According to the first complete, global evaluation of the species group by NatureServe, IUCN, and collaborators, published in the journal Nature Plants, 31% of cactus species are in danger of going extinct. Cacti are now more endangered than animals and birds, making them one of the most threatened taxonomic groups included on The IUCN Red List of Threatened SpeciesTM.
In light of the fact that more than half of the 1,480 cactus species in the world are used by people, the paper claims that cacti are coming under growing pressure from human activities. The primary risks to cacti, impacting 47% of vulnerable species, are their unsustainable harvesting and the illegal trade in live plants and seeds for the horticulture sector and private collections.
IUCN Director General Inger Andersen commented, “These findings are troubling. They affirm that wildlife trafficking affects many more species than the charismatic rhinos and elephants that typically garner global attention. The scale of the illegal wildlife trade, which includes trade in plants, is significantly bigger than we had previously imagined. If we wish to stop the continuing decrease of these species, we must immediately increase international efforts to combat the illegal wildlife trade and boost the execution of the CITES Convention on International Trade in Endangered Species.
Small-scale annual agriculture, which affects 24 percent of threatened species, and small-scale animal ranching, which affects 31 percent of threatened species, are further dangers to cactus. Other significant concerns to these species include residential and commercial development, quarrying, aquaculture—particularly shrimp farming—which invades cacti habitats.
Arid habitats in the New World are fundamentally dependent on cacti for the survival of numerous animal species. They serve as a food and water supply for a variety of animals, such as deer, woodrats, rabbits, coyotes, turkeys, quails, lizards, and tortoises, all of whom contribute to the distribution of cactus seeds in exchange. Hummingbirds, bats, bees, moths, and other insects all receive nectar from cactus flowers, which helps to fertilize the plants.
People frequently employ cactus species in the horticulture industry, as well as for food and medicine. For rural people, their fruit and extremely nourishing stems are a crucial source of sustenance. One Opuntia ficus-indicaa “prickly pear” cactus stem, popularly known as “nopal” in Mexico, has the same nutritional value as a beef steak, and the roots of species like Ariocarpus kotschoubeyanus, which is designated as Near Threatened, are used as anti-inflammatories.
86 percent of vulnerable cacti used in horticulture are acquired from wild populations; trade in cactus species occurs on a national and international scale and is frequently illegal. The bulk of the illegal cactus trade comes from collectors in Europe and Asia. Because they are so rare, wild-collected specimens are in high demand.
According to Barbara Goettsch, principal author of the study and co-chair of the IUCN’s Cactus and Succulent Plant Specialist Group, “The results of this evaluation come as a shock to us. “We did not anticipate that cactus would face such serious threats and that illegal trading would play such a significant role in their deterioration. For local people who depend on wild-harvested fruit and stems, as well as for the diversity and ecology of dry terrain, their removal could have far-reaching effects.
This study emphasizes the need for more effective and long-term management of cactus populations in a variety of countries. These plants can no longer withstand such high levels of collecting and habitat destruction due to the current expansion in the human population.
Due to the majority of cactus species’ inclusion on the CITES appendices since 1975 and the greater accessibility of plants cultivated from seed on the global market, the illegal trade in cacti has been somewhat curbed. However, the threat of collection still exists, particularly in nations where CITES has just recently been put into effect.
For instance, the once-abundant Echinopsis pampana, a native to Peru’s puna desert, has had its population decline by at least 50% over the past 15 years due to illicit collection for the decorative plant trade. The places where the species historically lived have now experienced land use changes for housing, making its demise irreversible. The species is currently considered endangered.
The many different forms and exquisite flowers of cacti are well known. Except for one species, Rhipsalis baccifera, which is also found in southern Africa, Madagascar, and Sri Lanka, they are endemic to arid regions of the New World. Threatened cactus species are particularly prevalent in the dry regions of Brazil, Chile, Mexico, and Uruguay. Even though they are rich in biodiversity, these places are seen as uninteresting and inconsequential, hence arid-land species like cactus are frequently disregarded in conservation planning. In order to better conserve the species, the authors of the research emphasize the need to increase the coverage of dry land protected areas and to spread awareness of the need of sustainable gathering of cacti from the wild.
According to Kevin Gaston from the University of Exeter, who co-led the Global Cactus Assessment, “the stunning results highlight the critical need of funding and conducting evaluations of the vulnerable status of all species in large groups of plants, such as the cacti. Only by doing this will we be able to acquire a comprehensive understanding of what is happening to them at a time when, as shown by the cactus, they may be facing tremendous human pressure.
According to Mary Klein, President of NatureServe, “cacti are exceptional plants that concentrate water and nutrients required by natural and human societies, in some of the world’s most difficult conditions.
This study indicates that cactus are particularly susceptible, but it also shows that we can preserve these natural wonders for the future by paying close attention to removing dangers like illicit extraction.
Succulents are they in danger?
