\textbf{INTRODUCTION}     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). \cite{antos2014camera}.  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 \cite{carrillo2000monitoring, schipper2008status, rodrigues2009boom}.   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}, which presents one of the highest population growth rate of the world \cite{cincotta2000human}, increasing the demand of goods, resources and infrastructure.
