Cactus Plants

Arthrocereusspinosissimus

The relatively small succulent flora of the part of Ecuador considered here includes some 25 species of Cactaceae Madsen 1989 , about 4 poorly understood species of Echeveria currently being studied for the Flora of Ecuador project and the endemic Peperomia graveolens. Of the Cactaceae, 8 species are endemic and of these Armatocereus brevispinus, Cleistocactus leonensis, and Espostoa frutescens are rare and restricted to the Rio Catamayo valley together with some other, non-endemic succulents ,...

Euphorbia Cap-saintmariensis

Succulent Plants

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...

The West Indies

The West Indies Cactus

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...

Priority sites for conservation

Cuban Cactus Scrub

The West Indian endemic succulent flora occurs throughout the many islands of this dispersed archipelago. Nearly every island, or group of islands, has its own local Rather than a few large protected areas, the coverage of such a disperse flora, in terms of conservation needs, requires a number of small-sized sites 1) Coast and lowlands from Guantanamo Bay to Punta Maisi an important part of the south-eastern dry shrubwoods and semi-desert cactus communities with Agave spp., Plumeria spp.,...

Conservation status

The impact of all the various threats on Mexican cacti and other succulents depends on the population characteristics of individual species. The majority of Mexican endangered cacti occur in small, disjunct populations, primarily in arid and semi-arid regions of the country, and a significant proportion of them are represented only by one or a few populations. Most of these species have a combination of biological and ecological attributes making them extremely vulnerable to any form of...

South America

Nigel Taylor, Roberto Kiesling, and Robert Kraus The South American Continent (i.e. Panama southwards, including the Caribbean islands of the Dutch Antilles, Trinidad and Tobago, and those belonging to Venezuela, and the archipelagos of the Galapagos and Fernando de Noronha) has a complete spectrum of environments and an extremely large and varied flora numbering in the region of 90,000 species of higher plants. Of these, succulents probably represent about 1.5 per cent (i.e. < 1400 spp.),...

Threats

Island floras are usually composed of ecologically restricted populations not capable of adapting to major environmental changes. The ability of the island communities to recuperate from external pressures is, in general, reduced. This characteristic makes them particularly vulnerable to degradation. There is a genetic reason for the vulnerability of island communities the reduced gene pool from which the populations that colonised the new biotopes are selected. This gene pool does not have the...

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...

Taxonomic Groups

Photography Madagascar Old

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....

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...

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....

Introduction

Succulent plants have a global distribution and are represented in nearly all habitat types. Over 30 botanical families have succulent plant species, ranging from tiny annual plants to huge trees. The Cactaceae is the largest and perhaps the best known of the succulent plant families. The unifying characteristic of succulent plants is their ability to store water in one or more organs of the plant, giving rise to stem succulents, leaf succulents, and root succulents the so-called caudiciform...

Tropical Africa

The Somalia-Masai region, covering Ethiopia, Somalia, Kenya, and northern Tanzania is the main area of succulent plant diversity in tropical mainland Africa. Between this region of East Africa and the rich southern Africa flora there is a marked decrease in succulent plant diversity determined primarily by climatic factors. In central Africa there is a much more marked summer rainfall allowing the build up of woody biomass and a long enough dry season to allow regular burning of the...

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...

Distribution in southern Africa

Although succulents are found in practically all parts of southern Africa, by far the greatest numbers of species, genera, and families are found in the western arid parts of the region (Hilton-Taylor 1994, 1996a Van Jaarsveld 1978) (see also Chapter 1 for details on their distributions). In terms of phytochoria, biomes, and vegetation types, succulents within South Africa tend to predominate in the Karoo-Namib Region (see White 1983), the Desert, Succulent Karoo, and Nama-Karoo Biomes (sensu...

Whitesloanea Crassa

Although a comprehensive listing of the conservation status of succulent plants of Somalia has not yet been prepared, IUCN categories have been applied to a number of succulent species, especially in the genera Euphorbia and Aloe. WCMC holds records of 61 nationally threatened succulent species for the country. 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...

Based on text compiled by Silvio Fici and Mauricio Sajeva. Table compiled by M. Sajeva and Henk t'Hart. The Mediterranean phytogeographic region is generally considered to include the coastal fringe of the Mediterranean area with the exception of parts of the Libyan, Egyptian, and Tunisian coasts, but with the inclusion of the Atlantic coasts of Portugal, Spain, and Morocco. Macaronesia (Canaries, Madeira, and the Azores) and parts of the Black Sea coasts have a Mediterranean climate and are...
