Cyclophyllum merrillianum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cyclophyllum merrillianum faces severe pressure from deforestation and agricultural expansion across its limited range in the Philippines. The species' restriction to lowland and montane forests makes it particularly vulnerable to habitat conversion for palm oil plantations and subsistence farming. Mining activities and infrastructure development further fragment remaining forest patches, while climate change threatens to shift suitable habitat zones beyond the species' adaptive capacity.
Habitat
This endemic Philippine species inhabits primary and secondary lowland dipterocarp forests, extending into lower montane forest zones up to approximately 1,200 meters elevation. It typically occurs in areas with high canopy cover and rich understory vegetation, often associated with limestone karst formations.
