Changes in land use, such as agricultural expansion, have impacted stream systems by modifying discharge, substrate diversity, channel morphology, and nutrient inputs. The Spokane River watershed is heavily impacted by human activity, including urban and agricultural development. Rehabilitation efforts are being organized to reintroduce Salmonidae species in the Spokane River Watershed. The first step of this reintroduction is to perform habitat studies to inform allocation of restoration efforts. As part of this effort, I performed benthic macroinvertebrate surveys throughout the watershed. Fifty sites were sampled during the summers of 2024 and 2025. In each reach, 4 subsamples, each comprising 0.192 m, were collected from the riffles, using a 500 μm mesh D-frame net then combined for preservation. I am analyzing the invertebrate samples for taxonomic and trait composition. Macroinvertebrate traits are increasingly used as a bioassessment tool, as they are directly impacted by abiotic factors within their aquatic environment. Traits for this study include habit (how invertebrates move around their habitat), feeding group (how invertebrates obtain nutrients), voltinism (number of generations per year), and ventilation mechanism (how invertebrates receive oxygen). The community data is being used to compare α and β diversity for taxonomic and functional composition of the invertebrates throughout the watershed. I am using GIS to quantify watershed land use and analyze the relationship between agricultural land use and invertebrate diversity. I hypothesize there will be higher taxonomic and functional diversity at low to moderate intensity of agricultural land use, and low diversity at high intensity of agricultural land use. Preliminary data shows a strong difference in taxonomic composition between stream reaches, with several streams dominated by Diptera populations. This data will provide awareness of the factors impacting invertebrate diversity in our region’s waterways, and support habitat restoration efforts for native salmonids. Additionally, these results will provide insight into the shape of the relationship between agricultural land use and invertebrate diversity.
