Wildfires are natural disturbances that shape landscapes and can alter aquatic ecosystems and communities. Wildfires can be followed closely by flood events that cause debris flows and scouring, potentially compounding effects on aquatic systems. In 2011, the Horseshoe 2 Fire of southeast Arizona burned over 90,000 hectares of forest and was followed by massive monsoonal rains. These rains triggered flood events that scoured creek beds within the range. In one stream within the affected area, East Turkey Creek, we monitored the aquatic macroinvertebrate community both pre- and postfire. Sampling began in 2007 and continues twice a year in three sites along the stream. We found that taxonomic richness was significantly reduced postfire,
