735:. It takes up 886 square kilometres (342 sq mi), of which 106 square kilometres (41 sq mi) are the core protected area. It is an area rich in biodiversity, including species that find their southernmost limit of distribution, which makes the area interesting for the conservation of genetic diversity. The main human activity in this part of the delta is the exploitation of the willow forest for commercial purposes, and human impact is low. The region has suffered from a loss of human population and today there are only 3,600 inhabitants 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 and support the investigation and study of the ecosystem with the possibilities of national and international investment in projects of sustainable growth and the grouping of the region in reference of organic cultivation and varied ways of land-forest production with certification of ecological quality.

mild spells in the winter when the temperatures might reach 25 °C (77F), followed by much colder weather and frosty nights. Temperatures usually reach 0 °C several times a year, yet they rarely fall much lower than -3 °C (27F), with record lows approaching -7 °C (19F). However, generally speaking, the windy, humid weather makes it feel significantly chillier than indicated by real temperatures.

Due to the low elevation and the ubiquitous presence of water, the Paraná delta is subject to a particular climate within the climate zones of the Pampas. As in the entire region, there are four distinct seasons; however, the Delta has slightly colder nights, milder winters and higher humidity, which

The Lower Delta was the site of the first modern settlements in the Paraná-Plata basin and is today densely populated, being the agricultural and industrial core of
Argentina and host to several major ports. The main course of the Paraná lies on the west of the delta, and is navigable downstream from

Spring is usually delightful, yet very sudden changes may occur: summer-like and winter-like temperatures often alternate, and there may be a large difference between day and night temperatures. It is also the season most prone to violent weather. October has the same average temperatures as April,

The Paraná Pavón is the first major branch. It has a meandering course that starts on the eastern side, opposite Villa
Constitución. Between the main Paraná and the Paraná Pavón lie the Lechiguanas Islands. The Paraná Pavón flows east and then turns south to be continued by the Ibicuy, which itself

In turn, the Paraná Guazú sprouts two east-flowing branches in the territory of Entre Ríos: first the Paraná Bravo, and then the Paraná Miní.
622:
Winter runs from late May to late August. Temperatures usually range from 13 °C (55F) to 18 °C (64F), while nights go from 3 °C (37F) to 7 °C (45F), with lower precipitation but higher cloudiness and relatively common fog. As in the entire Pampas region, there are often brief,

Summers are hot and often muggy; with daily highs between 18 and 22 °C (64 and 72 °F) and nights between 16 and 20 °C (61 and 68 °F). Heat waves are common, yet they are not as intense as in central
Argentina, and usually temperatures will not go much above 36 °C (97F),

Islands Ecoregion. The original ecosystem, especially in the Lower Delta, has been heavily modified by deforestation, hunting, fishing and the introduction of foreign species of flora, as well as damaged by domestic and industrial

March is already noticeably cooler than the summer, and April is characterized by very pleasant weather: highs range from 21 °C (70F) to 25 °C (77F), nights from 10 °C (50F) to 14 °C (57F), and May is already generally cool, with chilly nights.

Precipitation in the region ranges from 1,000 to 1,400 millimetres (39 to 55 in), with two peaks in late spring / early summer, and late summer / early fall, and a drier, yet cloudier winter.
