Bogs and fens

- rich fens and poor fens 
Moist natural areas such as bogs and  fens can be divided into different kinds of nature.
 
Nature types depend on the amount of calcium in the soil. The amount of calcium is of great importance to the soil's acidity and therefore affects which plants can grow in the area.
 
Plant communities in different nature areas can be very different, and some species are found only in one particular habitat. Other species are more robust and can grow in different habitats.
 
Calcium-rich fen areas are often the habitat for many plant species.  They are therefore called rich fens. Bogs without calcium have fewer plant species and are therefore called poor fens.
 
Intermediate forms between the two nature types are called transitional rich fens and transitional poor fens.
