  • Iguazú National Park Argentina
    IGUAZÚ NATIONAL PARK ARGENTINA Iguazú National Park shares one of the great waterfalls of the world with Iguaçu National Park in Brazil. The parks are also an island of the highly endangered Atlantic forest in an area denuded of forest for agriculture. It is one the most complete remnants of a beleaguered ecosystem, 95% of which, in Brazil and Paraguay, has been eradicated. It still harbours one of the great concentrations of biodiversity in Argentina: almost 44% of its avifauna and several threatened mammals. Threats to the site: the scenery and biodiversity of both sites is being degraded and there is no ongoing rehabilitation. COUNTRY Argentina NAME Iguazú National Park NATURAL WORLD HERITAGE SITE 1984: Inscribed on the World Heritage List under Natural Criteria vii and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE [pending] IUCN MANAGEMENT CATEGORY Iguazú National Park: II National Park Iguazú National Reserve: VI National Reserve BIOGEOGRAPHICAL PROVINCE Brazilian Rainforest (8.8.2) GEOGRAPHICAL LOCATION The Park and Reserve adjoining it to the west are in Misiones Province in far northeastern Argentina. They lie 5 km east of the confluence of the Iguazu and the Parana Rivers where Brazil, Argentina and Paraguay meet. The Iguazú River forms its northern border and part of the southern border of Iguaçu Park in Brazil. Located between 25°31' to 25°43'S and 54°08' to 54°32'W. DATES AND HISTORY OF ESTABLISHMENT 1909: A park to protect the falls decreed by Law 6.712; 1934: The National Park officially established by Decree-Law 12.103; 1970: The National Reserve between Puerto Iguazú and the waterfall was excised from the Park by Decree-Law 18.801; 1 1971 The town of Puerto Iguazú was excised from the Park by Decree-Law 18.991; 1972: A further 12,600 ha incorporated into the Park by Decree-Law 19.473.

However, this is only one of the 13 tripartite points that were formed in that continental region from the process of interstate delimitation which occurred, centrally, between the late 19th and early 20th century. Five out of these involve the countries of La Plata Basin, and will be called: Quareim (Argentina-Brazil-Uruguay); Iguazú (Argentina-Brazil-Paraguay); Esmeralda (Argentina-Bolivia-Paraguay); Zapaleri (Argentina-Bolivia-Chile); and Bahía Negra (Argentina- Bolivia-Brazil).

ARGENTINA, BRAZIL, AND THE DE LA PLATA RIVER BASIN: A SUMMARY REVIEW OF THEIR LEGAL RELATIONSHIP GUILLERMO J. CANO* THE PHYSICAL FRAME The De la Plata River, formed by the confluence of the Parana and Uruguay Rivers, is the natural ingress and egress to a hugh South American hinterland of 3,225,000 km2 covering the entire Republic of Paraguay, and parts of Argentina, Bolivia, Brazil, and Uruguay.1 This region, the De la Plata Basin, is today inhabited by approx- imately 60 million people, and the largest Latin American cities, Buenos Aires and Sao Paulo, are situated therein. According to the Papal Bull issued by Pope Alexander VI in 1493, both banks of the De la Plata River were Spanish, but first the Portuguese and later the Brazilians occupied the left bank and settled in the town of Colonia, located across the river from Buenos Aires.

  • 2020 Conservation Outlook Assessment
    IUCN World Heritage Outlook: https://worldheritageoutlook.iucn.org/ Iguazú National Park - 2020 Conservation Outlook Assessment Iguazú National Park 2020 Conservation Outlook Assessment SITE INFORMATION Country: Argentina Inscribed in: 1984 Criteria: (vii) (x) The semicircular waterfall at the heart of this site is some 80 m high and 2,700 m in diameter and is situated on a basaltic line spanning the border between Argentina and Brazil. Made up of many cascades producing vast sprays of water, it is one of the most spectacular waterfalls in the world. The surrounding subtropical rainforest has over 2,000 species of vascular plants and is home to the typical wildlife of the region: tapirs, giant anteaters, howler monkeys, ocelots, jaguars and caymans. © UNESCO SUMMARY 2020 Conservation Outlook Finalised on 02 Dec 2020 SIGNIFICANT CONCERN The natural beauty of the Iguazú waterfalls is being negatively impacted from unnatural changes in river levels due to the operation of dams on the upper Iguazú River. Concerns also remain regarding possible negative environmental effects of unnatural shifts in water levels due to the newly constructed Baixo Iguaçu dam close to the boundaries of Iguazu National Park, and Iguaçu National Park in Brazil. Protection and management of Iguazu National Park is mostly effective within its boundaries, especially considering the high rate of visitation and the increasing contribution of research and monitoring to management decisions. Studies conducted on the site’s biodiversity tend to indicate it is being maintained. However, the impacts of threats originating outside the area, including biological isolation due to agriculture and livestock grazing, roads, and upstream dams are considerable.

