The remarkable natural phenomenon of "tidal trees" in the Qiantang River, a waterway in east China's Zhejiang Province famous for having the world's largest tidal bore, has entered the best viewing time.

As the tidal flats of the Qiantang River estuary are at their largest of the year in March, spectators are presented with the spectacular sight of "tidal trees," which are caused by the tide washing the silt and vegetation on the tidal flat.

"Tidal trees" carry important ecological significance and have been closely studied by researchers as a part of the Qiantang River Estuary ecological monitoring work.

"Tidal flats are areas where terrestrial ecosystems and marine ecosystems converge. 'Tidal trees' spread out on tidal flats, serve as highways for the exchange of matter and energy between the land and the ocean. Fish, shrimp, and seeds can quickly spread out through the flow of water," said Chen Fuyuan, director of the Zhejiang Institute of Hydraulics and Estuary's estuary research laboratory.
