Hi Matt, I would at least boil them in order to get read of all/most of the bacteria, fungi and small bugs (parasite) that they contain. It is unlikely however that these critters would survive in an aquatic medium if you collected the leaves on land. If collected in swamps, river bed, wet banks, ponds, etc.. i would think that their hosts would be adapted to living under water and would therefore be more of a threat. I think that boiling them will also remove some of the tanin they contain, so if you are choosing them for that aspect more than for the habitat (and look) they will create, do not boil them for too long. Boiling them would also make them sink. have a good we c ya Yvan Alleau 450 SE Atwood Ave Corvallis, OR 97333 (541) 752-0320 College of Oceanic and Atmospheric Sciences Oregon State University Burt 222: (541) 737-3649 "When you're far from everything, you're getting closer to the essential" -----Original Message----- From: owner-apisto@admin.listbox.com [mailto:owner-apisto@admin.listbox.com]On Behalf Of Matt & Linda Crocker Sent: Sunday, December 22, 2002 9:31 AM To: apisto list Subject: leaf prep(sterilization) I have more oak leaves than I can use, and more than I want to rake. Do these need to be sterilized? Or just use them right out of the yard?
