The Yok Don National Park in Dak Lak Province has seen its largest and most diversified herd of wild elephants entering the park, its director said Friday.
The 32-member herd has five to six mature tuskers and four to five young elephants, Truong Van Truong said.
They were discovered during a routine patrol by the park guards, he said.
Truong said the arrival of so many elephants could be a sign that biodiversity at the park has improved.
Officials at the park have enhanced patrol and observation at the elephant area and informed nearby residents of the elephants, so they use noise and fire to drive them back from residential areas, if necessary, he said.
Yok Don was last year designed to house a 200-hectare elephant sanctuary after officials found Dak Lak, which has the country's largest wild elephant population, was losing the pachyderms to poachers while domestic elephants were being killed by overwork and improper care.
The project is expected to begin implementation this year.
