The importance of moss biodiversity conservation in Iran

The mosses, despite their primitive structure, are of great importance and constitute a large part of forest biodiversity, having different functional roles due to their ecological position and particular life forms. In terms of moss flora, Iran's ranking is the second place among the countries of the Middle East. The problems associated with plant identification have led to less awareness of their importance in ecosystems, while the sustainability of ecosystems depends on the presence of these plants and their biodiversity. According to the conservation status of mosses flora in Iran and also relying on the introduction of some endemic, rare and endangered species, the values of various statistical species diversity methods were emphasized to evaluate the species status. In this way, while introducing this group of influential plants, it is possible to preserve the composition and structure of natural forests in natural resources management programs as well.
