Aloe krapohliana Marloth
|Aloe krapohliana Marloth var. dumoulinii Lavranos|
|Krapohl's Aloe (e)|
Status and Criteria
Data Deficient - Insufficient Information
|L. von Staden|
|A fairly widespread species in the arid north-western region of South Africa (EOO 68 000 km²), known from around 20 historical sites. Anecdotal reports indicate significant declines since the 1960s. Renewed interest in mining in Namaqualand poses a significant potential threat. In recent years (2000-2006) at least three subpopulations have been found, but a thorough survey across the extent of its range is lacking. It is probably threatened, but no reliable estimates on population size and rate of decline are available. Indications are that subpopulations are generally very small, but data are insufficient to assign a threat status.|
|South African endemic|
|Namaqualand, from Vanrhynsdorp to the Orange River.|
Habitat and Ecology
|Desert, Succulent Karoo|
|Occurs in the extremely arid northern regions of the Succulent Karoo, on clay, stony (mostly quartzitic) and sandy soils on flats and slopes.|
|A. krapohliana is threatened as a result of overcollection, overgrazing and habitat destruction and mining (Van Wyk and Smith 1996). Severely destructive open cast mining of minerals along the West Coast and on the Knersvlakte as well as diamond mining is affecting a large part of the range of this species. Mining activities have greatly expanded in the last 10 years and existing landcover maps (1996) do not adequately represent the full extent of the transformation. There is also significant potential for expanding mining activities on the Knersvlakte within the next 30 years (Cole 2004).
A. krapohliana is a very attractive dwarf aloe species with exceptionally large and showy racemes (Van Wyk and Smith 1996). It is therefore not surprisingly very popular with collectors and gardening enthusiasts and large numbers of plants have been removed from the wild since the publication of popular books on Aloes such as Reynolds (1969), Jeppe (1969) and Van Wyk and Smith (1996).
Dave Hardy and Hugh Glen on a trip in 1985 could find no plants, this they ascribed to a combination of diamond mining, overgrazing and collectors. Some populations are thus highly endangered if not extinct (Hilton-Taylor, unpublished notes). Three collections since 1985 indicate that there are still extant subpopulations, but urgent surveys are required to determine more accurately how many locations and subpopulations remain.|
Number of subpopulations unknown. Never occurs in large groups. According to Reynolds (1969) A. krapohliana used to be plentiful around Bitterfontein, but it may have subsequently declined substantially, as a survey in 1985 by H.F. Glen and D.S. Hardy failed to locate any subpopulations.
|Protected in the Namaqua National Park and Richtersveld National Park. Trade in A. krapohliana is also controlled through listing on CITES appendix II, this has however been unsuccessful in curbing the wild collection of this species - many illegally collected plants are still available in trade.|
