Changes in climate, land-use and pollution are having disproportionate impacts on ecosystems and biodiversity of arctic and mountain ecosystems. While these impacts are well-documented for many areas of the Arctic and alpine regions, some isolated and inaccessible mountain areas are poorly studied. Furthermore, even in well-studied regions, assessments of biodiversity and species responses to environmental change are biased towards vascular plants and cryptogams, particularly bryophytes are far less represented. This paper aims to document the environments of the remote and inaccessible Altai-Sayan mountain mires and particularly their bryofloras where threatened species exist and species new to the regional flora are still being found. As these mountain mires are relatively inaccessible, changes in drivers of change and their ecosystem and biodiversity impacts have not been monitored. However, the remoteness of the mires has so far protected them and their species. In this study, we describe the mires, their bryophyte species and the expected impacts of environmental stressors to bring attention to the urgency of documenting change and conserving these pristine ecosystems.

气候、土地利用和污染的变化对北极和山区生态系统的生态系统和生物多样性产生了不成比例的影响。虽然北极和高山地区的许多地区的这些影响都有详细记录，但对一些偏远和交通不便的山区的研究却很少。此外，即使在经过充分研究的地区，对生物多样性和物种对环境变化的反应的评估也偏向于维管植物和隐花植物，特别是苔藓植物的代表性要少得多。本文旨在记录偏远且交通不便的阿尔泰-萨延山泥沼的环境，特别是其中存在受威胁物种和仍在发现该地区植物区系新物种的苔藓植物区系。由于这些山区泥潭相对难以进入，因此变化驱动因素的变化及其对生态系统和生物多样性的影响尚未得到监测。然而，迄今为止，泥潭的偏远保护了它们及其物种。在这项研究中，我们描述了沼泽、其苔藓植物物种以及环境压力源的预期影响，以引起人们对记录变化和保护这些原始生态系统的紧迫性的关注。
