虽然缅甸北方的山地森林是世界上生物多样性最丰富的地区之一，但我们对这些森林中物种丰富度和物种海拔分布的了解很少，而且在空间和时间尺度上都很分散。在过去的50年里，很少进行植物区系评估。对于蕨类植物和石松植物来说尤其如此。一个国际合作项目小组于2012年、2013年和2014年对缅甸北方和西北部的维管植物物种海拔分布进行了首次基于地块的清查。在缅甸北方和西北部的海拔梯度上，在天然或很少受到干扰的森林和高山灌丛中每隔200米取样4块400米（2）的样地。我们记录了132个样地的所有蕨类植物和石松植物，总共产生了3,978个标本。根据这些收集，我们提出了一个清单的蕨类植物和石松植物物种。共鉴定出24科72属299种。这一试点项目是对即将开展的缅甸植物群的贡献，并提供了该区域的基线数据集，以确定保护的优先事项和保护区的公告。
Although the montane forests of northern Myanmar are part of one of the most biodiverse areas of the world, our knowledge of species richness and elevational distribution of species within these forests is poor and scattered at both spatial and temporal scales. Over the last five decades, very few floristic assessments have been undertaken. This is especially true for ferns and lycophytes. An international collaborative project team undertook the first plot-based inventory of vascular plant species' elevational distribution in northern and northwestern Myanmar in 2012, 2013 and 2014. At elevational gradients in northern and north-western Myanmar, four 400 m(2) plots were sampled at intervals of 200 m in natural or little-disturbed forests and alpine thickets. We recorded all ferns and lycophytes from 132 plots, producing a total of 3,978 specimens. Based on these collections we present a list of fern and lycophyte species. A total of 299 species from 72 genera and 24 families were identified. This pilot project is a contribution to the upcoming Flora of Myanmar and provides a baseline dataset of the region to set priorities for conservation and the gazetting of protected areas.
