According to a study done in the Czech Republic , the mean hare densities were highest at altitudes below 200 metres ( 660 ft ) , 40 to 60 days of annual snow cover , 450 to 700 millimetres ( 18 to 28 in ) of annual precipitation , and a mean annual air temperature of around 10 ° C ( 50 ° F ) . With regards to climate the study found that hare densities were highest in : " A warm and dry district with mild winter and longer duration of sunshine ; a warm and dry district with mild winter and shorter duration of sunshine ; a warm and moderately dry district with mild winter " .
