摘要：
美国陆军工程兵团以及其它政府研究人员发布了一份1500页的环评报告，这份报告历时5年，里面分析说明外来物种入侵的可能性极低。
但一个牡蛎养殖人员通过阅读该报告，发现其中存在重大数学模型错误，直接导致外来牡蛎入侵海外的可能性大大增加。。
不知环评人员此时的心情。。。
EIS Math Error May Underestimate Risk of Cheseapeake Oyster Introduction
March 04, 2009 -- The five-year review of oyster management options appears to have massively underestimated the likelihood that sterilized foreign oysters used in aquaculture would lead to the accidental introduction of breeding populations into the Bay.
Last October, the Army Corps of Engineers and the states of Maryland and Virginia released a 1,500-page Environmental Impact Statement that analyzed the risks and benefits of various oyster management alternatives aimed at restoring the ecological and economic role of oysters in the Bay.
Among the options analyzed was the potential for using nonnative C. ariakensis oysters, which have shown resistance to diseases that plague the Bay's native C. virginica oysters. One alternative called for large-scale aquaculture using sterilized nonnative oysters.
The EIS said the risk "appears to be small" that the sterile oysters would lead to the accidental introduction of reproductive nonnative oysters in the Chesapeake.
But a Maryland oyster gardener who reviewed the 1,500-page document discovered huge math errors in the EIS which, when corrected, suggested that an introduction of the foreign species would be inevitable from the large-scale aquaculture option. Read the full story to get the details. |
