Most ferns occur in moist and shaded environments; their relatively narrow band of survival conditions increase their extinction risk under Anthropocene-linked climate change. (L.) C. Presl is a perennial fern that has a natural distribution primarily encompassing the East Asian mountains. In this study, we characterized the vegetation and environmental factors in low- and high-elevation mountain ranges and montane wetlands to elucidate the optimal habitat for . We found that populations of developed better in high-elevation mountains than in low-elevation mountains. However, the low light intensity in high mountain forests reduces opportunities for reproduction. The montane wetlands recorded the highest biomass among the three habitat types, and the investment in reproduction was also significantly higher. The montane wetlands also showed higher light intensity, substrate fertility, and water content. Overall, the montane wetlands were found to be the optimal habitat for . At lower elevations, lower precipitation, higher temperatures, human disturbance, and low substrate water could be factors limiting the expansion of this fern's distribution. Our study points to the importance of conserving montane wetlands to prevent the extinction of ferns.
大多数蕨类植物生长在潮湿和阴凉的环境中；它们相对狭窄的生存条件范围增加了在与人类世相关的气候变化下的灭绝风险。(L.) C. Presl是一种多年生蕨类植物，其自然分布主要涵盖东亚山区。在本研究中，我们对低海拔和高海拔山脉以及山地湿地的植被和环境因素进行了特征描述，以阐明(L.) C. Presl的最佳栖息地。我们发现，(L.) C. Presl的种群在高海拔山脉中比在低海拔山脉中生长得更好。然而，高山森林中较低的光照强度减少了繁殖机会。山地湿地在三种栖息地类型中生物量最高，繁殖投入也显著更高。山地湿地的光照强度、底物肥力和含水量也更高。总体而言，山地湿地被发现是(L.) C. Presl的最佳栖息地。在较低海拔地区，降水量较低、温度较高、人为干扰以及底物含水量低可能是限制这种蕨类植物分布范围扩大的因素。我们的研究指出了保护山地湿地以防止蕨类植物灭绝的重要性。
