Abstract

Impaired forests by logging may still have a role in germplasm conservation. This study aims to determine the diversity of understory bird species in production forests to identify how important the role of logged-over forests in maintaining diversity and preserving species of birds, especially understory birds. The research was conducted at PT Balikpapan Forest Industries (BFI) and PT Triwira Asta Bharata, East Kalimantan. Observations were made on various logged-over forest blocks with varying degrees of damage ranging from minor to severe.  Data were collected in 32 days at PT BFI and 12 days at PT Triwira Asta Bharata.  Every day 24 mistnets of 10 m x 4 m were opened from 06:00 until 17:00 (11 hours/day) and checked every 15 - 30 minutes. The trapped birds were identified and released immediately. The study captured 696 birds consisting 105 species of 28 families.  There are 20 species from 4 families listed as protected species under Government Regulation (PP No. 7/1999) on the preservation of plant and animal species. Based on Strategic Guidance of National Species Conservation 2008 - 2018, 14 species from 5 families were included in the conservation priority list. When referring to the IUCN Red List, there are 75 species bearing conservation status of Least Concern, 28 species Near Threaten and 2 species Vulnerable. Two species were listed in Appendix II CITES.  From these figures, it is concluded that production forests that have been logged still have an important role in maintaining the diversity and preserving understory birds.
