  1) Table structure cannot be changed.

  2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.

  3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

No signs of gibbons were recorded during a ten day survey in 2011, but there were reports of gibbons in the buffer zone (Nguyen Manh Ha et al. 2011), which may be the gibbons in Long Luong Commune (Rawson et al. 2011). During mammal surveys conducted between 2006 and 2010, gibbons were not detected either, but interviews with local residents suggest that some gibbons persist within and outside the reserve (Rawson et al. 2011).

Summary

Loading map...
  • Northern white-cheeked gibbons (Nomascus leucogenys) are present in Xuan Nha Nature Reserve.
  • Gibbons may be absent in the reserve, or occurring at very low densities.
  • The site has a total size of 163.17 km².
  • Key threats to gibbons are hunting and shifting agriculture leading to habitat loss.
  • Conservation activities are not documented.
