Mauritius

África

Mauritius is a volcanic island in the Indian Ocean ringed by an almost continuous coral barrier, with an interior of plateaus, steep peaks and gorges. Its natural history is one of the most dramatic on the planet: when the Europeans arrived in the sixteenth century, the island was covered in endemic forest and inhabited by a fauna with no fear of human beings, which disappeared within a few decades through hunting and through the rats, pigs and monkeys that were introduced. The dodo, a giant flightless pigeon, became extinct barely a century after its discovery and turned into the universal symbol of extinction. Today fragments of native forest survive in Black River Gorges and on satellite islets that work as arks, where the original vegetation and fauna have been rebuilt step by step.

The nature of Mauritius

National animal: The dodo, an extinct bird and the national emblem, present on the country's coat of arms

Did you know?

In 1974 only four Mauritius kestrels were known to be alive in the whole world, which made it the rarest bird on the planet. A captive breeding programme that collected the eggs to incubate them and prompted the females to lay again managed to multiply the population to several hundred birds in the wild. It is one of the most extreme recoveries in the history of conservation.

Flagship wildlife

Notable endemic species

  • 39% de las plantas, 80% de las aves no marinas, 80% de los reptiles y 40% de los murcielagos son endemicos de Mauricio
  • Mas de 700 especies vegetales endemicas registradas

  • Paloma rosada
  • Cotorra de Mauricio
  • Zorro volador de Mauricio
  • Boa de Round Island

Notable threatened species

  • Dodo (extinto, eliminado pocos años despues de la llegada de los primeros colonos, icono mundial de la extincion causada por el ser humano)
  • Cernicalo de Mauricio y paloma rosa (ambos recuperados de poblaciones criticamente bajas mediante programas intensivos de cria en cautividad)
  • 141 especies de plantas con flor catalogadas En Peligro Critico

Notable protected areas

  • Parque Nacional de las Gargantas Negras (mayor remanente de bosque nativo)
  • Isla Redonda (santuario de restauracion ecologica)
  • Parque Nacional de Black River Gorges
  • Isla de los Aigrettes
  • Parque Marino de Blue Bay
  • Isla de los Ciervos
  • Reserva de Bras d'Eau

Main conservation threats

  • Perdida historica extrema de habitat nativo (solo 2% de bosque original remanente)
  • Especies invasoras, principal amenaza continua para la fauna endemica superviviente
  • Cambio climatico y ciclones tropicales recurrentes

Notable natural phenomena

  • El caso del dodo, extinto pocas decadas despues de la llegada humana a la isla, es el ejemplo mas citado a nivel mundial de extincion antropogenica insular; en contraste, el cernicalo de Mauricio y la paloma rosa son considerados exitos emblematicos de recuperacion de especies desde poblaciones criticamente bajas

Conservation

Mauritius is a world reference in island restoration: invasive species have been eradicated from several islets and plants, birds and reptiles have been reintroduced, even using Aldabra giant tortoises as ecological substitutes for the island's extinct tortoises.

Where and when to watch wildlife

Black River Gorges year-round for endemic birds. Île aux Aigrettes for giant tortoises and restored forest. The western waters between July and October for humpback whales.
