Typhoon is the most frequent natural disturbance in northwest Pacific Ocean, and it is an important factor to affect the structure and function of forest ecosystem in East Asia [1, 2]. Recent observations revealed that climate change may alter the intensity or frequency of typhoons in the past decade [3, 4]. Assessing the potential impacts of extreme typhoon events on ecosystem structure and carbon cycle is critical, especially in frequently perturbed regions such as Taiwan (3.7 typhoons/year) [1].
