Rich Buckley, a researcher at Rutgers told me that Arthobotrys
(those fungi that lasso and kill phytopathogenic nematodes) are
ubiquitous. In his examination of soils from all over the world, every
sample had them.

great diversity of nematodes. The HJ Andrews is an long term
ecological study site of the NSF, in the mts in Oregon. The forests
around Fort Lewis in Washington State - again, undisturbed - have
good diversity, but be careful of the tanks rolling around. They get
fairly nasty about unauthorized people on the property, so maybe not a
good place to go on your own. And again, you have to know where the
place has not been disturbed. > > So, the best way to

that. Send them to SFI for ID. Or hope for the best in your
compost. >
