Succulent Poaching and Climate Change: A Dual Threat to Endangered Plants
Illegal plant collecting and climate shifts are devastating South Africa's rare succulents and the fragile ecosystems they support.
In the arid landscapes of South Africa, an ecological crisis is unfolding. Once rugged survivors of harsh climatic extremes, the region’s unique succulents now face a twofold threat: relentless illegal harvesting and the accelerating impact of climate change. As demand for rare, collectible plants surges globally, entire species edge toward extinction, imperiling not only botanical diversity but also the stability of an ancient ecosystem.

The Succulent Karoo: A Hotspot of Diversity
The Succulent Karoo biome, spanning parts of South Africa and Namibia, hosts the world’s greatest diversity of succulents. Characterized by its aridity, remarkable plant adaptations, and fragile soils, the Karoo is home to over 6,000 plant species — more than a third of which are found nowhere else on Earth.
- Endemism: Over 2,000 plant species are endemic to this region.
- Key groups: Iconic species include Conophytum (button plants), Lithops (living stones), and several aloe species such as the quiver tree (Aloidendron dichotomum).
- Sensitivity: Succulents here are exceptionally slow-growing, long-lived, and sensitive to habitat disturbance.
The Rise of Succulent Poaching
While some plants have always found their way into collectors’ hands, the recent surge in poaching is unprecedented. Organized criminal groups exploit both the region’s biodiversity and global fascination with exotic plants, especially after trends exploded on social media platforms during the Covid-19 pandemic. Native succulents — often hundreds of years old — are stripped from their habitats to satisfy an overwhelming ornamental market demand.
- South African National Biodiversity Institute (SANBI) estimates over 1.5 million wild plants have been illegally harvested in just three years.
- Since 2019, the IUCN Red List has added over 210 succulent species, primarily due to poaching and climate pressures.
- Collectors pay top prices for mature specimens that cannot be artificially or rapidly replaced.
Main Drivers Behind the Surge
- Global fascination: Urban houseplant trends, amplified by influencers, have led to a craze for rare succulents.
- Online marketplaces: A vast illegal trade has flourished, with plants shipped to Asia, Europe, and North America.
- Paucity of large specimens: Slow growth in cultivation means wild harvesting is often the only way to obtain sizable plants.

Climate Change Intensifies the Crisis
As if poaching were not devastating enough, climate change compounds the threat. The Karoo has endured its worst drought in recorded history over the last decade, while models predict ongoing aridification, fewer rainfall events, and rising maximum temperatures.
- Increased droughts: Many succulents are uniquely adapted to periodic water scarcity, but the new extremes outpace their ability to survive or reproduce.
- Higher mortality: Populations already diminished by poaching face higher death rates due to environmental stress.
- Projected population declines: Studies predict up to 90% decline for some species, like the Giant Tree Aloe (Aloidendron pilansii), by 2080 if trends persist.
Wider Ecological Impacts
The loss of succulent diversity does not only impoverish botanical variety; it triggers harmful cascading effects across the fragile Karoo ecosystem:
- Erosion control: Dense succulent mats stabilize soil and limit desertification.
- Wildlife shelter: Many animals rely on succulents for shade, moisture, and hiding places.
- Disrupted food webs: Seed dispersers, pollinators, and microfauna are jeopardized by plant extinctions.
Katherine Forsythe (WWF South Africa) stresses, “Once an area is disturbed, the plants are unlikely to come back anytime soon … and only if there are seeds left.”
Species on the Brink
The greatest poaching pressure concentrates on Conophytum — a genus of ‘button plants’ comprising nearly 190 species. Once abundant, these tiny, cryptic succulents are now becoming virtually invisible in the wild.
| Genus/Species | Status | Main Threats |
|---|---|---|
| Conophytum spp. | 97% Threatened; 45% Critically Endangered | Poaching, habitat loss, climate change |
| Quiver tree (Aloidendron dichotomum) | Vulnerable | Climate change, drought, harvesting |
| Giant Tree Aloe (Aloidendron pilansii) | Critically Endangered | Climate change; projected 90% decline by 2080 |
| Lithops spp. | Several at risk of extinction | Poaching, habitat loss, climate variation |
In some tragic cases, the number of confiscated poached plants exceeds known wild population counts, suggesting several species may already be extinct in the wild.
