Why in News?

Odisha is set to unveil the world's first melanistic tiger safari near the Similipal Tiger Reserve (STR).

What is Odisha's Vision for the Melanistic Tiger Safari?

  • Melanism and Melanistic Tiger: Melanism is a genetic condition, that results in increased melanin production, leading to black or nearly black skin, feathers, or hair in animals.
    • The Royal Bengal Tigers of Similipal boast a distinctive lineage with elevated melanin levels, giving rise to black and yellow interspersed stripes, making them pseudo-melanistic.
  • Location of Safari: Spanning approximately 200 hectares near Dhanbad-Balasore National Highway-18, the safari site lies in close proximity to STR, providing a landscape akin to Simlipal.
    • In the beginning, three melanistic tigers from Nandankanan Zoo, along with rescued or orphaned tigers, will occupy the open enclosures of the safari.
  • Objective: It aims to raise awareness about the conservation needs of melanistic tigers, providing a platform for researchers and enthusiasts to engage with these rare big cats.
  • Approval: The project necessitates approvals from the Central Zoo Authority and other regulatory bodies overseeing wildlife initiatives in the country.

What are the Other Colour Variations in Tigers?

  • Orange with Black or Brown Stripes: This is the most common and widely recognized tiger coloration, e.g, the Royal Bengal Tiger.
    • Each tiger's stripe pattern is unique, serving as a form of camouflage, in their natural habitat.
  • White Tigers: They are not considered a separate subspecies. The colour of the white tiger's fur is the result of a genetic mutation called leucism.
    • Leucism is a genetic condition that results in reduced pigmentation in animals, causing them to have white or pale-colored skin, feathers, fur, or scales.
  • Golden Tigers: They are also not considered a subspecies of tigers because their golden colour variation is caused by the presence of a recessive gene called "wideband".
    • The wideband gene reduces melanin production during the cycle of hair growth.
    • Recently, it was spotted in Kaziranga National Park.

Similipal Tiger Reserve

  • Location: Similipal is situated in the Deccan Peninsula Biogeographic Zone.
  • Vegetation: Predominantly moist mixed deciduous forest with tropical semi-evergreen patches and sporadic dry deciduous forests and grasslands.
  • Floral Richness: Holds 7% of India's flowering plants and 8% of its orchid species.
  • Faunal Diversity: Home to 55 mammal species, 361 bird species, 62 reptile species, 21 amphibian species, and numerous insects and microfauna.
    • Major species other than tigers include sambar, chital, barking deer, gaur, and mouse deer, leopards, fishing cat etc.
    • Management efforts have revived mugger crocodile populations along rivers Khairi and Deo.
  • It has also been designated as a Global Network of Biospheres site since 2009.
