In 2016, the Kruger National Park detected possible Tuberculosis in their rhinos. Although this has not been completely verified, they required all rhinos going into rehabilitation from 2016 on to be isolated. As a result, the rhinos that came into the CFW sanctuary after 2016 – “Quarantine Rhinos” – could not go into the stronghold with the rhinos that came in before 2016, known as “Clean Rhinos”. The weaned Quarantine Rhinos also need extensive acreage to roam free. BRR donated the second stronghold, which enabled these rhinos to be released from their restricted lives and have real rhino lives in an area set aside for them.
