The Atlantic Forest is one of the biomes with the highest biodiversity in the world. Included among the 25 global hotspots due to its endemism, has today, 35% of plant species in Brazil, and many of these species are threatened with extinction. Compared to other countries and even other continents will, the biodiversity of the Atlantic Forest region is of global importance, being essential to their conservation. Brazil has the greatest diversity of World monkeys (48%), and, most endemic country, 2/3 of this amount occurring in the Atlantic Forest. Due to its wild habitat, have suffered great pressure by fragmentation in Atlantic Forest region, restricting habitats of populations to small fragments. The present study consists of a survey of presence and absence of Callithrix aurita, it is a species of primate rare, vulnerable and endemic Atlantic Forest. The importance of this survey is due to the current situation of the Atlantic Forest biome, particularly in the type of vegetation in the region studied, semideciduous forest, where there are the greatest deforestation for agricultural purposes and pasture due to climate, soil type, and other anthropogenic such as property market and building industries. Another factor that was considered is the presence of invasive species as Callithrix jacchus and Callithrix penicillata. The study was conducted in the state of Rio de Janeiro, the city of Sapucaia in the district of Vila Nossa Senhora Aparecida. We evaluated 11 fragments which registered the presence of Callithrix aurita in 8 of these fragments. To assist, we used the method play-back and questionnaires with residents and local workers. The council has a large agricultural exploration, and a total lack of environmental planning by local government. With the results of this survey, along with historical data collected, it was found that the municipality has a high environmental value. Even with the vulnerable status of the species, and its rarity, it is present in 70% of the fragments studied, and no record of invasive species, becoming fundamental to implementing a conservation plan, with the support of the public and society. The objective of this survey is to assist in defining priority areas for future creation of conservation units, using Callithrix aurita as flagship species, assisting in the work of environmental education and public awareness, exploring the potential tourist, historical, religious, among others the municipality for a better environment and a better quality of life for the region's population.
