Wild epiphytic orchid diversity and phorophyte preference along micro-environmental gradients in north-eastern protected forest areas of Bangladesh

Understanding epiphytic orchid diversity and their ecological associations with phorophytes is critical for effective forest conservation. This study assessed species richness, diversity, and orchid-phorophyte interactions along eight micro-environmental habitat variables (phorophyte height, BDH, bark thickness, phorophyte crown height, orchid attachment height, nearest forest edge distance, canopy coverage & elevation) across four protected forest areas in northeastern Bangladesh: Rema-Kalenga
