J. Swift&#8217;s novel When There Are Wolves Again, the Chernobyl disaster and its legacy are translated into a near future where natural habitats are diminished and unstable. <\/p>\n<p>This work of ecofiction deftly explores the question of possible paths forward for the return of animals to areas of reduced natural habitat. In the real world, a parallel version of this story unfolds as nature flourishes around a former nuclear power plant. <\/p>\n<p>This is especially true at the former Chernobyl nuclear power plant in Ukraine, where, 40 years after the nuclear disaster, the absence of human activity has allowed wildlife to thrive despite continued radiation. <\/p>\n<p>Following the world&#8217;s worst civilian nuclear disaster at Chernobyl in 1986, a 2,600 square kilometer exclusion zone was established. The accident released a radioactive cloud across Europe, and approximately 115,000 people were evacuated from surrounding areas. Almost immediately, 31 factory workers and firefighters died from radiation poisoning.<\/p>\n<p>40 years since the Chernobyl disaster, which led to the creation of the Chernobyl Exclusion Zone (CEZ). Since 1986, the site has unintentionally been transformed into a thriving wildlife sanctuary and vast rewilding \u201claboratory.\u201d A CEZ prohibits people living there, commercial activities, natural resource extraction, and public access. Today, this region is home to many large mammals.<\/p>\n<p>The population of wolves, foxes, lynx, elk and wild boar has increased significantly here. Meanwhile, species such as brown bears and European bison have returned. Given the inability of humans to intervene, this is rewilding in its most extreme form and has some unintended consequences for the CEZ.<\/p>\n<p>Research shows that hunting, agriculture, and lack of development by humans have a more positive impact on animal populations than the negative effects of radiation. <\/p>\n<p>The population of large mammals in the Belarusian part of this zone is equal to or even higher than the population in uncontaminated nature reserves. There is no doubt that the early radiation caused great damage to flora and fauna, especially the &#8220;Red Forest&#8221;, a 10 square kilometer area near the nuclear power plant. <\/p>\n<p>The area got its name from the pine trees that absorbed so much radiation that they withered and turned reddish-brown. However, long-term studies show that biodiversity increased in the absence of humans.<\/p>\n<figure class=\"align-center zoomable\">\n<div class=\"placeholder-container\" style=\"--aspect-ratio-percent:66.57824933687002%;--background-color:#4f5233\"><\/div><figcaption>\n              <span class=\"caption\"\/><br \/>\n              <span class=\"attribution\"><span class=\"source\">Imago\/Alamy<\/span><\/span><br \/>\n            <\/figcaption><\/figure>\n<h2>Revival of rare species<\/h2>\n<p>Various endangered species have returned to the exclusion zone. This includes Przewalski&#8217;s horse, which was reintroduced in 1998 as a conservation experiment. They are currently breeding and their population has increased to more than 150 individuals within certain areas of the Ukrainian region. <\/p>\n<p>Both the Eurasian lynx and European bison, which had disappeared from the region, have returned and established populations. Several different bird species have returned, including the wood stork, black stork, and white-tailed eagle.<\/p>\n<figure>\n<p><iframe loading=\"lazy\" title=\"The Dark Secret of Chernobyl&#039;s Black Frogs#ChernobylFrogs#RadiationEvolution#SurvivalAdaptation\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/bamso6UEzXE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p><figcaption><span class=\"caption\">Chernobyl black frog.<\/span><\/figcaption><\/figure>\n<p>Most importantly, the globally endangered Great Spotted Eagle is back. Great spotted eagles rely on wetland habitat for hunting and are highly sensitive to human disturbance. It disappeared from this area at the time of the nuclear accident. <\/p>\n<p>In 2019, four pairs were recorded in the study area, and at least 13 pairs were recorded nesting in the Belarusian part of the area. Today, this region is the only place in the world where the population of this rare species is increasing.<\/p>\n<h2>frog changes color<\/h2>\n<p>There is also scientific evidence that some species appear to be adapted to radioactive environments. For example, tree frogs in this zone appear to be darker in color because high melatonin levels protect them from radiation damage. <\/p>\n<p>It appears that wolves have also evolved resilience, as research on Eurasian wolves shows potential adaptations to withstand chronic radiation and reduce cancer risk. <\/p>\n<p>Such adaptations are not limited to animals. Black fungi were first discovered in 1991 using remotely controlled robots growing inside reactor 4 of the former power plant. They appear to grow faster than normal by using melanin, which protects them from UV rays, and converting gamma rays into energy.<\/p>\n<figure>\n<p><iframe loading=\"lazy\" title=\"The Chernobyl Disaster: How It Happened\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/f5ptI6Pi3GA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p><figcaption><span class=\"caption\">What happened in the Chernobyl nuclear power plant accident?<\/span><\/figcaption><\/figure>\n<p>Additionally, some plants in nearby zones have shown DNA repair in response to high levels of radiation. Such adaptations mean plants have evolved to survive, with some plants having an enhanced ability to cope with heavy metals and radiation.<\/p>\n<p>Today, it is one of the largest nature reserves in Europe and an important site for ecological research, particularly on how ecosystems recover when left undisturbed. <\/p>\n<p>This zone was undoubtedly formed by radiation, but also, crucially, by abandonment and time. As a result, normal ecological rules no longer apply, meaning that Chernobyl is now home to some remarkable wildlife. For example, hundreds of pet dogs abandoned in the aftermath of the disaster became stray dogs that have evolved to be genetically distinct from populations in other parts of Ukraine.<\/p>\n<p>Despite the evidence supporting rewilding here, it is clear that not all consequences of disasters are beneficial for plants and animals. There are evolutionary pressures in some species due to lower reproductive success and higher mutation rates, resulting in animal health problems.<\/p>\n<p>But Chernobyl is not the only place where these nuclear zones are encouraging animals to return. Mammals such as bears, raccoons and wild boars have returned in large numbers around other damaged reactors, such as the Fukushima nuclear power plant, turning exclusion zones into unexpected sanctuaries. Some operating nuclear power plants support local wildlife through habitat creation and protection of large, undisturbed exclusion zones.<\/p>\n<p>It is clear that the situation is complex, and it would not take a nuclear disaster to stop humans from endangering the survival of other species, let alone the continued environmental degradation around the world. There are lessons to be learned from such a disaster, but even 40 years after the disaster, no clear conclusions have been drawn. <\/p>\n<p>Although not predictably or evenly, the absence of humans has caused a large portion of wildlife to return to the area around Chernobyl. But it shows how ecosystems can respond and still thrive even when normal rules don&#8217;t apply.<\/p>\n<\/p><\/div>\n<p>#foxes #bears #bison #Chernobyl #years #disaster<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In E.
