Parana Delta Biosphere Reserve:
Part of the delta was declared Biosphere Reserve by UNESCO in September of 2000 for the the conservation of genetic diversity and the protection of marsh deer, capybaras, wild cats, coipos, river otters and wild turkey. The main human activity in the delta is the exploitation of the willow forest for commercial purposes. Some areas are however difficult to access and human impact is low. The region has suffered from a loss of human population and today there are only 3,600 habitants living there (2001). The establishment of the Biosphere Reserve aims at revitalizing the economy of the region at the same time as conserving the natural and cultural values of the area.
