"Hidden Threat: Invasive 'Time Bomb' Plants Invade US Ecologies"

Invasive plants, such as ribwort and velvetleaf, are causing ecological havoc in the U.S. as they can remain dormant for decades before suddenly expanding. These plants outcompete native species, attract pollinators away from them, and threaten agricultural crops. The long dormancy period of invasive plants makes it difficult to predict and prevent their spread, highlighting the need for policies and risk assessments that consider this lag phase. Understanding the reasons for these delays, such as climate suitability, is crucial for managing pests and preventing widespread invasion and economic losses in the future.

"The Looming Ecological Threat of Invasive Plant Time Bombs"

A new study led by the University of California, Davis reveals that invasive plants can remain dormant for decades or even centuries before rapidly expanding and causing ecological damage. The research, published in Nature Ecology and Evolution, analyzed over 5,700 species of invasive plants in nine regions globally, finding that nearly one-third exhibited lag periods between introduction and rapid expansion, with the average time being 40 years. The study emphasizes the need to consider dormancy periods in managing pests and preventing widespread invasion and economic losses in the future.

"Gardening Solutions for Northeast Ohio's Invasive Species Crisis"

Arborist and horticulturist Eddie Lagucki explores the devastation caused by emerald ash borers, invasive plants, and deer in Northeast Ohio woods. Lagucki recommends a restoration approach involving killing invasives, installing deer fences, and eventually replacing plants, emphasizing the need for time, planning, and resources. Despite the challenges, signs of hope for forest recovery are evident, with native plants beginning to assert themselves in cleared areas.

The Powerful Role of Large Herbivores in Controlling Invasive Plants

A study from Aarhus University and the Wildlife Institute of India reveals that large herbivores, such as elephants and rhinos, can help protect native plants by eating and trampling on invasive plant species. Native plants have evolved to withstand the impact of herbivores they coexist with, while invasive plants typically cannot. The research suggests that using large herbivores as a natural weapon can prevent invasive plants from outcompeting native species. The study's findings are relevant not only in India but also in other areas with herbivores of varying sizes.

The Science Behind the Intensified Allergy Season

Warm weather has caused an explosion of pollen levels this spring, causing allergies to worsen in some parts of the US. Oak trees in the Southeast are contributing to record-high levels of pollen early in the season. Invasive plants such as Dalmatian toadflax and Johnsongrass can also trigger allergies and aggravate hay fever. Pollen from weeds, grasses, and trees are the primary sources of pollen that can cause allergies.
