I investigated the effects of a decade-old wildfire on trophic and food web structure in streams from the Boise National Forest, Idaho. Based on soil instability and burn patterns from a 12-14 year old wildfire complex, I separated 9 streams into 3 ‘conditions’: unburned, burned, and burned/scoured (these experienced a massive scour one year post-burn). I measured light levels, water temperatures, and took samples of fish, invertebrates, primary producers, and organic detritus. I constructed food webs for each stream using stable Carbon-13 and Nitrogen-15 isotope ratios.  I found that unburned and burned streams had lower water temperatures and light levels reaching the water’s surface, compared to burned/scoured ones. Base energy in the unburned and burned streams was derived both from organic detritus and primary production.  In burned / scoured streams, base energy came from in-stream primary producers. Despite different basal energy sources, all 9 streams had 5-6 trophic levels within the food web.  This data suggests stream recovery is dictated by synergy between fire intensity and underlying parent geology. These determine the speed of recovery via the growth of the riparian vegetation. This study demonstrates that the effects of wildfires on streams are still evident a decade after the fires.
