The 2018 Vaia storm, felled large volumes of timber in Italy causing serious ecological and financial losses. Remote sensing is fundamental for primary assessment of damages and post-emergency phase. An explicit estimation of the timber loss caused by Vaia using satellite remote sensing was not yet undertaken. In this investigation, three different estimates of timber loss were compared in two study sites in the Alpine area: pre-existing local growing stock volume maps based on lidar data, a recent national-level forest volume map, and an novel estimation of AGB values based on active and passive remote sensing. The compared datasets resemble the type of information that a forest manager might potentially find or produce. The results show a significant disagreement in the different biomass estimates, related to the methods used to produce them, the study areas characteristics, and the size of the damaged areas. These sources of uncertainty highlight the difficulty of estimating timber loss, unless a unified national or regional European strategy to improve preparedness to forest hazards is defined. Considering the frequent impacts on forest resources that occurred in the last years in the European Union, remote sensing-based surveys targeting forests is urgent, particularly for the many European countries that still lack reliable forest stocks data.<\/jats:p>","DOI":"10.3390\/rs13234924","type":"journal-article","created":{"date-parts":[[2021,12,6]],"date-time":"2021-12-06T03:10:38Z","timestamp":1638760238000},"page":"4924","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Estimated Biomass Loss Caused by the Vaia Windthrow in Northern Italy: Evaluation of Active and Passive Remote Sensing Options"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6728-3557","authenticated-orcid":false,"given":"Gaia","family":"Vaglio Laurin","sequence":"first","affiliation":[{"name":"DIBAF, Department for Innovation in Biological, Agro-Food, and Forest System, Via San Camillo de Lellis snc, 01100 Viterbo, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2142-959X","authenticated-orcid":false,"given":"Nicola","family":"Puletti","sequence":"additional","affiliation":[{"name":"CREA-FL, Council for Agricultural Research and Economics, Research Centre for Forestry and Wood, 52100 Arezzo, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1555-5669","authenticated-orcid":false,"given":"Clara","family":"Tattoni","sequence":"additional","affiliation":[{"name":"DiSTA\u2014Dipartimento di Scienze Teoriche ed Applicate, Universit\u00e0 degli Studi dell\u2019Insubria, 21100 Varese, Italy"},{"name":"DAGRI Dipartimento di Scienze e Tecnologie Agrarie, Alimentari Ambientali e Forestali, Universit\u00e0 degli Studi di Firenze, 50127 Firenze, Italy"}]},{"given":"Carlotta","family":"Ferrara","sequence":"additional","affiliation":[{"name":"CREA-FL, Council for Agricultural Research and Economics, Research Centre for Forestry and Wood, Via Valle della Quistione 27, 00166 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4796-6406","authenticated-orcid":false,"given":"Francesco","family":"Pirotti","sequence":"additional","affiliation":[{"name":"Department of Land, Environment, Agriculture and Forestry (TESAF), University of Padua, Viale dell\u2019Universit\u00e0 16, 35020 Legnaro, Italy"},{"name":"CIRGEO, Interdepartmental Research Center of Geomatics, University of Padua, Viale dell\u2019Universit\u00e0 16, 35020 Legnaro, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Giannetti, F., Pecchi, M., Travaglini, D., Francini, S., D\u2019Amico, G., Vangi, E., and Cocozza, C.