The Illegal Succulent Trade
A lucrative global market drives the illegal trade:
- Organized networks: Plant trafficking syndicates remove mature plants and ship them worldwide using falsified paperwork.
- High mortality: Over 1.16 million plants (650+ species) were seized by May 2024; the majority have since died in captivity, further complicating reintroduction efforts.
- Disease and adaptation issues: Poached plants often cannot be returned to the wild due to disease risk and their acclimatization to “soft” greenhouse conditions.
Efforts to repatriate confiscated succulents have been largely unsuccessful. Even when plants survive relocation, the threat of recurrent poaching persists, making it difficult to restore wild populations.
Conservation and Response Strategies
Recognizing the crisis, key stakeholders have united in a collaborative conservation initiative:
- National Response Strategy and Action Plan: In 2021, SANBI, WWF, NGOs, and government agencies launched a comprehensive program to counter illegal harvesting and promote sustainable, socio-economic alternatives.
- Main objectives:
- Establish international and national protected succulent collections outside natural habitats.
- Enhance regulations for compliance and sustainable use.
- Facilitate local community involvement in monitoring and conservation.
- Explore legal market opportunities to support socio-economic development and reduce poaching incentives.
The major hurdle remains securing sustained funding to scale and maintain these interventions.
The Role of Local Communities
Community participation is critical for the success of conservation:
- Guardianship and monitoring: Locals are often best placed to detect poaching and report suspicious activity.
- Alternative livelihoods: Sustainable cultivation and legal trade, if established and regulated, could offer economic opportunities that replace poaching income.
- Education and pride: Programs that foster local appreciation of endemic flora strengthen resistance to illegal trade.
Challenges in Rehabilitation and Reintroduction
Recovering decimated wild populations faces numerous scientific and logistical obstacles:
- Lack of provenance: Often, origin sites of confiscated plants are unknown, making replanting risky or impossible.
- Adaptation and disease: Greenhouse-acclimated plants may not survive harsh desert reintroduction or could carry pathogens threatening native populations.
- Ongoing vulnerability: Even successfully reintroduced populations remain at risk from repeat poaching and climate shift.
Attempts to return poached populations to their native habitats have seen partial success, but both relocation sites have suffered renewed illegal harvesting.
Ways Forward: Cultivation, Policy, and Public Awareness
Solutions to the succulent crisis must be multi-faceted and international in scope:
- Stricter enforcement and global cooperation: Stopping transboundary poaching requires robust law enforcement, cross-border cooperation, and stricter regulation of the commercial plant trade.
- Botanical garden conservation: Safe ex-situ collections help preserve species for eventual restoration.
- Promoting legal, sustainable cultivation: Encouraging home and commercial production of popular succulents reduces pressure on wild stocks.
- Education campaigns: Informing the public, especially buyers, about the risks and ethics of wild-collected plants is essential to shrinking illicit demand.
Ultimately, as the climate warms and wild populations dwindle, the future of South Africa’s iconic succulents — and the vibrant ecosystems depending on them — relies on swift, innovative, and well-funded action.
Frequently Asked Questions (FAQs)
Q: Why are succulents particularly vulnerable to poaching?
A: Many succulent species are extremely slow-growing and occur only in limited, specialized habitats. Removing mature plants irrevocably alters populations, as it can take years or decades for replacements to grow. Their cryptic appearance and unique appeal further drive illegal collection.
Q: What are the ecological consequences of succulent loss?
A: Succulents stabilize soils, combat erosion, and support arthropods, reptiles, and mammals. Their loss accelerates desertification, diminishes biodiversity, and destabilizes food webs in the fragile Karoo biome.
Q: Can confiscated succulents be returned to the wild?
A: Most cannot. Without knowledge of their original locations and because of their acclimation to greenhouse environments, reintroduction is rarely successful. Disease transmission and poaching risk remain concerns.
Q: What can plant enthusiasts do to help?
A: Buy only certified, legally propagated plants. Avoid supporting sellers who cannot prove legal sourcing. Support conservation initiatives and consider growing species from seed rather than purchasing wild-collected specimens.
Q: Is it possible to reverse succulent population declines?
A: With coordinated conservation, sustainable cultivation, and demand reduction, population stability is achievable. However, for certain species already poached to extinction in the wild, there is no second chance unless seeds or living collections survive.
