The moss Drepanocladus lycopodioides, considered extinct in the Czech Republic, has been rediscovered. The population occurs in an abandoned sandstone quarry with a shallow water pool; the site known as Lom Rasová is located in the Bílé Karpaty Mts (the White Carpathians) in the south-eastern part of the Czech Republic. The species has not been recorded in the country since the first half of the 20th century. The plant community with D. lycopodioides recorded in the Lom Rasová quarry resembles alkaline fens transient to intermittently wet meadows, i.e. the natural habitat of the species. We conclude that abandoned waterlogged quarries mimic the key environmental conditions that determine the natural occurrence of D. lycopodioides, i.e. high calcium richness, water table fluctuations, low productivity and irregular disturbances that prevent the dominance of competitively superior species. Such conditions no longer occur in current central-European agricultural landscapes. We encourage bryologists and mire ecologists to explore abandoned quarries and other post-mining habitats with shallow water bodies, as they may represent potential refugia for endangered fen species.

已经发现了在捷克共和国已灭绝的青苔Drepanocladus lycopodioides。种群分布在一个废弃的砂岩采石场中，水池浅水。这个名为LomRasová的遗址位于捷克共和国东南部的BíléKarpaty山（白喀尔巴阡山脉）。自20世纪上半叶以来，该国尚未记录该物种。在LomRasová采石场记录的带有D. lycopodioides的植物群落类似于碱性芬斯过渡到间歇性湿润的草地，即该物种的自然栖息地。我们得出的结论是，废弃的浸水采石场模仿了决定D. lycopodioides天然发生的关键环境条件即高钙含量，地下水位波动，生产力低下和不规则干扰，从而阻碍了竞争优势物种的优势。在当前的中欧农业景观中不再出现这种情况。我们鼓励泥石学家和泥潭生态学家探索废弃的采石场和其他浅水体采后生境，因为它们可能代表濒临灭绝的物种的潜在避难所。
