Fern Communities in Lowland Tropical Forests of Brunei Darussalam, Borneo: Diversity, Indicator Species, and Environmental Drivers Across Forest Types

Biotropica, Volume 57, Issue 4, July 2025.
We investigated fern communities across three lowland tropical forest types in Brunei Darussalam—Mixed Dipterocarp Forest (MDF), Peat Swamp Forest (PSF), and Heath Forest (HF)—using data from 48 plots. We found that species richness, indicator species, and environmental drivers varied among forest types, highlighting the importance of habitat diversity
