在密西西比河中部的亚祖河畔,一队地质工作者和来自蒙大拿公司的科学家沿着已受侵蚀的河岸栽种柳树和梧桐树。这些树桩是从附近的沙洲运来的,而且应该赶在春雨使河水暴涨之前种植。一些树桩通常被捆绑在一起,并且被停放在河边。在较远的下游,工作队伍将优质的强化纤维席子放置在细碎的土壤上,然后将席子用活树桩锚固。正在施行的名为“半英里计划”将采用不妨碍生态环境的新技术方式,目的是取代 On the Yazoo River in the middle of the Mississippi River, a team of geologists and scientists from the Montana Company planted willow and sycamore trees along an eroded riverbank. These stumps are transported from nearby sandbanks and should be planted just before spring rains soar. Some stumps are usually tied together and parked by the river. Farther downstream, the team placed high-quality fiber mats on finely divided soil and anchored the mats with live stumps. The ongoing program called “Half Mile Plan” will adopt a new technological approach that does not interfere with the ecological environment in order to replace
