Total dataset of Estimating moss harvest quantity and biomass

The legal harvesting of moss in Turkey from designated areas is permitted; however, the absence of comprehensive inventory studies in these harvested zones poses a considerable threat to moss species. Harvesting without proper inventories can negatively impact rare, sensitive, and even endemic species in the region. Furthermore, there is a significant lack of research regarding the sustainable quantity of moss that can be harvested per hectare in forested areas. This study, conducted on Eldivan Mountain over an area of 4,200 hectares, aimed to address the significant gap in moss inventory and sustainable harvesting practices. Sampling was conducted every 300 meters, measuring mosses in 4 m² ground plots and 50 m² tree plots. The total area covered by the identified moss taxa was approximately 97,216,557 m², with a total dry weight of 44,640,972 kilograms. The most widespread ground species, Syntrichia ruralis, covered 64,772,801 m² with a dry weight of 623,268 kilograms, while the dominant tree species, Hypnum cupressiforme var. lacunosum, covered 3,937,266 m² with a dry weight of 1,448,533 kilograms. In conclusion, due to insufficient rainfall for the growth of epiphytic moss species in Turkey, harvesting moss from trees is not sustainable. Moreover, it is recommended that sustainable moss harvesting be limited to 1-1.5 tons per hectare on the ground.土耳其允许从指定区域合法采收苔藓，但此类采收区域尚未开展全面的苔藓清查研究，这对当地苔藓物种构成了显著威胁。未开展合规清查的采收行为，会对该区域的稀有、敏感乃至特有苔藓物种造成负面影响。此外，针对林地内每公顷可可持续采收的苔藓量，目前仍存在显著的研究空白。本研究在埃尔迪万山（Eldivan Mountain）的4200公顷区域内开展，旨在填补苔藓清查与可持续采收实践方面的研究空白。研究以每300米为间隔设置采样点，在4平方米的地面样方与50平方米的树干样方中对苔藓进行调查测定。经鉴定的苔藓类群总覆盖面积约为97216557平方米，总干重为44640972千克。分布最广的地面生苔藓物种为泛生墙藓（Syntrichia ruralis），其覆盖面积达64772801平方米，干重为623268千克；而优势树干附生苔藓物种为细枝羽藓（Hypnum cupressiforme var. lacunosum），覆盖面积为3937266平方米，干重为1448533千克。综上，由于土耳其的降雨量不足以支撑附生苔藓物种的生长，从树干采收苔藓的行为不具备可持续性。此外，建议地面生苔藓的可持续采收量应控制在每公顷1至1.5吨。
