Abstract

This study provides a list of Hoya species found in Quezon province, Luzon Island, Philippines. Several literature revealed that there are 39 species and six subspecies of Hoya found in the province of Quezon. From these species, 37 are endemic in the Philippines and two are indigenous. Human activities that can lead to forest degradation like illegal logging and slash-and-burn farming were identified as threats to the survival of the Hoya in Quezon. Protection of the forest habitat, the home of Hoya, as well as conducting assessment of the conservation status of these Hoya in the local level are recommended in order to strengthen the conservation efforts to protect the Hoya in the province.
