Ottelia acuminata reappear on Erhai

On the Erhai Lake in west Yunnan’s Dali, ottelia acuminata, an indicator of clean water, was once out of sight due to pollution. At the end of 2016, Yunnan launched an environmental campaign to protect the lake. In June 2020, ottelia acuminata reappeared in the clear lake waters.
