Seed Hunting

With quarter of the world's plants set to vanish within thenext 50 years, Alexander reports on the scientists working againstthe clock the preserve the Earth's botanical heritage. They travelthe four comers of the globe, scouring jungles，forests andsavannas. But they‘re not looking for ancient artefacts，losttreasure or undiscovered tombs. Just pods. It may lack theromantic allure of archaeology, or the whiff of danger thataccompanies going after big game, but seed hunting is an

increasingly serious business. Some seek seeds for profit huntersin the employ of biotechnology firms，pharmaceutical

companies and private corporations on the lookout for speciesthat will yield the drugs or crops of the future. Others collect toconserve, working to halt the sad slide into extinction facing somany plant species.

Among the pioneers of this botanical treasure hunt was JohnTrade scant, an English royal gardener who brought back plantsand seeds from his journeys abroad in the early 1600s. Later，the English botanist Sir Joseph Banks-who was the first director

of the Royal Botanic Gardens at Kew and travelled with CaptainJames Cook on his voyages near the end of the 18th

century—was so driven to expand his collections that he sentbotanists around the world at his own expense.

Those heady days of exploration and discovery may be over,but they have been replaced by a pressing need to preserve ournatural history for the future. This modem mission drives hunterssuch as Dr Michiel van Slageren，a good-natured Dutchman whooften sports a wide-brimmed hat in the field一he could easily bemistaken for the cinematic hero Indiana Jones. He and threeother seed hunters work at the Millennium Seed Bank，an 80million [pounds sterling] international conservation project thataims to protect the world's most endangered wild plant species.

The group's headquarters are in a modem

glass-and-concrete structure on a 200-hectare Estate atWakehurst Place in the West Sussex countryside. Within itsunderground vaults are 260 million dried seeds from 122countries, all stored at -20 Celsius to survive for centuries.Among the 5，100 species represented are virtually all ofBritain's 1,400 native seed-bearing plants, the most completesuch collection of any country‘s flora.

Overseen by the Royal botanic gardens, the Millennium SeedBank is the world's largest wild-plant depository. It aims tocollect 24,000 species by 2010. The reason is simple: thanks tohumanity’s efforts，an estimated 25 percent of the world'splants are on the verge of extinction and may vanish within 50years. We're currently responsible for habitat destruction on anunprecedented scale，and during the past 400 years，plantspecies extinction rates have been about 70 times greater thanthose indicated by the geological record as being ‘normal’.Experts predict that during the next 50 years a further one billionhectares of wilderness will be converted to farmland in

developing countries alone.

The implications of this loss are enormous. Besides providingstaple food crops，plants are a source of many machines and theprincipal supply of fuel and building materials in many parts ofthe world. They also protect soil and help regulate the climate.Yet，across the globe，plant species are being driven toextinction before their potential benefits are discovered.

The world Conservation Union has listed 5,714 threatenedspecies is sure to be much higher. In the UK alone, 300 wild plantspecies are classified as endangered. The Millennium Seed Bankaims to ensure that even if a plant becomes extinct in the wild，itwon‘t be lost forever. Stored seeds can be used the help restoredamaged or destroyed environment or in scientific research tofind new benefits for society- in medicine, agriculture or localindustry- that would otherwise be

Seed banks are an insurance policy to protect the world’splant heritage for the future, explains Dr Paul Smith，anotherKew seed hunter. "Seed conservation techniques were originallydeveloped by farmers，" he says. "Storage is the basis what wedo，conserving seeds until you can use them-just as in farming."Smith says there's no reason why any plant species should

become extinct，given today’s technology. But he admits thatthe biggest challenge is finding，naming and categorising all theworld's plants. And someone has to gather these seeds beforeit’s too late. "There aren't a lot of people out there doingthis，" he says." The key is to know the flora from a particulararea, and that knowledge takes years to acquire."

There are about 1,470 seed banks scattered around theglobe，with a combined total of 5.4 million samples，of whichperhaps two million are distinct non-duplicates. Most preservegenetic material for agriculture use in order to ensure crop

diversity; others aim to conserve wild species，although only 15

per cent of all banked plants are wild.

Many seed banks are themselves under threat due to a lackof funds. Last year, Imperial College, London，examined cropcollections from 151 countries and found that while the numberof plant samples had increased in two thirds of the

countries，budget had been cut in a quarter and remained staticin another 35 per cent. The UN's Food and Agriculture

Organization and the Consultative Group on International

Agricultural Research has since set up the Global …… 此处隐藏：5800字，全部文档内容请下载后查看。喜欢就下载吧 ……
