8 Conservationists Convicted of Spying in Iran
By Kayleigh Long
A court in Tehran last week delivered a guilty verdict in the case of eight Iranian conservationists accused of spying, with sentences ranging from four to 10 years. The eight were all affiliated with the Persian Wildlife Heritage Foundation (PWHF), a Tehran-based conservation organization that works to save the critically endangered Asiatic cheetah (Acinonyx jubatus venaticus) and other species.
PWHF founder Morad Tahbaz and program manager Niloufar Bayani both received 10-year sentences, while cheetah researcher Houman Jowkar and biologist Taher Ghadirian were sentenced to eight years each. Coordinator Sepideh Kashani, big cat conservationist Amirhossein Khaleghi Hamidi and former PWHF staffer Sam Radjabi received six years, while Abdolreza Kouhpayeh, a conservationist and wildlife photographer, received four years.
The conservationists have been imprisoned since their arrests in January 2018. PWHF's volunteer managing director, Kavous Seyed-Emami, a Canadian-Iranian sociology professor, was arrested at the same time. He died the following month in Evin Prison in Tehran. Iranian authorities claimed the death was a suicide and have not permitted an independent investigation, according to Seyed-Emami's family.
Four of the group had faced charges of "sowing corruption on earth," which can carry the death penalty, but these were dropped in October. According to New York-based NGO Human Rights Watch, the eight were ultimately convicted of "collaborating with the enemy state of the United States." The charges appear to be related to allegations that the conservationists used wildlife camera traps for the purpose of espionage.
The sentences, handed down on Nov. 20 and 23, came amid a sweeping internet blackout and protests around the country, precipitated by an increase in fuel prices. The Center for Human Rights in Iran, an advocacy group based in New York, reported that the eight were given the verdicts verbally, rather than in writing, which it described as "a common practice in politically motivated cases in Iran."
A close relative of one of the jailed PWHF staff who requested anonymity due to the sensitivity of the situation told Mongabay that the conservationists and their supporters were reacting to the verdicts with "despair, and yet determination." The relative noted that the conservationists have 20 days to lodge an appeal. "From the conservation community, we hope to see very strong reactions," the relative said. "This is now a conviction and no longer a projected outcome, which was something that some parts of the conservation community was waiting for to react on. Here it is. This could be any one of them working to save our planet … This should be a real serious alarm."
Foreign and Domestic Responses
The group's jailing in 2018 met with international criticism, and news of the verdict and sentences sparked a fresh outcry from human rights and conservation organizations, including the New York-based Wildlife Conservation Society, Human Rights Watch, and the IUCN.
"Sentencing innocent wildlife conservationists to long jail sentences in the absence of evidence is a travesty of justice and a violation of multiple human rights," said David Boyd, the U.N. Special Rapporteur on human rights and the environment, in a statement emailed to Mongabay. "In the context of a global biodiversity crisis the work of these conservationists should be admired, not condemned. An appeal should be expedited and their sentences should be overturned."
The secretary-general of the Geneva-based human rights NGO the International Commission of Jurists, Sam Zarifi, said that while his group hadn't been able to monitor the case due to access restrictions, it did appear there were flaws in the judicial process. "Based on publicly available material, their trial at Branch 15 of the Revolutionary Court suffered from serious due process problems, including defendants' lack of access to lawyers of their choosing, lack of access to the indictment and underlying evidence, and claims by the defendants that they were tortured in order to provide false confessions," Zarifi told Mongabay by email.
"There is no publicly available indication that the defendants' claims were investigated properly. So looking at this case from the outside — which is unfortunately as close as we can get — their trial doesn't seem to have been a fair or credible process," he said.
The U.N. Environment Programme (UNEP) issued a statement voicing deep concern and calling for clemency. UNEP also confirmed that convicted PWHF program manager Bayani had been a UNEP consultant between 2012 and 2017. Bayani and PWHF founder Tahbaz, a successful businessman, were reportedly also charged with "gaining illegitimate income," with Bayani reportedly ordered by the court to repay the salary she had earned consulting with UNEP.
The case has also raised questions domestically. In November 2018, more than 1,100 conservationists in Iran signed an open letter addressed to the head of the judiciary. They emphasized that over some 20 years of professional interactions the detained conservationists were only known "for serving [their] country and trying their best to protect its nature."
Senior government officials have gone on record saying that investigations had failed to turn up evidence that the detained were spies.
