Conservation Value Assessment in Agricultural Area Considering Biodiversity of Insect

Abstract

The agricultural area is a priority to develop than the natural area for land developments. However, the importance of agricultural biodiversity is emphasized recently. The agricultural area does not only provide food for human and habitat for wild life but also contribute to improve biodiversity. It is necessary to preserve the agricultural area with rich biodiversity. The study was conducted to analyze biodiversity of insects for conservation value assessment of agricultural areas. According to the results of field survey, there is higher biodiversity index in agricultural areas surrounding the forest or small size agricultural areas. By contrast, the index is lower in agricultural areas near roads or in the intensive agricultural area. The results show that there is high biodiversity in agricultural areas, especially margin agricultural area such as below 2ha and over slop rate of 15%. Therefore, further studies should be conducted field survey more to generalize for biodiversity in agricultural area, and establish the criteria to protect agricultural area from land developments.

Trophic Ecology of Endangered Gold-Spotted Pond Frog in Ecological Wetland Park and Rice Paddy Habitats

“…Manmade ecological park habitats consist of various habitats that are maintained simultaneously, including ponds, grasslands, forests, and nearby rivers. Unlike rice paddies, ecological parks have forest sections that are positively correlated with insect biodiversity [ 36 , 37 ]. Moreover, ponds within ecological parks provide habitats for various aquatic insects, resulting in high trophic diversity for gold-spotted pond frog diets.…”
