The fauna of the reserve is very rich due to the diversity of forest and wetland habitats. The channel starts in a swamp, stretches along a dirt road and ends in a small pond 2×2 m. Fir trees (Picea abies), birch trees (Betula sp.) and willow bushes (Salix viminalis) grow along its banks. The depth of the channel is from 25 cm to 0.6 m (depth of the pond).