While no evidence has been made public, one key line of pursuit during interrogations was reportedly the link between PWHF and the founder of the world's largest big cat conservation organization, Panthera, headquartered in New York. PWHF staff occasionally worked alongside experts from Panthera, using camera traps to monitor cheetah populations. The conservation community has spoken out strongly against the notion that low-quality motion-sensor camera traps could serve any espionage purpose.
The founder of Panthera, U.S. billionaire Thomas Kaplan, is active in and provides funding to United Against Nuclear Iran (UANI), a New York-based lobby group that advocates for tough sanctions and regime change in Iran. The group pushed for the U.S. to withdraw from the Iran nuclear deal, formally the Joint Comprehensive Plan of Action (JCPOA), which it did in May 2018.
In late 2017, PWHF staff reportedly sought to distance themselves from Panthera following a speech by Kaplan that comprised his first major public show of support for UANI. A letter from PWHF to Panthera voiced "alarm and consternation" at his political activities. Panthera has issued no response to the arrests or verdict and did not respond to requests from Mongabay for comment.
PWHF's central mission was the conservation of the critically endangered Asiatic cheetah. Just 50 remain in the world, all of them in Iran. Jowkar, the jailed PWHF cheetah researcher, led the latest IUCN assessment of the species, in 2008. He, Ghadirian and Khaleghi Hamidi were members of the IUCN/SSC Cat Specialist Group, and PWHF had been instrumental in highlighting the plight of the species through a project funded by Iran's Department of Environment and the U.N. Development Programme (UNDP).
The jailed conservationists also worked to protect other species and to raise awareness on environmental issues in a country beset by drought. Ghadirian, PWHF's consultant on large mammals from 2014 to 2017, undertook population surveys of leopards, wolves and bears using camera traps, tracking, urine and other signs. He worked with herders to find solutions to human-animal conflict.
On one of the few phone calls permitted to loved ones from prison, Ghadirian reportedly asked what was going on in his absence with a project on Baluchistan bears (Ursus thibetanus gedrosianus), a critically endangered subspecies of the Asian black bear. He and another biologist had been working in southern Iran to raise awareness of the importance of conserving the species, reduce human-bear conflict and livestock depredation, and push for the establishment of wildlife corridors and a protected area.
David Garshelis, a bear specialist with the Minnesota Department of Natural Resources and member of the IUCN/SSC Bear Specialist Group, said the research was showing real promise. "Before they started, it wasn't actually clear that there were still bears in this area," he said.
"[Ghadirian] was very concerned about both sides of the equation, both people and bears," and sought to address conservation issues holistically, said Garshelis. "He was in elementary schools giving programs, then talking to people in the field — he was trying to address it from every possible level."
Garshelis said he had hoped to visit and work with Ghadirian on the bear project. "We were thinking things might ease up, sometime in the future," he said.
In addition to the jail time, the eight are all reportedly banned from working in the conservation sector for two years from the conclusion of their sentences.

Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean and South America.
Blackpoll warbler. PJTurgeon / Wikipedia<p>We used this information to determine how the number of migratory bird species varies based on each city's level of <a href="https://www.britannica.com/science/light-pollution" target="_blank" rel="noopener noreferrer">light pollution</a> – brightening of the night sky caused by artificial light sources, such as buildings and streetlights. We also explored how species numbers vary based on the quantity of tree canopy cover and impervious surface, such as concrete and asphalt, within each city. Our findings show that cities can help migrating birds by planting more trees and reducing light pollution, especially during spring and autumn migration.</p>
Declining Bird Populations<p>Urban areas contain numerous dangers for migratory birds. The biggest threat is the risk of <a href="https://doi.org/10.1650/CONDOR-13-090.1" target="_blank">colliding with buildings or communication towers</a>. Many migratory bird populations have <a href="http://dx.doi.org/10.1126/science.aaw1313" target="_blank">declined over the past 50 years</a>, and it is possible that light pollution from cities is contributing to these losses.</p><p>Scientists widely agree that light pollution can <a href="https://doi.org/10.1073/pnas.1708574114" target="_blank">severely disorient migratory birds</a> and make it hard for them to navigate. Studies have shown that birds will cluster around brightly lit structures, much like insects flying around a porch light at night. Cities are the <a href="https://doi.org/10.1002/fee.2029" target="_blank" rel="noopener noreferrer">primary source of light pollution for migratory birds</a>, and these species tend to be more abundant within cities <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.13792" target="_blank" rel="noopener noreferrer">during migration</a>, especially in <a href="https://doi.org/10.1016/j.landurbplan.2020.103892" target="_blank" rel="noopener noreferrer">city parks</a>.</p>

