Abstract. Ardiyaningrum I, Budiastuti MTS, Komariah. 2021. Short Communication: Species composition and diversity of vegetation in dryland agricultural landscape. Biodiversitas 22: 65-71. Drylands are a part of the terrestrial ecosystems with a relatively larger area compared to wetlands. Selo has dryland with steep slopes and high rainfall, resulting in relatively high soil erosion. The land use in this sub-district is dominated by plantations and agriculture, with conditions that have not been fully balanced by trees as a means of controlling erosion and supporting vegetation diversity. Therefore, studies on biodiversity are important as an indicator of dryland sustainability, especially in terms of soil and water conservations. This research aimed to study the species composition and diversity of vegetation in the dryland agricultural landscape in Selo Sub-district, Boyolali District, Central Java Province, Indonesia. Vegetation analysis was performed by using the quadratic sampling technique for tree category, pole category, sapling category, and seedling categories. The results indicated that Fabaceae had the highest number of species. Tree species with the highest Importance Value Index were Toona sureni, Artocarpus heterophyllus, and Casuarina junghuhniana, respectively. The Shanon-Wiener Diversity Index showed that the vegetation at tree, pole, and sapling stages had a moderate diversity, and seedling-stage vegetation had a low diversity.

       Land-use change forest conversion and poor land management have damaged forest ecosystem. It is automatically disturbing the components in the forest ecosystem, among other soil arthropods. Therefore, environmental friendly land management system is required. One such system is Sengon-based Agroforestry with Porang Cultivation. The objective of research is (1) to understand the structure and function of soil arthropods in the Porang and non-Porang lands; Research is conducted at KPH Saradan, Madiun Regency. Two locations are chosen, Agroforestry land with Porang cultivation and non-Porang Agroforestry land. Method of research is observational survey. Sampling technique toward Arthropod is Pitfall Trap. Result of research indicates that the diversity of soil Arthropods family in the Porang land is counted to 27 families, while in the non-Porang land, 30 families of soil Arthropods are estimated. Shannon-Wienner Diversity Index in the non-Porang land is in low category with H>1 (1.32), while the diversity index in the Porang land is in very low category with H<1 (0.83). Bray-Curtis Index, which is measuring the similarity of two compositions of land community in the Porang and non-Porang lands, is counted to 0.91, submitting to the category of not different. The community of land Arthropods in the Porang land plays some roles such as soil decomposer (57 %), litter transformer (22%), and predator (21%). The roles of litter transformer and predator have similar rate (26 %).
