This article provides a detailed account of the shifting places of the black Locust tree (Robinia pseudoacacia) in France, from its introduction as a North American exotic in the early seventeenth century to the present. Three phases or moments are identified, articulating material and discursive dimensions of the trajectory of the tree — and of the spaces where it became prominent: exhortation, instrumentalization and marginalization. Due to a long introduction timeline and unmatched levels of expectations for versatility, the intertwined social-ecological dynamics of black Locust are marked by several reframings and rediscoveries. As such, a geohistorical focus on French ‘acacia’ landscapes offers an original window on the political economies of past and ongoing regional forest transitions of Western Europe.

这篇文章详细介绍了法国刺槐树 ( Robinia pseudoacacia ) 从 17 世纪初作为北美异国情调引入到现在的迁移地点。确定了三个阶段或时刻，阐明了树轨迹的材料和话语维度——以及它变得突出的空间：劝告、工具化和边缘化。由于引入时间很长，而且对多功能性的期望水平无与伦比，黑蝗虫交织在一起的社会生态动态以多次重新构建和重新发现为标志。因此，对法国“金合欢”景观的地理历史关注为了解西欧过去和正在进行的区域森林转型的政治经济提供了一个原始窗口。
