Description of Río Pilcomayo National Park

Río Pilcomayo National Park is located 224 mi (360 km) North of Resistancia, Formosa Province in Argentina. Río Pilcomayo National Park covers an area of 47,754 ha (118,000 acres). Río Pilcomayo National Park was found on September 29, 1951 to protect river Pulcomayo and surrounding marshes, creeks, lakes, rain forests and plains. It is situated in the North East part of Formosa Province of Argentina on the border with Paraguay. Río Pilcomayo National Park climate is subtropical. It recieves 1200 mm (47 in) of rain annually, although most of percipitations falls during the wet months of the ear. During summer months (December through February) temperatues can reach 104 degrees F, while in winter (June- August) temperatures can plummet to 30's degrees.
 
Keep in mind that much of Río Pilcomayo National Park is covered by wetlands, area inhabited by many dangerous animals. Treat any body of water with caution. Some of these animals include two caiman crocodile species, including the yacare caiman and the broad snouted caiman. Additionally protected bio reserve is inhabited by several species of constricting snakes that includes the yellow anaconda (Eunectes notaeus) and Hydrodynastes gigas.

 

Characteristic
The area protects a representative zone of the Eastern or Humid Chaco environments. Due to the varied types of climates and soils, there are different plant communities:
Riverside jungle.
Isletas de monte: forest formations in the form of islands.
Savannahs with palm groves: with a discontinuous tree layer and a herbaceous layer.

It houses large species: quebracho, white and red and showy lapachos. Smaller trees grow in the lower strata: carob trees, guayabíes, and drunken sticks.

This impenetrable mountain is inhabited by animals such as the guazuncho (roe deer), capybaras, peccaries, howler monkeys, pumas and birds such as the charata and the ipacahá. In the lower sectors inhabit the maned guazú, the rhea and the chuñas, all of them have the peculiarity of having long limbs that allow them to move comfortably in the high grasslands and flooded areas.

The aquatic environments are inhabited by storks, herons, roseate spoonbills and ducks; also two species of alligators, the black and the overo. Fish from these waters have adaptations that allow them to survive in periods of drought, such as the tamboatá or cascarudo, being able to breathe atmospheric air and change puddles by propelling themselves with their pectoral fins.

This park has been included in the List of Wetlands of International Importance (Ramsar Convention).

It is an area with little slope, with many pastures, estuaries and lagoons. The area is subject to periodic flooding that alternates with periods of drought, creating the vast and growing floodplains in the summer. Subtle unevenness in the terrain allows differentiating sectors with different probabilities of flooding, one of the determining factors of the environmental diversity of the area. Most of the surface of the Park is occupied by grasslands and caranday palm groves, with estuaries in the lowlands and islets of mountains in the highest points.

White palm or caranday: up to 14 m tall and glaucous green palmate leaves; This tree-like monocotyledon is used by parrots and other birds to make their nests. The straw-headed woodpecker and the ñenday parrot nest in the hollows of their trunks. These palm trees are also used as shelter by bats such as the large long-tailed molosser

In the Laguna Blanca, the largest body of water in the park with 700 ha, two species of alligator live: the overo and the black, both in danger of extinction. There are also various snakes such as the curiyú boa and aquatic snakes, among which the ñacaniná stands out. On its coasts there are extensive pehuajozales and pirizales where capybaras and coipos or "otters" live.

Climate
The climatic type of the park is tropical humid without a dry season. Rainfall averages 1,200 mm per year, and the average annual temperature is 23 °C. In summer, maximum temperatures can reach 45 °C and winters are not exempt from days with low temperatures, but these frosts only occur on some occasions.

The area is affected by the South Atlantic anticyclone and by the low temperature of the South American continent, which favor the formation of tropical air masses. The combination of these masses with the polar Atlantic determines the rainfall regime.

In terms of rainfall, they show a marked decrease in the winter season and two peaks of increase, one in the month of March, more accentuated, and another mild in the month of November.

It is important to note that the Park is within the area of ​​frequent production of tornadoes, but there is no good record of them.

Management
By resolution No. 126/2011 of the National Parks Administration of May 19, 2011, it was established that the national park would be classified for administrative purposes in the category protected areas of complexity II, for which it is headed by a designated intendant, On which 4 departments depend (Administration; Works and Maintenance; National Park Rangers; Conservation and Public Use) and 2 divisions (Dispatch and Desk of Inputs, Outputs, and Notifications; Human Resources and Training). The administration has its headquarters in the town of White Lagoon.

Mod cons
