Начало восстановления лесной растительности после воздействия пирокластической волны вулкана Шивелуч (Камчатка) 27 февраля 2005 г.

In the spruce forest destroyed by a powerful pyroclastic surge, willow has been reestablishing on the surge deposits. Over a decade, the willow has formed a 6–8 m high canopy. The authors have specified the following factors that contributed to such a rapid reestablishing: a favourable moisture regime of the root zone caused by the deposition of the surge, the resources of the buried soil that feed the willows, and a certain protective role of dead trees. Prospects of further succession are being discussed; the authors have concluded that over about a 50-year-long period the willow will mostly fall out; by the end of the century the spruce will have partially restored its positions, but the stand will be mixed.
