Matt Bille: British conservationist and writer Debbie Martyr, aided by wildlife photographer Jeremy Holden and others, has pursued Sumatra’s orang-pendek (“short man”) or sedapa since 1989. She believes she has seen the animal herself and has collected footprint casts, unidentified hairs, and numerous eyewitness accounts of a primate something like a gibbon, but larger and habitually bipedal. While there is still no type specimen in hand, the search is quite “respectable” as cryptozoological quests go. No less an authority than the WWF's Dr. John MacKinnon once found what he believed were the animal's tracks, and Dr. Henry Gee of the journal Nature suggested the orang-pendek might be connected to the fossil discovery of diminutive humans on the island of Flores. Martyr's search for the orang-pendek has been necessarily sporadic, interrupted by events like the tsunami and the battle against illegal logging and other threats to Sumatra's remaining wild forests.Martyr's conservation efforts are funded by Flora and Fauna International (FFI). She and her colleagues are trying to preserve habitat for Sumatra's wildlife, especially the critically endangered Sumatran tiger (Panthera tigris sumatrae or Panthera sumatrae).
