Lilium philippinense, commonly known as Benguet lily, is an endemic plant species that is native to the Cordillera Administrative Region (CAR) of Northern Luzon in the Philippines. Despite its status as a high-priority endemic plant species, the conservation status of this species remains a major concern due to its declining population caused by anthropogenic activities and intrinsic biological constraints. This study aimed to systematically synthesize existing research on the threats to and conservation of Lilium philippinense and identify study gaps to support future conservation planning and research. This analysis used a systematic review that followed the PRISMA guidelines to gather and analyze five peer-reviewed studies published from 2010 to 2025. A total of 42 records were screened, and after applying the inclusion criteria, five articles met the final requirements for the synthesis. This study reveals that the survival of Lilium philippinense is impacted by land development that is primarily attributed to urbanization and unregulated plant collection practices. Although there are conservation efforts in place, it was reported that there is low reproductive success in both in situ and ex situ methodologies, consistently demonstrating poor growth and low survival rates. This study highlights the need to apply research findings to future conservation plans and actions by strengthening policies that protect their habitat, improving propagation techniques, and addressing ecological knowledge gaps to enhance the long-term survival of Lilium philippinense.
