The assessment of vulnerability level can help the policy makers to develop strategy and actions for managing fire risk and also to develop spatial plan that can lowering the fire risk. The purposes of this research were to determine the variables that affect the level of vulnerability of forest and land fires, to determine the level of fire vulnerability of spatial models and to determine the areal distribution of forest and land fires in North Sumatera Province. Composite Mapping Analysis was used to develop spatial model of forest and land fires vulnerability level. The study found that the most important role factors of forest and land fires vulnerability model is land cover which have almost 38% of weight from nine variables. The study also found that shrubs and grassland are land cover type that almost became the initial source of fire in North Sumatera Province. Padang Lawas District and Labuhan Batu Selatan District have the most extent area of very high vulnerability level. This study provided suggestions to North Sumatera Province stakeholders to enhance intentions to improve land productivity, to improve land rehabilitation and to extent land clearing without burning.
