American pokeweed - invasive alien species, problematic for forest regeneration.

Abstract

American pokeweed (Phytolacca americana) is a very invasive plant species. As it is heliophilous, it has found ideal conditions for its spreading in clearings, which have formed after disasters and on bark beetle hot spots in recent years. It has pronounced features of a successful invasive species; it spreads vegetatively and with seeds, distributed by birds and agricultural and forestry mechanization. The seed is long-living and germinates in soil up to 40 years. In addition, it is fire resistant. The plant grows rampant on wet soil, rich in nitrogen, on acid soil and also on sandy soil. The article gives guidelines for its restraint and suppression. Quick action reduces the cost of its removal.