The diversity and abundance of many succulents are being impacted by the high requirements of these plants. Additionally, the anthropogenic activities in their farming regions are reducing the amount of growth land. Some succulents are being driven to extinction as a result of this unbalanced condition, while others are being added to the IUCN’s red list of endangered species.
Mammillaria herrerae, Agave pax, Aloe pillansii, Estevesia alex-bragae, Parodia rechensis, Monanthes wildpretii, Discocactus subterraneo-proliferans, and Rhipsalis triangularis are a few examples of endangered succulents.
Despite the fact that there are just a few of these species listed, the IUCN reports that “their study shows cactus to be one of the most vulnerable taxonomic groupings studied to date: almost a third (31 percent) of the 1,478 species evaluated are categorized as threatened.
Why do cactus matter?
Cacti have crucial ecological functions to fulfill. For desert-dwelling species like deer, quail, wild turkey, pack rats, gophers, rabbits, and tortoises, they serve as a source of food and water (Patriquin 2007, Taylor 1998). Many animals eat its fruit, and woodpeckers build their nests in their stems. The nectar from the saguaro’s blossoms is consumed by hummingbirds, bats, bees, moths, and other insects. Without cacti blooms as a source of food, hummingbirds would find it challenging to migrate over the southwest desert between their winter and summer ranges.
Only moths can reach the nectar from some cactus blooms, which grow in long tubes up to 30 centimeters (12 inches) in length, pollinating the flowers as a result. Additionally, there are specializations for specific bee species, hummingbird species, and bat species.
The seeds are largely dispersed by goats, birds, ants, mice, and bats.
Cacti may be consumed?
You can either leave the pads whole, cut them into strips, or chop them into cubes, depending on how you intend to use this vegetable. Cacti that are edible can be eaten raw or cooked. They can be grilled, sautéed, boiled, simmered, or deep-fried. Their ideal serving texture is soft and crispy. The texture of overcooked pads will be slimy. Combine them with various ingredients to create a range of wholesome, nutrient-rich recipes. Here are some recommendations:
You might need to switch the water you’re using to boil the pads and re-boil them. It’s possible that the sap coming from the pad is thick. As a general rule, the sap will be thicker the thicker the pad. After draining, the pads are washed in cold water. Why not prepare a traditional Mexican salad with diced tomatoes, cilantro, jalapenos, onions, and lime juice? Salt and pepper are other good additions.
Grilling
Season the pads well with salt and pepper if grilling them. When the pads are somewhat brown in color and soft to the touch, they are prepared. Additionally, you may season them with a dash of salt, a squeeze of lime juice, and a little olive oil.
Cactus pads can be added to various meals, either raw or cooked, to create flavorful, nutritious foods. They can be blended into a smoothie, or they can be diced and added as a topping to yogurt or cereal. Why not attempt incorporating them into stews, casseroles, and eggs. They make a delicious addition to quesadillas and salsa. You can choose to consume this adaptable, healthy vegetable alone, in a robust vegetable soup, in a fruit or vegetable salad, or even simply by itself! It can also be prepared into a jelly. Cactus pads can also be pickled and used to other meals as a condiment.
Cacti are they healthy for the environment?
This is especially true if you have one of these succulents at your office. Cacti plants will always remind you of the need to conserve the environment and plants in addition to increasing your productivity.
You’ll feel good and remember how important plants are to the natural ecology if you take care of a tiny, vibrant cactus plant every day. It might increase your awareness of other environmentally friendly practices like recycling, using less paper, and energy conservation.
In the long run, if everyone adopts a philosophy of protecting our environment, it can have a profound impact.
There is an increasing need for more people to take on the responsibility of caring for plants due to the rise in harmful emissions into the environment and the impending threat of global warming. By taking care of that cactus, you may do your small part.
What succulents are prohibited?
Dudleya protection legislation was recently passed in California. It joins two other statutes that make felony charges out of stealing saguaro cactus and Venus flytraps in the US. Do you believe that legislation of this nature can genuinely change things?
Jared Margulies
On this issue, I have conflicting opinions. Practically speaking, having a rule that is particular to a species or genus makes it much easier for law enforcement to prosecute this kind of behavior.
We also know that in nations where extremely harsh penalties have been imposed for crimes like poaching rhino or elephant horn, for example, it is frequently those with the least agency and capacity who are frequently placed in extremely trying circumstances who are punished rather than those who stand to gain the most economically.
If there was no customer demand, these trades would not exist. That suggests to me that consumer education is crucial. I believe that the great majority of people purchasing these plants genuinely had no idea what was happening.

Are your typical houseplant customers driving the illegal trade in succulents? Or are they all collectors?
What separates a houseplant lover from a collector isn’t something that can be said with absolute certainty. Are you a collector if you discover 300 houseplants when you awaken one day? But it is quite vague.
