Extant: Surviving compatriots of the dodo
By Fabiola Monty
The island of Mauritius is part of the Madagascar and the Indian Ocean Islands biodiversity hotspot. A high percentage of the Mauritian native flora and fauna are unique to its territory, with some species even being found only on small islets off its coast.
Following the first human settlement in early 17th century and increasing human activities on the island, a rapid loss and degradation of the pristine forests occurred. And today less than 2% of native forest remains.
Vaughan and Wiehe (1937) and Page and D’Argent (1997))
Deforestation combined with the introduction of non-native animals and plants have contributed to the demise of many unique species alongside the famous dodo.
Despite the numerous species lost and current high level of endangerment particularly for the native flora , Mauritian biodiversity have high conservation value and holds several treasures constituting the country’s natural heritage.
So meet five extant (i.e. still existing) representatives of different groups of our native flora and fauna
1. PLANTS
As of 2013, 691 native species of flowering plants were recorded for Mauritius. Of these 39.5 % were documented as being Mauritian endemic (i.e. found only in Mauritius). Through the work of The Mauritius Herbarium and the University of Mauritius, this list is being updated as new species are described, rediscovered after being though to be extinct and more informaton are gathered on the geographical range of some species.
2. BATS
Bats are the only native mammals found in Mauritius. Five species of native bats used to coexist on mainland Mauritius. One of these species, the Rodrigues Flying Fox is now locally extinct and as the name implies, it is now restricted to Rodrigues island, some 560 Km east of Mauritius. The Lesser Mascarene Flying-fox (Pteropus subniger) is on the other hand, a species that is now gone forever. Remaining native bat species in Mauritius include two insectivorous bats and the Mauritian flying fox also known as the Mauritius fruit bat.
3. BIRDS
Mauritian endemic birds are probably the most globally known component of Mauritian biodiversity. After all, the flightless dodo is the global symbol of extinction. Species like the Mauritius Kestrel, the Pink Pigeon and the Echo Parakeet were at the brink of extinction several decades ago, but showed important population recovery following intensive species management.
4. SNAILS
Native invertebrates are probably the underdog species when it comes to conservation. Similarly to other native species, land snail fauna has suffered dramatic decline due to habitat loss and alteration and the introduction of non-native species. In comparison to the other islands in the Mascarenes (Reunion and Rodrigues), Mauritius is documented to have the greatest number of endemic land snails and also the highest extinction rate (Griffiths and Florens, 2006).
5. REPTILES
Habitat loss and the introduction of animals like rats in Mauritius contributed to the loss of Mauritian endemic reptile species and populations. Several species such as the Round Island boa, the Telfair’s skink and the Round Island day gecko are now restricted to offshore islets.
