Northern red-backed vole northern forest and shrubland habitats. They occur in every major forest type in central Alaska. Plant species commonly found in areas occupied by northern red-backed voles include black spruce ("Picea mariana"), white spruce ("P. glauca"), quaking aspen ("Populus tremuloides"), paper birch ("Betula papyrifera"), alder ("Alnus" spp.), willow ("Salix" spp.), mountain cranberry ("Vaccinium vitis-idaea"), blueberry and bilberry ("Vaccinium" spp.), bunchberry ("Cornus canadensis"), and a variety of grasses and forbs. Important fungi, mosses and lichens include truffle ("Endogone fascilulata"), Schreber's moss ("Pleurozium schreberi"), mountain fern moss ("Hylocomium splendens"), sphagnum ("Sphagnum" spp.), and lichens ("Cladonia and Peltigera" spp.).

Geochemistry of carbon requirements, but unless the sea level is rising will not have a chance to accumulate much. Coral reefs are very productive, but are well oxygenated, and recycle everything before it is buried. In dead "Sphagnum", sphagnan a polysaccharide with D-lyxo-5-hexosulouronic acid is a major remaining substance. It make the bog very acidic, so that bacteria cannot grow. Not only that, the plant ensures there is no available nitrogen. Holocellulose also absorbs any digestive enzymes around. Together this leads to major accumulation of peat under sphagnum bogs. Earth's mantle is a significant reservoir of carbon. The mantle contains more carbon than