It is quite unlikely that you will purchase an illegally obtained or wild-harvested houseplant if you get them from a reputable [source], particularly a neighborhood shop or independent houseplant vendor. I do advise people to question the folks they purchase their plants from; they ought to be able to respond. There are some cacti species that, for example, can live to be as ancient as humans and take decades to reach a width of a few millimeters. Some people want to jump the gun and demand bigger plants, which occasionally encourages people to obtain plants that have been collected from the wild.
Be cautious while purchasing plants online, especially from foreign purchasers, though not only because there are undoubtedly people attempting to sell items illegally within the US. Does the plant appear to be damaged? Has it been bitten by insects? Has it been bleached? A plant’s signs of life are all red flags that it might not have originated from a greenhouse, which is where you should be purchasing houseplants. We must increase the level of consumer education. However, I also believe that we shouldn’t scare people into believing that all of the plants they have in their homes are suddenly illegal—they most likely aren’t.
So, if you’re looking for a succulent you saw on TikTok, you’re probably not contributing to the illegal plant trade on a global scale.
Most likely not. There are some exclusions. The mesembs family of plants, which includes lithops and conophytum plants (cute little succulents that take forever to grow), has witnessed a major increase in attention since the start of the epidemic.
Currently, illicit harvesting is a major issue in South Africa, and a significant portion of that is being caused by the plants’ recent spike in popularity. As with the dudleya trade, I don’t believe this is because the plants are wild; rather, I believe it is because they suddenly become highly popular and are simple to pull out of the ground and transport around the world.
As you previously mentioned, plant poaching receives much less attention than animal poaching. What is at risk when we discuss the extinction of biodiversity in succulents?
Cacti and other succulent plants are essential components of ecosystems, leaving aside the very serious moral and ethical problems associated with the illicit wildlife trade. Some dudleya species are confined to one side of a little island off the coast of California, Mexico, or Baja. They don’t have substitutes. The habitat ranges of many other cactus and succulent species are also severely constrained, and many of them barely overlap at all. Therefore, the effects of even a small number of individual actors can be very significant. If someone really wanted to, they could poach some dudleya species to extinction in a single day. These plants are unable to flee.
According to the International Union for the Conservation of Nature, ornamental gathering is one of the main dangers to the survival of nearly a third of all cactus species. Some members of the mesembs family may have been unlawfully harvested to extinction in the wild in South Africa during the past year. There is still hope since there are excellent people working on the ground who have rescued many of those species in an effort to return them to their natural home. The question is: What do we want from these plants, exactly? Can we change such [desires] so that they really facilitate more positive interactions with the nonhuman world?
If you don’t spend time in locations affected by environmental issues, it may be challenging to relate to them personally. What effect, for instance, is this loss of biodiversity having on city residents?
When ecosystems begin to deteriorate, cities won’t endure very long if we take a really significant step back. There wouldn’t be much hope left for humans if plants stopped to exist and ecosystems started to break down fundamentally.
Many people might assume that I’m against the idea of amassing large collections of succulents or houseplants in my home. I firmly reject that position. We have a lot to learn from coexisting with these species. Some are more suited than others to coexisting with us indoors.
But in order to develop ways of relating to those geographies and the people who live with them, it’s crucial that people learn about the origins and natural histories of the plants that people maintain in their homes.
The Christmas cactus is a great illustration; it grows in the crevices of trees, much like orchids, in the lush, moist tropical woods of [South America]. This plant has arguably been one of the most productive in the entire planet. Millions of pets are purchased and traded each year all over the world, and half of them end up dead because their owners leave them on a radiator or some other surface. Without significant intervention, some species in that family are likely to go extinct in the coming decades due to habitat loss and fragmentation, as well as excessive collection for the ornamental trade.
This plant is simultaneously found everywhere and yet it might not be found where it originated over millions of years, which creates an intriguing tension. To encourage individuals who love and look after houseplants to consider how that can relate to carrying out conservation activities, it is vital to raise awareness of those links.
At the moment, sustainability is a hot topic. As a society, we are carefully considering the environmental impact of the food, clothes, energy, and transportation choices we make. Should we approach our indoor plants in a same way?
Our world is highly commercialized. Plants and indoor plants are not an exception to this. The ability to extend the life of many of these plants is one of their many appealing qualities. Cacti can be sliced in specific ways that cause them to grow “pups,” or tiny infant clones of other cacti.
We can cultivate kind and considerate relationships with other people by cultivating compassionate relationships with plants. Before you go out and buy a new plant, consider that. I’m glad to see these websites and Instagram groups where individuals trade plants for those who can’t afford them or simply want them. That’s a really good approach to settle in a neighborhood with people who care about plants and gain a lot of knowledge in the process.
One thing that frequently saddens me is seeing people acquire succulents or cacti and then treat them like architectural accents in their homes rather than as living beings. simply letting them wither before replacing them with another $5 plant six months later. That is a failing to appreciate that plants may teach us a lot and that they do need care.
