Forests Around Chernobyl Aren't Decaying Properly

An anonymous reader writes "Smithsonian Magazine has an article about one of the non-obvious effects of the Chernobyl nuclear meltdown: dead organisms are not decomposing correctly. 'According to a new study (abstract) published in Oecologia, decomposers—organisms such as microbes, fungi and some types of insects that drive the process of decay—have also suffered from the contamination. These creatures are responsible for an essential component of any ecosystem: recycling organic matter back into the soil. Issues with such a basic-level process, the authors of the study think, could have compounding effects for the entire ecosystem.' The scientists took bags of fallen leaves to various areas around Chernobyl and found that locations with more radiation caused the leaves to retain more than half of their original weight after almost a year. They're now beginning to worry that almost three decades of dead brush buildup is contributing to the area's fire risk, and a large fire could distribute radioactive material beyond Chernobyl's exclusion zone."

      They're not sterile but it's not merely one organism that attaches early to the leaf that is responsible for the decay. It's a collection of different organisms that each take their share of the organic matter for their own needs. Hence the note of various fungi and insects. Notably, a large part of plant root systems are often heavily intertwined with fungi which either directly or indirectly take part in the breakdown of organic matter around the plants. Hence, just dumping soil onto a new area might not be enough.

      To me the more interesting aspect is just how the plants themselves are fairing as one of the major supposed risks of nuclear fallout is precisely the way it results in uptake of dangerous radioactive material into food. But if the root system and fungi system underground have been largely buffered because the surface fungi/insects die before being able to do the necessary processing...then the plants themselves may be perfectly safe to consume (properly rinsed off, of course) but fail to restore themselves which would quickly turn the area into a desert once a fire occurred.
