Comparative study of collembola community on burnt forest areas and unburn forest areas in ijen crater nature park Banyuwangi

Abstract

Forest fire is one of the most crucial environmental and forestry issues in Indonesia. Forest fires are also frequent in the Ijen Crater Nature Park. Forest fires cause loss of filter and humus which is source of food for soil animals. One of the soil animals that inhabit litter and soil is Collembola. This study aims to compare Collembola community in bunt and unburnt areas of Ijen Crater Nature Park. As well as to know the relation of abiotic factors with diversity, evennes, and richness of Collembola in burnt and unburnt areas. This research is a descriptive explorative research. Data retrieval is done with line transect method. The result showed that Collembola index value on burnt and unburnt areas are significantly different. The dominant species in the burnt area is Onychiurus sp, whereas in the unburnt area is Isotomurus sp. The result of abiotic factor regression analysis showed that temperature, humidity and pH level have relation to index of Collembolas diversity, evenness and richness.
