Protected forests in West Java are wider than conservation forests, whereas mammalian diversity in protected forests is as high as mammalian diversity in conservation forests. Mammals in protected forests are not protected by regional protection regulations, while anthropogenic factors in Java are quite high. This is possible that mammals who have high conservation status will experience local extinction. This study aims to determine (i) the composition of mammalian species and (ii) the species that are always found in studies of mammalian diversity in West Java. The study was conducted through a qualitative approach by combining several methods such as interview, camera trapping, sign survey, observation and transect, and collapsible traps. Mammalia in West Java found 54 species, 21 families, and nine orders with details of three species of Artiodactyla, 12 species of Carnivores, seven species of Chiroptera, one species of Dermoptera, one species of Euphotyphla, one species of Pholidota, five species of Primates, 21 species of Rodentia, and three species of Scandentia. The species that are always found in all study locations are nine species, including wild boar, Javan leopard, leopard cat, Javan mongoose, oriental small-clawed otter, Asian palm civet, grizzled leaf monkey, Javan langur, and Javan tree shrew. The results presented here may facilitate improvements in the mammalian diversity database, especially in the non-conservation area. INTRODUCTION The diversity of mammals found in Indonesia is 720 species or more than 13% (Widjaja et al. 2014). Several of this species are found in West Java, one of the provinces in Indonesia that has a distribution of protected areas. The forest area as a habitat for most mammals tends to be concentrated in the Southern part of West Java which stretches from Sukabumi, Cianjur, Bandung, Garut, Sumedang, Tasikmalaya, Kuningan, and spreads to small parts in Purwakarta, and Subang (West Java Regional Environmental Management Agency 2008). Among these forest areas, Cisokan, Ciletuh, Kamojang, Darajat, and Gunung Salak are known to have various species of mammals based on previous studies. Based on data from the West Java Forest Service, the forest area in West Java in 2017 is known to be conservation forest of 139,790.08 hectares, while protected forest area of 274,830.62 hectares (Central Bureau of Statistic 2018). This shows that protected forests are more extensive than conservation forests. Most of the diversity and population ecology of medium and large mammals are targeted on National Park and sanctuaries of the country (Mohammed and Afework 2014), but outside of the protected areas records and conservation status of the different species of mammals are poorly known (Rabira et al. 2015). Some study areas is located in the non-conservation forest areas in West Java, which are not protected by regional protection regulations. This unprotected area is inhabited by species of mammals that are protected both by national and international regulations. Besides that, the presence of endangered mammals in that unprotected area in West Java that has high anthropogenic factors will certainly increase the chances of local extinction. Many larger mammals are extinct on the island or have a highly fragmented distribution (Nijman 2013), putting an enormous pressure on biodiversity (Miettinen et al. 2011). Threats include forest decline, but also trade in wild animals for pets, traditional medicine or other economic uses (Rode-Margono et al. 2014). In the previous study, it was known that several species of mammals with high conservation status, such as the Javan leopard (Panthera pardus melas), Silvery gibbon (Hylobates moloch), Malayan pangolin (Manis javanica), and many more are exist in this areas. Previous studies of biodiversity have been conducted in West Java, especially Ciletuh, Cisokan, Kamojang, Darajat, and Gunung Salak. This research was conducted to determine the latest condition of mammalian diversity by using a combination of several research methods, so the expected information related to the diversity of mammal species can be more comprehensive.
