Bark of bushes contains at least in 10 larger quantity of available forms of nitrogen, than bark of trees, it has the increased value of рН, it is more than 10 times richer with phenolic substances. The less there are available forms of nitrogen and water-soluble carboniferous matters in bark, the more specific to this substratum of types of lichens there are.кора деревьев, кора кустарников, кислотность, нитраты, нитриты, аммоний, фенольные вещества, эпифитные лишайникиbark of trees, bark of bushes, pH, nitrates, nitrite, ammonium, phenol substances, epiphyte lichens
