传统上，山区牧场的养护和管理完全是根据可见的生物区系进行的。然而，微生物对土壤生态系统的功能发挥着至关重要的作用，因此，牧场的可持续性。在这里，我们研究了土壤微生物（地下）群落结构（使用原核生物和真菌的扩增子测序），其他土壤理化和生物学特性，最后，各种牧场管理措施之间的联系。为了这个目标，在连续两年，我们研究了104个环境站点，其特点是对比海拔，栖息地，基岩和牧场管理;位于戈尔贝亚自然公园（巴斯克地区/西班牙）或附近。土壤pH值是影响土壤微生物多样性的重要因素之一。有趣的是，我们观察到原核生物，真菌和大型动物多样性之间的惊人相关性，可能是由这些生命形式之间的相互作用引起的。需要进一步的研究，以更好地了解这种相互作用，并针对不同的管理措施对土壤微生物群落的影响，在面对显着的异质性。然而，清除灌木改变了微生物群落结构，在石灰岩基岩的地点也使用除草剂与机械清除蕨类植物。
Traditionally, conservation and management of mountain pastures has been managed solely on the basis of visible biota. However, microorganisms play a vital role for the functioning of the soil ecosystem and, hence, pasture sustainability. Here, we studied the links between soil microbial (belowground) community structure (using amplicon sequencing of prokaryotes and fungi), other soil physicochemical and biological properties and, finally, a variety of pasture management practices. To this aim, during two consecutive years, we studied 104 environmental sites characterized by contrasting elevation, habitats, bedrock, and pasture management; located in or near Gorbeia Natural Park (Basque Country/Spain). Soil pH was found to be one of the most important factors in structuring soil microbial diversity. Interestingly, we observed a striking correlation between prokaryotic, fungal and macrofauna diversity, likely caused by interactions between these life forms. Further studies are needed to better understand such interactions and target the influence of different management practices on the soil microbial community, in face of the significant heterogeneity present. However, clearing of bushes altered microbial community structure, and in sites with calcareous bedrock also the use of herbicide vs. mechanical clearing of ferns.
