Seed characteristics play an important role in the colonization and subsequent persistence of species during succession in disturbed sites and thus may contribute to being able to predict restoration success. In the present study, we investigated how various seed characteristics participated in 11 spontaneous successional series running in different mining sites (spoil heaps, extracted sand and sand-gravel pits, extracted peatlands, and stone quarries) in the Czech Republic, Central Europe. Using 1864 samples from 1- to 100-years-old successional stages, we tested whether species optimum along the succession gradient could be predicted using 10 basic species traits connected with diaspores and dispersal. Seed longevity, diaspore mass, endozoochory, and autochory appeared to be the best predictors. The results indicate that seed characteristics can predict to a certain degree spontaneous vegetation succession, i.e., passive restoration, in the mining sites. A screening of species available in the given landscape (regional and local species pools) may help to identify those species which would potentially colonize the disturbed sites. Extensive databases of species traits, nowadays available for the Central European flora, enable such screening.
种子特性在受干扰地点的演替过程中对物种的定殖和随后的持续存在起着重要作用，因此可能有助于预测恢复的成功。本研究调查了各种种子特性如何参与了在捷克共和国（中欧）的不同采矿地点（废石堆、开采的沙石坑、开采的泥炭地和采石场）中运行的 11 个自然演替系列。使用来自 1 到 100 年演替阶段的 1864 个样本，我们测试了使用与胚珠和散布有关的 10 个基本物种特征是否可以预测物种在演替梯度上的最佳状态。种子寿命、胚珠质量、内生动物传播和自体传播似乎是最好的预测因子。结果表明，种子特性可以在一定程度上预测采矿地点的自然植被演替，即被动恢复。对给定景观中可用物种（区域和地方物种库）的筛选可能有助于识别那些有可能在受干扰地点定殖的物种。目前，针对中欧植物群的广泛物种特征数据库使这种筛选成为可能。
