Pairing fish and habitat data at multiple spatial scales and life stages is difficult, time consuming, and often an expensive task in fisheries research. With the advent of remote sensing technologies like Light Detection and Ranging (LiDAR) and drone mounted sampling instruments (e.g., multispectral sensors and high-resolution red, green, blue (RGB) cameras) becoming more affordable and accessible, our ability to map rivers and assess fish/habitat continuously across the riverscape is ever improving. To further utility of drone mounted sensors, Biomark Applied Biological Services (ABS) collected and paired roughly 20 kms of high-resolution stream imagery, mark-recapture fisheries data, and minimal on-the-ground habitat sampling in 4 reaches across the Upper Salmon River watershed of Idaho. We developed open source scripts and packages in R to semi-automate fish/habitat metric calculations, imagery processing and post processing, and the merger of all data sources from the channel unit to reach scale for analysis and visualization. Further, we continue to apply and progress both RGB, and multispectral imagery processing to aide in analysis of watershed limitations, species life stage limitations, and restoration prioritization in the Upper Salmon Basin, specifically the Lemhi River. Collaboration with multiple agencies across the Pacific Northwest has allowed for this research progression and we look forward to collaborating and applying these techniques with current and future partners.
