Distribution of the European ground squirrel (Spermophilus citellus) in the Czech Republic in 2002-2008
Abstract
In 2002-2008, occurrence of the European ground squirrel was recorded at or reported from 45 sites in the Czech Republic. However, only 35 sites were verified to host ground squirrel colonies in 2008.
Most of the colonies (91%) were found in some kind of artificial habitat with high anthropogenic influence. Only (9%) of the European ground squirrel colonies occurred in natural steppe habitats.
Although three sites (9%) were recorded at altitudes above 550 m, majority of the sites (60%) were situated below 300 m a. s. l. In most (54%) of the colonies, the estimated abundance was 50 individuals or less.
Only one third of the colonies hosted 100 individuals or more. Considering the fact that 7 sites were abandoned in the period 2002-2008, it can be concluded that the decline of the European ground squirrel in the Czech Republic continues.
