In this paper, an integrated model that combines bio-physical components related to fire hazards and human behavioral components related to fire risks is proposed. The model is shown to be as an improvement over the theoretical fire danger model. It predicts occurrence/potential based on ignition probability and fire use intentions of forest hikers. Testing of the model was conducted in SheiPa and Yushan National Parks located in central and southern Taiwan. The candidate variables provide acceptable results that support the structure of this conceptual model. Due to limited research time in this study, further tests of the conceptual model are needed to evaluate and improve the performance of the model.
