The terms with concern to the small relief (the continuous small height differences in mires) are explained by Sjörs (1950). They include features like hummocks and strings, hollows  and  flarks,  pools  and  soaks.  lawn,  carpet,  mire  margin,  mire  expanse, intermediate level, flark level.

The terms swamp/spring influence are explained in Eurola en Kaakinen (1984). The mire types are explained in Moen (1984).

An increase of the trophic status implies an increase of the pH and/or nutrient content. The trophic status is expressed in the following terms. In increasing order:


  The Andmyran is a complex of several types of mire: plain bogs, atlantic raised bogs with  excentric  features,  sloping  fens  and  flark  fens.  The  largest  part  consists  of oligotrophic mires (plain bogs and sloping fens). Smaller parts are minerotrophic. These parts  are  fed  by  streams  and  seepage  coming  from  the  surrounding  mountains  or mineral‑rich hills, or they are wide and big soaks in the distal parts of oligotrophic mires. Some of these minerotrophic mires have some characteristics of a string mire; big wet surfaces (flark pools) separated by narrow band‑like  hummocks  (strings).  Many samples have been token in this mire type. The different mire types of the Andmyran are separated by watertracks of various types.
