Did you know?

  • Almost 200 000 once roamed the north but by the early 1900s their numbers had plummeted to fewer than 300.
  • An intensive recovery program since 1980 has brought their numbers up to approximately 4500 but bovine diseases, brucellosis and tuberculosis remains a major obstacle to further recovery.
