Comparative study of Collembola community on post fire land, transitional land and control land in teak forest Baluran National Park Situbondo

Surface fires cause loss of vegetation that covers the soil, litter layer, and top layer, which is the central part of the resources and habitat soil organisms, one of which is collembola. The study aimed to determine the comparability of the diversity and abundance of the Collembola community in post-fire land, transitional land, and control land in teak forest Baluran National Park Situbondo. Sampling method with randomized block design was conducted by line transect sampling, a total of 120 plots in three different locations that are post-fire land, transitional land, and control land and the transect based on altitude. Collembola extraction was carried out by Eco 12 modification barless-tullgren extraction tool. The results of this study showed that a total of 547 individuals had included nine species Collembola. Important value index species Paralobella cassagnau dominated on both post-fire land and control land. Lepidocyrtus bourlet is a species dominated in transitional land. The conclusion of this study is differences land take effect of the important value index, biodiversity index (H’), evenness index (E), and richness index (R), this can occur because differences land allowed differences collembola composition and fires affect the presence of collembola.
