Maintaining understory vegetation in oil palm plantations supports higher assassin bug numbers

Ecological Solutions and Evidence, Volume 4, Issue 4, October–December 2023., 2023
Reduced understory vegetation complexity in oil palm plantations leads to a significant drop off in numbers of assassin bugs, which are major pest control agents within the system. This suggests that maintaining understory vegetation in oil palm has the potential to boost both biodiversity and pest control.

Rainforest conversion to smallholder cash crops leads to varying declines of beetles (Coleoptera) on Sumatra

Biotropica, Volume 55, Issue 1, Page 119-131, January 2023., 2023
This study compared canopy beetle density and diversity between lowland rainforest and the three main cash crop agriculture systems in Sumatra, Indonesia: jungle rubber agroforest, and monoculture plantations of rubber and oil palm. Focusing on the four beetle families Chrysomelidae, Curculionidae, Elateridae and Staphylinidae, we demonstrate severe ...

No evidence for trade‐offs between bird diversity, yield and water table depth on oil palm smallholdings: Implications for tropical peatland landscape restoration

Journal of Applied Ecology, Volume 59, Issue 5, Page 1231-1247, May 2022., 2022
Tropical peatlands in Indonesia have been drained to allow farmer access and improve farm yields, but we found no trade‐offs between drainage depth, yields and bird diversity on smallholder oil palm farms in our study landscape within the studied range of drainage depths.