The Power of Citizen Science<p>It's not easy to observe and document bird migration, especially for species that migrate at night. The main challenge is that many of these species are very small, which limits scientists' ability to use electronic tracking devices.</p><p>With the growth of the internet and other information technologies, new data resources are becoming available that are making it possible to overcome some of these challenges. <a href="https://doi.org/10.1038/d41586-018-07106-5" target="_blank">Citizen science initiatives</a> in which volunteers use online portals to enter their observations of the natural world have become an important resource for researchers.</p><p>One such initiative, <a href="https://ebird.org/home" target="_blank" rel="noopener noreferrer">eBird</a>, allows bird-watchers around the globe to share their observations from any location and time. This has produced one of the <a href="https://doi.org/10.1111/ecog.04632" target="_blank" rel="noopener noreferrer">largest ecological citizen-science databases in the world</a>. To date, eBird contains over 922 million bird observations compiled by over 617,000 participants.</p>
Light Pollution Both Attracts and Repels Migratory Birds<p>Migratory bird species have evolved to use certain migration routes and types of habitat, such as forests, grasslands or marshes. While humans may enjoy seeing migratory birds appear in urban areas, it's generally not good for bird populations. In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. As scientists, we're concerned when we see evidence that migratory birds are being drawn away from their traditional migration routes and natural habitats.</p><p>Through our analysis of eBird data, we found that cities contained the greatest numbers of migratory bird species during spring and autumn migration. Higher levels of light pollution were associated with more species during migration – evidence that light pollution attracts migratory birds to cities across the U.S. This is cause for concern, as it shows that the influence of light pollution on migratory behavior is strong enough to increase the number of species that would normally be found in urban areas.</p><p>In contrast, we found that higher levels of light pollution were associated with fewer migratory bird species during the summer and winter. This is likely due to the scarcity of suitable habitat in cities, such as large forest patches, in combination with the adverse affects of light pollution on bird behavior and health. In addition, during these seasons, migratory birds are active only during the day and their populations are largely stationary, creating few opportunities for light pollution to attract them to urban areas.</p>
Trees and Pavement<p>We found that tree canopy cover was associated with more migratory bird species during spring migration and the summer. Trees provide important habitat for migratory birds during migration and the breeding season, so the presence of trees can have a strong effect on the number of migratory bird species that occur in cities.</p><p>Finally, we found that higher levels of impervious surface were associated with more migratory bird species during the winter. This result is somewhat surprising. It could be a product of the <a href="https://www.epa.gov/heatislands" target="_blank">urban heat island effect</a> – the fact that structures and paved surfaces in cities absorb and reemit more of the sun's heat than natural surfaces. Replacing vegetation with buildings, roads and parking lots can therefore make cities significantly warmer than surrounding lands. This effect could reduce cold stress on birds and increase food resources, such as insect populations, during the winter.</p><p>Our research adds to our understanding of how conditions in cities can both help and hurt migratory bird populations. We hope that our findings will inform urban planning initiatives and strategies to reduce the harmful effects of cities on migratory birds through such measures as <a href="https://www.arborday.org/programs/treecityusa/index.cfm" target="_blank" rel="noopener noreferrer">planting more trees</a> and initiating <a href="https://aeroecolab.com/uslights" target="_blank" rel="noopener noreferrer">lights-out programs</a>. Efforts to make it easier for migratory birds to complete their incredible journeys will help maintain their populations into the future.</p><p><em><span style="background-color: initial;"><a href="https://theconversation.com/profiles/frank-la-sorte-1191494" target="_blank">Frank La Sorte</a> is a r</span>esearch associate at the </em><em>Cornell Lab of Ornithology, Cornell University. <a href="https://theconversation.com/profiles/kyle-horton-1191498" target="_blank">Kyle Horton</a> is an assistant professor of Fish, Wildlife, and Conservation Biology at the Colorado State University.</em></p><p><em></em><em>Disclosure statement: Frank La Sorte receives funding from The Wolf Creek Charitable Foundation and the National Science Foundation (DBI-1939187).

Editor's note: This story is part of a nine-month investigation of drinking water contamination across the U.S. The series is supported by funding from the Park Foundation and Water Foundation. Read the launch story, "Thirsting for Solutions," here.
In late September 2020, officials in Wrangell, Alaska, warned residents who were elderly, pregnant or had health problems to avoid drinking the city's tap water — unless they could filter it on their own.
