Wildfires are frequent disturbances in the Western U.S.A. but few studies have examined the long-term effects of fire on stream habitat and the benthic invertebrate community.  We documented fire effects on the macroinvertebrate community in relation to water chemistry, substrate, bankfull width, and periphyton, in six Idaho wilderness streams during 10 pre-fire years and 2, 3, 10, and 13 months post-fire and then annually thereafter for 4 years.  Overall there were no substantial changes in water chemistry, benthic substrate, or bankful width before or after fire.  Periphyton values increased in post-fire streams.  Macroinvertebrates increased in density and biomass post-fire reflecting increases in periphyton.  We used multivariate ordination to examine patterns in macroinvertebrate community structure in pre- and post-fire years and it was highly variable over the 15 year study period; however, conditions in post-fire sample years were more similar to each other than to pre-fire years.  This pattern was primarily driven by an increase in Baetis, Chironomidae, and Tipulidae in post-fire years and mainly by Empididae, Chloroperlidae and Perlodidae in pre-fire years.  Data collected post-fire were more variable than pre-fire data but are starting to return to pre-fire values, suggesting disturbance effects from the fire are becoming mediated.
