Abstract

Soil insects play an important role in maintaining forest soil fertility. Soil insects ingest the decomposing organic matter and transform them into simpler substances for plant nutrients and improve soil physical properties (Borror et al. 1992). This study shows that in Gunung Walat University Forest, species Rhinotermitidae 1 (termites), Formicidae (brown ant), and Scarabaeidae (larvae of Coleoptera) possesed the largest abundance in stands of agathis, pine, mixed forest and burnt pine. Soil insect abundance was greatest in agathis stand with low crown density. Insects were more abundant in soil than in litter. Mixed forest stand possesed the largest soil insect diversity as compared with other stand types.

Abstract

Soil macrofauna is part of the soil biodiversity that plays an important role in the improvement of the physical, chemical, and biological properties of soil through the process of immobilisation and humification. Soil macrofauna have roles in the process of fragmentation, as well as providing environmental facilities (microhabitat) for facilitating the decomposition process which is conducted by soil mesofauna and microfauna and various types of bacteria and fungi. The aim of this research is to identify and measure the diversity of soil macrofauna in different types of forest stands of Gunung Walat University Forest (dense and sparse agathis stand, dense and sparse pine stand which were either burnt or not burnt, and dense and sparse mixed stand). The study showed that the highest abundance was in the stand of dense Agathis. Mixed stand (mixture of Agathis, Pine and Altingia excelsa) showed the highest soil macrofauna diversity. The classes of Oligochaeta and Geophilomorpha were most commonly found on every type of stand in Gunung Walat University Forest.
