- Text and images are not restricted, and their formats can be chosen as desired.

- Tables and lists are extracted as data, so the following restrictions apply to them:

−
   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.  
−
   2) Keyword 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.
−
   3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent
 
−
    to the relevant table or keyword list. This ensures that the same keyword always refers to the same concept, e.g. Everybody uses "Industrial mining",  
 
−
    rather than several keywords such as "Industrial mining", "Large-scale mining", and "Mining".

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).

Asia > Vietnam > Xuan Nha Nature Reserve

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.

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).
