In an agricultural landscape small midfield ponds fulfill biocenotic and physiocenotic functions. A variety of species settle in areas of midfield ponds. The aim of our studies was to determine whether the occurrence of aquatic and marsh species in the studied bodies of water is a random effect or a result of spatial autocorrelation. On the basis of conclusions from ESDA, the hypothesis of spatial randomness can be rejected, which opens the way for searching spatial regimes. The review analysis of the spatial data (ESDA) with the use of join-count statistics showed that there is a positive spatial correlation for the midfield ponds in the agricultural area of the Pyrzyce-Stargard Plain in the distribution of ten aquatic and rush species for a distance of 1,250 m. The results of statistical analysis (ESDA) can constitute the basis for the choice and protection of midfield ponds as stop islands fulfilling functions of "mini" ecological corridors in spreading plant species.
