Abstract
The investigation of three streams in the Moravian part of the Javorníky Mts in 2003 and 2006–2009 brings the first records of Plecoptera in these mountains. A total of 28 species and were found (30 % of the recent fauna of the Czech Republic), among which species of the upper parts of streams predominate. This result corresponds to the nature of the habitat on which researches have been carried out. One endangered species (Leuctra cf. major), two vulnerable species (Dinocras cephalotes, Perla marginata) and one near threatened species (Leuctra quadrimaculata) were recorded. Comparing the recorded species to those of the neighbouring mountains, it can be assumed that the fauna of stoneflies of the Javorníky Mts may contain more than 40 species and can form a continuous transition between the Moravskoslezské Beskydy Mts and the Bílé Karpaty Mts (including the Vizovická vrchovina Highlands).
