system after escaping many fish farms in the 1990, pose a serious ecological threat which may potentially make up to a third of Lake Erie’s fish Biomass within 20 years, and it will displace many native species, impacting the local economy. The project is funded by $226 million in federal money from the Bipartisan Infrastructure Law and $114 million in state funds from Michigan and Illinois, but the Illinois Governor JB Pritzker initially delayed key land purchases because the federal government was uncertain of it. On the other hand, Michigan Governor Gretchen Whitmer worked with the administration and praised the project, which eventually helped it move forward.

 

 This article highlights how invasive species management intersects with politics, revealing all of the unexpected support from sides that usually divide. While Pritzker’s adversarial stance was not the same as Whitmer’s, they both eventually contributed to restarting the project. The Great Lakes hold an importance for many Americans; they create a broad public support for environmental protection that bypasses political differences. This case shows how collaborative efforts focused on our environment can divide political forces for the greater good.

 

Cocaine Hippos: How drug-funded hippopotamuses are ruining Colombia.

 Issac(May 22, 202.5) Cocaine Hippos: How drug-funded hippopotamuses are ruining Colombia, from  https://www.palomaschool.org/secondary-students-blog/2025/5/22/cocaine-hippos-how-drug-funded-hippopotamuses-are-ruining-colombia 

 

A growing population of invasive hippos in Colombia, imported initially by the infamous drug lord Pablo Escobar for his private zoo, is now creating severe ecological and public safety problems. After the death of Escobar in 1993, the hippos escaped captivity and are rapidly breeding throughout Colombia. Currently, the estimated population of hippos is at 169, and the projected population is 1,000 by 2035. The Colombian government has implemented and 3-part plan to address the issue. First, they will sterilize each hippo at a cost of 10,000 dollars per hippo, then they will be relocated through numerous different countries with an estimated cost of 3.5 million dollars, but also sometimes consider euthanasia in rare cases. However, the plan faces many challenges because of the hippo’s huge popularity among the public and the media, legal protection under Colombian environmental law, and international animal rights campaigns opposing lethal control. Scientists warn that if the hippos spread throughout the Amazon basin, the ecological consequences may be severe and may affect many of the native species, water quality, and habitats on a massive scale.

 

This article sheds some light on how hard it is to manage invasive species, especially when most of the public opposes it. While hippos may look cute to the public, they are one of the most dangerous animals on the planet, and they can cause severe ecological damage outside of their native range. This article also raised questions about how the government will use the funding because the plan is not going to be cheap. It also made me wonder whether other political and social pressures may be affecting Colombia’s ability to address the problem more effectively. This situation seems to highlight the need for clearer policies on invasive species control and also balancing ethical treatments of the animals while also protecting native ecosystems.
