The diversity of fauna collected from foliage and soil of the mowed and tall grassland in De La Salle University, Biñan, Laguna was analyzed using diversity indices: Shannon index of diversity (Hˈ) and evenness (J), and Simpson index of diversity (SID), dominance (D), and equitability (E). Diversity indices values for foliage of mowed grassland are (Hˈ=3.28; J=0.89; D=0.05; SID=0.95; E=0.02), while soil fauna of mowed grassland have diversity indices values of (Hˈ=1.87; J=0.85; D=0.18; SID=0.82; E=0.09). Arthropod diversity in foliage of tall grassland have values of (Hˈ=2.42; J=0.80; D=0.13; SID=0.87; E=0.04), while diversity indices values of soil fauna in tall grassland are (Hˈ=1.69; J=0.73; D=0.13; SID=0.87; E=0.09). The values indicate that fauna in mowed grassland are more diverse compared to the fauna of tall grassland. This suggests that mowing increased the fauna species diversity in the mowed grassland, compared to the stable and undisturbed community of tall grassland.
