Illegal Succulent Trade Threatens South Africa’s Unique Plant Biodiversity

CAPE TOWN, SOUTH AFRICA — A growing illegal trade in rare succulents is threatening South Africa's unique plant biodiversity, as increasing demand from collectors fuels widespread poaching across some of the country's most ecologically important regions.

South Africa is among the world's most biodiverse countries for succulent plants, with many species concentrated in the Northern and Western Cape, particularly within the Succulent Karoo Biome.

The plants, which have fleshy leaves or other water-storing parts that allow them to survive in arid environments, have become highly sought after by collectors, creating a lucrative market for illegal harvesting.

According to South Africa's Parliamentary Standing Committee on Local Government, Environmental Affairs and Development Planning, the illegal collection of protected succulent species has increased significantly in recent years.

Western Cape Provincial Parliament member David Bryant estimates that around 2.5 million succulents have been poached across the Western and Northern Cape since 2018, with no clear indication that the trade is declining.

He said succulent poaching can be particularly attractive to criminal networks because it generally carries fewer immediate physical risks for perpetrators than wildlife poaching involving animals such as rhinos.

Threat to Rare Plant Species

The scale of the trade is raising concerns about the long-term survival of species found nowhere else on Earth.

The Cape Floristic Kingdom, a UNESCO World Heritage site, contains more than 9,000 plant species, around 70 percent of which are endemic to the region.

Many of these plants are succulents, making them vulnerable to collectors and organised poaching networks.

The remote locations where many species grow further complicate enforcement efforts, allowing illegal collectors to operate in areas that are difficult for authorities to monitor.

Bryant warned that the trade could result in the permanent loss of important biodiversity.

He said the illegal succulent trade involves a diverse criminal value chain, including networks that are also involved in other illicit activities.

Rare Species Face Extinction

South Africa has more than 4,700 succulent species, with some already facing severe population declines.

Nine species of Conophytum have become extinct in the wild, while a significant proportion of the genus is now classified as critically endangered.

Emily Norma Kudze, senior scientific coordinator for the illegal succulent trade at the South African National Biodiversity Institute (SANBI), said some species are found only in highly restricted locations.

She said authorities have encountered cases where thousands of plants belonging to a single species were removed from the wild.

When large numbers of plants are removed from an isolated population, the remaining plants may no longer be sufficient to reproduce and sustain the species.

This can result in populations being considered functionally extinct, even when a small number of plants remain.

Poverty and International Demand Fuel Trade

The illegal trade is being driven by both international demand and local socio-economic pressures.

Collectors overseas are willing to pay high prices for particularly rare species, while poverty in isolated communities, especially in the Northern Cape, can encourage residents to participate in harvesting operations.

Organised criminal syndicates are reported to recruit local collectors to remove plants from the wild before moving them through major South African cities, including Cape Town and Johannesburg, and eventually into international markets.

Authorities have seized more than 2.5 million illegally harvested plants since 2018, although officials believe significant numbers continue to evade detection.

Authorities Step Up Response

South African authorities have introduced a National Response Strategy involving multiple government agencies to tackle succulent poaching.

The strategy has included improved coordination, surveillance operations and specialised enforcement training, resulting in arrests of some alleged syndicate leaders.

SANBI has also established a Succulent Poaching Working Group to coordinate conservation efforts and strengthen the response to the crisis.

Kudze said conservation initiatives include educational programmes in schools, restoration projects and training for prosecutors to help them understand the environmental consequences of plant poaching.

Authorities have also secured lengthy prison sentences in some cases, including sentences of up to 15 years for individuals convicted of illegally removing protected plants from the wild.

Conservation Efforts Gain Momentum

Kudze said the response is beginning to generate momentum, with greater awareness of the seriousness of succulent poaching among communities and law-enforcement agencies.

Conservation officials are also working to reduce demand and educate communities about the ecological importance of the Succulent Karoo.

Despite these efforts, officials warn that continued international demand for rare plants remains a major challenge.

South Africa's parliamentary environmental portfolio committee has expressed concern over the scale of the threat and is calling for urgent, coordinated action to protect the country's plant biodiversity.

For conservationists, the stakes extend beyond individual plants. The loss of rare succulent populations could permanently erase genetic and ecological resources that cannot easily be restored once they disappear from the wild.
