Question: What park is the fifth largest in Spain's national parks system, Teide National Park or Guadarrama National Park?
Context: The United States has 59 protected areas known as National Parks that are operated by the National Park Service, an agency of the Department of the Interior.  National Parks must be established by an act of the United States Congress.  A bill creating the first National Park, Yellowstone, was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks), Sequoia and Yosemite in 1890.  The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."  Many current National Parks had been previously protected as National Monuments by the President under the Antiquities Act before being upgraded by Congress.  Seven National Parks (including six in Alaska) are paired with a National Preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below. Many areas of Vietnam are under protection.  While the national reserves cover small areas of scientific significance with restricted access, the national parks also cover wetlands of Ramsar designated areas and BirdLife International inscribed bird areas.  The largest of the national parks initially covered were the Cúc Phương National Park, the Cát Tiên National Park, and the Côn Đảo National Park which to start with were forest areas cum reserves or prohibited areas.  The objective for creating national parks was to allow access to the reserved areas as a part of ecotourism and cultural needs with full attention to the basic approach of conservation of natural environmental resources. Sierra de Guadarrama National Park (in Spanish: "Parque Nacional de la Sierra de Guadarrama") is a national park in Spain, covering nearly 34,000 hectares, the fifth largest in Spain's national parks system.  The Guadarrama mountain range ("Sistema Central") contains some ecologically valuable areas, located in the Community of Madrid and Castile and León (provinces of Segovia and Ávila).  The law that regulates the recently approved national park was published in the BOE in  26, 2013 (2013--) . Within England and Wales there are thirteen areas known as national parks, each administered by its own national park authority, a special purpose local authority, the role of which as set out in the Environment Act 1995 is: "to conserve and enhance the natural beauty, wildlife and cultural heritage of the National Parks."  and "to promote opportunities for the understanding and enjoyment of the special qualities of the National Parks by the public."  The national park authority for each park addresses these aims in partnership with other organisations, such as the National Trust.  In cases where there may be conflict between the two purposes of designation, the first must take precedence under the Sandford Principle.  The national park authorities also have a duty to foster the economic and social wellbeing of communities in pursuit of these purposes. Malkumba-Coongie Lakes National Park is a protected area located in the north-east of South Australia about 110 km north-west of Innamincka.  The national park was proclaimed on 31 March 2005 as the Coongie Lakes National Park under "National Parks and Wildlife Act 1972" over a parcel of land previously part of the Innamincka Regional Reserve to "conserve significant wetlands, provide experiences for visitors and ensure that the core component of the Coongie Lakes system was protected."  The national park is located on land that was included on the List of Wetlands of International Importance under the Ramsar Convention under the name, Coongie Lakes in 1987.  In 2014, the national park was renamed as the Malkumba-Coongie Lakes National Park.  The national park is co-managed by the Department of Environment, Water and Natural Resources (DEWNR), the Yandruwandha Yawarrawarrka Parks Advisory Committee and South Australian Arid Lands Natural Resources Management Board.  It is classified as an IUCN Category II protected area. The national parks of New Zealand are 13 protected areas administered by the Department of Conservation.  Although the national parks contain some of New Zealand's most beautiful scenery, the first few established were all focused on mountain scenery.  Since the 1980s the focus has been on developing a more diverse representation of New Zealand landscapes.  The parks are all culturally significant; many also contain historic features.  Tongariro National Park, in particular, is one of 27 World Heritage Sites that is of both cultural and natural significance, while four of the South Island national parks form Te Wahipounamu, another World Heritage Site.  A 14th national park, Te Urewera National Park, was disestablished in 2014. A Year in the Wild is a 2012 British nature documentary series about the country's national parks.  Produced by the BBC, the series is narrated by actress Hermione Norris.  It consists of three episodes, each an hour long.  The first episode, "Snowdonia", premiered on 27 July 2012 and features Snowdonia National Park.  Snowdonia is located in Wales, and is known for its hills and extinct volcanoes.  The second episode, "The New Forest", premiered on 3 August 2012.  The episode explores the fauna of the New Forest National Park.  The Park, located in southern England, was established in 2005 and is one of the country's newest national parks.  The final episode of the series, "Cairngorms", premiered on 10 August 2012.  The Cairngorms National Park covers the Cairngorms mountain range in Scotland, and is Britain's largest national park, with an area of 4,528 km2.  All three episodes describe the wildlife of each park, the ecosystem, and the people who live near, work, or frequent the parks. Teide National Park (Spanish: "Parque nacional del Teide" , ] ) is a national park located in Tenerife (Canary Islands, Spain). Kejimkujik National Park (often called Keji for short) is part of the Canadian National Parks system, located in the province of Nova Scotia.  The park consists of two separate properties: the main park is located in the upland interior of the Nova Scotia peninsula bordering Queens and Annapolis counties; and the smaller Kejimkujik Seaside unit, located on the Atlantic coast of Queens County.  The park covers 404 km2 .  The inland unit is designated a National Historic Site of Canada, making Kejimkujik unique in the park system as the only national park whose virtually entire area is a National Historic Site. The National Parks of Argentina make up a network of 33 national parks in Argentina.  The parks cover a very varied set of terrains and biotopes, from Baritú National Park on the northern border with Bolivia to Tierra del Fuego National Park in the far south of the continent.  The Administración de Parques Nacionales (National Parks Administration) is the agency that preserves and manages these national parks along with Natural monuments and National Reserves within the country.
