Recent research on the organo-chemical composition of Sphagnum and on
the fate of its litter has further clarified how this plant builds aci
dic, nutrient-poor, cold and anoxic peat bogs. The bog environment hel
ps Sphagnum to outcompete other plants for light. Its morphology, anat
omy, physiology and composition make it an effective ecosystem enginee
r and at the same time benefit the plant in the short term. This may h
ave facilitated the evolution of the genus.
