Earthworms and mycorrhizae
Has anyone read any scientific studies related to earthworms and their negative impact on mycorrhizae fungi? I'm writing a response to a National Park Service environmental impact assessment in which they asserted that this was true.

Really?
Well, aren't earthworms an invasive, introduced species in some places like MN? |

Google works wonders by supplying info . For example:

I am not sure this research is far enough long yet to have quantifiable
results, but it will likely answer the question eventually: http://www.serc.si.edu/labs/plant_ec...corrhizal.aspx (The assertion that the Park Service already has the answer to this question seems a bit far-fetched.)

Thanks for the replies everyone. Interesting articles.
The assertion that the Park Service already has the answer to this question seems a bit far-fetched. Yes. I agree, Dice. I got a chuckle out of your comment. |

Earthworms and mycorrhizae have been cohabiting the same soils
since before mammals evolved. I can see earthworms maybe vacuuming up some filaments from mycorrhizae as they bulldoze through the soil, but that is not likely to kill the fungus. Anyway, you could possibly email the researcher mentioned in that URL above and ask her if she knows of any existing, already completed research that considered the question.
