Morne Diablotin National Park protects two endemic parrots and some of Dominica's least disturbed stands of old-growth tropical rainforests. Morne Diablotin is the highest mountain on the Caribbean island and the second highest in the Lesser Antilles.
Morne Diablotin National Park
Morne Diablotin National Park was established in January 2000 and covers 3,335 ha (8,242 acres). It was created from lands formerly part of the Northern Forest Reserve and the Syndicate Parrot Preserve.
The primary function of the National Park is to provide habitat for Dominica's two endemic Amazona parrots. In addition, the Syndicate Nature Trail and the surrounding area in the Park have become the prime area for bird-watching in Dominica.
Morne Diablotin National Park protects some of the finest and least disturbed stands of tropical rainforest on the island and the insular Caribbean. The National Park also contains elfin woodlands, montane forests, and secondary rainforests.
The National Park also protects the headwaters of several rivers that flow through the island's northern half and provide potable water for the communities in the north, northeast and northwest parts.
Private lands are located mainly on the Park's north, northwestern and southwestern boundaries and are used strictly for agricultural holdings. Human settlements are more than 6 mi (10 km) away in the western coastal region.
In 2015, Morne Diablotin National Park was added to the UNESCO World Heritage Tentative List due to its universal natural significance.
Morne Diablotin (or Morne Diablotins), peaking at 1,447 m (4,747 ft), is the highest mountain in Dominica and the second highest in the Lesser Antilles after La Grande Soufrière in Guadeloupe. It is named after the Dominican Creole word for the Black-capped Petrel.
Morne Diablotin is located in the northern interior of the island, about 15 mi (24 km) north of Dominica's capital Roseau and approximately 6 mi (9.6 km) southeast of Portsmouth, the island's second-largest town. It is located within Morne Diablotin National Park.
The stratovolcano consists of at least five coalescing lava domes that form the broad summit. Additional domes are found to the southeast.
No historical eruptions are documented, although numerous onshore and submarine hot springs are found near Glanvillia on the northwest flank. Severe earthquake swarms in 1841 and 1893 originated from Morne Diablotin or Morne aux Diables to the north.
Pyroclastic-flow deposits emplaced around 22,000 - 40,000 years ago, known as the Grand Savanne Ignimbrite, extend in five radial tongues around the volcano as far as the coast. In addition, pre-Columbian block-and-ash flow aprons on the northwest flank are relatively unmodified by erosion.
Morne Diablotin National Park is home to two species of Dominican parrots found nowhere else in the world.
- imperial amazon (Amazona imperialis) or Dominican amazon, also known as the sisserou or sisserou parrot: Conservation Status "Critically Endangered"
- red-necked amazon (Amazona arausiaca) or red-necked parrot, also known as the Jaco parrot, Dominican blue-faced amazon or lesser Dominican amazon: Conservation Status "Vulnerable"
The imperial amazon, or Dominican amazon, has been designated as the national bird of Dominica and appears on the national flag. It inhabits mountain forest areas above 2,100 ft (625 m). The species frequently occurs on the Morne Diablotin, especially the upper Picard River Valley on the mountain's northwest side.
The Imperial Amazon is a critically endangered species. Significant causes of population decline have been hurricanes and habitat loss. There are estimated to be only about 50 mature individuals left in the wild as of 2019. A small population has been reintroduced into the Morne Trois Pitons National Park.
The most common migrant bird species found here include the black-throated blue warbler (Dendroica caerulescens), the hooded warbler (Wilsonia citrine), the black-and-white warbler (Mniotilta varia), and the merlin (Falco columbarius).
In addition, the plumbeous warbler (Setophaga plumbea) and the blue-headed hummingbird (Riccordia bicolor) are only found in Dominica and Martinique.
The more frequently seen waterbirds include the little blue heron (Egretta caerulea) and the yellow-crowned night heron (Nycticorax violaceus).
The dominant vegetation of the National Park includes:
- large buttressed trees
- prop-rooted trees with diameters of 1.8 m (6 ft) and above
- trees with stems covered with climbers
- wild anthuriums
- mosses and other epiphytes
Fauna species within the National Park include Feral Pigs (Sus scrofa), several species of bats, Agouti (Dasyprocta leporine) and Opossum (Didelphys marsupialis insularis).
Reptiles include the Boa Constrictor (Constrictor constrictor nebulosis), the Lesser Antillean Iguana (Iguana delacatissima), the Tree Lizard (Anolis oculatus), the pigmy gecko (Sphaerodactylus vincenti), and other lizard species, the Dominican tink frog (Eleutherodactylus amplinympha). In addition, the National Park provides habitat for several species of freshwater fish and crustaceans.
