Abstract
Due to the rapid changes of global environment and warming, the global environment and climate change has become the world's governments to the science and technology research and development of one of the primary project, and our government has realized according to the urgency of climate change impact of Taiwan, over the past 20 years, actively integrate relevant departments devote quite heart and financial resources, to conduct research and policy making, hope to improve the national adjustment ability, which reduce the impact of the environment. The impacts of climate change on biodiversity and ecosystems have also been studied and discussed. Most of these studies focus on the changes in the distribution of natural forest flora, the threatened migration of species in various forest phases, the impact on the carbon sequestration of forests, and the decline of forest ecological functions. There are long-term forest survey and historical climate data in Taiwan, but the research on the optimal location and possible change of production of tree species for economic afforestation in the context of climate change is still insufficient. In addition, due to global climate change, extreme events happen more frequently, for ecological environment disturbance, easy to damage and produce new habitat disturbance, all kinds of species to adapt to the new habitat migration ability is more important, because the only species which can be a quick adjustment to adapt to survive, and maintain the ecosystem, the complete and operation. Forestry research in Taiwan has been developed for more than 100 years, but no integrated database of forest plant basic functional characteristics or model parameters has been established. It is a pity that the previous research results are scattered in the literature and cannot be utilized systematically. As a result, forestry workers and researchers cannot easily obtain the large amount of research results accumulated from previous forestry research in the assessment, strategic planning and research of the impact of climate change on forests. In light of the above, this project: Adaptive mechanisms of species and estimation in the growth potential of forest plantations under climate change , include five parts, respectively: 1. Functional traits of database of adaptive species in disturbance area under climate change, 2. Identification and adaption mechanism of desiccation-tolerant ferns, 3. Climate change meets habitat fragmentation: Functional traits of vascular epiphytes as potential indicators of environmental conditions in forest ecosystems, 4. Estimation in the growth potential of forest plantations and its adaptive strategy under climate change, and 5. Building the databases of basic properties and model parameters for the woody plants in forests of Taiwan.
