As many as 12 invasive alien species are encroaching upon the Dong Nai Culture-Nature Reserve, threatening the biodiversity of the site.

According to a recent research of the Biodiversity Conservation Agency (BCA) under the Vietnam Environment Administration, the species include five floras, five fishes, an amphibian and a invertebrate.

The BCA said impacts of these species to local ones are considerable, requiring immediate control measures to prevent their harms to the environment.

Climate change is weakening the local species, creating opportunities for the invasive alien species to make their approach, the agency added.

Covering an area of nearly 100,000 hectares, the Dong Nai Culture-Nature Reserve was established in 2004 and recognised as a world biosphere reserve by the UNESCO in 2011.
