The role of different taxonomic and ecological groups of the wild animals as the eliminators of helminthes of domestic animals was considered. The participation of anural amphibian (on the example of moor frog) for the sanitation of the pastures and near-water landscapes from the helminthes of domestic and hunting animals: as the direct eliminators of non-specific parasites (including the consuming of insect and other invertebrates as intermediate hosts) and as the hosts of competitor worm species - was analyzed. Among the mature helminthes forms in the moor frog from the most landscapes of Pavlodar region 3 trematodes species Pleurogenes intermedius, Haplometra cylindracea, Opisthioglyphe ranae and 2 nematodes species - Rhabdias bufonis и Oswaldocruzia filiformis parasitized. Among the larval helminthes stages in the flood-land of Irtysh river cystacanthes of Sphaerirostris teres, metacercaria Strigea strigis, Sfalconis which are harmless for people, fishes and home animals were recorded. We can rank to the potentially dangerous parasites only larval stages of trematode A.alata which have increasing of the quantity in Pavlodar region so rarely. Brown land frogs (including moor frog) can play the noticeable role in the improvement of sanitary condition of pastures and near-water landscapes from the helminthes by several positions: 1) as the direct eliminators of larval stages of pasture parasites of home hoofed animals from suborder Strongylata and other nematodes with the simple life-cycle; 2) as the definitive hosts of harmless for the people nematodes which are the competitors of pasture parasites from suborder Strongylata; 3) as the definitive and intermediate hosts of several trematodes species which are the competitors of the trematodes of hoofed animals, aquatic birds, fishes on the stage of parthenogenetic larvae in fresh-water gastropod snails; 4) as the eliminators of larval stages of several practically important helminthes in the intermediate hosts - snails and arthropods (Eurytrema, Dicrocoelium, suborder Spirurata).
