The diversity and density of soil macrofauna are indicators of forest soil health. They play a direct or indirect role against various physicochemical processes in forest soils. This study explores the diversity and density of endogeic and anesic soil macrofauna on three types of land cover and the factors affecting it in UNS ‘Mount Bromo’ educational forest in Karanganyar Regency, Indonesia. Soil macrofauna inventory research was conducted using the soil monolith method measuring 25 cm x 25 cm x 30 cm, on three land covers in UNS educational forest, including pine, mixed pine – mahogany, and open land, repeated sampling 12 times. Data analysis using SPSS version 16.0. The results showed 11 endogeic and anesic macrofauna orders on all three land covers, and Hymenoptera and Isoptera were the two dominant orders. The highest diversity of soil macrofauna (H’=2.37) is found in pine-mahogany mixed land, while the population density in all three land covers is between 534 to 678 individuals/m2. The soil organic C content in all three land covers determines the diversity of the endogeic and anesic soils macrofauna (r=0.36*). Management of tree diversity that improves the C content of soil needs to be pursued on various types of land cover in UNS educational forests so that the health of the land is maintained.
