At ECOSARA you will be looked after by a permanent staff of trained zoologists who´s job it is to oversee the research work as well as to make sure your every need is attended to! All staff members are bilingual (in some cases trilingual!) and have extensive experience of field work in Paraguay. These are the guys who will tell you what that frog is chirping in the reedbed, help you identify the hummingbird that whizzed past your bedroom window and teach you how to recognise the species responsible for the fresh footprints that accumulate around the lake each morning.

Uruguayan herpetologist Pier is well on his way to becoming the country´s leading authority on reptiles and amphibians. In addition to publishing numerous scientific papers and books on Paraguayan and Uruguayan reptiles he has worked extensively studying the species present in the park. Remarkably he has discovered no fewer than three species of reptiles new to science within the park boundaries and is convinced that more lay out there awaiting discovery.
