A conversation with the author of The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade

It was questionable if we needed a second season of Tiger King — or, let’s be honest, a first season. Regardless, if Netflix ever decides it’s interested in a story that features surprisingly charming criminals, IWT violations, and yes, even possibly murder (but without the tabloid tone and mullets), producers might look in the future to Jared D. Margulies’ delightful debut, The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade.
Wait, illicit succulent trade? you might be wondering. Oh yes.
From the cliffs of California and the deserts of Brazil to the markets of Seoul and the private greenhouses of Czechia, Margulies follows the extraction and relocation of plants so rare that they might only exist in one valley or mountainside in the world. Weaving in ample philosophy and research about what drives these sorts of obsessions — as well as his personal reflections as he, in turn, is captivated by the lovable, spiky plants — The Cactus Hunters is just the right balance of edgy and academic.
Last week, I caught up with Margulies about the process of researching the book, being mistaken for an undercover cop by his subjects, and the lie that is “the green thumb,” among other topics. Our conversation has been edited and condensed for clarity.
You open The Cactus Hunters with a story about how you were going to study the illegal trade of tiger bones when you came across a story about saguaro cactus rustling that piqued your interest and sent you on this journey. What most stands out to you as the differences between the illegal trade of animals and animal products and the world of illegal cactus trading?
To clarify, I never actually got around to studying the illegal trade in tiger bones. I had encountered it a little bit in my past research on human-wildlife conflicts.
But there are a lot of important differences: One of the things that made the illegal plant trade so interesting to study, compared to illegal trade in animals, is that it receives a lot less attention, so there was just a lot more to learn that people hadn’t already researched. But also, the way that this material and these plants can move around the world — there are so many more options available because of the nature of plants. So if what you’re after is the genetics of the plant, to be able to grow them somewhere else in the world, there’s not just the one plant but there’s the cacti propagate, for instance. Pups. Their seeds. You can make cuttings of plants. None of these things are really available to people interested in illegal trade and animals. That affects supply chains and how these things can move around the world.
Also, because of the lack of attention to illegal plant trade compared to animal trade, the subject is a lot less criminalized. I would argue that my access to informants and research participants was a lot better because it did happen that, every now and then, people thought I was a cop. Or maybe, like, an undercover detective. But usually within pretty short order, they realized that wasn’t the case and I was generally interested in trying to understand their perspectives. I think that it would be a lot harder to develop trust within certain trades that are a lot more heavily criminalized.
Over the course of the book, you encounter the Indiana Jones of plants and the Robin Hood of cacti, among others. Can you talk a little about why these enthusiasts, who clearly care deeply about conservation, sometimes break the law by smuggling seeds or entire cacti out of the places where they naturally grow?
One of the fascinating things that really gripped me was this seeming contradiction, where you have people who are made out as conservation villains by certain actors seeing themselves as unsung conservation heroes. The reason for that is, for a lot of these collectors, they saw their community as really passionate people who wanted to get access to the plants that become objects of their desires. By and large, the people who want these plants aren’t trying to do harm to the species in the world, and they care a lot about them. But they also recognize that in their desire is something fairly insatiable and that people are going to go to lengths to get the plant that they have to go to.
For a lot of these collectors, they might see engaging in a kind of illegal activity as still a socially acceptable behavior, if it meant it got material out into the world in a way that people might want it. And the goal there, the long-term goal, is to try to reduce demand on wild harvesting of plants and wild populations. If you get a little bit of material out into the communities that delight in these plants, then you can start grafting them, propagating them, growing them from seed, and, in theory, get that material out into the world.
I wanted to take that perspective seriously. It’s a hard thing to study empirically and so it was important for me to try to be open to a really diverse set of opinions about the right way to do conservation.
You leave most of the sources in the book, including those working within the law, anonymous. Why did you make that decision?
