The White River tributary I recorded is located in the natural scenic area of Huairou White River Bay in Beijing, about 100 kilometers from the Beijing urban area. The Scenic area has a green vegetation coverage rate of more than 90% with lush trees, fresh air, clean water quality and little polution. The climate is pleasant, with a high day and night temperature difference. The average annual temperature in the area is between 7-13 degrees Celsius, with the rainy season from June to September and the dry season from October to January.

Underwater landscape

This section of Bai River is about 30-50 meters wide and 20cm-2m deep. The center of the river is filled with varying sizes of pebbles covered with algae. The bottom bed is sandy. The central area of the river has a rapid flow of water, which is clear and oxygen-rich. The flow of water in the shallow water area of the edge of the river is relatively slow, and the river bed there collected a thick layer of soil, which provides a growing environment for plants such as Nymphaea tetragona and Phragmites australis.

Threats to ecology

Beijing as the capital of China has a bustling city center. During the weekends, I prefer to go to the suburbs of Beijing for a chance to wind down and to observe the beauty of nature. Huairou White River Bay Scenic Area is always my first choice, since there exists a wealth of fish and aquatic living resources.

The habitat there is so beautiful that the moment the water laps over the camera, I can glimpse the mystery of another world. In order to capture the beauty of this habitat and to raise awareness for people to protect it, I created the habitat’s biome aquarium.

Comment by the expert

Fan Li: The fishes and system had not reached the good condition.

Zhou Hang: The BAM doesn’t have water current unlike in BIN. Zacco platypus is a top level swimmer but not in BAM, they were swimming at the bottom.
