National Status | Status and Criteria | Endangered A2d | Assessment Date | 2016/11/18 | Assessor(s) | D. Raimondo, S.L. Hutchinson, A.P. Dold, S. Cawe & B.E. van Wyk | Justification | A population reduction of at least 50% over the last three generations (60 years) is estimated due to persistent and consistent destructive harvesting of wild individuals of this species for the medicinal plant trade, and some loss of suitable habitat to timber plantations and crop cultivation. It is a highly sought-after in traditional medicine, and has been over-exploited over much of its range in the Eastern Cape and southern KwaZulu-Natal, especially at lower altitudes, where local extinctions have been observed at several sites. |
Distribution | Endemism | Not endemic to South Africa | Provincial distribution | Eastern Cape, KwaZulu-Natal | Range | Amathole Mountains in the Eastern Cape, extending north-eastwards to southern KwaZulu-Natal and along the eastern border of Lesotho (Hutchinson 2016). |
Habitat and Ecology | Major system | Terrestrial | Major habitats | KwaZulu-Natal Sandstone Sourveld, Midlands Mistbelt Grassland, Mooi River Highland Grassland, Dry Coast Hinterland Grassland, Southern KwaZulu-Natal Moist Grassland, Drakensberg Foothill Moist Grassland, Lesotho Highland Basalt Grassland, uKhahlamba Basalt Grassland, Southern Drakensberg Highland Grassland, Amathole Mistbelt Grassland, Amathole Montane Grassland, KwaZulu-Natal Coastal Belt Grassland | Description | West to south facing slopes along drainage lines, often associated with rocks, and along streams (Hutchinson 2016). |
Threats | | The primary threat to Alepidea amatymbica is over-exploitation for the traditional medicine trade. The species, which is known by the Xhosa as Iqwili, and Ikhathazo by the Zulu, is extremely popular and in high demand.
Dold and Cocks (2002) found Alepidea amatymbica to be one of the 20 most prevalent species in Eastern Cape 'muthi' markets, and estimated that more than 1 200 kg were sold annually in the region. This species is always present at the King William's Town market with material sourced from Pirie, Gwiligwili, Cata, Katberg and other parts of the former Ciskei escarpment, where there is no regulation of natural resource exploitation (A.P. Dold pers. comm. 2016).
The high demand for this species has led to over-exploitation in some areas. The Mthatha muthi market (the largest in the Eastern Cape) had no stock of A. amatymbica during a 12 month survey from October 2015 to October 2016. Traders and harvesters report that it is no longer present in the source areas for the Mthatha market, indicating that it has now very scarce in Transkei area of the Eastern Cape (S. Cawe, Xhosa ethnobotanist, pers. comm. 2016).
Field surveys for a taxonomic revision of Alepidea sections Setiferae and Leiocarpae (Hutchinson 2016) found this species difficult to locate in the wild in all but the most inaccessible areas of the Eastern Cape. At Mount Insizwa in the Mount Ayliff district, local herdsmen informed researchers that harvesters had eradicated all A. amatymbica plants on the lower slopes. Remaining subpopulations could only be reached after more than an hour's walk to more inaccessible areas near the mountain summit. Increasing scarcity of plants in the Eastern Cape have led to harvesters starting to target subpopulations on privately owned farms. Landowners in the Hogsback area are reporting large loads removed by vehicle from their farms (A.P. Dold pers. comm. 2016).
A. amatymbica is not just heavily exploited for Eastern Cape traditional medicine - it has also been recorded in trade as far as the Faraday Market in Johannesburg (Hutchinson 2016) and used by Rastafarian herbal healers in Cape Town (Nzue 2009).
Over-exploitation of wild populations is also occurring in KwaZulu-Natal. A small study conducted in the Coleford area, southern Drakensberg, found that the species had virtually disappeared from communally owned areas, but could still be found in relative abundance on access-controlled privately owned land (O'Connor 2004). The maximum recorded density in privately owned areas was 5.7 plants/sq. m (mean = 1 plant/sq. m), but no plants were seen after nine hours of searching in adjacent communal areas, suggesting it had been extirpated from communal areas. It is important to note that were suitable habitat exists, A. amatymbica can be very common, even locally dominant. However, at a landscape level, it is relatively scarce because the areas of suitable wetland habitat are usually small (O'Connor 2004).
O'Connor (2004) further estimated that the Coleford subpopulation had less than 180 000 individual plants, and that if 1.82 million plants were harvested annually for the Durban market (as cited by Mander 1998), then 10 areas equivalent to Coleford were being cleared annually for one market. While further systematic surveys across these species range are required to establish the extent and rate of decline on communal and private land, the authors of this assessment consider the declines listed above as evidence to suspect an overall population reduction of at least 50% in the past three generations (60 years). |
