Le Ngoc Tuan, head of Hue's Forest Protection Department, said the animals had been handed over in 25 separate cases across the city.
The total included 12 Group IB animals, Vietnam's highest protection category, among them two water monitors, three Sunda pangolins, two pygmy slow lorises and several other rare species.
Another 10 animals belonged to Group IIB, including a black eagle, elongated tortoises, Indochinese box turtles, water monitors and four-eyed turtles, among other species.
Most recently, on June 14, forestry officials received a rare four-eyed turtle voluntarily handed over by a resident in Binh Dien Commune. Around the same time, another resident turned in a yellow-headed box turtle weighing about 0.7 kilogrammes.
Earlier, on June 10, authorities received a Sunda pangolin weighing about 1.6kg after a local resident found it abandoned in a mesh bag on a street in Hue.
Recognising it as a protected wild animal, the resident handed the pangolin over to local authorities.
Forestry officials said the growing number of voluntary handovers reflected increasing public awareness of wildlife conservation and compliance with environmental protection laws.
Animals deemed fit for release will be cared for, rehabilitated and returned to their natural habitats.
