Local uses and commercialisation

Succulents are most adversely affected in the USA by collectors and people involved in arid landscaping and horticulture. Despite laws regulating their collection, specimens of Carnegiea gigantea (saguaro) continue to be illegally removed from habitat to be sold in the commercial landscaping trade. Likewise, specimens of Fouquieria splendens (ocotillo) and numerous barrel cacti Carnegiea salvage operation, Arizona. (Ferocactus spp. and Echinocactus spp.) are subjected to collecting from the...

Long term conservation can be served best through education at the grass-roots level. Mexico needs books about cacti and other succulents, suitable for use in basic education. A series of children's books on appreciation of arid habitats and the native flora is now in preparation by Can Te, A.C. Other planned publications include a pictorial encyclopedia of Mexican succulents, introductory and primarily pictorial works on succulent-rich regions, and field identification guides to...

Priority sites for conservation

Madagascar's succulent species occur throughout the island in all major vegetation types. There are certain areas which are outstanding in terms of their succulent richness and diversity 1) The whole area of southern xerophytic thicket community, dominated by Didiereaceae and shrubby or arborescent Euphorbia spp., and resticted to a small coastal region about 50 km wide, is an international conservation priority. According to Rauh (1978d), All in all, the vegetation of the precipitation-poor...

Southern Africa

Southern Africa (including Botswana, Lesotho, Namibia, South Africa, Swaziland, and Zimbabwe) has long been as an area of remarkable plant diversity with extremely high levels of endemism (see Cowling et al. 1989 Cowling and Hilton-Taylor 1994 Gibbs Russell 1985 Goldblatt 1978 Good 1974). The high levels of diversity and endemism found in the flora in general, also extend to the succulent plant groups as has been shown by Barkhuizen (1978), Court (1981), Van Jaarsveld (1987) and Smith et al....

Threats

Very few of the succulents in Botswana occur in conservation areas, and therefore they are all potentially under threat. Fortunately, due to the low population density and relatively undisturbed nature of much of the vegetation, few species are considered to be threatened, although an assessment of the situation is long overdue. Many succulents in Botswana are utilised for a variety of ethnobotanical purposes, e.g. Euphorbia duseimata is used to induce vomiting after poisoning and in the...

Action Proposals

The actions required to conserve the world's diversity of succulent plants are many and varied. The review undertaken by the IUCN SSC Cactus and Succulent Specialist Group in order to prepare this document indicates some of the main activities which should be undertaken immediately. These can be divided into various broad categories. Some are straightforward and relatively inexpensive for example, provision of information to conservation decision makers. Others are more complex, involving, for...

Cites

Mexico is a recent signatory of CITES, and SEMARNAP, as the Managment Authority, has the responsibility of enforcing regulations pertaining to the international trade in succulents. At present there appear to be misunderstandings by many people about the purpose of CITES. Many Mexicans and foreigners do not understand the permit system presently in operation by SEMARNAP, and nearly all foreign collectors have ignored the system. In addition, inspectors at the international borders need training...

The West Indies

The Caribbean islands form an archipelago of over 1000 islands of considerable range in size, altitude, soil types and environmental niches. Exposed land surfaces cover a distance of 2700 km from Barbados on the east, to the western tip of Cuba, while the distance from Grenada in the Lesser Antilles to the northern tip of the Bahamas is 1900 km. The islands range in size from Cuba, with 114,500 km2 and a vascular flora of over 6000 species, to islets of small rocks of a few square metres and a...

Box 33 Didiereaceae a succulent family endemic to Madagascar

The Didiereaceae Drake is a small family endemic to Madagascar consisting of four genera, Alluaudia, Alluaudiopsis.Decaryia, and Didierea, with eleven species. The spiny cylindrical or conical pachycaul stems of the plants give a superficial resemblance to columnar species of Euphorbia or cacti and the Didiereaceae are sometimes known as the cacti of the old world. The stems are woody, and scarcely succulent, with limited space for water storage. The plants have simple, deciduous leaves, except...

The Agave family (Agavaceae Endlicher) is a group of economically important succulent plants with a natural distribution in the drier regions of the tropics and subtropics. The botanical limits of the family are undecided, but for the purposes of this Action Plan the Agavaceae is considered to comprise 18 genera and approximately 625 species. Many of these species remain poorly known in the wild. Herbaria and field surveys are urgently needed to determine conservation status for the species....

Delays and expense in obtaining permits has hindered legitimate export of artificially propagated plants. Inadequate enforcement of national legislation results in some illegal trade in rare plants. However, the standard of reporting for plants is generally poor. Many countries, for example, report only to family or generic level for cacti and other succulent plants, and other countries do not report on the plant trade at all. Nevertheless, a significant body of data on the international...

Data sheets on Euphorbia cameronii and Whitesloanea crassa are included in the IUCN Plant Red Data Book Lucas and Synge 1978 . The genus Pseudolithos is endemic to Somalia. All four...
