Reaktion von Stachys alopecuros (L.) Bentham auf Entfernen der Nachbarn: Präzisionsmana- gement gefährdeter Arten in Graslandbrachen

Abstract

A neighbor-removal experiment was carried out in an abandoned grassland dominated by Molinia arundinacea with the low abundant perennial Stachys alopecuros (L.) Bentham as a target species. With neighbors removed S. alopecuros produced more ramets and leaves resulting in increased total leaf area per individual plant although leaves were smaller and had shorter petiols compared to control individuals within the intact vegetation. Treatment and design as demonstrated in this experiment with S. alopecuros are recommended for further controlled actions to reinforce endangered populations of rare species in abandoned grasslands.
