"Trees or shrubs that grow below the minimum line and above the average line of tropical or subtropical coasts are called mangroves", which is a narrow definition of mangroves. Mangroves are very interesting plants, such as viviparous, respiratory roots, supporting roots and other special evolution. Mangroves have certain functions, which can maintain the rich ecology of coastal wetlands, as well as wind protection and tidal erosion resistance. Where does the middle name of mangrove come from? The answer is that red dye can be extracted from its bark, so it is called "mangrove". Unfortunately, red eggplant and thin-core mangrove called "mangrove" no longer exist. The mangroves in Kaohsiung, Taiwan Province Province used to be mangroves, red tomatoes, China shrubs, Wuliluo, tomatoes and plums, but now there are only the last four kinds of mangroves, which used to be easy to see in the western part of the province. Kaohsiung Port Area is a paradise for mangroves and red tomatoes, and it has been listed as extinct today. The place name of Solanum nigrum originated from Solanum nigrum, and the old place name of Yong 'an "Wushulin" also refers to mangrove forest, which shows the status of mangrove forest, but it is now listed as a rare plant. There are four kinds of mangroves in Kaohsiung, but the pollution is serious, which conflicts with the environmental development. There are one kilometer-long jellyfish on both sides of Dianbaoxi and Cheduxi in Qizailiao mangrove trail, and the nearby Qiliao country has also actively established an ecological teaching park, starting with the establishment of mangrove trail. Among the four mangroves in the province, there are three species in this area. The eggplant forest is mixed with five pears and Chinese brush, but the number is single digits, which is very precious. Fortunately, the teachers and students of nearby schools continue to observe and study, and this area will become the best place to preserve mangroves in Gaoxian County. Yong' an seaweed ditch is almost full of rows of seaweed in the drainage channel of the whole Yong' an aquatic fish culture area. In the old society, seaweed can play a very good role in preventing the wind from freezing fish in winter, and it is also the source of firewood. Nowadays, plastic gauze is used to prevent wind, and road widening has also destroyed many passages. The sea otters on the roadside are covered with a thick layer of dust, and some of them have died, leaving silvery branches with a different kind of poetry. Another mangrove ecological zone in Kaohsiung County, Zhao Chao, Daxinggang Lagoon is located between Yong 'an and Qiyong. It is an eggplant forest dominated by intertidal organisms. Find a shore to stand still, and soon fiddler crabs and mudskippers will move around. However, this area also overlaps with the scheduled location of Daxing Ocean Culture Park, hoping to preserve the rich and interesting ecological landscape of this area. In other areas, only jellyfish on both sides of Agongdian River in Yong 'an and the floodplain on the west side of Shuang Yuan Bridge in Gaopingxi are left. The Shuibizai mangrove restored by the county and the New Hope Foundation represents the beginning of new hope.
