Kenya’s government has launched an ambitious plan to eradicate one million Indian crows by the end of 2023, citing their disruptive presence and impact on local bird populations, the hospitality industry, and farmers. The move follows a previous attempt to control the crow population two decades ago and comes with concerns regarding the methods used for extermination, including poisoning.
A new study has revealed the potential for an invasion of feral ‘super pigs’ into the northern United States from Canada. These pigs, a hybrid of domestic swine and wild boar, have thrived in the harsh Canadian climate, exhibiting high reproductive rates, mobility, and resistance to cold temperatures. Their rapid expansion across Canada has raised concerns about their potential ecological impact, including damage to agricultural production and ecosystems. The study’s findings have identified areas vulnerable to pig expansion, such as wetlands, deciduous forests, and border regions, highlighting the need for proactive mitigation strategies to prevent their spread.
Rhododendrons, once a popular garden ornamental, have become an invasive species in the UK, threatening native plant species and rare temperate rainforests. The Woodland Trust warns against buying and planting the invasive species Rhododendron ponticum, which spreads rapidly and can form dense thickets, blocking out sunlight for other plants. The plant is toxic to humans and livestock, and any pruning or waste material must be disposed of responsibly. Britons are encouraged to avoid this species and opt for other rhododendron varieties that are less invasive. Meanwhile, another invasive plant, Japanese knotweed, also poses a significant problem and should be tackled by professionals using herbicide treatment during its active growing season.
The Los Angeles County Board of Supervisors voted unanimously against a plan to eradicate the invasive mule deer population on Catalina Island using helicopter-mounted sharpshooters. The Board, led by Supervisor Janice Hahn, who represents Catalina Island, cited concerns from constituents and the availability of alternative solutions such as relocation, extended hunting season, and sterilization. The Catalina Island Conservancy, which proposed the plan to protect native species, says the deer population has overgrazed vegetation and outcompeted endemic animals. However, the Board urged the Conservancy to reconsider and explore less controversial options.
Houndstongue, a plant native to Europe and Asia, has become prevalent in much of the United States, Canada, and other parts of the world. While its unique funnel-shaped flowers may attract attention, the plant is known for its annoying seeds, which can cling to animals and humans, causing irritation. Beyond its physical discomfort, houndstongue also produces pyrrolizidine alkaloids (PAs), toxic compounds that can damage the liver and other organs in herbivores and even humans. Despite its negative aspects, the efficacy of houndstongue’s defenses has contributed to its successful invasion of various regions.
The United Kingdom is facing a surge in Asian hornet sightings, raising concerns about the potential impact on the country’s environment and wildlife. These invasive insects, known for their ability to decimate entire beehives, have seen a dramatic increase in reported encounters in recent years, from just two in 2022 to 78 in 2023, representing a staggering 3,800% increase. The Department of Environment, Food and Rural Affairs (Defra) has pledged to eradicate any nests found to prevent their establishment in Britain. However, the British Beekeepers Association has already reported four sightings this year, highlighting the urgent need for vigilance.
The number of Asian hornets in the UK is expected to surge in the coming weeks, sparking concerns of widespread devastation for beehives. The invasive species, known for its aggressive behavior and ability to decimate bee colonies, is poised for a comeback after a 3,800% increase in sightings last year. Experts warn that the hornets could multiply exponentially, threatening the livelihoods of beekeepers and the health of the ecosystem.
The spongy moth, a destructive invasive species, poses a significant threat to Illinois trees. It defoliates large swaths of land, while the spotted lanternfly damages crops and other plants. Both species lay eggs in masses, making early detection and eradication crucial. Residents are urged to report any sightings and dispose of egg masses to prevent the spread of these harmful insects.
Millions of spotted lanternflies are expected to emerge in New Jersey in early May, following a decrease in sightings in the western part of the state in 2023. The invasive insect, native to Asia, has established populations in every county in New Jersey, with officials expecting the infestation to continue moving eastward. While eradication is not feasible, the state is focusing on managing the population through treatments at seaports and transportation corridors, as well as reimbursements for local treatment programs. Residents are encouraged to stomp out spotted lanternflies and scrape off egg masses, which can harbor 30-50 nymphs each.
