The aim of the study to determine the composition and abundance of Crustacea and Polychaeta based Mangrove stands in the village of Bulalo Kwandang District of North Gorontalo regency. The research conducted over four months. The method used is survey method and techniques of data collection was done by using a sample square. The data were analyzed by descriptive quantitative. The results showed that crustacea species which consists of 3 family, that is Portunidae, Sesarmidae, Ocypodidae, while the Polychaeta only one family that is Capitellidae family. At station 1 species which have the highest index of abundance that is Sesarma sp. Indv/m2 and 0.189 for species that have the lowest abundance index of 0.023 Indv/m2 Scylla serata. While at the station two species that have the highest abundance index Sesarma sp. of 0.188 Indv/m2 which has an index of abundance and low of Scylla serata the abundance index of 0.020 Indv/m2. The most abundance species found in the Rhizophora sp stands. Where species of the least discovered that the stand Avicenia sp.

This study aimed to determine the community structure of soil Collembola found in Tangale Nature Preserve. The method used in this study is descriptive and quantitative data collection using the line transect is divided into two stations and each station there were 10 sampling plots, using a trap. Data were processed using the formula struktrur community dominance index (ID), Diversity Index (H?), abundance index (J?) and the Density Index (Di) . The results showed that the structure of soil Collembola communities in the Nature Preserve in the midle categories being Tangale. If viewed from the diversity index shows the number 1.377 and 1.374. To the dominance of family Entomobryidae sp. 1 with 0.015 Indv/m2 dominance index, family Entomobryidae sp. 2 with 0.013 Indv/m2 dominance index, family Entomobryidae sp. 3 with 0.07 Indv/m2 dominance index, and family Paronellidae 0.014 sp Indv/m2 dominance index. With an average of 0.253 Indv/m2. for the abundance, family Entomobryidae sp. 1 at 0.512 Indv/m2, and which has the lowest abundance value of the index family believe Entomobryidae sp. 3 of 0.458 Indv/m2. As for the value of the density of family Entomobryidae sp. 1 with a density of 0.0098 Indv/m2 index, family Entomobryidae sp. 2 with a density of 0.0098 Indv/m2 index, family Entomobryaidae sp. 3 with a density of 0.0012 Indv/m2 index, and family Paronellidae sp index Indv/m2 density of 0.0098. The results showed that the structure of soil Collembola communities in the Nature Preserve in the midle categories being Tangale.
