Startling Discovery

The study found that there were more than 20 species of animal life that were thriving in the areas surrounding the Fukushima exclusion zone. This discovery is even despite the lingering amount of radiation that exists in the area, according to other environmental studies.

“Our results represent the first evidence that numerous species of wildlife are now abundant throughout the Fukushima Evacuation Zone, despite the presence of radiological contamination,” James Beasley, a wildlife biologist who co-authored the study, said in a press release about the study.

More About The Study

The zones had different features and areas. Because Fukushima is a place with vast amounts of mountains and other kinds of terrains, the scientists wanted to determine how the wildlife interacted with the various environments within the natural habitat.

“The terrain varies from mountainous to coastal habitats, and we know these habitats support different types of species. To account for these factors, we incorporated habitat and landscape attributes such as elevation into our analysis,” Beasley said.

A Unique Pattern

Researchers from the University of Georgia stated that the photographic evidence in the study revealed that the animals observed returned to behaviors that were known based on their history and behavioral pattern.

The animals acted like they typically did before the disaster struck. Raccoons are nocturnal by nature, and they were shown to be active during the night while pheasants performed their usual daily routines.

The Results

The researchers dissected the behaviors of all of the creatures that were captured in the images and determined that much of the wildlife carried on similarly to what they did before the natural disaster. The results showed that very few deviated from what was typically expected from them.

What makes these results exciting is the relatively short amount of time that the area seems to be bouncing back from the contamination of the Fukushima Daiichi nuclear plant disaster. Even those that may have adapted differently also had exciting results to reveal.

Wild Boars

Another compelling aspect found in the study is the behavior of the wild board that lived inside the uninhabited area. The boar was just one of the animals that presented an even more interesting aspect to the disaster aftermath environmental study, especially considering that they are often at conflict with human involvement.

In the study, wild boards that were in the uninhabited area were more active during the day while those that resided in the human-inhabited areas. It suggests that the boars were modifying their behavior when there were no humans around. Their absences made the diurnal creatures more active during daylight hours.

Serows

There was another example found in the study that differentiated between its typical patterns following the Fukushima Daiichi nuclear plant disaster. Researchers noted that the Japanese serow was one of the few exceptions to that rule.

The Japanese serow is like a goat. It is medium-sized and can be found grazing on rocky hills. Based on this new research, these animals were more frequently seen on the camera footage in rural human-inhabited upland areas. The experts believe that the serows made a behavioral adjustment because of the boar population that had grown in the evacuated zone.

Study Of Animal Behavior

The research conducted by the University of Georgia is an example of animal behavior, which is known as a cornerstone of experimental psychology. It hopes to shed light on how animals interact with each other and their environments and help humans understand why they behave in the ways that they do.

“This research makes an important contribution because it examines radiological impacts to populations of wildlife, whereas most previous studies have looked for effects to individual animals,” said Professor Thomas Hinton.

Further Research Is Needed

The photographs used in the study were not able to indicate whether any of the animals had been physically affected as a result of the nuclear plant disaster radiation. Other studies had shown that there were several deformed butterflies identified. The insects had more massive legs and smaller wings than those that were found outside in the no-gone zone.

Those studies revealed that the animals that lived in Fukushima are having to adapt and change as a result of their surroundings. It is up to other scientists to determine what other ways the animals had to change because of the disaster.

More Research

Scientists said there is no previous data on wildlife populations in the evacuated areas as well as proximity and similar landscapes. The level of human activity, elevation, and type of habitat were some of the primary factors in influencing how the animals would react.

The knowledge learned from this research could also be adapted toward other studies from similar disasters, including the other significant nuclear disaster, to receive the highest rating. The promise of new life was also revealed in studies from there.

Just Like Chernobyl

The nuclear disaster at Fukushima Daiichi has seen a similar resurgence to the one that occurred in Chernobyl. The area impacted by its own disaster is currently inhabited with brown bears, bison, wolves, and lynxes.

One fascinating case there is the Przewalski horse, which was thought to have been extinct before it was seen around Chernobyl around 1998. There have also been more than 200 bird species returning to the area.

More Life Promises In Chernobyl

The promise of new life after a catastrophic event like the ones in Chernobyl and Fukushima Daiichi provide new hope that life does go on even after the direst of circumstances occur. Several other studies have noted how different kinds of animals have returned to their once natural habitat.

“Relative abundances of elk, roe deer, red deer and wild boar within the Chernobyl exclusion zone are similar to those in four (uncontaminated) nature reserves in the region and wolf abundance is more than seven times higher. Additionally, our earlier helicopter survey data show rising trends in elk, roe deer, and wild boar abundances from one to ten years post-accident,” according to a 2015 study.

Impact On The Absence Of Humans

The amounts of radiation had little influence on how the wildlife was distributed. While the contaminated areas had some dangerous amounts of radiation, they were also void of any human interaction. The researchers surmise that because humans were not present for large amounts of time, the animals were able to adapt to the changes in the habitat.

“Over time, some wildlife species have responded favorably to the absence of humans, even in the presence of high radiation levels, resulting in a rewilding of the evacuation zones,” Dr. Thomas Hinton told Earther.

Examples Of Radiation Changes

Radiation is not without its damages. There were several birds and mammals found in areas contaminated from a nuclear disaster to have born or developed with significant health conditions. Some have cataracts in their eyes, smaller brains, deformed sperm, tumors, or other abnormalities. 

These conditions are a direct result of ionizing radiation and how it can scramble a creature’s DNA. The further away from the contamination, the more likely that these defects would be less pronounced. The full effects of radiation on animal reproductivity remain unknown at this time.

Living Life

Despite the handicaps that were caused by a human-made disaster, several animals of all shapes and sizes continue to maintain viable and growing populations. For example, several birds have also set up their nests near the decrepit nuclear plant at Fukushima.

“Although it may seem counter-intuitive, research from our group and others suggests numerous species of large mammals actually increased in the landscape surrounding Chernobyl in the first several years after the accident, and that populations of many species are now abundant and widespread throughout the Chernobyl Exclusion Zone,” Beasley told Newsweek.

The Radiation

Because the amount of released from the Fukushima Daiichi power plant was lower than those emitted at Chernobyl, the scientists are not surprised that there is a vibrant resurgence in life now in the environment.

“Given that the amount of radiation released from the Fukushima Daiichi power plant was substantially lower than releases at Chernobyl, it is not surprising that we are now seeing evidence of these same types of population-level responses in mammals at Fukushima,” the study said.

The Return Of Human Life

While wildlife has returned to both Chernobyl and Fukushima, humans who once lived in the area have been more resistant. The Japanese government has allowed people to return to the evacuation zones since as soon as 2016, but only a small percentage have come back.

Experts have indicated that less than three percent of the area impacted by the nuclear disaster continues to be off-limits. Much of the public trust remains tentative, and the first residents to come back did not return until 2019.

Fukushima’s Comeback

The good news for the area is that the Fukushima area can be posed for a comeback. The place used to be a tourist attraction for many visitors, known for its beautiful autumn colors, historic sites, and mountainous backdrops. However, the concern for radiation has caused the tourism industry to dwindle.

The change in perception is something that will come with time, and experts state the upcoming Olympics games in Tokyo could be a step in the right direction in convincing humans that they could be inhabited again, just like the wildlife and other animals have already discovered.