The really short answer is, I was part of a larger research project called BIOSEC, which was run by Professor Rosaleen Duffy at the University of Sheffield in the Department of Politics and International Relations, and we were using a fairly symmetrical ethics approval process, or what in the U.S. we would call an institutional review board approval. Because a number of us were studying illicit economies, in order to ensure research-subject protection and anonymity and security, we were required to make all of our sources anonymous.
But this caused some issues because, on the one hand, it meant that everyone in the book is anonymous, even if they’re people who are law enforcement officials or botanists who would have probably really enjoyed having their names in the book. I regret that.
Most interesting, though, were the number of collectors who were mad at me because they’re also anonymous. One of the reasons for that was they saw anonymity as being suggestive of wrongdoing and for a lot of these people, they don’t feel like what they’re doing is wrong, necessarily, even if it’s against the law. They wanted their story told. I think one of the reasons I had good access to the kinds of interlocutors I had was because they felt like I was providing a space for them to get their version of the story out into the world.
You were asked to be an expert witness in a case against a South Korean smuggler who took thousands of plants from the California coast. How do you navigate moments like this, when your position as an illicit trade researcher is perhaps in tension with your own ethical code?
This was a really difficult decision for me, and I write about this. I went back and forth about whether or not to serve as an expert witness, which in this case just required writing a statement. I never had to go to court or, you know, be on a witness stand — thank goodness. But I go back and forth about if I would do it again.
I think that in the end, I chose to do it because I realized that my testimony would only serve to probably reduce the sentence that this person was facing. And I don’t say that because I think that what they were doing was okay. It was really bad and really harmful to this species of plant. I just don’t think that criminalization and incarceration actually do rehabilitative work or serve much function. It costs us a lot of money as taxpayers and causes harm.
It was complicated; I guess that’s how I would leave it. I debated whether or not to include [the story] in the book but I felt like, in the end, it would be wrong not to include it. I think that if people eventually found out I had served in that capacity, they might felt like I was trying to not disclose something. But yeah, I have some ambiguous feelings about it. In the end, what I was asked to actually do was very limited: I was just asked to put a value on these plants. But as I wrote in my letter to the judge, that value in monetary terms is such an arbitrary thing. The price of those plants has declined precipitously since I wrote that, and it had already gone down a lot since the person who sold them stole them. How interesting, though, that the court of law — at least in the United States — in order to assess the damage done to the state, it had to be valued in monetary terms.
I really liked the inclusion of the story. It’s interesting for a researcher of illicit and illegal trade to all of a sudden be dragged into the concrete legal system, and have it, you know, ask something of you.
Sometimes academics are hard on ourselves in that we think we put in all this work and do all this writing and no one actually reads it. And that’s not true. People do read your work when you publish it and you should think about who those people might be. They might be district attorneys for the state of California. People will use your work, and you should think from the outset about what the social implications of that might be. It was a big lesson for me.
At the end of the book, you write that your experiences in the cactus and succulent community have left you with hope that meaningful change is possible “not through the repressions of desire but through its celebration.” After spending so much time among people that some might call poachers, what makes you optimistic?
We have so many examples from other illicit economies where prohibition doesn’t work. I am concerned by a tendency to move in that direction. Given that we’re talking about plants — you know, as far as we know, this conversation could be different in 50 years — but we’re not having to really think about the welfare issues of, say, illegal trade in animals. There are pragmatic solutions to these problems. This material could get out into the world so that people who want these plants can get it in a way that doesn’t harm wild-growing species.
There’s still a ways to go in working through regulatory conventions to support those efforts. And importantly, in doing so, supporting the people who should have the most support, which I would argue are the communities in places in the world that have lived with these plants the longest.
I see hopeful promise in this, and I saw a whole lot of love. I really did. I saw a lot of love between people and plants, and what that can do for people in moving into developing more careful relations with plants and other species. I don’t have a large collection of cacti and succulents, but I do have some, and I have like a cactus right now that’s in flower. Do you want to see it?
Yes!
This is where I think it’s fun, to think about what plants can teach us—
Oh, it’s gorgeous!
