Solutions:
Put all wild elephants on the endangered species list rather than just consider them a protected species. This will empower related authorities to prevent the commercial exploitation of elephant parts.
Prohibit all products made out of elephant parts, including ivory, skin, bone and all organs from both live and dead elephants regardless of elephant origin and the cause of death. This is to prevent fraudulent claims that parts are derived from domesticated elephants in and outside of the country. It is impossible to tell the difference between ivory derived from a wild elephant and a domesticated one.
Totally reform domesticated elephant registration from birth to death, with accurate identification - microchip plus DNA recording - to prevent registration fraud, especially with elephant calves. The conspicuous increase in domesticated elephants suggests there could be a number of wild elephant calves being posed as domestically born. For every fraudulent calf, there could have been as many as four foster mothers killed.
Declare all remaining forest land reserve forest and prohibit any unsustainable use of forest resources. Restrict further development in forest land. Any project that would effect the ecosystem must be prevented or revoked. There must exist the resolve to stop giving in to financial interests, local or national, when conservation is at risk.
Educate local populations about elephant conservation, the problems involved and the related laws. Wild elephants are sometime killed by villagers seeking valuable forest products or by plantation farmers on former elephant feeding grounds.
Strengthen law enforcement and forest rangers with authority to investigate conservation related cases and suppress crimes involving forest resources.
