Abstract

Although the České středohoří PLA is one of the most malacologically explored areas in Central Europe, ongoing research shows that there are still previously unexplored places with rich malacofauna. The Houžetín Hill near the village of Skalice hosts extremely rich flora and its research has also shown relatively rich mollusc fauna (45 species). Unexpectedly, many strictly forest species were found there in 2019, such as Discus perspectivus, Isognomostoma isognomostomos, Aegopinella nitidula and many others. It is unusual for this part of the PLA and it proves that the forest environment has been maintained there continuously for a long time, probably since the forest climatic optimum of the Holocene.

Highlights

  • O tom, že lze i v tak přírodovědecky probádaném území jakým je CHKO České středohoří, ještě dnes nalézat dosud nepříliš známé plochy s překvapivým druhovým bohatstvím, vypovídá právě území zkoumaného vrchu Houžetín

  • Že tak geomorfologicky rozmanité a botanicky zajímavé území, jakým je vrch Houžetín, zůstávalo doposud malakologicky neprozkoumáno a unikalo tak dlouho pozornosti i přes stopadesátiletou tradici v průzkumu středohorských měkkýšů

  • In sparse forests on the eastern slope of Houžetín Hill, fossil calcareous tufa can be found, forming cascades that are visible at first sight
