       "content":" Almost 600 plant species have been wiped from the planet in the past 250 years, more than twice the number of bird, mammal and amphibian species that have met the same fate, according to a new study.The research -- published Monday in Nature, Ecology & Evolution journal -- found that 571 plant species have disappeared from the wild worldwide, and that plant extinction is occurring up to 500 times faster than the rate it would without human intervention.For comparison, the researchers said animal extinction is occurring at least 1,000 times faster than the normal rate of extinction, however the report notes that researchers believe the plant extinction rate has been underestimated. The Royal Botanic Gardens, Kew and Stockholm University researchers say it's the first time scientists have compiled a global overview of which plants have already become extinct. Most people can name a mammal or bird that has become extinct in recent centuries, but few can name an extinct plant, report co-author Aleys Humphreys said. Plants on islands, in the tropics and in Mediterranean climates had the highest rates of plant extinction, as these were areas home to unique species vulnerable to human activities. The study said the increase in the plant extinction rate could be due to the loss of habitat of species located in a small geographic area. Some examples of plants that have gone extinct in the past two centuries are the aromatic Chile sandalwood and the banded trinity, which has no leaves -- only its flowers are visible above the ground."
