英国和爱尔兰大西洋栎树植被中的海洋苔藓成分不仅是欧洲最丰富的苔藓植物区系，也是世界上最丰富的苔藓植物区系之一。海洋气候和树冠提供的缓冲对于维持恒定的湿度和稳定的温度至关重要，这为这种多样性提供了基础。虽然这些林地给人的最初印象是岩石和树木上覆盖着一条均匀的绿色地毯，但大多数好的林地都有200多种不同的苔藓和苔藓，其中许多都是非常特殊的微生境。在林地内，最近的冰川景观提供了许多不同方面、纹理和化学物质的裸露岩石，也有深峡谷中的动荡燃烧，这增加了湿度。这些生态位被不同的苔藓植物群落利用，其中可能包含一些在欧洲非常罕见的物种，我们对这些物种负有特殊责任。这些林地的任何管理计划都应考虑到这种微生境的多样性，监测地面植被结构的任何变化对苔藓植物种群的影响是至关重要的。
Summary The oceanic bryophyte element of the vegetation of British and Irish Atlantic oakwoods is not only the richest bryophyte flora in Europe, it is also one of the richest bryophyte floras in the world. The oceanic climate and the buffering provided by the tree canopy are critical in maintaining the constant humidity and equable temperatures which provide the basis for this diversity. Though the initial impression of these woodlands is of a homogeneous green carpet over both rocks and trees, most good woodlands will have over 200 different species of moss and liverwort, many of which are very specific as regards micro-habitat. Within the woodlands, a recently glaciated landscape gives much exposed rock of different aspect, texture and chemistry, and also turbulent burns in deep ravines which enhance the humidity. These niches are exploited by different bryophyte communities which may contain a number of species that are very rare in European terms and for which we have a special responsibility. Any management plans for these woodlands should take account of this variety of micro-habitat, and monitoring of the effects on bryophyte populations of any resulting change in the structure of ground vegetation is vital.
