The pond is stocked with a number of fish species, namely:German carp, (common) carp, pike, perch, roach, bream, and grass carp (white amur). The major threats: noise and refuse dumping.

Close to the pond are: Krakus mound, the Liban quarry, a complex of ponds near Krakow-Bonarka railway station, Wzgórze Lasoty (hill) and Bonarka nature reserve. The whole area has been proposed by the Foundation for the Support of Ecological Initiatives for designation as a protected landscape-nature complex.
