### Flora and fauna

Over 3000 plant species have been recorded in the park, including many endemic and endangered species. The mountainous terrain of the park means distinct altitudinal zonation is seen, with the flora changing from tropical plants at low elevations to temperate alpine plants at high elevations. An estimated amount of 25 percent of Vietnam's endemic plants are found on Fansipan mountain.

About one-third of amphibian species present in Vietnam can be found in the park.

A total of 199 butterfly species has been observed in Hoang Lien National Park. For moths, a total of 78 species of sphingidea and a total of 286 species of noctuidae has been observed.

### Mammals and Amphibians

There are ten species of animals and four species of birds which are globally endangered were recorded in the park. The population of mammals in Hoang Lien National Park is low due to poaching.

However, in 1999, it is recorded that there are 347 bird species in and around the nature reserve, including 49 species that are restricted in Vietnam to North-west Tonkin.

A total of 38 different anuran (frogs and toads) species were observed in Hoang Lien National Park in 1997-1998.
