Saxifraga nivalis is one of the rarest plants in flora of Central Europe. One isolated relict population occurs in the Karkonosze Mts. Overexploitation caused, that the population consists of no more than 20 individuals and is critically endangered of extinction. The species is cultivated on secondary locations in Botanical Garden in Wrocław and a nursery of Karkonosze National Park in Jagniątków. The trial of population recovery was made in July 2007. 10 young plants from in vitro cultivation and 5 seedlings from the KPN nursery were introduced into rock crevices near the natural site of the species. 5 plants survived winter and started to grow in spring of 2008: 3 specimens from in vitro culture and 2 seedlings of KPN nursery. In 2009 only the plants from the nursery exist, 1 of them started to bloom; the plants from in vitro culture did not survive the second winter.
