Potential of Agricultural Plantations and Orchards to Support Understory Forest Bird Diversity in Southeast Asia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study assessed the potential of monoculture oil palm and rubber tree plantations, as well as polyculture orchards, to support understory bird diversity compared to forest reserves using mist‐netting. Orchards recorded the highest bird abundance and richness among agricultural lands, but all agricultural lands had less than half the understory bird
