Mustansaarenkeidas is a raised bog. This is evident in the beginning of the duckboard trail, where the trail rises over two meters when entering the bog. All the water and nutrients on the raised bogs come from rainwater; no water flows into them from surrounding mineral lands. Because of this, the vegetation on raised bogs is very rugged.
