Flagship species of the Pieniny NP. protected ex situ at PAS BGCBDC seed bank at WARSAW-POWSIN

subject

description

Pieniny Mts. are important biodiversity hotspot in Central Europe. According to Pieniny National Park Long Term Conservation Plan 2000-2020 small, isolated populations of some of Pieniny NP flagship species can become extinct till 2020. That is why their ex situ preservation at seed bank is justified and reasonable as supplement of active and passive in situ conservation measures carried out by National Park staff. PAS Botanical Garden – Center for Biological Diversity Conservation at Warsaw-Powsin has a long tradition of cooperation with Pieniny National Park (S Poland). This article focuses on the actions undertaken during EU funded conservation project: “Ex situ conservation of native, threatened and protected plant species in eastern Poland - FlorNaturOB”. Seeds of Dendranthema zawadzkii, Erysimum pieninicum and Minuartia setacea collected by „FlorNaturOB” team at Pieniny NP: (1) showed orthodox behaviour (could be easily dried and frozen at ultra-low temperatures of liquid Nitrogen), (2) do not exhibit seed dormancy. Species’ localization and collecting time influenced the seed samples quality
