Benthic filter feeders are essential in stream ecosystems as they control nutrient cycling and are excellent indicators of stressors that affect ecosystems. A recent study at Fort Hunter Liggett showed a potential decrease in benthic macroinvertebrate filter feeders among different sites studied. To determine if an increase in fine sediment (<2mm) in streams from recent wildfires has affected the number of filter feeders, we conducted a bioassessment at five sites on Fort Hunter Liggett streams following the California SWAMP protocol. We subsampled these samples, to a total of 600 or more organisms from each site. We identified each taxon’s functional feeding groups (FFGs) and then compared both FFG and sediment data from the 5 post-fire sites with an additional 6 sites sampled before the 2020 Dolan/Coleman wildfire, using published data. The results show an increase in substrate (<2mm) has a small to moderate correlation with a decrease in filter feeders. However, there is not a significant increase in fine sediment when comparing sites from before and after the wildfire. In addition, there was an unexpected overall increase in the proportion of filter feeders after the fire compared to before, which could be due to an increase in nutrients flowing downstream from the burned areas. Overall, the potential for positive impacts on filter feeder populations due to wildfire should be considered in future studies as more research is conducted about wildfires in California, a fire-prone state.
