Such a thick, tropic-like vegetation one doesn't expect in Siberia. Nearly one third of the entire area of Kamchatka is covered by the birch forests. The loosely standing trees allow a lot of light falling at the forest ground. The good light conditions make possible, that huge, grassy plants grow on the forest ground. The thick and tall herbs give the forest a touch of tropical jungle. The three meter high stems of the giant herbs hide a man easily. Inside the thickets the plants make you step by touch: no direction seen, the sun and skies are hidden by the broad leaves, and willy-nilly you are pleased with bears' paths cleaving the wall of stems like tunnels. Despite of their dense stand the tall herbs are friendly plants: leaves are soft, stems are easy to be moved apart with hands or a stick. The birch trees are very good suited to withstand the tons of snowfall falling in the Kamchatkas' winter: the thick and short stems and the thick, wide spreading branches can carry big amounts of snow. Because of their loosely, almost solitaire stand the snow can fall through in the holes between the trees, relieving the birches of carrying the whole snow carpet alone.
