Description

<p>Human activities are causing over-burning and leading to the degradation of the mixed deciduous forest ecosystem in Thailand. This study aims to investigate the current floristic compositions and forest structure in mixed deciduous forests with different fire frequency in Doi Suthep-Pui National Park, Northern Thailand. A ten-year fire frequency map was generated based on satellite data and areas with low and high fire frequency were identified. Then, two sample plots of 50 m×50 m were established in each site. The flora species, floristic characteristics and forest structure were identified and calculated. The results showed that a low fire frequency encouraged the abundance of species diversity in all flora layers which in contrast to a high-frequency fires that caused the extreme diminishment of species diversity, especially in the sapling and seedling layers. Even though the light condition under the canopy in high fire frequency area was better than the low fire frequency area and may encourage the seedlings develop in the rainy season, however, it had been burned back by fire in the following dry season. The high frequent fire affects the plants could not grow beyond the seedling stage. The current floristic composition and forest structure of mixed deciduous forest shows clear evidence of degradation from long-term high fire frequency disturbance. For improving and maintaining a good condition to this protected area, a suitable fire-free interval must be introduced. Thus, a further study that includes information on fuel characteristics, fire behavior and the dynamics of the understory vegetation after burning is recommended.</p>
