The main threats of the natural populations in Bulgaria were identified. Background information conceming chorolagy, ecology and resources of the species were summarized. In situ conservation approaches were discussed: including the populati on sialus in prolecled areas, recommendalions for their management and sustainable use ofthe resources. The experience in ex situ conservation of L. aestivum was summarized. Application of biotechnological methods as well as in vivo rapid propagation via twin-scaling method were assessed and envisaged to be developed as an alternative of natural population use. Current status of 17 galanthamine-type populations localized in Southeast Bulgaria was described. Bulbs and seeds were gathcred as a germplasm for ex situ conservation.
