Figure 1. Distribution of camera-traps in the sampled area of Chapada dos Veadeiros National Park (delimited polygon) and its surroundings (10 km from the park boundaries), separated by at least 1 km, in the Cerrado of central Brazil. inserted within the Cerrado biome (coordinates of 13°51' to 14°10'S and 47°25' to 47°42'W). The CVNP is considered the largest area of environmental conservation and the most important ecotourism attraction in the region (Barbosa, 2008). The Cerrado region is located in mid-latitudes and presents the main seasonal climatic type (Aw), with annual temperature between 24°C and 26°C and 90% of rainfall concentrated from October to April, while in the dry season (May to September), the air humidity is very low (below 20% in August and September) and the amount of rainfall can reach zero millimeters in a few months (Marcuzzo et al., 2012). In the region of CVNP, there is a predominance of soils poor in nutrients, which ends up preventing the larger plant colonization, whichever the grasslands of the Cerrado Sensu Strictu (Eiten, 1972; Felfili et al., 2007). In total, the CVNP presents 77% of savanna formation, and 9% corresponds to the forest fragments (Porto et al., 2011). On the other hand, the surrounding of the park has the largest sum of private reserves (Private Reserves of Natural Heritage – RPPN) of the State of Goiás, are 21 RPPNs with 21,515.87 ha (30% of CVNP area) and these are hold a higher percentage of forest cover (Falconi & Diniz-Filho, 2003; Silva et al., 2016). 80% of the RPPNs area, located in the Alto Paraiso region, are protected near the areas sampled in this study (Silva et al., 2016).
