UNITED NEWS INTERNATIONAL (UNI) – Eight endangered black rhinos have died from salt poisoning in Kenya.

The country’s Ministry of Tourism said in a statement on July 13, the rhinos were relocated to Tsavo East National park in an effort to begin a new population.

However, according to a preliminary investigation by Kenya Wildlife Service, saltwater levels at the new home were too high for some of the rhinos to tolerate.

The Ministry of Tourism said it is a challenge for rhinos to transfer from fresh water to saline water in a sanctuary. The high salt leads to dehydration, so the animals drink more which elevates the problem.

Eight out of eleven relocated rhinos died. The remaining three are being monitored closely.

Fourteen rhinos were supposed to be relocated in total, but following the deaths, that has been put on hold.
