Laguna Oca del Rio Paraguay, Biosphere reserve in Formosa, Argentina.
Laguna Oca del Rio Paraguay is a reserve covering approximately 10,500 hectares of wetlands, forests, and grasslands along the Paraguay River. The landscape is defined by an interconnected network of water channels and lagoons that form its distinctive character.
The Paraguay River created this abandoned meander over centuries through its natural processes. These geological changes gradually shaped the wetlands and diverse ecosystems that exist today.
Indigenous communities in the area maintain traditional fishing and hunting practices in the reserve's waters, with knowledge passed down through generations. These activities follow the seasonal rhythms of the river and remain central to how local people live and use the landscape.
Visitors can reach the reserve through guided tours from Formosa city. Early morning hours offer the best conditions for observing wildlife and water birds in their natural habitat.
The reserve is known for extensive palm forest areas dominated by white palms that thrive in zones subject to regular flooding. These trees have adapted specifically to the fluctuating water levels created by the river's seasonal patterns.
