接着来。。。 United Kingdom 3 Britain Fights Ash Dieback（有没有官方的标准翻译） 英国防控梣树枯死病 The U.K. government banned the import of ash trees Monday in the face of a spreading fungal disease threatening Britain’s iconic ash woodlands. The fungus Chalara fraxinea causes ash dieback disease, which has devastated ash trees in Denmark and is spreading through central Europe. The fungus was detected in a Buckinghamshire nursery shipment（我翻成了进口树苗，对么？） from the Netherlands in February. 因为梣树真菌病威胁到了英国标志性的梣树林地，所以英国政府为了防止该真菌病的传播，周一禁止了梣树的进口。真菌Chalara fraxinea能引起梣树枯死，它已经席卷了丹麦，现在正在通过欧洲中部向外传播。今年2月份，这种真菌曾在Buckinghamshire从荷兰进口的树苗中检测出来。 In the following months, cases were identified in several other locations that had received recent tree imports. In late October, the U.K. Food and Environment Research Agency confirmed the disease in 10 woodland sites in East Anglia that had no known connection to nursery stock. 接下来几个月中，其他几个进口树苗的地方也检测到了同样的真菌。10月末，英国食品和环境研究中心确认East Anglia 十处林地的发病和苗圃存苗没有关系。 The U.K. Forestry Commission calls the fungus “potentially a very serious threat” to Britain’s ash trees, which make up about 5% of the country’s woodlands. C. fraxinea was first identified in Poland in 1992, but researchers aren’t sure where it originated. 英国森林委员会称，此种真菌对于占全国5%林地的梣树来说，是潜在的严重威胁。早在1992年，波兰首先检测出C. fraxinea真菌，但是研究者们现在依然不确定它当时到底来自何方。 |
