The reserve features diverse habitats, including woodlands, meadows, and wetlands, providing a sanctuary for various wildlife species. Notable trees such as black poplars and a variety of birds, including woodpeckers, kingfishers, and grebes, inhabit the area. The ponds within the reserve support wetland plants and serve as crucial habitats for amphibians and insects.
