Pirttimysvuoma is a large, unexploited mire complex with several types of wetlands, vegetation and morphological structures which are important for biodiversity. The Site features open mires, tundra wetlands, forested peatlands, shrub-dominated wetlands, permanent freshwater marshes and pools, rivers and streams. The mixed palsas (frost heaves) and the surrounding fens and open waters create a landscape mosaic which harbours a rich birdlife and supports species using the Site as a foraging ground, such as the nationally red-listed ruff Philomachus pugnax, common reed bunting Emberiza schoeniclus and Lapland longspur Calcarius lapponicus. The mires and bogs play a significant role as carbon sinks. The area is frequently used for reindeer grazing: the Saami villages of Talma and Saarivuoma have the right to use the land. The management plans for the overlapping Natura 2000 site and the Nature Reserve are being implemented. Forestry activities are regulated through the nature reserve management plan, and drainage is forbidden.
