<abstract xmlns="http://www.w3.org/1999/xhtml">Relations between climatic factors during the winter season (n days with frost &lt;0oC and −10oC; n days with snow cover: >1 cm, >10 cm and >30 cm; maximum snow cover during season [cm]) and mortality in free-living ungulates (red deer <italic>Cervus elaphus</italic> Linnaeus, 1758, roe deer <italic>Capreolus capreolus</italic> Linnaeus, 1758 and mouflon <italic>Ovis aries musimon</italic> Linnaeus, 1758) in the Owl Mountains (Lower Silesia – Poland) in years 1998–2010 were investigated. Significant effects of all analysed climatic factors on ungulates mortality were documented.
