Cheetah research in diverse habitats

In such a vast area with a broad range of habitats, cheetah identification and monitoring can be challenging. In Tsavo, habitat is not primarily open plains and grassland, like in the Mara or Serengeti... An example is "Amri" a solitary male cheetah, who I just happened on, during a spoor tracking drive in the park. From previous sighting information, I knew I was in his, and other cheetahs', home range, but with thick bush, long grass and woodlands, these opportunistic sightings are not frequent enough..
