Because of increasing anthropic pressure from factors such as damming or climate change, they are often endangered and suffer from a drop in groundwater accessibility and increased water stress. By combining hyperspectral, LiDAR, and forestry datasets along a 20 km corridor of the Ain River, this paper assesses the ability of remote sensing to characterize and monitor such environments. These datasets are used to investigate changes in site conditions and forest characteristics, such as height and canopy water content, along a gradient of ecosystem ages and for reaches under distinct geomorphic conditions (shifting, sediment-starved, incised). The data show that, over time, forest patches aggrade, and the forest grows and becomes more post-pioneer. However, forest patches that are located in the incised reach aggrade more and appear to be less developed in height, more stressed, and feature species compositions reflecting dryer conditions, in comparison with better-connected patches of the same age. Random forest analysis was applied to predict the indicators of forest connectivity with remotely sensed LIDAR and hyperspectral data, in order to identify the spatial trends at the reach scale and compare them with the geomorphic segmentation of the river. The random forest classifications achieved an accuracy between 80% and 90% and resulted in spatial trends that highlighted the differences in hydrological connectivity between differing geomorphic conditions. Overall, remote sensing appears to be a good tool for characterizing the impact of channel incisions and adjustments on riparian forest conditions by identifying the locations of dryer forest patches. In addition, good accuracy was achieved when attempting to classify these forest patches, even when using hyperspectral data alone, which suggests that satellite data could become a powerful tool for monitoring the health of riparian forests, in the context of increasing anthropic pressures.<\/jats:p>","DOI":"10.3390\/rs15010017","type":"journal-article","created":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T03:59:26Z","timestamp":1671595166000},"page":"17","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Combining Hyperspectral, LiDAR, and Forestry Data to Characterize Riparian Forests along Age and Hydrological Gradients"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8203-288X","authenticated-orcid":false,"given":"Julien","family":"Godfroy","sequence":"first","affiliation":[{"name":"CNRS, UMR 5600 Environnement Ville Soci\u00e9t\u00e9, ENS de Lyon, University of Lyon, F69342 Lyon, France"}]},{"given":"J\u00e9r\u00f4me","family":"Lejot","sequence":"additional","affiliation":[{"name":"CNRS, UMR 5600 Environnement Ville Soci\u00e9t\u00e9, University of Lyon, Universit\u00e9 Lumi\u00e8re Lyon 2, F69342 Lyon, France"}]},{"given":"Luca","family":"Demarchi","sequence":"additional","affiliation":[{"name":"Institute of Geodesy and Geoinformatics, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland"},{"name":"Planetek Italia s.r.l., 70132 Bari, Italy"}]},{"given":"Simone","family":"Bizzi","sequence":"additional","affiliation":[{"name":"Department of Geosciences, University of Padova, 35122 Padua, Italy"}]},{"given":"Kristell","family":"Michel","sequence":"additional","affiliation":[{"name":"CNRS, UMR 5600 Environnement Ville Soci\u00e9t\u00e9, ENS de Lyon, University of Lyon, F69342 Lyon, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3864-2119","authenticated-orcid":false,"given":"Herv\u00e9","family":"Pi\u00e9gay","sequence":"additional","affiliation":[{"name":"CNRS, UMR 5600 Environnement Ville Soci\u00e9t\u00e9, ENS de Lyon, University of Lyon, F69342 Lyon, France"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"289","DOI":"10.2307\/1467295","article-title":"The Potential Importance of Boundaries to Fluvial Ecosystems","volume":"7","author":"Naiman","year":"1988","journal-title":"J.
