| 摘要: | 諸羅樹蛙為台灣二級保育類及特有種，分布於雲嘉南，其棲地主要為與人生活重疊的淺山地帶，且其分布狹隘，因此隨著人為開發，其棲地逐漸破碎及消失，族群數量也不斷減少，但若可以了解族群數量、分布情況及其所面對的困境，便可訂定出適合的保育策略。本研究以嘉義縣大林鎮為研究樣區，使用目視遇測法及穿越線鳴叫計數法，透過其鳴叫音量，以QGIS繪測定位以了解其分布，並透過卡方檢定來分析其棲地偏好。研究結果顯示，諸羅樹蛙平均鳴叫音量為80分貝，且不同個體鳴叫音量大小具顯著差異；此外，其分布與河川水系有極大關係。在棲地偏好方面，對竹林具顯著偏好，水田、鳳梨田則顯著不偏好；本研究亦發現竹林為需要翻新之作物。本研究認為聲音地圖使我們得知諸羅樹蛙數量不多的事實，但可根據聲音地圖架設監測站來觀察族群數量，以得知須將保育資源著重放在哪邊的棲地。而竹林雖時常需要翻新，但可以透過導入生態旅遊及建構學習型組織來降低翻新方式對諸羅樹蛙的影響；此外，在本研究之評估中，可做為大林鎮賞蛙夜觀生態旅遊之潛力點僅6處，皆均座落於竹林人為農耕地，因此未來若能透過產業六級化的概念推動生態旅遊以提升竹林產業之附加價值，相信對諸羅樹蛙保育具啟發性的貢獻。
Farmland Green Treefrog is a secondary level protected species and endemic species in Taiwan. It is distributed in Yunlin, Chiayi and Tainan, its habitat is mainly shallow mountainous areas that overlap with human life, and its distribution is narrow. Therefore, with human development, its habitat is gradually fragmented and disappeared, the number of ethnic groups is also decreasing. However, if we can understand the number and distribution of groups and the difficulties they face, we can formulate suitable conservation strategies. This study takes Dalin Town, Chiayi County as the research area. Using the Visual encounter surveys and Audio strip transects, Through the volume of its tweets, map the location with QGIS to understand its distribution, and use the chi-square test to analyze its habitat preference. The research results show that the average decibel of Farmland Green Treefrog is 80, And there are significant differences in the volume of tweets among different individuals; In addition, its distribution is greatly related to the river system. In terms of habitat preference, they had a significant preference for bamboo forests, with paddy fields and pineapple fields being the significant rejection phenomenon; this study also found that bamboo forests are crops that need to be renovated. This study believes that the sound map allows us to know the fact that the number of Farmland Green Treefrog is small, but monitoring stations can be set up based on the sound map to observe the population number, so as to know which habitats should focus on conservation resources. Although bamboo forests often need to be refurbished, the impact of refurbishment on Farmland Green Treefrogs can be reduced by introducing eco-tourism and constructing learning organizations; In addition, in the evaluation of this study, there are only 6 potential spots that can be used as the ecotourism of frog night watching in Dalin Town, all of which are located in man-made bamboo forest, Therefore, in the future, if we can promote ecotourism through the concept of six-level industrialization to enhance the added value of the bamboo forest industry, I believe it is an inspiring contribution to the conservation of Farmland Green Treefrog. |
