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.
