Assessment Information [top]

Red List Category & Criteria: Critically Endangered C2a(i) ver 3.1
Year Published: 2017
Date Assessed: 2016-08-07
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Hoffmann, M.
Contributor(s): Vaz Pinto, P.
Giant Sable is listed as Critically Endangered because the population is estimated to be well below the threshold of 250 mature individuals and no subpopulation contains more than 50 mature individuals. The Giant Sable faces several continuing threats including poaching and snaring and hybridization with roan antelope Hippotragus equinus has also occurred in recent years.

Population [top]

Population:There were an estimated 2,000-3,000 Giant Sable in the late 1960s (Estes and Estes 1974, East 1999). Numbers have since been greatly reduced and by 2007 were estimated at 200-400 (P. vaz Pinto in litt. to ASG, 2007). The decline has continued and there are now only ca 40 in Cangandala National Park and perhaps <50 in Luando Reserve (P. vaz Pinto, pers. comm. December 2015).
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:70-100Continuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Giant Sable prefers miombo woodland; it also occurs in low hills along the Cuanza River in Luando Reserve (Estes 2013).
Generation Length (years):7.1

Use and Trade [top]

Use and Trade: Giant Sable is subject to poaching for meat. Illegal capture and transport for wildlife ranching remains a constant threat, given the high price that any specimens would command.

Threats [top]

Major Threat(s): The survival of the Giant Sable through more than 20 years of civil war is highly encouraging, but its survival remains precarious as many Angolans who fled the Luando Reserve during the mid-1970s flood back to areas they had formerly evacuated. Poaching and snaring are ongoing in Luando Reserve. There have been recent incidents of hybridization of Giant Sable with Roan Antelope in Cangandala NP (Vaz Pinto 2006). Illegal capture and transport for wildlife ranching remains a constant threat, given the high price that any specimens would command.

Conservation Actions [top]

Conservation Actions: Luando Reserve and Cangandala National Park are the two essential strongholds for Giant Sable (East 1999). There have been calls for the establishment of a Giant Sable National Park to encompass both these protected areas (Walker 2002).

No individuals of Giant Sable are held in captivity. Giant Sable is listed on CITES Appendix I.
