Invasive species are taking over some American forests

Invasive species are taking over some American forests

A new botanical survey in southwestern Ohio has found that invasive species introduced to the United States last century crowded out a return of native plants.

Biologists from the University of Cincinnati are tracking down two comprehensive surveys conducted 100 years apart to see how Queen City's flora has changed over the course of the two educational centuries. and Mill Creek banks and parks that dot public oceans.

The study, titled "The Rise of Native Plants in Wooded Landscapes in Southwest Ohio," is published in June in the journal Ecological Restoration.

At that time, based on that time, based on that time, based on that time, based on that email in Cincinnati, and Oceanography in Philadelphia. Leah identified about 714 species before his death in 1844. His brother in 1849.

A century later, famed UCLA botanist E. Lucy Brown retraced Leah's path, conducting a second survey in Cincinnati and finding more than 1,400 species in her 1934 study published in America's Midland Nature. I based certain topics on certain topics in topical places.

Biologist Dennis Conover and co-author Robert Bergstein traced Brown and Leah's footsteps in southwest Ohio to places where natural city development did not pave the way. A species intentionally introduced as landscape plants thrives in the wild.

The spread of native invasive species in wooded areas of southwestern Ohio continues the survival of native flora and fauna. Both financially and temporally due to the damage to native plants, wildlife, and humans caused by intensive herbicides, mines, and other mechanical equipment.”

Horticulturalists introduced most of the native plants from Europe and Asia as ornamentals. in the wild.

The biggest culprit? Amur honeysuckle is a woody woodland captured from the eastern forests.

"It escaped into the wild and spreads on its own," said Conover, a professor of biology at the University of California College of Arts and Sciences.

How about confused with the native honeysuckle, which grows in the southern states and is referenced in the works of Americans William Faulkner and Rust Frost, Amur honeysuckle is a shrub from Asia with delicate white flowers in spring and red berries in fall.

He claims that "Amur honeysuckle is now the most abundant woody plant in Hamilton County." "One ready-made bush can have the first thousands of seeds scattered."

The existing survey found parts spread to other Ohio counties. The study found that today it is a dominant woody plant that is ubiquitous throughout the state, crowding out all other cars.

"The larger trees grow above the shrub layer," the study said.

"It opens leaves with native plants and keeps its available leaves longer in the fall," Conover said.

He said that some invasive plants are successful

Conover said it's natural I copy, copy, copy, root, root, root, root, yeast, I tried.

"Native plants have no chance," Conover said. "Everything that depends on native plants — and birds — may perish." "When non-native plants are introduced into the United States, they bring with them fungal diseases that can wipe out native trees, as the American chestnut did."

Pear trees with their beautiful spring flowers and rapid growth times have been the preferred tree for planting in the front yards of the new subdivisions. Today, it grows wild along highways and forests.

Imposing the imposition of the sale of pear trees on the sale of pear trees.

The California survey found dozens of other genera for foreign markets that took root in the forests of southwestern Ohio, including porcelain berry, paradise tree, oriental bitter, common sage, and lesser periwinkle. Norway also found maple, amur cork tree, and white poplar along with herbal species such as minor mustard, mustard, garlic, Japanese herbs, and Japanese herbs.
