Species presently considered as invasive were often deliberately introduced. Which factors led them from being desired to being denounced and what trajectory did such a transition follow? Using the case of common gorse (Ulex europaeus) on Reunion Island, the aims of this study were first, to identify and describe the different status that were attributed to this species since its introduction; and second, to discern the factors that influenced their emergence and decline in the public sphere. Five types of status were identified for common gorse in Reunion (useful, nationalistic, indigenized, noxious weed, and invasive), each peaking at a certain time, and then reverting to a low-key presence. The emergence and dissemination of each status in the public sphere depends on how well the various narratives proposed about the plant by networks of legitimate actors match the socio-technical landscape, as well as on how these narratives appear within legal and institutional frameworks. In addition, translating a status into actions of management can bolster its trajectory in the public sphere. Lastly, the decline of a status can be explained by a gradual desynchronization between its cognitive, normative and/or instrumental dimensions and the local socio-technical landscape.
目前被认为是入侵物种的物种通常是被有意引入的。是什么因素导致它们从被追捧到被谴责，这种转变遵循了什么轨迹？本研究以留尼汪岛的普通金雀花（Ulex europaeus）为例，首先，确定并描述自引入以来该物种所经历的不同地位；其次，识别影响其在公共领域出现和衰落的因素。在留尼汪岛，普通金雀花被确定有五种地位（有用、民族主义、本土化、有害杂草和入侵），每种地位都在特定时期达到高峰，然后又回归低调。每种地位在公共领域的出现和传播都取决于合法行为者网络提出的关于植物的各种叙述与社会技术景观的吻合程度，以及这些叙述在法律和制度框架内的表现方式。此外，将一种地位转化为管理行动可以增强其在公共领域的轨迹。最后，地位的衰落可以解释为其认知、规范和/或工具维度与当地社会技术景观之间逐渐失去同步。
