As humans were evacuated from the area 22 years ago, animals moved in despite the radiation. The flora and fauna of the Red Forest have been dramatically affected by the radioactive contamination that followed the accident. It seems that the biodiversity of the Red Forest has increased in the years following the disaster. There are reports of higher numbers of mutations in some of the plants in the area, leading to unsubstantiated tales of a "forest of wonders" containing many strangely mutated plants. Specifically, some trees have weirdly twisted branches that do not reach for the sky.
In the years after the disaster, some plants have displayed gigantism, in which the shape of the plants features remain normal, but its size becomes much larger than average. Gigantism and other plant abnormalities of the Red Forest can be found in the most radioactive parts of the zone of alienation.
The site of the Red Forest remains one of the most contaminated areas in the world. However, it has proved to be an astonishingly fertile habitat for many endangered species. The evacuation of the area surrounding the nuclear reactor has created a lush and unique wildlife refuge. In the 1996 BBC Horizon documentary "Inside Chernobyl's Sarcophagus", birds are seen flying in and out of large holes in the structure of the former nuclear reactor. The long-term impact of the fallout on the flora and fauna of the region is not fully known, as plants and animals have significantly different and varying radiologic tolerance. Some birds are reported with stunted tail feathers (which interferes with breeding). Storks, wolves, beavers, and eagles have been reported in the area.  and joint International Atomic Energy Agency/WHO/UNDP press release Chernobyl: The True Scale of the Accident, International Atomic Energy Agency/World Health Organization/United Nations Development Programme, September 5, 2005 (pdf file)
