Reintroducing lichens and mosses to areas slated for restoration or rehabilitation may prove integral to project success by filling the biocrust component (niche) of arid ecosystems. In doing so, it is important to select appropriate species and genetic source material. Some bryophyte and lichen species are early pioneers and are potentially well‐suited for restoration projects. Species traits such as high reproductive rates, rapid establishment rates, and large asexual reproductive propagules can be beneficial for restoration. For instance, the large number of spores produced by some mosses are beneficial for reproductive success in arid environments. In addition to identifying the benefit of reproductive strategies, it is important to take habitat needs into consideration; lichen and moss species that are wide‐ranging both geographically and ecologically are recommended over geographically and edaphically restricted species that occur only in specific habitats, such as calcareous soils. Biocrusts used in specific restoration areas should have similar genetic source material (local provenance), and harsh environmental conditions should be ameliorated.

最适合修复项目的生物地衣和苔藓物种

通过填补干旱生态系统的生物外壳成分（生态位），将苔藓和苔藓重新引入计划恢复或恢复的地区可能证明对项目成功至关重要。在此过程中，重要的是选择合适的物种和遗传资源。一些苔藓植物和地衣物种是早期的开拓者，可能非常适合进行修复项目。诸如高繁殖率，快速建立率和大型无性生殖繁殖体等物种性状可能对恢复有益。例如，一些苔藓产生的大量孢子有利于在干旱环境中繁殖。除了确定生殖策略的好处外，还必须考虑到栖息地的需求；建议在地理和生态上受限制的物种（仅在特定的生境，如石灰性土壤中发生），在地理和生态上广泛分布的地衣和苔藓物种。在特定恢复区域中使用的生物外壳应具有相似的遗传来源材料（当地来源），并且应改善恶劣的环境条件。
