觀賞植物擴散成威脅

最近一項在美國俄亥俄州西南部的研究發現,金銀忍冬等入侵植物已蔓延到野外,並威脅到當地原生動植物的存活率。金銀忍冬於美國是原自歐洲及亞洲的觀賞植物,但已成為入侵植物。它的果實非常吸引雀鳥食用,並將種子散佈到新的地方。 在俄亥俄州一些林地,金銀忍冬已生長得非常茂密,只有一些生長在灌木層之上的原生樹能存活下來。

A recent study in southwest Ohio discovered that invasive plants like Amur honeysuckle, are spreading into the wild and is threatening the survival of native plants and wildlife. Amur honeysuckle is an ornamental plant native to Europe and Asia, but has became an invasive plant in the US. It has fruits that are attractive to birds to consume and help it disperse the seeds to new locations. in some woodlands, Amur honeysuckle is so dense that only some native trees that grow above the shrub layer survive.
