More than 10,000 mangrove trees were planted around Nha Trang Bay in central Khanh Hoa Province on Saturday.
The planting was done by more than 100 volunteers as part of the province's activities supporting the national Sea and Island Week, which runs from June 1-8 in Ha Tinh Province.
Nguyen Thi Nguyet Ha, deputy director of the province's Sea and Island Department, said the activity aimed at raising community awareness on protecting the sea and island environment from climate change effects.
Nha Trang Bay currently has more than 10 hectares of mangroves. Seven hectares were replanted by different organisations and individuals from 2002.
