There are more number of elephants who are outside our present day Protected Areas. You may refer to an excellent article which was posted earlier by Vikram Nanjappa.

Though elephant has been acknowledged as the National Heritage animal, there has been hardly any funds available for securing the migration path and the areas used by elephants that fall outside our present day Protected Areas.

Watching these majestic and intelligent animals moving around and going about their day to day chores is always a delight. Often I am amazed at the manner in which these elephants wait silently on the road side for a lull in the traffic to cross over. If we can have even one percent of their patience and understanding than the road rage cases will vanish.
