Forty-three rhinos have been identified in the census, conducted by biodiversity conservation organisation 'Aaranyak', through genetic analysis of dung samples, the organisation's head of Wildlife Genetics Programme, Udayan Borthakur, said.
"These results are significant as according to the 2012 rhino census, conducted by the Forest Department using the conventional methods, there were 42 rhinos in the Park," Borthakur said.
Moreover, the study confirms a sex ratio 4:1 (male: female) similar to what has been found earlier and this skewed sex ratio with more number of males has been a matter of concern for the authorities, he said.
The project was undertaken with the permission and support from the West Bengal Forest Department to which Aaranyak has already submitted the report recommending further genetic study on rhinos in the particular sanctuary as well as the Jaldapara Wildlife Sanctuary, both in Jalpaiguri district.
Borthakur, who is also a member of the IUCN SSC Asian Rhino Specialist Group, pointed out that the genetic diversity in the Gorumara rhino population is low, which necessitates management intervention to ensure long term survival.
"This is an important methodological development in the field of rhino research, which may greatly contribute towards scientific management of rhinos populations in India. MORE
