No White Lions currently roam freely! They were first spotted by Europeans in 1938 and documented later in 1970's, though African records (stories and traditions) indicate they were resident in this region for much longer. There were 12 recorded births in 9 prides in the Timbavati and Kruger National Park between 1975 and 1980. Due to the artificial removals in Timbavati and the lion culling in KNP in the 1970's, there have less than a handful of births from 1980 to 2006. It is hard to determine exactly how many white lions there are today, because they are held in captive breeding and canned hunting operations which don't keep adequate records. Based on available evidence, there are an estimated 300 White Lions world-wide. None are in their natural distribution range, except those in environmental projects where they roam in semi-natural enclosures.
