Within the Biosphere reserve we use two main field camps, they are similar in their accommodation but their habitats are vastly different. In KM19 and Hormiguero all participants sleep in tented accommodation, there are dry toilets and bucket showers. There are areas for lectures, communal dining and data processing. Our third camp Dos Naciones is a little different, a much more remote camp, which offers the most intense jungle experience on the Mexican project. Accommodation here is in hammocks with integrated tarps and mosquito nets arranged around a campfire. There is a trench toilet and bucket shower system to avoid as much impact on the forest as possible.
