“It’s a surprising finding,” Dr. Vogel told mongabay.com, “as [the new species] is a large viper, very colorful and superficially different.” It inhabits forested areas between 1,500 and 2,000 meters (5,000 to 6,500 feet) in elevation. This is an important difference from T. sumatranus, which lives on lower, hilly areas rarely above 950 meters (3,000 feet).The difficulty in accessing these high mountain areas, as well as lack of economic interest in developing them, has preserved them from deforestation, according to a 2011 study in Global Change Biology.

“This is a highland species and in Sumatra there is little infrastructure in the higher mountain areas, so I feel it might be safe in the near future,” Vogel said. However, he cautioned its safety is far from secure, saying that its distribution should be more thoroughly studied to help further understanding of the species and its long-term prognosis. He added the region itself deserves more attention, with more endemics possibly awaiting scientific discovery. Vogel, who has discovered other reptile species, is a freelance herpetologist as well as a chemist whose research is self-funded and not tied to any particular institution. For their study, the researchers inspected 53 specimens of T. sumatranus and Trimeresurus hageni, with the primary objective of establishing the differences between them and amend the historical confusion of these two species.
