Réunion National Park (French: Parc national de La Réunion) is a National Park of France located on the island of Réunion, an overseas department in the western Indian Ocean. Established on 5 March 2007, the park protects the endemic ecosystems of Les Hauts, Réunion's mountainous interior, and covers around 42% of the island. Notable endemic species include the Réunion cuckooshrike and the Reunion Island day gecko.
Plans for a park date back to 1985, and in a public survey in 2004, the communes of Réunion approved the creation of a national park. It officially came into existence in 2007. The park's volcanic landscape, including the Piton de la Fournaise, an active volcano, was designated a World Heritage site in 2010, under the name "Pitons, cirques and remparts of Reunion Island". The park's mission, other than preserving landscape and biodiversity, is to share knowledge and welcome visitors, and to work together with local communes. It is a popular destination for hiking and mountaineering.
Controversies have emerged over economic development in the park, notably the exploitation of geothermal power. In 2016, the Regional Council of Réunion had plans to downgrade the national park to a regional nature park to ease tourism development. This was contested by the park authorities and opposition politicians.
Proposals to create a park were first raised beginning in 1985. The Réunion Environmental Charter and the Regional Development Plan formally established the principle that a park should be created in Les Hauts, the mountainous interior of the island. The French Ministry of the Environment was officially consulted for the creation of a national park.Between 2000 and 2003, a consultation process was launched, in which the state, the region, the département, and the association of mayors agreed on a protocol and established a steering committee. 27 of 29 institutions endorsed the plan of establishing a national park, and on 29 March 2003, the French Prime Minister signed a decree acknowledging the project.Debates and negotiations on the limits and objectives of the future national park intensified. Between August and September 2004, the plan was the subject of a public survey, organised by the prefect in the 24 communes of the island. The communes responded positively to the project, adding some recommendations.The park officially came into existence on 5 March 2007 through a decree taken after advice by the Council of State. In April 2007, the Administration Council took office; between 2007 and 2009, personnel were employed and installations made on the site. In 2008, work began to set up the charter of the national park.On 1 August 2010, the UNESCO World Heritage Committee acknowledged the value of the natural sites within Réunion National Park, and included the "Pitons, cirques and remparts of Réunion Island" in its World Heritage list.
In its charter, the national park identifies four main objectives: First, to preserve the diversity of landscapes and accompany their evolution. Second, to inverse the loss of biodiversity. Third, to preserve and add value to the culture of the highlands and ensure the transmission of its values. Fourth, to foster economic development for the highland.: 3
The core of Réunion National Park covers 1,053.84 km2 (406.89 sq mi) in the interior of the island, corresponding to 42% of its surface and extending over the land of 23 communes. This core area also includes some inhabited and cultivated land. Adjacent to the core is an area of voluntary commitment (aire d'adhésion, buffer zone) covering 876.96 km2 (338.60 sq mi) and touching all 24 communes on the island. Altogether, the park extends over more than 75% of the island.: 12 The island of Réunion is volcanic in origin and sits over a hotspot. Two volcanoes form its backbone: The Piton des Neiges, over 3,000 m (9,800 ft) high, and the still active Piton de la Fournaise.
Four major areas form the heart of the national park, listed as World Heritage site:
Mare Longue forest at Saint-Philippe, including some of the best-preserved remains of low-altitude tropical forest, termed Forêt de bois de couleurs des Bas;
the Cirque de Cilaos with the Pain de Sucre and La chapelle rock formations, in the narrow gorge of the Bras Rouge River, and 100,000-year-old accessible magma chamber;
the Cirque de Salazie with the Piton d'Anchaing, a 1,356 m (4,449 ft) high dominant massif;
La Grande Chaloupe between Saint-Denis and La Possession, one of the last remainders of the semi-evergreen forest once common in the west of the island, preserved and restored here.
Réunion shares a common natural history with the other Mascarene Islands, Mauritius and Rodrigues. All three islands were uninhabited before the 1600s. Human arrival led to massive extinction and introduced species, such as giant land snails in Réunion, which threatened native habitats and species. Less than 25% of Réunion is thought to be covered with original vegetation according to the World Wildlife Fund (WWF), mostly restricted to higher altitudes. The forests of Réunion and the other two islands have been classified as the "Mascarene forests" ecoregion by the WWF, with a conservation status of "endangered". Conservation International includes Réunion in the "Madagascar and Indian Ocean Islands" biodiversity hotspot, a priority area for conservation.
The isolation of the island and its diversity of habitats and microclimates have favoured the diversification of a highly endemic flora: Of the 850 known native plant species, 230 are endemic, and half of those are endangered. This native flora is found at various altitudes. Nearly as many exotic plants as native ones, 830, have become naturalised on the island, and 50 are considered invasive, threatening native flora and habitats.The park's fauna includes notably several endemic bird species, such as Barau's petrel, the Réunion harrier, and the Réunion cuckooshrike. In total, 18 bird species are found at Réunion, half of which are endemic. At least 22 bird species have already gone extinct since human colonisation. A major threat to the bird fauna are introduced cats and rats. Of mammals, the Mauritian flying fox recolonised the Réunion after going extinct from the island. Notable butterfly species include Papilio phorbanta and Salamis augustina, and an endemic reptile is the Reunion Island day gecko.
