Oriental Bittersweet was an exotic foreigner still found mostly in East Asia when the New York Botanical Garden planted its first specimen in 1897.
Today, it is everywhere. The shrubby vine is common in woodlands and fields in 21 states, ranging from North Carolina, to Maine, to Illinois.
The American Bittersweet, meanwhile, has been in a slow decline.
Once common across the eastern two-thirds of the US, the native version of the plant is still around, but it has vanished from many areas now dominated by its hardier, faster-breeding Asian cousin.
“We go entire seasons now without seeing it,” said Gerry Moore, director of the science department at the Brooklyn Botanic Garden.
The rise and fall of the two plants has been chronicled by the Botanic Garden as part of a 20-year study that offers a dispiriting outlook on the future of some native flora.
So far, the project has identified 50 native species that have disappeared from metropolitan New York during the last 100 years, and others that have become far less abundant because of factors including the destruction of their habitat, pollution and competition from foreign interlopers.
In some areas, the landscape is also becoming less biologically diverse.
“While you used to have a marsh of 50 or 60 species, you might now have an entire marsh of phragmites, the common reed,” Moore said.
The study focused on counties within 80km of New York City, but experts say other scientists have made similar findings nationwide.
In the West, sagebrush has been giving way to cheatgrass, which found its way to the US in packing materials and ship ballast in the late 1800s.
Nature lovers strolling through wooded glades, thinking they are among trees that have stood since the Revolution, are actually looking at Norway Maple native to Europe.
Kudzu, which hails from Japan and China, infested the South after farmers in the 1930s through the 1950s were encouraged to use it to stop soil erosion.
Even the pristine open spaces of Grand Teton National Park in Wyoming are now populated with Houndstongue and Yellow Toadflax, both from Europe.
Bit by bit, scientists say, the American landscape is becoming less American.
“We are going to our national parks now and seeing Europe,” said Tom Stohlgren, a research ecologist for the US Geological Survey. “We are homogenizing the globe at a very fast rate.”
Experts say the trend has many causes, but the biggest one may turn out to be globalization.
European traders and settlers have been bringing Old World plants to the Americas since colonization, but the process has accelerated with every advance in travel.
Now, foreign species arrive so frequently aboard planes, trucks and cargo ships that the odds of the next Oriental Bittersweet arriving are exponentially greater.
“That’s the scary part, and the US$64,000 question,” Stohlgren said. “What we have had is an explosion in trade and transportation, and we have yet to see the full effect of that.”
THE ‘MONSTER’: The Philippines on Saturday sent a vessel to confront a 12,000-tonne Chinese ship that had entered its exclusive economic zone The Philippines yesterday said it deployed a coast guard ship to challenge Chinese patrol boats attempting to “alter the existing status quo” of the disputed South China Sea. Philippine Coast Guard spokesman Commodore Jay Tarriela said Chinese patrol ships had this year come as close as 60 nautical miles (111km) west of the main Philippine island of Luzon. “Their goal is to normalize such deployments, and if these actions go unnoticed and unchallenged, it will enable them to alter the existing status quo,” he said in a statement. He later told reporters that Manila had deployed a coast guard ship to the area
A group of Uyghur men who were detained in Thailand more than one decade ago said that the Thai government is preparing to deport them to China, alarming activists and family members who say the men are at risk of abuse and torture if they are sent back. Forty-three Uyghur men held in Bangkok made a public appeal to halt what they called an imminent threat of deportation. “We could be imprisoned and we might even lose our lives,” the letter said. “We urgently appeal to all international organizations and countries concerned with human rights to intervene immediately to save us from
RISING TENSIONS: The nations’ three leaders discussed China’s ‘dangerous and unlawful behavior in the South China Sea,’ and agreed on the importance of continued coordination Japan, the Philippines and the US vowed to further deepen cooperation under a trilateral arrangement in the face of rising tensions in Asia’s waters, the three nations said following a call among their leaders. Japanese Prime Minister Shigeru Ishiba, Philippine President Ferdinand Marcos Jr and outgoing US President Joe Biden met via videoconference on Monday morning. Marcos’ communications office said the leaders “agreed to enhance and deepen economic, maritime and technology cooperation.” The call followed a first-of-its-kind summit meeting of Marcos, Biden and then-Japanese prime minister Fumio Kishida in Washington in April last year that led to a vow to uphold international
US president-elect Donald Trump is not typically known for his calm or reserve, but in a craftsman’s workshop in rural China he sits in divine contemplation. Cross-legged with his eyes half-closed in a pose evoking the Buddha, this porcelain version of the divisive US leader-in-waiting is the work of designer and sculptor Hong Jinshi (洪金世). The Zen-like figures — which Hong sells for between 999 and 20,000 yuan (US$136 to US$2,728) depending on their size — first went viral in 2021 on the e-commerce platform Taobao, attracting national headlines. Ahead of the real-estate magnate’s inauguration for a second term on Monday next week,
