The giant carnivorous plant, Nepenthes attenboroughii, is among those facing extinction.
One in five of the world's plant species – the basis of all life on earth – are at risk of extinction, according to a landmark study published today.
At first glance, the 20% figure looks far better than the previous official estimate of almost three-quarters, but the announcement is being greeted with deep concern.
The previous estimate that 70% of plants were either critically endangered, endangered or vulnerable was based on what scientists universally acknowledged were studies heavily biased towards species already thought to be under threat.
Today the first ever comprehensive assessment of plants, from giant tropical rainforests to the rarest of delicate orchids, concludes the real figure is at least 22%. It could well be higher because hundreds of species being discovered by scientists each year are likely to be in the "at risk" category.
"We think this is a conservative estimate," said Eimear Nic Lughadha, one of the scientists at Kew Gardens in west London responsible for the project.
The plant study is also considered critical to understanding the level of threat to all the natural world's biodiversity, said Craig Hilton-Taylor of the International Union for the Conservation of Nature (IUCN), which runs the world's offical "red list" of threatened species. "Plants are the basis of life, and unless we know what's happening to plants it has many implications," said Hilton-Taylor.
Flowering plants not doing well, either
More than one-in-four of all flowering plants are under threat of extinction according to the latest report to confirm the ongoing destruction of much of the natural world by human activity.
As a result, many of nature's most colourful specimens could be lost to the world before scientists even discover them, claims the research, published today in the journal Proceedings of the Royal Society B.
The results reflect similar global studies of other species groups by the International Union for the Conservation of Nature, which estimates that one-in-five of all mammals, nearly one-in-three amphibians and one-in-eight birds are vulnerable to being wiped out completely. Later this year the results of a huge global analysis of all the world's estimated up to 400,000 plants by Royal Botanic Gardens, Kew, is due to be published by the IUCN as part of its ongoing mission to assess the state of all life on Earth.
"[This year] marks the International Year of Biodiversity," said Stuart Pimm of Duke University in North Carolina, USA, one of the authors of the report. "The focus of this celebration has often been on the species we know of, along with discussions on the unprecedented challenge of conserving this biodiversity in the face of threats such as habitat loss. However, by asking just how many species we will lose before they are even discovered, our study has revealed a figure that is truly alarming."
What an FBI fishing expedition is like
Options? Disperse tools. Duplicate text records and working materials. Stash them off-site, with a trusted colleague. That way, if govt agents break in and confiscate you have an alternative operating base to fire up and continue.
Today one must assume surveillance and act accordingly.
