Atheris ceratophora has been assessed as Vulnerable owing to its restricted range, severely fragmented population and a continuing decline in habitat quality. This species has an extent of occurrence of approximately 15,000 km² and is only found within montane rainforest, in an area where deforestation is prevalent.

Threats [top]

Major Threat(s): This species is found within a fragmented habitat that is threatened by high rates of degradation and deforestation, due to agriculture, logging and increasing human population.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for this species. It is found within the Udzungwa Forest National Park and Mazumbai Forest Reserve. Efforts to reduce further habitat loss are required (i.e. protected areas). Population and habitat research and population monitoring are necessary to establish the effects that a fragmented, disturbed environment is having on the population size of the species.
