= Site characteristics =

Designated as a nature reserve (Cagar Alam) in 1981, later reaffirmed as a wildlife sanctuary and then nature reserve again, Gunung Nyiut spans approximately 124,500 ha across Bengkayang, Landak, and Sanggau regencies in West Kalimantan, Indonesia. The reserve encompasses a rugged, forested volcanic massif rising to around 1,700 m above sea level ([[#R00710|Seksi Konservasi Wilayah III Singkawang 2014]]).
