In 1998 the dif­ference between the representation of the genera Apodemus and Microtus did not change considerably, and even the increase of capture rates of Crocidura species (+5%) was not that marked as in site A (Fig. 5). In this year too, both among the Apodemus species and among the entire small mammal fauna of the plot, A. agrárius was the most frequent species (with 49.68% of the total num­ber of individuals). The relative frequency of A. flavicollis was 7.76%, while that of A. syl­vaticus was 4.3%. While the proportion of species belonging to the order Rodentia was higher in both study plots, it must be noted that the ratio of Insectivora was higher in Páprád (B) than in Nagycsány (A) (Fig. 6).
