Mosses, lichens and dwarf trees, characteristic plants of the Arctic lands.
The stony outcrops of the rocks are covered with perennial grasses, shrubs blooming from spring to autumn, mosses, lichens and dwarf trees typical of tundra. Here grow Siberian dwarf pine, Arctic bramble and willows of the Arctic group. The predominance of low plants makes it possible to preserve the view of the historical development of Varvarka.
The most important factor of tundra existence in nature is permafrost. Under natural conditions of a short polar summer, organic substances do not have time to decompose completely, so the soil nutrients and nitrogen content is very low. This limits the intensity of plants growth. The vegetation period of tundra plants is very short compared to the vegetation period of plants in Central Russia. Since creating permafrost in Moscow without energy costs is impossible due to the weather conditions, the park provides engineering solutions that imitate it. A water-resistant underground layer of clay, for example, supports stagnant water. Fogging plants humidify the air. The stony interlayer allows draining the topsoil so that the roots feed on moisture and the plants develop well.
