Nam Cat Tien is contiguous with Vĩnh Cửu nature reserve thus providing an enlarged area for species to breed.

Parts of the park area suffered historically during the Vietnam War when it was extensively sprayed with defoliant herbicides.

A large number of gold, bronze, ceramic, coloured stone, and glass artefacts are currently displayed in the Da Lat museum.

"It appears to be a very good competitive species able to regenerate on denuded areas: along roads and on land abandoned after cultivation.

The low canopy and under-story zones contains species such as the endemic Cycas inermis; a number of palms are common, including Caryota mitis, Licuala and Pinanga spp., together with a wide range of fruit species (important food for animals) such as figs (e.g. Ficus racemosa) and wild bananas (Musa acuminata).

Lianas are abundant and include: Ancistrocladus tectorius, box beans: Entada spp., 'monkey ladders': Lasiobema scandens and Rattans: especially Calamus spp.

Numerous endemic species, having their type locality at CTNP, have been described by Vietnamese and international scientists: including those at the Vietnam-Russia Tropical Centre.

More than 20 species of organisms have the name "catienensis" or similar, including two palms (Licuala illustrated here), the bracket fungus Tomophagus cattienensis, two reptiles and four insects to date.

There are also records of banteng and kouprey, but the latter may now be globally extinct, and wild Asian water buffalo no longer occur in Cat Tien.

Lizards: Snakes - 43 species recorded including: Frogs: The most developed insect lists currently cover ants, butterflies, dragonflies, mosquitoes and termites; of the latter, Macrotermes spp.

In 2008 the Forestry Protection Department collaborating with the Endangered Asian Species Trust (UK), Monkey World Ape Rescue (UK) and Pingtung Wildlife Rescue Centre (Taiwan) founded the Dao Tien Endangered Primate Species Centre.