This is a Mammillaria laui. Named for Alfred Lau, who I write about in one of the chapters of the book — a German who lived in Mexico, who has a lot of different species named after him. This is Mammillaria laui, subspecies subducta. It’s got this gorgeous crown of pink flowers.
I love having these plants. Specifically, I’ve started a small collection of plants that are associated with particular people that I wrote about, or that I thought about. Bringing some of that social history to our plants, I think, is a really nice thing that people can do. Learn about where our plants come from and the histories of how they got to where we are.
That’s kind of what set me off on this whole journey, anyway. I think there’s a lot of opportunity for thinking thoughtfully about the place of these plants in the world and how they travel and maybe, hopefully, that can help move us towards a more ethical kind of relation.
Are you worried now that once you collect all of the plants that are connected to your book, you’ll throw your whole collection out?
I don’t think I have a strong collector tendency, per se. I have been accused of being a low-key hoarder before. I’m excited to think about how I’m going to slowly develop a collection over time. Yeah, but your reference — the worst thing that can happen to a collector is completing a collection. Freud wrote about this in the context of completing his collection of statues and dying days later. This one collector who I went to see, I thought I was going to see a giant greenhouse of cacti, but I found a bunch of Mexican chili plants. Because he’d just tossed [the cacti collection] off, he was done with it. I don’t see myself going down that road but one never knows.
For someone reading this interview who might be interested in collecting, where would you say to start?
We need to get over this idea that cacti and succulent plants are great house plants because they don’t require any care. It’s not true. Everyone I know who’s had a succulent has killed it very quickly.
I killed mine.
Yeah, if you just throw a succulent on, like, a north-facing windowsill, it’s not going to do well, especially if you ignore it.
Also, get over the idea that there are natural people in the world with a green thumb — I think that is also nonsense. We just need to spend time learning about what these plants need. One of the ways you can do that is by paying attention to them.
In terms of obtaining material — you know, so much plant material can also just be found for free, gifted from friends or colleagues or the community. A lot of collector clubs, like, say, the Cactus and Succulent Society of America here in the U.S., I believe may even send you free seeds of cacti, and stuff like that.
The thing that I want to start doing is trying to grow cacti from seed. They’re slow-growing plants but I think it’d be really fun to actually watch that process unfold. And it’s quite easy to obtain seeds for a lot of these plants. Just, you know, be careful where you’re buying stuff from. Reputable nurseries are a good source. But be wary of buying from unknown people on the internet. That might be where people start to get into trouble.
Is there anything I haven’t asked you about that you’d like to let me know about your book or your experience writing it before I let you go?
I’m not too prescriptive at the end of the book about what I think the answer is. Some people may find that frustrating, like, “Oh, but you didn’t tell us like what should we do” or “What’s the right response?” One of the reasons for that was I just wanted to let people develop some of their own thoughts about this. But also it’s because the work isn’t done.
I’m developing some work right now dealing with illegal succulent trade in South Africa with some colleagues, both in South Korea but also in South Africa. I’m doing a new project on illicit Venus flytrap harvesting and the carnivorous plant trade. I’m trying to continue the process of thinking and learning with plants. But the work continues.

And data centers might be collateral damage.
After derailing gigawatts of renewable power with a permitting freeze, the Trump administration is expanding its war on renewable energy, retaining one of country music’s biggest stars in a PR offensive against utility-scale projects on “prime farmland.”
The administration recently onboarded John Rich – one half of the stadium-packing American musical duo Big & Rich – to be Trump’s “special envoy for American landowners.” Rich entered activism around landowner rights last January when he backed opponents fighting a large Tennessee Valley Authority transmission project routed through his home county of Cheatham, Tennessee. This led to him joining the Trump team, where he’s fashioning himself as a go-to guy and cheerleader for anyone who wants Trump to help stop a solar or wind farm they don’t want built.
