Insects are the dominant group of organisms and act as indicators of biodiversity, ecosystem health, and landscape degradation. The research objective was to determine the spread of insects in the Mount Nona Ambon Protected Forest. The research was conduct in January - March 2020 using Pitfall traps, light traps, Sweep nets, Bait traps, namely detergent, sugar solution and tuna fish. The research was carried out in 2 ha as many as five lanes with a systematic inventory sampling method where the length of the line was 100 meters, 20 m wide and 20 m spacing between lanes. The analysis use descriptively quantitative by calculating the Diversity Index (H ') of Shannon Winner, Abundance Index (K), Dominance Index (C) and Evenness Index. The results of the study found 4063 individuals, 13 species in five orders. The Hymenoptera order dominated the spread of insects in the protected forest of Mount Nona, the Formicidae family with the smallest number of 12 individuals, namely Isodontia auripes from the order Hymenoptera family Sphecidae, and the largest number of them was Anoplolepis gracilipes with 401 individuals from the order Hymenoptera family Formicidae. The difference in insects' spread in the observation path is thought to be caused by differences in microclimate, altitude, vegetation cover, insect movement, light intensity and food availability.

We conducted research on mammals diversity in the Mount Sawal Wildlife Reserve on March 2012. Data collection was obtained by direct observation and interviews. They are includes direct encounters, traces/signs of the mammals presence (ex: faeces, traces/footprints, odors, scratch marks, food scraps, etc.) as well as information from the community around the forest. Observations were carried out in seven observation path/forest block in Mount Sawal namely Belandongan, Cibaruyan Jero, Gintung, Gunung Luhur, Kigugula, Jamikuwu, and Sawah Gunung. We documented at least 10 species of mammals have been recorded, including Panthera pardus melas, Presbytis comata, Trachypithecus auratus, Macaca fascicularis, Muntiacus muntjak, Hystrix javanica, Aonyx cinereus, Prionailurus bengalensis, Mydaus javanensis, and Sus Scrofa. The existence of mammals is relatively evenly distributed in all observation path/forest block in The Sawal Mountain. Six species are protected by Indonesian Law, including Panthera pardus melas, Presbytis comata, Trachypithecus auratus, Muntiacus muntjak, Hystrix javanica, and Prionailurus bengalensis. Information on the diversity of mammals is expected to be a scientific consideration in the management area of the Mount Sawal Wildlife Reserve.

Secondary peatlands located in Kuala Dua Village, Kubu Raya Regency have various types of insects, one of which dominates is ants. Ants are members of the Order of Hymenoptera which have high diversity and complexity as social animals. Ants play a role in spreading seeds, other insect predators, spore spreaders, decomposers, ecological controllers. Information about the diversity of ants in Kubu Raya Regency is still very limited, especially those on peat land in Kuala Dua Village, Kubu Raya District, therefore research on ant diversity needs to be done with the aim to record the diversity of ants on these peatlands. Laying down the observation path is done intentionally (Purposive sampling). The method used is hand collecting and leaf litter sifting. The results shows that seven genera and four subfamily were obtained. Subfamily found is Formicinae, Ponerinae, Myrmicinae, and Dolichoderinae. The Subfamily Formicinae consists of the genus Camponotus, Colobobsis, Polyrhachis, Anoplolepis. The Ponerinae subfamily consists of the genus Leptogenys. Subfamily Myrmicinae consists of the genus Pheidole. The Dolichoderinae subfamily consists of the genus Ecphorella.
