Habitat Complexity Based On Type Of Disturbances In Bukit Bintang And Bukit Angsana Bogor

Abstract

The role of disturbance in shaping biodiversity is widely recognized as a key components of all ecosystem. In this context, human can contribute to the physical disturbances changes, through construction activities in certain landscape or forest followed by desired purposes such as the interest of tourism. Therefore, the value of each landscape necessary to defined, well prior to being used as a nature-based tourism site and it makes them easier to monitor that may influences the quality of a habitat. Considering this alteration, this research aims to analyze the habitat complexity in several landscapes as the consequences of the different type of disturbances in Leuwiliang, Bogor, West Java Province. The research methods consisted of study area identification, microclimate measurements, assessment of habitat complexity parameters, sampling of soil arthropods, identification of soil arthropods, and data analysis. The result showed that habitat complexity index in Secondary Forest, Bukit Angsana, and Bukit Bintang, respectively; 9, 4, and 3. The Shannon-Wiener diversity index in Secondary Forest and Bukit Angsana; 0.78 (low diversity) and Bukit Bintang; 1.25 (moderate diversity). The obtained abundance of soil arthropods in the Secondary Forest, Bukit Angsana, and Bukit Bintang, respectively; 138, 178, and 162. Landscape changes caused by different types of disturbances such as plantations and tourism areas revealed a decrease in their habitat complexity. This alteration in disturbed areas was mostly caused by highfrequency of disruption within forest conversion. For instance, land clearing activities are routinely carried out by tourism management to maintain the cleanliness of the tourism environment. This factor contributes to the slight composition of ground herbage and leaf litter presence in the soil, especially of the litter dwelling arthropods when litter or herb layers are removed frequently. Moreover, anthropogenic disturbances by plantation management and plot maintenance could also affect towards the local species richness and abundance patterns. Lastly, the soil arthropods abundance and diversity on the specific or certain land has their own function and usability to support the assessment of habitat complexity which represented.
