Located in a rich biodiversity area where three biogeographic regions meet: Pastizal Pampeano, Espinal and Delta e Islas del Paraná. The site supports internationally threatened species such as the Dot-winged Crake (Porzana spiloptera) and the Chilean Flamingo (Phoenicopterus chilensis). Some endemic species of the region include Straight-billed Reedhaunter (Limnoctites rectirostris), the Bay-capped Wren-spinetail (Spartonoica maluroides), the dark-throated Seedeater (Sporophila ruficollis), and the Marsh Seedeater (Sporophila palustris), as well as a number of mammal species locally threatened by hunting activities, including the Nutria (Myocastor coypus), Capybara (Hydrochaeris hydrochaeris) and other internationally threatened species. The site is dedicated to conservation activities and the main productive activities carried out include livestock, forestation, tourism and agriculture. Among the potential threats that are found in Otamendi are the invasion of exotic flora and fauna species, the pollution of the water bodies, changes in the hydrological system, and extraction of resources. The site is under national protection as a Natural Reserve and is part of the National System of Protected Areas. A five-year management plan is in place.