Rich’s first fight on behalf of the Trump team? Battling solar projects in upstate New York. Over the weekend, Agriculture Secretary Brooke Rollins, EPA Administrator Lee Zeldin, and the freshly-annointed Rich wrote New York Governor Kathy Hochul grilling her on the state’s definition of “prime farmland” and claiming “the absence of a clear plan” for disposing of solar panels after projects are decommissioned. The letter resulted from Rich’s conversations with a prominent anti-solar Substack author in upstate New York, Alexandra Fasulo, and it references a specific Repsol project under development in Glen, New York, that she is fighting in state court.
“Only 8 weeks ago, I decided to start posting my written content from Facebook and Substack to X. It didn’t take long before John Rich and I connected,” Fasulo wrote in a blog on Monday. “John and I spoke on the phone a few times. We texted and I began to share my research with him. Many meetings later… and the US Department of Agriculture, the Environmental Protection Agency (EPA), and John Rich put their heads together.” In her post Fasulo signaled more is coming. “If you read the letter slowly, you’ll get the gist of what the feds are trying to do here. For legal purposes, I am not going to explain that in writing. Read between the lines,” she said. “This lays the foundation for battling destruction at the hands of solar and wind complexes, battery storage, and so much more. Have a little faith and patience. There is A LOT to come.”
Trump is pivoting to farmland fights because there are few battlegrounds left for the federal government to fire upon. He has totally undermined large-scale renewable energy development in the ocean – I mean, look at offshore wind. He’s wrecked progress in the desert, where large solar farms on federal lands remain trapped in bureaucratic permitting delays. Some facilities are now getting through, like Primergy Power’s Purple Sage Energy Center south of Pahrump, Nevada, which got its permits last month. Yet other large projects are petering out; permitting on at least three large solar proposals – Smith Blythe’s Desert Energy Charger Project and Intersect Power’s Perkins Renewable Energy Project in California and Balanced Rock Power’s Samantha Solar effort in Nevada – has been paused or canceled outright since the start of the year.
The president’s turn to fighting projects on farmland also makes sense from a political standpoint. He’s facing an enormous backlash to a buildout of hyperscale data centers he supported, many of which are sited on acreage suitable for agriculture. Republicans running statewide in must-watch midterms battlegrounds – Texas and Iowa, for example – will have to navigate this rocky terrain where something their president supported is deeply unpopular. By bringing Rich aboard and letting him wail on renewable energy in the public square, it’ll be a signal that the Big Man is still listening to rural MAGA voters wary of industrial development.
In media interviews, Rich has claimed Trump created this new, unpaid special envoy position after the country star turned down an offer to sit on the TVA. “I said [to Trump], ‘if I serve with the TVA I cannot disparage the TVA, and I fully intend on keeping my right to disparage them intact.’” He said, ‘You know what, I respect that. So what do you want to do?’ And I said, ‘Man, give me a position where I’ve got some authority and I can work with the highest agencies in the land to protect landowners. Can you create something like that for me?’”
That’s at least the public story for how the president created the “special envoy” role, which Rich has described in ways that are equal parts citizen-government liaison and culture warrior. It’s now clear from his many posts on X that he’ll be heavily involved in messaging against the construction of new renewable energy facilities, carbon pipelines and, potentially, hyperscale data centers.
“[I’ll] go out, find these egregious situations where landowners are being infringed upon and I can go in, work with USDA, EPA, Secretary of the Interior, HUD, the Energy Department, and then all the way of course [to] the Oval Office – to throw up a defense against American landowners,” Rich told Atkisson. He added that data centers will also be a focus of his in government, and there are “two or three” projects out there where he wanted to intervene.
“The president wants to see the data centers built, but he also wants the farm and ranchland to be preserved. We have to have food security for America. We have to.”
Rich and Fasulo then joined Rollins and other administration officials at a press conference Thursday in Washington, D.C. Fasulo spoke at length against New York solar and wind development. Pressed on how data centers square with farmland protection, Rollins spoke about the anxiety in rural America around hyperscalers.
