An oasis as a place of growth

In terms of nutrients, the bog is both rich and poor at the same time. Due to the strong growth of peat, the nutrient cycle of Keidassuo is completely separated from the nutrient resources of the mineral soil.

The center of Keidassuo receives nutrients only from rainwater and the peat of the growing medium.

Two-thirds of Hatlamminsuo's surface area belongs to these low-nutrient bog types. The modest plant species of the bog include most frogs, modest sedges, and plenty of curd and other mosses.

The edge area of ​​the swamp gets nutrients not only from rainwater and the growing medium, but also from runoff from the surrounding mineral soil, mineralotrophy prevails here.

In the middle of the Hatlammi Swamp runs a wide minerotrophic lake, which was born in the surroundings of the stream flowing through the swamp. One tenth of the minerotrophic part is medium nutrients, i.e. mesotrophic. Among the plant species exhibiting mesotrophy in Hatlamminsuo, you can find e.g. slender wool, tawny grass, woolly weevil and scurvy foot.

Nutrient-rich or eutrophic bog types do not occur in Hatlamminsuo.
