Volcanoes and Forests of Mount Pelée and the Pitons of Northern Martinique: A Unique Blend of Geological Wonders and Biodiversity

Mount Pelée, located at the northern tip of Martinique, is an exceptional example of a volcanic landscape that has been shaped by geological forces over millennia. This active volcano, officially known as Mont Pelée, is part of the Lesser Antilles Volcanic Arc, a chain of islands and volcanoes in the Caribbean. The Volcanoes and Forests of Mount Pelée and the Pitons of Northern Martinique were inscribed as a UNESCO World Heritage Site in 2023, recognizing their unique combination of volcanic features and diverse forests.

UNESCO Description of the World Heritage Site

The global significance of Mount Pelée and Pitons du Carbet is based on its representation of volcanic processes and forest types. The 1902 eruption is considered the deadliest volcanic event of the 20th century, and a worldwide reference for the history of volcanology. All the forest types and the diversity of endemic plants of the Lesser Antilles are represented in the serial property, within forest continuums ranging from the seashore to the volcanic summits. The property is home to globally threatened species such as the Martinique Volcano Frog (Allobates chalcopis) and the Martinique Oriole (Icterus bonana), two strict endemics.

UNESCO Justification of the World Heritage Site

Criterion (viii): The Pitons du Carbet and Mount Pelée are remarkable illustrations of the volcanic morphologies and mechanisms characteristic of the Lesser Antilles island arc. The Pitons du Carbet, in particular, consist of highly elevated lava domes, a result of the great viscosity of the magmas from which they were formed. The scar from the flank destabilisation that enabled their development is the largest in the Lesser Antilles archipelago. There are twelve of these formations, five of which exceed 1,000 metres in altitude, making them the most representative examples of this geological phenomenon, which is otherwise only observed in Saint Lucia. The highest, the Piton Lacroix, reaches 1,197 metres, making it the highest in the world for the geological process from which it originated. An iconic volcano, Mount Pelée features a unique eruptive type: the lava dome with laterally directed explosions, notable for the frequency of its past eruptions. The eruption episode of Mount Pelée from 1902 to 1905 was particularly significant. In fact, the pyroclastic flow on May 8, 1902, led to the death of 28,000 people in the minutes following the explosion. In an extremely rare occurrence, during the 1902 eruption, 7 successive explosions took place, resulting in the formation of a 350-metre-high needle, the tallest known to have formed during any dome eruption. This eruption is a global reference in the history of volcanology, as it helped describe one of the major types of volcanic eruptions: the Pelean type. The site remains, to this day, a key location for the study of Earth sciences.

Criterion (x): The property is located within a globally recognised priority biodiversity conservation area: the “Caribbean Islands” biodiversity hotspot. It hosts the most diverse and well-preserved forest continuum in the Lesser Antilles. This vegetation cover is characterised by the quality and completeness of the forest successions, which encompass all the forest types native to Martinique and the Lesser Antilles. In the heart of the north-western slopes of the Piton Mount Conil massif, on the lower slopes of Pain de Sucre, and on the reliefs of Morne Jacob, undisturbed climax vegetation formations are preserved, particularly mesophilic and hygrophilic forest types. The property is home to an exceptional flora comprising 1,058 species of native vascular plants, including 816 spermatophytes and 242 pteridophytes. Among these, 51 species are threatened, such as the Calumet Montagne, the Fleur-Boule-Montagne, and the Aralie. The property provides a critical habitat to ensure their long-term conservation. The flora of the property is representative of the rich plant diversity of the Lesser Antilles and exhibits a high rate of regional endemism. There are 263 species of regionally endemic spermatophytes (Lesser Antilles), of which Martinique alone is home to 186 species, representing 71%. The island also features the most significant and representative strict endemism in spermatophytes within the Lesser Antilles, with 37 of the 104 species found along the arc. The property is home to 33 of these endemic species, accounting for one-third of the strictly endemic species of an island within the Lesser Antilles. These include: the wild pineapple, the bwa débas blan and krékré wouj. Their presence is sometimes limited to a few locations within a single entity of the property. The tree flora is also particularly rich, representing 87% of the tree flora of the Lesser Antilles (i.e., 401 species). The animal biodiversity further enriches the property, as it is home to numerous remarkable and endemic species, such as the Martinique volcano frog, the Martinique bat, the Martinique lancehead, and the Martinique oriole.

Encyclopedia Record: Mount Pelée

Mount Pelée or Mont Pelée is an active volcano at the northern end of Martinique, an island and French overseas department in the Lesser Antilles Volcanic Arc of the Caribbean. Its volcanic cone is composed of stratified layers of hardened ash and solidified lava. Its most recent eruption was in 1932.
