AB -The geographical distribution of Lilium philippinense Baker in the Cordillera Central Range (CCR), Luzon Island, Philippines has not been accurately recorded in previously published literature. The need for this type of study for L. philippinense becomes more immediate due to the decline of its population. The output of this paper is the identification, establishment and description of the geographic distribution of L. philippinense, an endemic species in the region through extensive survey of the entire CCR. Mapping the 118 natural populations of L. philippinense in the entire study area using Geographical Information System (ArcMap of ArcGIS 9) shows a narrow and fragmented distribution pattern, specifically on the southwestern slopes of the CCR.  Descriptive analyses reveals that the populations are distributed at an altitudinal range of 754 and 2,155 m and geographically located between 16º27’90” and 17º15’55” latitude and  120º51’86” and 121º09’22” longitude. In addition, results of hierarchical cluster analyses and analysis of variance also show that elevation plays a major role in the distribution of this species. Moreover, threats to this species are also determined. Information derived from this study can be of aid to biologists and conservationists in developing strategies to protect this endemic and threatened species.