Unintended Consequences<p>Chemists first discovered disinfection by-products in treated drinking water in the 1970s. The trihalomethanes they found, they determined, had resulted from the reaction of chlorine with natural organic matter. Since then, scientists have identified more than 700 additional disinfection by-products. "And those only represent a portion. We still don't know half of them," says Richardson, whose lab has identified hundreds of disinfection by-products. </p>
What’s Regulated and What’s Not?<p>The U.S. Environmental Protection Agency (EPA) currently regulates 11 disinfection by-products — including a handful of trihalomethanes (THM) and haloacetic acids (HAA). While these represent only a small fraction of all disinfection by-products, EPA aims to use their presence to indicate the presence of other disinfection by-products. "The general idea is if you control THMs and HAAs, you implicitly or by default control everything else as well," says Korshin.</p><p>EPA also requires drinking water facilities to use techniques to reduce the concentration of organic materials before applying disinfectants, and regulates the quantity of disinfectants that systems use. These rules ultimately can help control levels of disinfection by-products in drinking water.</p>
Click the image for an interactive version of this chart on the Environmental Working Group website.<p>Still, some scientists and advocates argue that current regulations do not go far enough to protect the public. Many question whether the government is regulating the right disinfection by-products, and if water systems are doing enough to reduce disinfection by-products. EPA is now seeking public input as it considers potential revisions to regulations, including the possibility of regulating additional by-products. The agency held a <a href="https://www.epa.gov/dwsixyearreview/potential-revisions-microbial-and-disinfection-byproducts-rules" target="_blank">two-day public meeting</a> in October 2020 and plans to hold additional public meetings throughout 2021.</p><p>When EPA set regulations on disinfection by-products between the 1970s and early 2000s, the agency, as well as the scientific community, was primarily focused on by-products of reactions between organics and chlorine — historically the most common drinking water disinfectant. But the science has become increasingly clear that these chlorinated chemicals represent a fraction of the by-product problem.</p><p>For example, bromide or iodide can get caught up in the reaction, too. This is common where seawater penetrates a drinking water source. By itself, bromide is innocuous, says Korshin. "But it is extremely [reactive] with organics," he says. "As bromide levels increase with normal treatment, then concentrations of brominated disinfection by-products will increase quite rapidly."</p><p><a href="https://pubmed.ncbi.nlm.nih.gov/15487777/" target="_blank">Emerging</a> <a href="https://pubs.acs.org/doi/10.1021/acs.est.7b05440" target="_blank" rel="noopener noreferrer">data</a> indicate that brominated and iodinated by-products are potentially more harmful than the regulated by-products.</p><p>Almost half of the U.S. population lives within 50 miles of either the Atlantic or Pacific coasts, where saltwater intrusion can be a problem for drinking water supplies. "In the U.S., the rule of thumb is the closer to the sea, the more bromide you have," says Korshin, noting there are also places where bromide naturally leaches out from the soil. Still, some coastal areas tend to be spared. For example, the city of Seattle's water comes from the mountains, never making contact with seawater and tending to pick up minimal organic matter.</p><p>Hazardous disinfection by-products can also be an issue with desalination for drinking water. "As <a href="https://ensia.com/features/can-saltwater-quench-our-growing-thirst/" target="_blank" rel="noopener noreferrer">desalination</a> practices become more economical, then the issue of controlling bromide becomes quite important," adds Korshin.</p>
Other Hot Spots<p>Coastal areas represent just one type of hot spot for disinfection by-products. Agricultural regions tend to send organic matter — such as fertilizer and animal waste — into waterways. Areas with warmer climates generally have higher levels of natural organic matter. And nearly any urban area can be prone to stormwater runoff or combined sewer overflows, which can contain rainwater as well as untreated human waste, industrial wastewater, hazardous materials and organic debris. These events are especially common along the East Coast, notes Sydney Evans, a science analyst with the nonprofit Environmental Working Group (EWG, a collaborator on <a href="https://ensia.com/ensia-collections/troubled-waters/" target="_blank">this reporting project</a>).</p><p>The only drinking water sources that might be altogether free of disinfection by-products, suggests Richardson, are private wells that are not treated with disinfectants. She used to drink water from her own well. "It was always cold, coming from great depth through clay and granite," she says. "It was fabulous."</p><p>Today, Richardson gets her water from a city system that uses chloramine.</p>
