Abstract
ABSTRACT Hsu, L.-C. and Lee, C.-T., 2018. The current extent and historical expansion of mangroves in the Kuantu Nature Reserve, North Taiwan. The Kandelia candel (L.) Druce mangrove forest in the Kuantu Nature Reserve, North Taiwan, has experienced rapid expansion since 1978. This study assesses the current extent and historical expansion of the mangroves by means of aerial photograph interpretation. An analysis of a time series of aerial photographs, covering the period from 1978 to 2012, has revealed major changes in the distribution of mangroves in relation to the geomorphic changes in the Kuantu Nature Reserve. The results indicate that the area-increasing rate was highest (2.27 ha/y) during the 1986–94 period, meaning the most rapid encroachment of mangroves into the habitats of Cyperus and Phragmites saltmarshes. Based on the Shannon diversity index t test, with the encroachment of Kandelia, the landscape composition in the Kuantu Nature Reserve has been dominated by the mangrove swamp of Kandelia....
