Abstract

Wana Patra Lestari (WPL) is a remaining forest in the center of Balikpapan City. It is located in the working area of PT Pertamina Refinery Unit (RU) V Balikpapan. Besides having cultural and historical value, the existence of the WPL area also has environmental service value as a habitat for birds and mammals. This study aims to analyze the diversity of bird and mammal species in the WPL area. We collected all related bird record by using a combination of point count and mist-netting methods. Furthermore, mammal was sampled by using a combination of line transect, live-trapping, camera-trapping, and also mist-netting survey. The results showed that in the WPL area 17 species of birds and 6 species of mammals were identified. There are 14 species of birds and 2 species of mammals added from previous studies. Of all the identified species, there is only one protected species in Indonesia, namely Elang Bondol (Haliastur indus). Periodic monitoring is needed to find out more about population dynamics and diversity of wildlife in the WPL.