Toxic Treadmill<p>Most community water systems in the U.S. use chlorine for disinfection in their treatment plant. Because disinfectants are needed to prevent bacteria growth as the water travels to the homes at the ends of the distribution lines, sometimes a second round of disinfection is also added in the pipes.</p><p>Here, systems usually opt for either chlorine or chloramine. "Chloramination is more long-lasting and does not form as many disinfection by-products through the system," says Steve Via, director of federal relations at the American Water Works Association. "Some studies show that chloramination may be more protective against organisms that inhabit biofilms such as Legionella."</p>
Alternative Approaches<p>When he moved to the U.S. from Germany, Prasse says he immediately noticed the bad taste of the water. "You can taste the chlorine here. That's not the case in Germany," he says.</p><p>In his home country, water systems use chlorine — if at all — at lower concentrations and at the very end of treatment. In the Netherlands, <a href="https://dwes.copernicus.org/articles/2/1/2009/dwes-2-1-2009.pdf" target="_blank">chlorine isn't used at all</a> as the risks are considered to outweigh the benefits, says Prasse. He notes the challenge in making a convincing connection between exposure to low concentrations of disinfection by-products and health effects, such as cancer, that can occur decades later. In contrast, exposure to a pathogen can make someone sick very quickly.</p><p>But many countries in Europe have not waited for proof and have taken a precautionary approach to reduce potential risk. The emphasis there is on alternative approaches for primary disinfection such as ozone or <a href="https://www.pbs.org/wgbh/nova/article/eco-friendly-way-disinfect-water-using-light/" target="_blank" rel="noopener noreferrer">ultraviolet light</a>. Reverse osmosis is among the "high-end" options, used to remove organic and inorganics from the water. While expensive, says Prasse, the method of forcing water through a semipermeable membrane is growing in popularity for systems that want to reuse wastewater for drinking water purposes.</p><p>Remucal notes that some treatment technologies may be good at removing a particular type of contaminant while being ineffective at removing another. "We need to think about the whole soup when we think about treatment," she says. What's more, Remucal explains, the mixture of contaminants may impact the body differently than any one chemical on its own. </p><p>Richardson's preferred treatment method is filtering the water with granulated activated carbon, followed by a low dose of chlorine.</p><p>Granulated activated carbon is essentially the same stuff that's in a household filter. (EWG recommends that consumers use a <a href="https://www.ewg.org/tapwater/reviewed-disinfection-byproducts.php#:~:text=EWG%20recommends%20using%20a%20home,as%20trihalomethanes%20and%20haloacetic%20acids." target="_blank" rel="noopener noreferrer">countertop carbon filter</a> to reduce levels of disinfection by-products.) While such a filter "would remove disinfection by-products after they're formed, in the plant they remove precursors before they form by-products," explains Richardson. She coauthored a <a href="https://pubs.acs.org/doi/10.1021/acs.est.9b00023" target="_blank" rel="noopener noreferrer">2019 paper</a> that concluded the treatment method is effective in reducing a wide range of regulated and unregulated disinfection by-products.</p><br>
Greater Cincinnati Water Works installed a granulated activated carbon system in 1992, and is still one of relatively few full-scale plants that uses the technology. Courtesy of Greater Cincinnati Water Works.<p>Despite the technology and its benefits being known for decades, relatively few full-scale plants use granulated active carbon. They often cite its high cost, Richardson says. "They say that, but the city of Cincinnati [Ohio] has not gone bankrupt using it," she says. "So, I'm not buying that argument anymore."</p><p>Greater Cincinnati Water Works installed a granulated activated carbon system in 1992. On a video call in December, Jeff Swertfeger, the superintendent of Greater Cincinnati Water Works, poured grains of what looks like black sand out of a glass tube and into his hand. It was actually crushed coal that has been baked in a furnace. Under a microscope, each grain looks like a sponge, said Swertfeger. When water passes over the carbon grains, he explained, open tunnels and pores provide extensive surface area to absorb contaminants.</p><p>While the granulated activated carbon initially was installed to address chemical spills and other industrial contamination concerns in the Ohio River, Cincinnati's main drinking water source, Swertfeger notes that the substance has turned out to "remove a lot of other stuff, too," including <a href="https://ensia.com/features/drinking-water-contamination-pfas-health/" target="_blank" rel="noopener noreferrer">PFAS</a> and disinfection by-product precursors.</p><p>"We use about one-third the amount of chlorine as we did before. It smells and tastes a lot better," he says. "The use of granulated activated carbon has resulted in lower disinfection by-products across the board."</p><p>Richardson is optimistic about being able to reduce risks from disinfection by-products in the future. "If we're smart, we can still kill those pathogens and lower our chemical disinfection by-product exposure at the same time," she says.</p><p><em>Reposted with permission from </em><em><a href="https://ensia.com/features/drinking-water-disinfection-byproducts-pathogens/" target="_blank">Ensia</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649953730#/" target="_self"></a></p>
