The arachnological research was carried out in the year 2010 on the southern slopes and forest steppe of the Chlum Nature Park near the Sýcina village. The spiders were
collected mainly into pitfall traps. Three diferent types of habitats were selected. The first was a meadow, the second was site already overgrown by shrubs and the third was oak
forest. In the period from April to November in the year 2010, a total of 916 specimens of spiders were collected. They belong to 72 species in 20 families. The effect of changes in
habitat structure on the structure of spider communities was compared. The research confirmed the significance and high natural value of this locality. It is apparent that the
change of the structure of habitat has influence on the structure of spider communities.
