Rationale (Changed due to Same category but change in criteria)

Samingo Monkey is endemic to South Africa. Cercopithecus mitis labiatus is found in discrete forest areas with little to no dispersal between subpopulations. It is listed as Vulnerable on the basis of a suspected past decline exceeding 30% over the past three generations (which is exacerbated by a suspected ongoing decline in the species over the past 150 years), mainly due to the loss of suitable habitat throughout the subspecies' highly fragmented range because of past logging practices, slash and burn clearing for agriculture and the encroachment of commercial forestry plantations. It is estimated that the core area of occupancy for the species is approximately 870 km², as measured by area of intact forest patches.

Distribution

This subspecies is distributed in isolated Afrotemperate and Afromontane forest patches from the Pirie Forest in the Eastern Cape Province north-eastwards through the midlands of the KwaZulu-Natal Province (South Africa) to the escarpment forests of Mpumalanga Province, and possibly Limpopo Province, as far north as the Soutpansberg, where they may be recognised as C. m. schwarzi or C. m. erythrarchus (Lawes 1990, Lawes et al. 2013). Genetically indistinguishable subpopulations have also been identified in the southern Indian Ocean coastal forests near East London and along the Wild Coast. The southern border between coastal subspecies erythrarchus and subspecies labiatus appears to be at the St. Lucia and Umfolozi systems (Lawes 1990, Dalton et al. 2015). It is estimated that the core area of occupancy for the species is approximately 870 km², as measured by area of intact forest patches.

There has been a reduction and fragmentation of the species range due to past logging practices, slash and burn agriculture and encroaching commercial forestry plantations (Lawes 1992, 2002; Lawes et al. 2000, 2004; Swart and Lawes 1993; Swart et al. 1996). Currently, 30% of suitably-sized forest patches are unoccupied, which may be due to dispersal limitation and/or forest condition (Lawes 2002). In the KwaZulu-Natal midlands, a stronghold of labiatus, forest extent since the 1940s has declined by 5% (Lawes et al. 2004).

Population trend

Trend

The population is suspected to be declining at a rate of ca 1-2% per year (estimated from 1992 to 2002), with a rate of decline of 1% per year suspected to have been ongoing for several decades. This decline is due to habitat degradation and human encroachment.

Threats

This subspecies is threatened by habitat loss and fragmentation. The species is locally threatened by hunting for food, animal parts (used for traditional medicine) and to prevent damage to crops.

Uses and trade

Samangos are protected in South Africa, but still persecuted for fruit-raiding by farmers and gardeners. Pelt and hands, and subcutaneous fat are used in traditional markets and for medicinal purposes, respectively.

Conservation

Listed on Appendix II of CITES and on Class B of the African Convention on the Conservation of Nature and Natural Resources.
