One of the weird consequences of this? Leaf litter is two to three times thicker in Chernobyl's most contaminated zones than it is in uncontaminated areas, the researchers found. Check out Smithsonian to learn about what this means for the health of the forest's trees. For a look at how the wildlife of Chernobyl is doing overall, you've got [documentaries](http://www.bbc.co.uk/nature/14306752), books (http://www.amazon.com/Wormwood-Forest-Natural-History-Chernobyl/dp/0309094305), books, and any number of articles to choose from. This Wired feature from 2011 is interesting, focusing on a debate among scientists about how badly, exactly, the wildlife continues to suffer from radioactive isotopes in Chernobyl's soil.
