In the ranges Chełmowa Góra and Serwis-Dąbrowa of the Świętokrzyski National Park 70 species of carabid beetles (Carabidae) were reported, among them 16 species new to the fauna of the Świętokrzyskie Mountains and one, Amara littorea, very rare in Poland. The communities of the carabid beetles in both ranges had a different ecological character. It was recorded that the mechanical structure and humidity of the soils had the greatest impact on the composition and structure of the carabid communities.

In the years 1990-1991 changes in the abundance of Harpalus rufipes in one-year-old cultivated fields on four types of soils were studied in central Poland. The number of individuals caught on particular types of soil was statistically significantly different. A statistically significant relationship between the number of individuals caught and the share of mechanical fractions in soil was found as well as a statistically significant relationship between the number of H. rufipes individuals caught and the content of C, K, Mg and N and Ca in soil. No statistically significant relationship between the kind of plant cultivated and the number of H. rufipes individuals caught was found. The peak activity of H. rufipes imagines was very visible and occurred in July or August.
