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.
|Range Description:||This species is an Eastern Arc endemic found in the Usambara and Udzungwa Mountains. There are also reports that it is found in the Uluguru Mountains. This species is found between 700 and 2,000 m above sea level. The area in which this species is distributed is approximately 15,161 km².|

|Population:||This species is known to be rare.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is restricted to montane rainforests. Emmrich (1997) reports that it is very difficult to breed this species in captivity.|
|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:||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.|
