Milkweed Presence Detection from High-Resolution Mobile Roadway Photography and LiDAR

This project builds on previous Idaho Transportation Department (ITD) studies to identify and map milkweed along highway rights-of-way using existing roadway photography and LiDAR data. The effort will produce a geographic information system (GIS)-based inventory that documents route, milepost, area, and density information for each identified milkweed cluster, supporting ITD’s initiatives to prioritize and preserve high-quality Monarch and pollinator habitat. Key objectives include detecting milkweed using LiDAR and photo imagery, mapping occurrences by route and milepost, estimating cluster size and plant density, and analyzing correlations between milkweed area and density.