“That debate is raging right now,” she said. “I think that the importance of private property rights, the importance of preserving American farmland, the importance of ensuring we’re going to have another 250 years of freedom is paramount. Does that mean it is completely incompatible with data centers? I don’t think so and I know President Trump doesn’t think so. But what it does mean is that we have to be extremely intentional. There should be plenty of land in this country where data centers can be built that will not be on prime, important farmland. That’s my take on that.”
When Rich joined the federal government is unclear. The Agriculture Department formally announced Rich joined the administration on June 10, but Rich first disclosed Trump “made an offer for a position” in a subscriber-only post made to X on July 24, 2025. He then provided updates in similarly paywalled statements, revealing the Trump appointment to his subscribers in April. Then in May, he told subscribers that he’d completed federal onboarding. “I’m really looking forward to pushing bad guys off of good guys’ land:) You’ll be seeing the official announcement soon, but I wanted you to know 1st!”
What’s clear, however, is that Rich has other targets too. As Rich was brought into federal service, he began routinely sharing a URL – “usda.gov/lawfare” – and directed aggrieved landowners to report potential misdeeds around land seizure. A review of his back-and-forth communications on social media indicate several potential fights he may wade into. Wind energy projects in Kansas. Solar development in rural Virginia. An aluminum smelter in Oklahoma. Carbon capture proposals in Louisiana.
Prior to formally joining the administration, Rich got involved in a conflict over eminent domain and transmission for data centers in Coweta County, Georgia, which had gone viral on right-wing social media. On May 12, Rich said he “just had a great phone call” with Rep. Brian Jack, the GOP congressman who represents the transmission battleground in question. “I will be speaking more on the matter soon,” he tweeted, declaring the power lines threatened “not only homes, but cattle farms and row crops.” Rich also says he facilitated federal engagement between the USDA and Casey Murph, a rancher in Navajo County, Arizona, who claims the state prematurely ended a land lease he held so Orsted can build a solar project.
It’s also apparent Rich will be the first major Trump administration official to publicly root for more counties to indefinitely ban solar and wind development. “The best way for farm and ranch land to be protected from wind/solar projects is for the county to pass a moratorium on those energy sources, disallowing them to ever be built in the county,” Rich told an X follower on May 16.
No one can predict how harmful it’ll be to have one of country music’s most famous artists turning into a spokesperson against renewable energy. But I doubt even paying Katie Miller to say nice things about solar will be able to overcome newly-empowered activism from a Nashville legend.
And more of the week’s top news around project fights.
1. Kansas City, Missouri – Data centers are so toxic that politicians are using them as boogeymen in totally unrelated policy discussions.
2. Ingham County, Michigan – We have our first major anti-data center candidate in a Democratic congressional primary.
3. Nueces County, Texas - The Longhorn State is on a bull run towards data center hostility.
4. Pulaski County, Arkansas - We have yet another municipal employee losing their job over helping a data center.
5. Marathon County, Wisconsin - Yet again rural residents are poised to lose against state permitting primacy laws benefiting renewable energy.
This week’s conversation is with Grant Gutierrez, head of community impacts at carbon management company Carbon Direct. This week Carbon Direct published a white paper Gutierrez authored on opposition around data centers he’s studied. His research reinforces much of what Heatmap Pro has uncovered, but I was particularly intrigued by a topline finding – that transparency is the most common thread in the 46 data center fights he looked into. Was he seeing what I’ve been seeing? So I asked him to hop onto a Zoom call and let me know his thoughts.
The following conversation was lightly edited for clarity.
If you were to explain the findings in your white paper to someone at a bar… how would you put it?
What I would say is that we were really interested in the kinds of concerns communities were articulating as they were opposing or resisting data center development in the U.S. To answer and explore those questions, we developed our own data center cancellation tracker where we looked for cases where we could find a strong correlation between cancelation or withdrawal status and opposition. Then we did high-level analyses of the demographics surrounding those data centers, using standard best practices from environmental justice methodologies and pulling sociodemographic and environmental burden characters from EPA’s EJScreen tool. We were mostly looking at public records. Press materials. City council meeting minutes. Things you wouldn’t have to dig too hard to find.
