Introduction history, including propagule pressure and residence time, has been proposed as a primary driver of biological invasions. However, it is unclear whether introduction history increases the likelihood that a species will be invasive or only the likelihood that it will be established. Using a dataset of non‐native species historically available as ornamental plants in the conterminous United States, we investigated how introduction history relates to these stages of invasion. Introduction history was highly significant and a strong predictor of establishment, but only marginally significant and a poor predictor of invasive success. Propagule pressure predicted establishment better than residence time, with species likely to be established if they were introduced to only eight locations. These findings suggest that ongoing plant introductions will lead to widespread establishment but may not directly increase invasive success. Instead, other characteristics, like plant traits and local scale processes, may better predict whether a species becomes invasive.

来自美国历史性植物销售的繁殖压力解释了建立而不是入侵

引入历史，包括繁殖体压力和停留时间，已被认为是生物入侵的主要驱动因素。然而，目前尚不清楚引入历史是否增加了物种入侵的可能性，还是仅增加了该物种定居的可能性。我们使用美国本土历史上可用作观赏植物的非本地物种的数据集，研究了引入历史与这些入侵阶段的关系。引入历史非常重要，并且是建立的强有力的预测因素，但只有轻微的意义，并且对侵入成功的预测作用很差。繁殖体压力比停留时间更能预测定殖，如果物种仅被引入八个地点，则它们可能会定殖。这些发现表明，持续的植物引进将导致广泛的定居，但可能不会直接增加入侵的成功率。相反，其他特征，如植物性状和局部尺度过程，可以更好地预测一个物种是否具有入侵性。
