[1] Mount Pueh was known to biologists for the collections made there by Eric Mjöberg (1882–1938), a Swedish naturalist, who was Curator of the Sarawak Museum between 1922 and 1924.
[2] Mjöberg's herpetological collections from Gunung Pueh between October and December 1923, and other localities in Borneo, were reported by Smith (1925).
The only montane endemic recorded in this expedition is the grey fruit bat, Aethalops alecto.
Based on their tracks and other signs, wild pigs (Sus barbatus) were common near the summit.
Three arcuate horseshoe bats (Rhinolophus arcuatus), previously recorded only from Bungoh cave near Bau in Sarawak.
