A latest report on aquatic wildlife at a nature reserve around Huairou Reservoir in northern Beijing has revealed that some rare aquatic species have been found for the first time in the region.

The first ever such report was based on a two-year scientific fact-finding mission conducted by Beijing Normal University, supported by Beijing Environment Protection Bureau. It touched upon the nature reserve's overall environment, its fish, birds, insects and plants.

According to Beijing Daily news, what the report has found at the aquatic wildlife nature reverse around Huairou Reservoir where Beijing's Huaisha and Huaijiu rivers crosses each other, include 23 species of fishes, 96 species of birds, 7 species of mammals, 226 species of algae, and 201 species of vascular plants.

These surprising findings also include some rare species that are for the first time to be found in the region, like Chinese nine-spine stickleback, water shrew, and a wild mandarin duck and a white-tailed sea eagle that are on china's top national protection list.
