Plants and Animals

Plants

Zanzibar is abundant with herbs, including large clove trees, henna and lemongrass. A large part of the island is covered with clove plantations and the rest is covered with tall palm trees.

The amount of forest is only a fraction of what used to be found there.

Animals

There are no large wild mammals on Zanzibar as there are on the Tanzanian mainland. The forested areas on Zanzibar are inhabited by monkeys and small antelopes. Civets and mongooses are found all over the island.

The number of bird species is very varied, with around 100 different species having been spotted. The marine life in the coral reefs is rich.

Mammels

Most of the original forests on Zanzibar are no longer there. As a result, the natural habitats on Zanzibar have been decimated; the best place to see wildlife is the Jozani Forest Reserve.

In this reserve, one of the most special animals is the Kirk's red (colobus) colobus monkey. It is one of the rarest monkey species in the whole of Africa and only occurs on Zanzibar. This species of monkey has only four fingers and no thumb; it is also the only primate with four stomachs to digest its food of hard leaves and unripe fruit. At present, there are only about 2,500 left on Zanzibar.

Another meerkat species is the blue meerkat or Sykes monkey.

Other mammals that occur on Zanzibar are the bush pig and the Zanzibar tree-clip-dace, Aders duiker (a small antelope species that occurs only on Zanzibar), and the Zanzibar suni, which is even smaller than the duiker.

An endemic subspecies of leopard, smaller and with finer markings than those on the mainland, is most likely no longer to be found on Zanzibar.

Small predators include the African and Javanese civet cat and several mongoose species; the Zanzibar slender mongoose, the rare bushy-tailed mongoose and the zebra mongoose, which was introduced to the island only later.

The large and small galago are nocturnal animals and both occur on Zanzibar. The large galago is as big as a rabbit, the small species is half as big.

There are also rats, mice, shrews and fourteen species of bat. The Zanzibar four-toed elephant shrew is special.

Reptiles and amphibians

The Aldabra giant tortoise is found, among others, on Prison Island, a few kilometres off the coast opposite Zanzibar Town. These animals were introduced from the Seychelles island of Aldabra in the 18th century.

The Jozani Reserve is also home to black and golden frogs, chameleons, snakes and geckos.

In the sea live the green turtle, the largest of the sea turtles, the loggerhead turtle, the hawksbill turtle, the dwarf turtle (last seen in 1975) and the leatherback turtle. All these turtles are endangered species.

Birds

Zanzibar is not known to birdwatchers as a true bird paradise, but there are about 220 species, both endemic and wintering. There are, however, several unique species. Since 1994, 35 new species have been discovered on the islands of the Zanzibar archipelago.

There are also remarkable differences between the birds on the main island of Unguja and the somewhat more northerly Pemba. Unguja has woodpeckers, clawed vultures, cuckoo vultures and buzzards, all birds that do not occur on Pemba. Pemba, on the other hand, has its own species of green pigeon, a dwarf owl, a spectacled bird and a honey bird that are found nowhere else in the world.
