Monitoring Aquatic Habitat Restoration using High-Resolution Multispectral Remote Sensing
(University of Oregon, 2019-09-18) Baldwin, Daniel; McDowell, Patricia
The restoration of riverine habitats is a widespread industry valued at millions of dollars annually. Quantifying the success of river restoration projects is an important component of restoration planning but is often impractical in the long term. This study uses cheaply available consumer grade technology to monitor a restoration site on the Middle Fork John Day River, Oregon, and evaluate changes using 3 sets of high-resolution imagery over a 12-year period. Additionally, it explores the experimental generation of submeter resolution NDVI imagery though a modified consumer grade camera. This study finds that restoration is moving towards its intended goals. Riparian vegetation has generally expanded and encroached on the channel within the study site, and that the most vigorous vegetation is that which has been protected from deer and elk browse in addition to cattle grazing removal. Wood structures have remained relatively stable.
