A total of 106 cases of jumbo deaths have been reported across the state during the period and unreported deaths will take the toll higher, the Kerala-based Heritage Animal Task Force said.
Of the total wild elephants that died, 12 were male, 60 female, three 'makhnas' (tuskless male jumbos) and 10 calves, the statistics compiled by the outfit said.
However, the Kerala Forest Department officials said they can not confirm the figures as they are yet to compile a full-fledged data on the death of elephants this year.
"But, even if the total number of 85 wild elephant deaths is true, it is normal rate going by the total wild elephant stock of the state which is 6,177 as per the 2012 census," he said.
As far as Kerala is concerned, the mortality death of wild elephants up to two to three per cent is normal, he said.
