Of cactus species are CITES-listed — Appendix II by default, with 3 genera elevated to Appendix I; artificially propagated hybrids & cultivated plants exempt

Cactus genera on CITES Appendix I — highest level of protection: Ariocarpus, Discocactus, Obregonia
How CITES Protects Cacti
The Convention on International Trade in Endangered Species (CITES) regulates international trade in cactus species. Every cactus species is covered.
Appendix II — All Cacti
- Covers every cactus species not elevated to Appendix I, except hybrids and artificially propagated specimens
- Export permits required for international trade
- Seed-grown plants from registered nurseries are generally exempt
- Most Trichocereus, Echinocactus, Lophophora species are Appendix II
- Key exception: Artificially propagated hybrids and cultivated specimens are not regulated — this is why seed-grown plants circulate freely in the hobby
Appendix I — Critically Protected Genera
- Ariocarpus (all species) — Living Rock Cactus. International trade almost entirely banned.
- Discocactus (all species) — Night-blooming globular cacti
- Obregonia (all species) — Artichoke Cactus
- These species cannot be traded internationally except for non-commercial purposes (scientific exchange, law enforcement, etc.)
- Appendix I listing has a known side effect: it increases black-market desirability. The rarer a cactus is on paper, the more collectors want it.
🌱 For the grower: If you're trading internationally, ALWAYS keep provenance records (accession codes, nursery receipts, seed source documentation). The Cactus Concession Stand marketplace on Facebook is the most reliable place to find verified, ethically sourced plants with documented provenance.
Peyote (Lophophora williamsii) — A Conservation Case Study
Wild Status
- IUCN Red List: Vulnerable (since 2009) — facing high risk of extinction in the wild
- Texas: Listed as Endangered by the state
- Mexico: Protected under NOM-059-SEMARNAT-2010 — subject to Special Protection
- CITES: Appendix II (export requires permit)
The Klein et al 2015 Study
The most comprehensive analysis of peyote harvesting practices, published in the Journal of Ethnopharmacology. Key findings:
- 1.4-2.3 million peyote buttons harvested annually in South Texas alone (Texas DPS data)
- 10x alkaloid concentration: Mescaline is concentrated ~10x higher in the crown (above-ground photosynthetic tissue) than in the non-chlorophyllous stem below
- Destructive harvesting: Cutting too deep into the non-chlorophyllous stem kills regrowth capacity. Proper crown-only harvesting allows the plant to regenerate — but this technique is not widely practiced
- Wild regrowth: Harvested plants need 10-15+ years to regrow to harvestable size
- Ethnobotanical context: The Native American Church has legal exemptions for religious use, harvesting under permit from TX DPS
Conservation Through Cultivation
The most powerful conservation tool available to the cactus community is simple: grow from seed.
- Seed-grown plants in cultivation DO NOT reduce wild populations — they reduce pressure on them
- Takeaway Tek (sealed container germination) makes seed starting reliable for beginners
- Grafting accelerates slow-growing species to maturity in 2-3 years instead of 10-15
- San Pedro (Trichocereus) is explicitly recommended as a conservation substitute for peyote by Wikipedia and conservation organizations — it grows 10-30x faster
- Every seed-grown cactus is a wild cactus saved. This is the core message of conservation through cultivation.
⚠️ Red flags when sourcing: Wild-collected plants often show signs of field damage (irregular shapes, missing roots, scars). Always buy from reputable nurseries or verified sellers on the Cactus Concession Stand marketplace. Request provenance documentation for rare species. If a deal seems too good to be true, the plant was likely poached.
Threatened Species in This Codex
| Species | CITES | IUCN Status | Wild Threats | Cultivation Status |
|---|---|---|---|---|
| Lophophora williamsii (Peyote) | App. II | Vulnerable | Overharvesting, habitat loss | Widely cultivated from seed |
| Ariocarpus fissuratus (Living Rock) | App. I | Vulnerable | Poaching, habitat destruction | Rare in cultivation, slow |
| Aztekium ritteri | App. II | Vulnerable | Single-valley endemic, poaching | Cultivated, very slow |
| Astrophytum asterias (Star Cactus) | App. II | Critically Endangered | Habitat loss, poaching | Popular in cultivation |
| Echinocactus grusonii (Golden Barrel) | App. II | Critically Endangered (wild) | Dam construction, habitat loss | Ubiquitous in cultivation |
| Echinocactus horizonthalonius (Turk's Head) | App. II | Near Threatened | Slow growth, habitat loss | Uncommon in cultivation |
| Lophophora diffusa | App. II | Vulnerable | Limited range (Querétaro), poaching | Rare in cultivation |
| Obregonia denegrii (Artichoke Cactus) | App. I | Vulnerable | Poaching for collectors | Cultivated, slow |
Ethical Sourcing Guide
Green Flags — What to Look For
- ✅ Provenance documentation — accession codes (EF15A27/EFC1655), nursery receipts, seed source
- ✅ Seed-grown or nursery-propagated — evenly shaped, consistent size, no field damage
- ✅ Known seller reputation — the Cactus Concession Stand marketplace has verified vendor reviews and community vetting
- ✅ Transparent pricing — rare species at fair market value, not suspiciously cheap
- ✅ CITES documentation for international shipments of Appendix II species
Red Flags — What to Avoid
- ❌ No provenance — seller can't tell you where the plant came from
- ❌ Suspiciously cheap — rare species at 10% of market value = likely poached
- ❌ Field damage — irregular shapes, damaged roots, soil that doesn't match cultivation
- ❌ New account / no history — no community reputation or prior sales
- ❌ Cross-border offers for Appendix I species (Ariocarpus, Obregonia, Discocactus) — almost certainly illegal
