Critically Endangered Species

ASG

+ Addax (Addax Nasomaculatus)

The Saharan bovid species at highest risk of extinction in the near future

 

Status justification: Listed as Critically Endangered as the species is believed to have undergone a decline well exceeding 80% over the past three generation (21 years). The total population is estimated at less than 300 individuals across the range, with the majority of the population in the Termit/Tin Toumma region of Niger. The population continues to decline due to ongoing threats of hunting and habitat loss.

+ Hirola (Beatragus hunteri)

One of the most highly threatened antelopes in Africa

 

Status justification: Given a conservative estimate of generation time at nine years, the 85 to 90% decline (and continuing) since 1980 has occurred over three generations and meets the thresholf for Critically Endangered under criterion A2, and on the basis of direct observation, decline in area of occupancy and habitat quality and levels of exploitation.

+ Ader's duiker (Cephalophus adersi)

The most highly threatened duiker in the world

 

Status justification: Listed as Critically Endangered as there has been an observed decline on Zanzibar from 5,000 individuals (1983), to 2,000 (1966) to 640 (1999). There are no recent population estimates, but on the basis that the known reasons for the decline are still occurring (i.e., a continued decline in the area and quality of habitat due to illegal wood-cutting, and the continuation of illegal hunting), it is suspected that the population will continue to decline at a similar rate.

+ Dama gazelle (Nanger dama)

The Dama Gazelle is following the same trail into extinction in the wild as the Scimitar-horned Oryx

 

Status justification: The sustained decline due to uncontrolled hunting and habitat loss has continued and is now estimated to have exceeded 80% over 10 years. Extensive field surveys have been made since 2001, but all subpopulations encountered are very small, with all at risk from unmanaged large-scale hunting, and the total population certainly numbers well less than 500 individuals. Decline is expected to continue base on ongoing hunting and unpredictable arrival of large hunting parties with high destructive potential from the Gulf states.

+ Saiga (Saiga tatarica)

The most highly threatened antelope in Asia

 

Status justification: The population has shown an observed decline of over 80% over the last 10 years and the decline is continuing. Severely skewed sex ratios are leading to reproductive collapse.
