A research team from the University of Lampung recorded 35 bird species from 19 families, totalling 167 individuals in the Wana Jaya Community Forest (HKm) area, KPH Batutegi, Tanggamus Regency, Lampung Province. Published in the Journal Wasian, the study compared three land cover types within a single hilly landscape: forest, coffee-based agroforestry, and coffee monoculture. The results show that while forest holds the highest bird richness, mixed coffee gardens remain significant habitats for many bird species.

Forest recorded 26 bird species, whereas coffee monoculture had only 11 species. Species diversity values across the three land types were moderate, with forest highest (2.988), followed by coffee agroforestry (2.648) and coffee monoculture (2.035). Notably, insectivorous birds dominated in all habitat types. According to the study, this indicates unexpected ecological resilience in the tropical forest-coffee landscape. Of all recorded species, 10 are protected under national regulations and three are listed in CITES Appendix II.

For local communities around the forest, these findings provide a strong rationale for retaining trees in coffee gardens. Coffee agroforestry does not replace forest, but can serve as supporting habitat for birds, including protected species. The researchers also noted that forest cover in HKm Wana Jaya is not dense due to resin tapping activities and land clearing for coffee monoculture.
