Monday 20 September 2010 14.46 BST In 1929, Russian botanist Nikolai Vavilov traveled to Central Asia on one of the many seed-collecting expeditions that took him to five continents over more than two decades. In what is now present-day Kazakhstan, Vavilov — the father of modern seed banks — found forests of wild fruits and numerous cultivated varieties. Around the city of Alma Ata, he was astonished by the profusion of apple trees, writing in his journal that he believed he had “stumbled upon the center of origin for the apple, where wild apples were difficult to even distinguish from those which were being cultivated.” Correctly surmising that this region of Kazakhstan was “the chief home of European fruit trees,” Vavilov collected the seeds of the many varieties of apple and other trees, eventually hauling them back to his scientific base in Leningrad, now St. Petersburg. The trees that sprouted from those seeds, and more than 5,000 other varieties of fruits and berries, now grow in a sprawling, 1,200-acre collection of fields about 20 miles south of St. Petersburg, not far from the opulent, 18th-century czarist palace of Pavlovsk. This living repository of trees and bushes — with Europe’s most extensive collection of fruits and berries — has been at the center of a dispute in recent months as a federal Russian housing agency has tried to confiscate part of the Pavlovsk Research Station to clear the land for upscale dachas for Russia’s burgeoning new elite. The fate of the station is now in limbo as, after an intense lobbying campaign by botanists and conservation groups around the world, Russian President Dmitri Medvedev has announced that the government is investigating the effort to uproot one of the most valuable botanical collections on Earth. The priceless nature of the Pavlosk station can be traced directly back to Vavilov and his painstaking efforts to collect seeds from what he viewed as hot spots of plant diversity around the world, now known as Vavilov Centers. His insights into the importance of preserving botanical genetic diversity, particularly among food crops, are highly relevant today as that diversity faces unparalleled threats from industrial agriculture dominated by monoculture crops, destruction of wild habitats, and climate change. The Pavlovsk Research Station, part of the N.I. Vavilov Research Institute of Plant Industry, houses one of the world’s largest collections of seeds and planted crops, roughly 90 percent of which are found in no other scientific collections in the world. … Cary Fowler, an American conservationist who runs the Global Crop Diversity Trust in Rome, Italy, visited the station earlier this year. He says the loss of the collection would be “the largest intentional, preventable loss of crop diversity in my lifetime.” …
