Sažetak

Campanula tommasiniana is a narrow endemic of Mt Učka occupying 6-7 km2 between 50-1396 m a.s.l. within its distribution range, five more or less homogenously inhabited micro-sites were identified. The majority of the population occupies rock crevices of boulders, cliffs and rocky outcrops above 900 m a.s.l., within the zonal thermophytic and altimontane and subalpine beech forests, although specimens were frequently recorded in various secondary habitats across its distribution range. Due to the lack of data on species biology, density, genetic population structure and potential gene flow within and among microsites it is difficult to estimate the extent of particular threats to the species. nevertheless, destruction of already occupied and potential habitats may represent a real threat for the long-term survival of this narrow endemic with pronouncedly patchy distribution. hence, every established and potential growth site, especially rocky outcrops and cliffs should be strictly preserved.
