Oxytropis uramovii Jav. is a local endemic to the marble part of North Pirin Mts. Oxytropis kozhuharovii Pavlova, Dimitrov and Nikolova has even more restricted distribution in Pirin Mts. Both plant species reproduce by seed and have poor vegetative propagation. There is no direct human threat to these plants at the moment except hiking, but they are well localised in the wild. Due to active ski-resort development in Pirin Mts. their conservation becomes a matter of some urgency. In this study we tested the seed germination process, development of the seedlings and ex-situ seedling behaviour. Most mature test seeds would germinate within a couple of days if the seed coat was scarified. The seedlings were rather sensitive and many did not survive 7 the possible reasons were discussed. The seedlings of the tetraploid O. kozhuharovii developed slightly better than those of the diploid O. urumovii and during the second year after germination several seedlings bloomed.