The kinds of communities we saw successfully resisting data centers tracked across the demographic middle of the United States – slightly more middle income, slightly more white than a majority of the American community, but mostly what you’d consider the average American community.
What is the intended audience of this paper and what are you hoping to communicate?
I think it’s important for data center developers and the capital behind them is that they need to move their engagement to early stage, responsible design. A second audience is regulators, city councils, and local zoning commissions about how to engage with developers and advocate for the right disclosure requirements from industry.
The key topline message is that developers who treat community engagement as a permitting formality instead of a critical early stage input are burdening communities, breaking trust. This is resulting in reputational risk for developers, stranded assets, losing capital – and the loss of future opportunities as developers want to build 21st century infrastructure.
Walk me through what you saw evaluating these projects. What’s the development pattern that leads to such opposition?
We saw five key themes. Some of them you might expect – concerns around natural resources, water impacts, electricity rates, land. The rural character came up quite consistently. And then there was a lack of transparency through the use of NDAs.
The NDA example I was surprised to see was the most consistent in all of our case studies. Communities are largely concerned with the process that unfolds as much as the impacts. That’s a very important signal that transcends political lines. Communities want to be heard, involved in the process. They want large infrastructural development with impacts to listen to their concerns. When those decisions are made behind NDAs or with no transparency or equitable engagement, communities quickly mobilize and organize at a hyperlocal level and are successful in opposing these data centers.
I know there are a number of companies out there – without naming names – that are putting responsible development principles forward. The ones we advocate for across our business, whether we’re working in carbon removal or other things. I see companies leading and saying, if we’re involved in this infrastructure, we are not going to sign an NDA. Those who are pushing forward renewable energy commitments, community benefit agreements, and local public-private partnerships are leading with transparency and equity in their engagements.
How any of this carries in the broader industry is yet to be seen.
In your report you point to various ways opposition can crop up to a project. One of those ways was due to the presence of co-located gas – you note that gas power at a data center engendered environmental opponents, which then strengthened those fighting a data center. Can you elaborate on whether you think a new gas power presence is making it harder to get a data center built?
The case you’re pointing to, that’s the Ballico case where on top of the data center there was a 3,500 megawatt co-located gas plant. That quickly led to major community concerns and a partnership with the Southern Environmental Law Center, which became the legal anchor for thinking through the opposition here and commissioned the technical evidence, and provided the legal [support] there.
You see a broad coalition coalesce around not only the data center concern but the climate concerns that arise. I wouldn’t be surprised if we saw a repeated concern around the expansion of fossil energy and combustion sources going hand in hand with community opposition and organizing on data centers. But that remains to be seen.
What in your research have you seen when you compare opposition to data centers and campaigns against, let’s say, fossil fuels? Or mining? Or renewables?
What I think about with data centers is they’re the highways of the 21st century. As we know through the highway projects in the U.S., there were major disproportionate impacts on communities of color. I think there’s potential for data centers if they follow that playbook to have that same impact.
When it comes to comparing these, that’s something I have not done yet. But I think there’s a few things happening. I think the scale and scope of the buildout is taking the American public by surprise. Articulation around impacts to natural resources and electricity prices in a heightened political climate and a difficult economy. It’s also the existential problem AI introduces, which is the role AI plays in society. This is unique compared to other kinds of extraction, which feed technologies already at play.
How do you feel about the fact that so many of us in energy, environment and climate are now talking about data centers all the time?
Never in my career, working in carbon removal and nature based solutions, I never thought data centers would be a major focus in my career as an environmental justice advocate and social scientist.
Data centers are probably emerging to be one of the biggest environmental justice problems of our time so while it’s not something I planned to work on, I am emboldened to see the response from the nonprofit community and others trying to wrap their heads around this. What is the right kind of information? What does the public need to know? How do we advocate for our communities and build the world we would like to build?
While data centers are moving fast, I’m encouraged to see communities organizing and advocating for their own needs as well. Over the next few years, the story will tell itself.
Last question – what was the last song you listened to?
