Animal life thriving around Fukushima: Researchers document more than 20 species in nuclear accident zone:

The camera study, published in the Journal of Frontiers in Ecology and the Environment, reports that over 267,000 wildlife photos recorded more than 20 species, including wild boar, Japanese hare, macaques, pheasant, fox and the raccoon dog -- a relative of the fox -- in various areas of the landscape.

UGA wildlife biologist James Beasley said speculation and questions have come from both the scientific community and the general public about the status of wildlife years after a nuclear accident like those in Chernobyl and Fukushima.

This recent study, in addition to the team's research in Chernobyl, provides answers to the questions.

"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," said Beasley, associate professor at the Savannah River Ecology Laboratory and the Warnell School of Forestry and Natural Resources.

Species that are often in conflict with humans, particularly wild boar, were predominantly captured on camera in human-evacuated areas or zones, according to Beasley.

"This suggests these species have increased in abundance following the evacuation of people."

The team, which included Thomas Hinton, professor at the Institute of Environmental Radioactivity at Fukushima University, identified three zones for the research.

Photographic data was gathered from 106 camera sites from three zones: humans excluded due to the highest level of contamination; humans restricted due to an intermediate level of contamination; and humans inhabited, an area where people have been allowed to remain due to "background" or very low levels of radiation found in the environment.

The researchers based their designations on zones previously established by the Japanese government after the 2011 Fukushima Daiichi accident.

For 120 days, cameras captured over 46,000 images of wild boar. Over 26,000 of those images were taken in the uninhabited area, compared to approximately 13,000 in the restricted and 7,000 in the inhabited zones.

Other species seen in higher numbers in the uninhabited or restricted zones included raccoons, Japanese marten and Japanese macaque or monkeys.

Anticipating questions about physiological condition of the wildlife, Hinton said their results are not an assessment of an animal's health.

"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 Hinton.

The uninhabited zone served as the control zone for the research.
