Understanding the growth dynamics of spore-bearing clonal plant sporophytes and the influence of abiotic and biotic factors is crucial for predicting the persistence of club moss populations and implementing effective habitat management techniques. Despite this, the longevity and development of club-moss populations are rarely studied. This study adopted an integrated approach to assess the probability of repetitive young sporophyte recruitment via sexual propagation in L. and L. The size-age problem of clonal spore-bearing forest plants and their niche segregation were addressed. The canopy characteristics, insolation, small-scale disturbance, and genetic polymorphism were studied in temperate semi-natural Scots pine forests in Lithuania. Based on the size of the clones discovered, we hypothesize that initial sporophyte emergence occurred in 20-year-old pine stands, with subsequent sporophyte emergence continuing over time. The emergence was related to small-scale disturbances. High genetic polymorphism indicates that all sporophyte stands studied likely emerged via sexual reproduction. According to Ellenberg values, is related to shady habitats, but our findings show both species coexisting abundantly in the more open habitat, supposedly more suitable for .No significant differences in vegetation relevés and light availability was detected using hemispheric images.
了解产孢克隆植物孢子体的生长动态以及非生物和生物因素的影响，对于预测石松种群的持久性和实施有效的栖息地管理技术至关重要。尽管如此，石松种群的寿命和发育情况却很少被研究。本研究采用综合方法评估了扁枝石松和石松通过有性繁殖反复招募年轻孢子体的可能性。解决了产孢克隆森林植物的大小-年龄问题及其生态位分离。对立陶宛温带半天然苏格兰松林中的树冠特征、日照、小规模干扰和遗传多态性进行了研究。根据发现的克隆体大小，我们推测最初的孢子体出现在20年生的松树林中，随后孢子体的出现随着时间的推移持续发生。这种出现与小规模干扰有关。高遗传多态性表明，所有研究的孢子体林分可能都是通过有性繁殖出现的。根据埃伦贝格值，扁枝石松与阴暗生境有关，但我们的研究结果表明，这两个物种在更开阔的生境中大量共存，据推测这对石松更合适。使用半球图像未检测到植被记录和光照可用性的显著差异。
