  Assessing the abundance and distribution of terrestrial mammal communities is vital to evaluate the mechanisms they use to adapt to anthropogenic disturbances and promote efficient conservation actions \cite{jenkins2013global}. Yet, we first need up-to-date, accurate and rigorously recorded data of the species present in an area to provide the basis of further analysis (Antos & Yuen, 2014). This is especially important for medium and large sized mammals inhabiting tropical forests, as they are excellent indicators of ecosystem health, present high levels of diversity, and yet they are highly threatened mainly by human activities such as expansion of the agricultural and cattle barrier, hunting and habitat loss and fragmentations (Carrillo et al. 2000; \cite{schipper2008status}.     These human activities represent a serious risk for the native flora and fauna of the coastal region of Ecuador, located inside the Tumbes-Chocó-Magdalena hotspot \cite{myers2000biodiversity}, (Myers 2000),  which presents one of the highest population growth rate of the world \cite{cincotta2000human}, (Cinccota 2000),  increasing the demand of goods, resources and infrastructure. The coastal forest of Ecuador presents an ideal opportunity to apply standardized methods to collect information on the mammals inhabiting the area.    Several factors have led to an increase in the use of camera-traps in mammal studies over the last decades. These include the opportunity to maximize encounter rate of terrestrial mammals, especially the cryptic ones, they are relatively inexpensive, efficient and easy to provide the basis for a standardized methodology (Rovero et al. 2014; Ahumada et al. 2013)
