Today is World Ranger Day where we remember all those courageous men and women around the world who put their lives on the line every day to protect our natural heritage.  I’ve been fortunate to go on patrol with local rangers and to witness them in action in Samburu and to spend time with them in Rwanda during a recent trip to photograph mountain gorillas. Here are some of my images of rangers from the Nasuulu conservancy and STE’s Security Liaison officer Chris Leadismo on patrol in Buffalo Springs and of rangers who work in the Virungas in Rwanda protecting the last remaining mountain gorillas . We salute you guys!
