Molluscs of the Uplaz Nature Reserve (Moravian-Silesian Beskydy Mts., Czechia)

Jiří Kupka & Lukáš Kupka

The malacofauna of the Uplaz Nature Reserve (Moravian-Silesian Beskydy Mts., Czechia) was studied in 2018. Altogether, 56 mollusc species were recorded from 119 sampling sites, including 53 terrestrial gastropods, 2 freshwater gastropods, and one freshwater bivalve species. The most species-rich part was Uplaz I, with up to 35 species recorded at a single sampling site. Several species of conservation concern were recorded, including two critically endangered species (Macrogastra borealis, Vestia gulo), one endangered species, and three vulnerable species. The study area, together with adjacent reserves (Mionší NNR and Velký Polom NR), represents an important component of a forest malacofauna refugial complex in the Beskydy Mountains. The results suggest the importance of natural forest structure, spring habitats, and coarse woody debris for maintaining high mollusc diversity.
