Leucism in Gaurs- a cause of concern!


Recently with the help of World Wide Fund India has carried out  an estimation exercise of Indian Gaur in the Nilgris forest division of Tamil Nadu. This is the first estimation exercise being held in region. According to the exercise, there are around 2,000 Gaurs across the division.


  • Accroding to the report of the exercise,the animals in the region are prone to human-animal conflicts due to habitat loss and fragmentation.
  • The Indian Gaurs in the region, specifically are inhabiting tea estates and human settlements.
  • The Gaurs are also affected by the invasive spread of the invasive species of plants in the reserve forest.
  • An increase in resorts and buildings in the region has led to erection of fences that limit the traditional pathways used by the Gaurs to move between the habitats.

About Indian Gaurs

  • The IUCN Red List has put the Indian Gaurs under Vulnerable category.
  • The Wild Life Protection Act, 1972 has put the Indian Gaurs under Schedule I.

Mutation in Indian Gaur:

  • The scientists have found that a rare genetic condition of leucism is observed in Indian Gaurs.
  •  Leucism causes partial loss of pigmentation in the skin pattern of the animal.
  • This is not good for the animals as leucism might compromise the immune system of the animals and reduce their survival rates.
  • The mutation is caused due to low quality diet, environmental alterations, follicular damage, in-breeding, pollution, etc.
