采用被动管理的恢复技术依赖于开垦后的自然植物群落演替，使受干扰地区恢复到原始生态系统。这一方法经常用于受采矿活动影响的地区，但效果不一，取决于本地植物在高度退化土壤中生长并战胜入侵物种的能力。我们评估了三个前露天矿的活动暴露了碱性冰碛物母质的恢复进展。矿山进行了复垦（分级，土壤压实和种植快速生长的草本植物），然后进行了7年，28年和35年的被动管理。在20世纪80年代最初的恢复规划时，当地的木本物种预计将在10-20年内使该遗址成为森林。将这些地点视为时间序列，我们观察到在这35年的时间跨度内，木本植被的增加不一致。目前大多数木本植物是入侵物种（胡颓子和鼠李），对恢复原生林起反作用。然而，结果并不完全是负面的，增加整体本地物种和减少外来物种在老网站，植物群落组成的变化有点一致，随着时间的推移。这表明演替已经放缓，而不是完全停止，本地草本植物正在建立。恢复工作的进展似乎远远慢于最初规划时的预期。此外，本土木本植物很难建立，而入侵木本植物却在蓬勃发展，这引发了人们的怀疑，即被动管理的继承能否在这个严重退化的栖息地中实现本土物种森林的预期结果。
Restoration techniques using passive management rely on natural plant community succession after reclamation to return disturbed areas to native ecosystems. This approach is often used in areas affected by mining activity, but effectiveness is variable and depends on the ability of native plants to establish in highly degraded soil and outcompete invasive species. We evaluated the restoration progress of three former surface mines where activity had exposed alkaline glacial till parent material. The mines underwent reclamation (grading, soil compaction, and planting fast‐growing herbaceous species) followed by passive management for 7, 28, and 35 years. At the time of initial restoration planning in the 1980s, native woody species were expected to recolonize the site within 10–20 years. Treating the sites as a chronosequence, we observed that woody vegetation increased inconsistently over this 35‐year timespan. Most of the woody plants present today are invasive species (Elaeagnus umbellataandRhamnus frangula) that are counterproductive to reestablishment of native forest. However, results were not entirely negative, with increased overall native species and decreased exotic species in the older sites, and plant community composition changing somewhat consistently over time. This suggests that succession has been slowed rather than completely arrested, and native herbaceous plants are establishing. The progression of restoration appears to be far slower than expectations during initial planning. Furthermore, native woody plants struggle to establish, whereas invasive woody plants are thriving, raising doubts that passively managed succession can lead to the desired outcome of a native species forest in this significantly degraded habitat.
