Unveiling the Menace: The Battle against Invasive Species - Innovative Strategies Revealed!

Adam Larson, a writer and science communicator from Kenosha, Wisconsin, shares his views on invasive species in the United States. While there are numerous invasive species, the spotted lanternfly stands out as it has been featured on Saturday Night Live. This particular species is well-known due to its distinct appearance and can be easily identified by the average hiker or homeowner. Furthermore, individuals can take satisfaction in crushing them, as it gives them a sense of contributing to the environment.

The joy derived from eradicating is not something that can be said about the arduous task of removing kudzu, an invasive plant from Japan and southeast China that has been spreading for more than a century.

The emerald ash borer, a devastating invasive insect in Wisconsin, originates from eastern Russia and northern China. Despite its striking green appearance as an adult, it predominantly remains concealed within the bark of ash trees, often going unnoticed. Regrettably, this pest is responsible for the demise of 99% of the ash trees it infests.

Another troublesome invasive species found in the United States is the wild boar, which unfortunately cannot be easily defeated due to its large size. Also referred to as feral pigs, they naturally belong to Europe and Asia and have been known to grow up to three feet in height, six feet in length, and weigh over 500 pounds. Engaging in a confrontation with these creatures may result in dire consequences, as they are prone to retaliate vigorously.

According to a recent report supported by the United Nations, the US alone is home to numerous invasive species. The report highlights that these invasive species have a significant economic impact, costing the global economy a minimum of $423 billion per year. This financial burden, in turn, contributes to the depletion of plant and animal species, poses a threat to our food production, and exacerbates environmental disasters on a global scale.

Approximately 200 new species of aliens are identified each year, according to scientists, largely due to human travel and global trade. Out of the 37,000 introduced alien species worldwide, around 3,500 are deemed to pose a significant global threat. These species not only harm crop production, but also lead to the extinction of native species, water pollution, disease transmission, and the potential for catastrophic natural disasters.

While they may not be the most destructive, lanternflies receive considerable attention due to their vibrant appearance and visibility. However, spotted lanternflies go beyond simply being a nuisance. Since there are few natural predators to control their population, these insects can rapidly multiply and devastate numerous plant species, including economically important ones like apples, grapes, and hops.

As a naturalist and science writer, I must confess that I have yet to personally encounter a spotted lanternfly, despite reading about them extensively in the news. In Wisconsin, it may take a few more years for their arrival, or they may never reach this area at all. However, there is always the possibility that they could unexpectedly arrive in a shipment of tires tomorrow. This unpredictability is characteristic of invasive species, as their invasion can often go unnoticed.

What's intriguing is that even in areas where the infestation of spotted lanternflies has been severe, the damage to foliage has sometimes been less than anticipated. Additionally, in certain places where there was a significant infestation last year, detecting the presence of spotted lanternflies this year has proven to be difficult. However, it is important to note that it may take time before we can fully understand the long-term impacts of this infestation once spotted lanternflies establish themselves.

Schools are embracing eco-friendly practices during the festive season. In a bid to combat the climate crisis, eco-conscious students, parents, and teachers are calling for more action. To this end, schools have decided to ban non-biodegradable glitter and are considering eliminating Christmas crackers from the celebrations. One school encouraged students to participate in a Christmas jumper swap instead of purchasing new ones, while another opted to reuse or recycle nativity scenery and costumes. These initiatives promote environmentally friendly practices within the education system. For more information, refer to PA story EDUCATION Environment.

The Mid-Atlantic, the Midwest, and the West Coast are the main regions where spotted lanternflies are commonly found. However, the western US has limited suitable habitats for them, which acts as a natural obstacle to prevent their migration from one coast to another.

Nevertheless, human activities can alter this situation. The daily movement of numerous vehicles across the country creates opportunities for spotted lanternflies to bypass unsuitable environments and reach areas where they can thrive.

As the message has been reiterated countless times, dealing with spotted lanternflies involves various methods such as squishing, vacuuming, trapping, or crushing their eggs. Despite numerous people employing these actions in the previous year, the spread of the spotted lanternfly continues. However, amidst the concerning expansion of these insects and the extensive media coverage they have received, there is one positive aspect. It has presented us with a valuable opportunity to comprehend the mechanisms behind the proliferation of invasive species and the measures we must undertake to thwart future invasions of foreign flora or fauna.

To prevent the spread of invasive species, we can take certain measures, such as incorporating native plants into our gardens, refraining from releasing unwanted exotic pets, and vigilantly monitoring for any emerging populations of invasive species. However, it is important to note that importing natural predators from Asia to combat the spotted lanternfly in the United States is not a viable solution. This approach has proven detrimental in the cases of the cane toad, which was initially introduced to control native pests in Florida and Australia. Unfortunately, the cane toad became invasive in both regions, causing extensive harm to indigenous species and endangering numerous native predators through its toxic skin secretions.

Several counties that have reported spotted lanternfly infestations are located close to each other, while others are far apart, possibly hundreds of miles from the nearest infestation. This discrepancy could be due to unreported infestations in certain counties. Alternatively, it is also likely that, similar to how lanternflies were introduced to North America from Asia through shipments, they have also spread within the United States, "leapfrogging" from one location to another.

Fortunately, invasive species have occasionally been eradicated, bringing some hope. Islands have seen success in removing invasive species, resulting in significant recoveries in their ecosystems.

Unfortunately, eliminating invasive species on mainlands is considerably more challenging. However, with early detection, it is possible: an isolated group of feral pigs was successfully eradicated in Crawford County, Wisconsin thanks to educated deer hunters who understood the harmful impact caused by these pigs. Yet, when dealing with small species that can evade detection and reproduce rapidly, like many invasive species, the likelihood of achieving such results decreases significantly.

While it may take years for California to experience a spotted lanternfly infestation, there is a possibility that these destructive insects could already be present in a shipment heading to the West Coast. Studies indicate that they may establish themselves in California by 2033, but the unpredictable nature of their spread makes it difficult to accurately predict. This could pose a significant threat to the state's renowned vineyards, which would be an ideal target for these highly voracious pests.

If you reside in an area where spotted lanternfly thrives, familiarize yourself with its characteristics and egg masses. Taking prompt action and informing the appropriate authorities can help prevent an infestation from establishing itself. It is important to understand that effectively eradicating invasive species requires coordinated and sustained efforts over several years. While squashing some spotted lanternflies on the sidewalk may provide some relief, it alone is insufficient to eliminate the entire population.

Ultimately, addressing the issue of invasive pests necessitates a regional approach. It is likely that lanternflies, like many other invasive pests, will eventually become another alien species that farmers, gardeners, and the general public will need to learn how to manage.
