- Erhai Lake is also called ‘mother lake’ by the residents of Dali in Yunnan Province of western China. Since 2000, a series of ecological restoration projects have been conducted in Erhai lakeside. Here, we studied the changes in species abundance and richness of the order Odonata caused by this ecological restoration. From 2004 to 2016, we sampled adult and larval Odonata in Erhai lakeside and found 4335 individuals, representing 32 species. Results of our study showed that the abundance and species richness of Odonata varied at different sites of this wetland, but Odonata increased after the ecological restoration compared to those in the pristine areas. We suggest that Odonata is an indicator of the changes in the habitat structure of the Erhai lakeside.
