Xerothermic biotope is a scientific term for a biotope with the meaning:
⋅ Dry and thermophilic relating to xerothermic vegetation, etc. of natural species or communities,
⋅ Soil areas with high average temperatures and very low precipitation

Typical xerothermic habitats (xerotherms) are unforested sunny rocky or meadow habitats, i.e. drier biotopes. Due to their specificity, a number of unique and rare species of plants and animals are associated with xerothermic habitats.

In Europe, or rather in the Czech Republic, xerothermic habitats are usually found most often on south-facing slopes such as rocky or sod steppes and forest-steppes. In the Czech Republic, Germany and Poland, etc., natural communities can be observed in xerotherms that have their center of occurrence in southern Europe, where for many of them this is the northern border of their distribution area. For the preservation of xerothermic organisms, agricultural terraces, or rather their slopes, are also gaining ecological importance as a refugium for these organisms.
