Livestock farmers, especially Maasai herdsmen, track and kill lions to avenge the loss of animals, threatening the existence of 35 to 40 lions at the park on the outskirts of the Kenyan capital.
Spokesman Paul Muya of the Kenya Wildlife Service, said Monday rangers will be able to move to areas where the lion have encroached using coordinates sent by the collars and return the animals to the park. The collars send GPS coordinates by text messages to a rangers' cell phones.
Two lions were fitted with collars Saturday, Muya said. Collars will be fitted to 10 lions from different prides.
