Why do stones grow moss and buds?

Bryophytes like dark and humid environment, and generally grow on bare stone walls or wet forests and swamps. Moss is not suitable for growing in the shade. It needs some scattered light or semi-cloudy environment. The most important thing is that it likes humid environment, especially it is not resistant to drought and dryness.

In addition, the temperature below 22℃ slows down the growth, and it grows well above 25℃. Moss is spongy and absorbs water on the stone surface for a long time, which will make the stone under it wet for a long time and lead to deterioration and discoloration.

distribution range

Bryophytes are widely distributed and can live in tropical, temperate and cold regions (such as Antarctica and Greenland). The patches of bryophytes are called tundra, which are mainly distributed in northern Eurasia and northern North America, and locally grow in alpine areas above the tree line.

Bryophytes that can prevent soil erosion generally grow densely and have strong water absorption, which can hold the soil tightly and help to maintain water and soil. It can be used as food for birds and mammals to help form soil. Bryophytes can accumulate moisture and floating dust in the surrounding environment, secrete acidic metabolites to corrode rocks, promote rock decomposition and form soil.
