Występowanie kokoryczy drobnej Corydalis pumila na Pomorzu Zachodnim

Abstract

Corydalis pumila is a species rarely observed in Poland, only in north-west part of the land. It was known only from 11 localities in 2001 and in the Polish Red Data Book of Plants the species was recognized as vulnerable in the country. The paper presents 20 new localities of Corydalis pumila in Western Pomerania. The species has very rich populations in the Parsęta river basin. It was observed also on new locality on the Krąpiel river. Survival of the species is dependent on preservation of natural or semi-natural oak-hornbeam forests on the slopes of the valleys. Prospects of such habitat in Western Pomerania may be pretty good thanks to Natura 2000 network.
