Chat Moss along with Risley Moss and Holcroft Moss, is also a European Union designated Special Area of Conservation, known as Manchester Mosses. The major habitats in the moss are bog, heathland, woodland and acidic grassland, subject to varying degrees of wetness depending on the local drainage. The remaining areas of bog are dominated by common cottongrass "Eriophorum angustifolium" and hare's-tail cottongrass "E. vaginatum". Bog mosses are more scarce, but "Sphagnum cuspidatum", "S. recurvum", "S. tenellum", "S. fimbriatum" and "S. subnitens" occur in patches. As the peat has become drier, areas have been taken over by purple moor grass "Molinia caerulea" and
Moss teeth called peristome. This may be absent in some mosses. Most mosses rely on the wind to disperse the spores. In the genus "Sphagnum" the spores are projected about off the ground by compressed air contained in the capsules; the spores are accelerated to about 36,000 times the earth's gravitational acceleration "g". It has recently been found that microarthropods, such as springtails and mites, can effect moss fertilization and that this process is mediated by moss-emitted scents. Male and female fire moss, for example emit different and complex volatile organic scents. Female plants emit more compounds than male plants. Springtails
