<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
- Wiki pages contain information in paragraphs, tables, lists, and images.
- 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.
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.

Hukaung Valley Wildlife Sanctuary (HVWS), also known as Hukaung Tiger Reserve, is located in northwestern Myanmar. The site was established in 2001 and is currently in the tentative list for becoming a UNESCO World Heritage site. Due to its large size, connection to other protected areas, and diversity of forest types and elevations, HVWS contains a diverse assemblage of wildlife. HVWS includes many threatened and wide-ranging species such as the Asian Elephant, Tiger, and Rufous-necked Hornbill. The Hoolock Gibbon and Shortridge’s Langur are also present (UNESCO 2014).
