Twenty-four students from universities in HCM City were working as volunteers at the Hon Me Wildlife Rescue Station in the Cuu Long (Mekong) Delta province of Kien Giang.
They helped prepare food and feed animals at the rescue station.
They also painted animal enclosures and planted trees during a five-day trip organised by the non-profit organisation Wildlife At Risk (WAR) from June 25 to 29.
The volunteers and local rangers have distributed leaflets that provide information on wildlife conservation to 500 local families in the province's Hon Dat District.
