Abstract

Fire is a major disturbance in high mountain ecosystems of the tropics. On January 6, 1993, the largest forest fire occurred in the Tataka area since the Yushan National Park (YSNP) was established (1985), affecting 280 hectares of forest. The vegetation conditions in YSNP were examined using normalized difference vegetation index (NDVI) derived from SPOT images to estimate the vegetation damage and recovery associated with the fire event. NDVI variations from 1990 to 2006 were calculated. Spatial patterns on each image were compared to thosebefore the fire disturbance to determine the recovery pattern. The results indicated that the vegetation recovered rapidly in the first 6 years following the fire. Nonetheless, the recovery rates are different among different vegetation cover types. The coniferous forest recovered more rapidly than the mixed forest. The vegetation cover has not attained the level before the fire 14 years after the fire.
