 C. HABITAT DISTRIBUTION AND MOVEMENT
Anoa (Bubalus spp.) Are forest dwellers whose lives move where and when encountering enemies anoa will defend himself plunged into a swamp and when forced to fight by using his horns. Plains habitat in tropical forests, savanna, sometimes found in a swamp. Anoa has a habit of wallowing in the water or soak digenangan forest directly adjacent coastal mangrove forests in the sunlight.
Animals also includes swimmers and climbers resilient, they are often seen to swim beach. Another habit that anoa hone or sharpen horns on certain trees, scratching the ground around the landfill feces along its path in the woods. Animals are active both during the day and at night. Additionally creatures including wildlife are very sensitive, the slightest disturbance causes these animals away.
According to Amir (2008), in a research note (progress report) STORMA, movement Anoa (Bubalus spp) occur in groups or alone, and move from a low to a higher place and vice versa. movement is done to look for food or drink and to rest. This movement generally moves with the radius to 3.5 miles or more. Meanwhile, according to Tikupadang and Misto (1994), Anoa roaming the area studied in the Nature Reserve of 5,000 acres Faruhumpenai Mangkutana.
 
 D. FEED
In the wild wild Anoa eating "aquatic feed" which include ferns, grass, budding trees, fallen fruit, and the types of tubers. Based on observations Pujaningsih, et al., (2005) and some researchers reported that lowland Anoa sometimes also allegedly drank sea water to meet their mineral needs. In the highlands, Anoa natural salt lick in order to meet the needs of minerals. (Malik et al., 2004; Pujaningsih, 2005).

When born, the baby anoa fur is golden brown or yellowish in color and very thick. The color will change gradually becomes darker as it develops (Wikipedia The Free Encyclopedia, 2010)
 
F. POPULATION
Little data that can be obtained about the population of definite Anoa Mountains. It is now estimated the population of the entire Anoa Mountains about 3000 to 5000 individuals. Its population declined from 1900, this is caused by habitat loss, hunting and illegal shooting. Estimated at less than 2,500 mature individuals tails. The population of anoa is very worrying, because subpopulasinya located in protected forest areas like the Lore Lindu National Park also experienced a decline in population caused by high hunting. There are three areas where the population dropped dramatically anoa, namely in Gorontalo, Buol and Tolitoli district (Wikipedia The Free Encyclopedia, 2010)
 
 G. STATUS PROTECTION:
Anoa is one of the rare wildlife that is protected by the state pursuant to Law No. 5 of 1990 on Conservation of Natural Resources and the Ecosystem and Regulation No. 7 of 1999 on Preservation of Flora and Fauna. Additionally anoa animals entered into the list of CITES (Convention on International Trade in Endangered Species of Wild Flora and Fauna) appendix 1 A species that is endangered.
 
 Anoa mountains are usually hunted for their skin, meat and horns. Besides clearing of forests for agriculture and gold mining are also increasingly threatened habitat Anoa Mountains, because he lost habitat and source of food, and he can not adjust to human presence.