  • IGUAZÚ BIRDING TOUR, 20-24 Sep 2022
    1 | ITINERARY Iguazu Birding Tour THE GOLDEN GATE AUDUBON SOCIETY & bring you: IGUAZÚ BIRDING TOUR, 20-24 Sep 2022 Iguazu Waterfalls by Anne Koke www.birdingecotours.com [email protected] 2 | ITINERARY Iguazu Birding Tour Surrounded by Atlantic Forest bordering Brazil, Argentina and Paraguay, Iguazu Falls is one of the great natural wonders of the world. Here, where the Iguazu River tumbles over the edge of the Parana Plateau, is often considered the world’s most spectacular waterfall. Ever since the Spaniards discovered these falls in the 16th century, they have not ceased to impress travelers from all over the whole world, and a visit here can be considered as a once in a lifetime trip and one of the highlights of South America. The falls span over 1.6 miles (2.6 km) and are comprised of over 275 distinct falls, forming a breathtaking sight. Perhaps the most impressive is the U-shaped Devil’s Throat which is 250 feet (82 meter) high, 450 feet (150 m) wide and 2100 feet (700 m) long; this is the truly iconic waterfall of the park, immortalized in the iconic 1986 movie The Mission. Even though the waterfalls are shared by Brazil and Argentina, we advise spending the bulk of the time on the Argentinian side, which is what we focus on during this tour, using a super easy border crossing. The birding is best on the Argentinian side. During this 5-day tour, we shall have adequate time to admire the waterfalls as well as to look for the special birds.

  • Lack of Allocation Policies and Its Implications For
    ALLOCATION POLICIES AND ITS IMPLICATIONS FOR RECREATIONAL FISHERIES MANAGEMENT IN INLAND WATERS OF ARGENTINA Pablo H. Vigliano1, José Bechara2, Rolando Quiros3 1Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, Quintral 1250, (8400) Bariloche, Río Negro, Argentina. 2 Instituto de Ictiología del Nordeste, Facultad de Ciencias Veterinarias, UNNE, S. Cabral 2139, (3400) Corrientes, Argentina. 3Departamento de Producción Animal, Facultad de Agronomía, Universidad de Buenos Aires, Av San Martin 4453, (1417) Buenos Aires, Argentina. Abstract The Northeast, Central, Western and Northwestern, and Patagonia and Tierra del Fuego regions dominate Argentina inland recreational fishing. Being each unique in terms of environmental context, fish fauna and fishery types. High species diversity, extractive fishing and highly priced fly-fishing catch and release fisheries characterizes the Northeast. The Central Western and Northwestern fisheries are extractive, targeting few species. Patagonia and Tierra del Fuego have extractive and catch and release salmonid fisheries on the Andes. There are extractive fisheries of native species on Atlantic drainages of northern Patagonia, and anadromous rainbow and brown trout fisheries on southern Patagonia and Tierra del Fuego. In the Northeast, Central, Western and Northwestern regions conflicts between fisheries sectors (e.g. recreational vs. commercial) exist. In Patagonia and Tierra del Fuego conflicts within the recreational sector associated to fishery types and fisher philosophies (e.g. extractive vs. catch and release, highly price lodges vs. free access) predominate. Allocation, where implemented is set by specific interest groups not as part of an official strategy. This is part of a broader problem namely: lack of awareness of the fragility of the resource, which in term results in lack of integrated approaches towards the sustainability of Argentina’s inland recreational fisheries.
