Scientists found that more than 50% of plant species in the world were discovered by 2% of plant collectors. At present, there are still 15-30% flowering plants in the world that have not been discovered, so it is very important for people to understand the global biodiversity by discovering and recording new plant species. Recently, scientists at Oxford University found that modern botany was dominated by a group of "great plant gatherers", whose experience and skills made them make great contributions to the discovery of new species. The research report was published on February 6, 2008 in the Proceedings of the Royal Society Series B.. "Even in the 2 1 century, we still need experienced and skilled plant gatherers to make effective use of their time in the wild," said RobertScotland, a researcher in the Department of Plant Science at Oxford University. "At the same time, local experts, science lovers and students have also made inestimable contributions to botany. Our research shows that years of experience will help collectors collect plants, not necessarily more plant specimens, but it is very important to change people's understanding of plant species, "Scotland added. "In the databases of British Museum of Natural History, Edinburgh Royal Botanical Garden, Missouri Botanical Garden and Melbourne Royal Botanical Garden in Australia, 654.38+ten thousand specimens were investigated. It is suggested that researchers should make more efforts in identifying, cultivating and supporting plant collectors, so that plant collectors can make greater contributions to the discovery of new plant species.
