Abstract


Meru Betiri National Park (MBNP) is one of the nature conservation area thathas the potential of
flora, fauna, and ecosystems that could develop as a nature-based tourism attraction. The existence of
certain indicator species was related to estimation of stress level and disturbance on ecosystem stability
for making strategic decisions about the restoration in this area. One of the important indicator species
at forest ecosystem were soil arthropods. Aim this research were analyzed composition and diversity of
soil arthropods at Rajegwesi, MBNP areas. The methods in this research used pitfall trap, measurement
of distribution structure and soil arthropods composition based on the Shannon - Wiener index,
Morisita similarity index and Importance Value Index (IVI). The number of families and individuals of
soil arthropods found in the coastal area of Rajegwesi consists of 10 order with 21 families (702
individual). The number of individuals of the order Hymenoptera, Coleoptera, Collembola and
Araneida was more widely found. Soil arthropods diversity index on each land use indicated that soil
arthropod diversity in these areas were moderate. Soil arthropod community of orchards and forest
had a similarity of species composition, whereas soil arthropod community of savanna had a similarity
of species composition with paddy fields.
