Most of the peat bog is drained by the Kvildský brook into the Teplá Vltava, a smaller part by the tributary of the Hamerský brook into Otava, so it is a plateau peat bog. Now the area is in the first zone of the National Park and is therefore the most strictly protected. The average depth of peat in this moor is 2.5 m, the greatest thickness is 7.6 m.

The high groundwater level allows the development of typical peatland vegetation. In the dry part, it is mainly kale cypress, Scots pine, dwarf birch, frost form of spruce and heather. The most important plant in the upland is peat bog. A plant with an incredible ability to absorb water – it can increase its weight up to 25 times. The plant carries its own water reservoir. Upwards, the peat bog grows, the lower layers die and settle, thus creating peat. Vegetation co-creates the environment for the life of rare animals, especially insects. Many animals are directly attached to the peat bog.

Due to the high altitude, there are low temperatures throughout the year and thanks to low water evaporation, rainwater collects here. . It is interesting that during the last 35 years of measurement, the sub-zero temperature was measured here at least once every month. So even in summer it freezes here!
